EBB Kitchen Knife

Summary

Long session implementing the kitchen knife weapon for Emoji Ball Battles, plus removing the saw weapon and fixing a boomerang debug issue. The kitchen knife went through many major design iterations: Isaac's Mom's Knife-style throw/return → bouncing off walls like bullets → physics-based impulse throw → sticking on first wall hit with multi-knife accumulation system. Bleed status effect was fully implemented then reverted. A dying_knife visual class was created for parallel wall hits (inspired by Super Emoji Invaders). Melee weapons can now parry thrown knives.

Saw Removal:

Boomerang Debug Fix (Hit Effects in Wrong Position):

Kitchen Knife Design Discussion:

Kitchen Knife First Implementation (Throw/Return):

Wall Stick + Spin + Gradual Speed (Second Iteration):

Bleed Status Effect (Implemented Then Reverted):

Throw/Return Separate Damage Scaling:

Checkpoint Commit: 88dea52 Kitchen Knife checkpoint — committed before major rework.

Major Rework: Bouncing Knife (Third Iteration):

Physics-Based Throw (Fourth Iteration):

Wall Sticking Fixes (Many Iterations):

No Bounces (Final Design):

Multi-Knife Accumulation System:

Sound Effects:

Parallel Wall Hit → Dying Knife (from Super Emoji Invaders):

Visual Feedback Polish:

Enemy Weapon Changed: Default from 'boomerang' to 'sword'.

Knife Parry by Melee Weapons:

Stuck Knives Ignore Weapon Collisions:


Let's continue with EBB. First, let's remove the saw, I didn't like how it turned out. Then, let's think about which weapon to implement next. I think the Kitchen Knife makes sense, since from what I remember it had similar behavior to the boomerang where it went forward then back? But I don't remember exactly. @emoji-ball-battles\docs\ATTACK_REFERENCE.md

Let me get acquainted with the codebase first.

Okay, I've read through all the saw-related code. Here's what needs to be removed:

Saw code locations:

That's quite a lot of places. Before I do the removal, let's discuss the Kitchen Knife.


Looking at the ATTACK_REFERENCE, there's no "Kitchen Knife" listed there. The boomerang (🪃) is listed as:

A "Kitchen Knife" (🔪) could work similarly — a thrown blade that goes forward and returns. But it could also be differentiated. A few directions:

  1. Straight throw + return (like boomerang but straight line, no curve) — simpler trajectory, maybe faster
  2. Forward thrust (like a more stabby sword) — melee, not projectile
  3. Thrown projectile that doesn't return — more like a dagger throw

Do you remember what you had in mind for it? Or should we brainstorm a design that's distinct from the boomerang? The boomerang already covers the "curved throw + return" space pretty well, so a kitchen knife would want to feel different.

AskUserQuestion

User has answered your questions: "What behavior did you have in mind for the Kitchen Knife? Or should we brainstorm something distinct from the boomerang?"="Like Isaac's straight throw then return." user notes: Like Isaac's straight throw then return.. You can now continue with the user's answers in mind.

Got it — like Isaac's Mom's Knife. A straight-line throw forward, then it returns straight back. Much simpler trajectory than the boomerang's curve.

Let me think about how to design this using the attack reference framework:

🔪 Kitchen Knife | | | |---|---| | Shape | S12 Returning Projectile (straight line, not curved) | | Behavior | B2 Triggered-Single (throw, wait for return, cooldown) | | Trigger | T1 Raycast Alignment (fires when knife points at enemy) | | Scaling | ? |

For scaling, a few options that would be visually distinct from boomerang's V7 (+simultaneous):

AskUserQuestion

User has answered your questions: "What scaling should the Kitchen Knife have per hit landed?"="I need to think about it, let's decide later. Do not enter plan mode, do not do everything at once. Do the saw removal first, then let's do the kitchen knife one step at a time." user notes: I need to think about it, let's decide later. Do not enter plan mode, do not do everything at once. Do the saw removal first, then let's do the kitchen knife one step at a time.. You can now continue with the user's answers in mind.

Let me remove the saw. I'll go through each location.

Now let me do a final verification to make sure there are no remaining saw references.

Grep (\bsaw\b|🪚)

No matches found

Clean. All saw references have been removed from main.yue. Here's a summary of what was removed:

  1. Image registrationan\image 'saw'
  2. Sound registrationssaw_hit1, saw_hit2
  3. Collision skip — the continue if attacker.weapon_type == 'saw' in weapon-hitbox handling
  4. Per-frame contact system — the entire 55-line saw DPS loop in arena update
  5. Weapon init — the saw elseif block in ball constructor (25 lines of properties)
  6. Ball drawing — saw rendering case
  7. take_damage — removed saw special-case sound suppression and damage number coloring (simplified to always play sound, always use blue)
  8. weapon_ui image selector — removed saw from the chain
  9. weapon_ui drawing — removed the saw-specific UI rendering block
  10. weapon_ui stats — removed the HIT INTERVAL display
  11. weapon_ui reflect — removed saw-specific hit effect positioning
  12. Default weapon — changed default player weapon from 'saw' to 'dagger'
  13. Headless weapons list — removed 'saw'

The asset files (saw.png, saw_hit1.ogg, saw_hit2.ogg) are still on disk but no longer loaded. You can delete them manually if you want, or leave them.

Go ahead and compile/test, then we can start on the Kitchen Knife.

We need to fix the parry with the boomerang, which is creating hit effects in the wrong positions sometimes. I believe this may be due the incorrect debug drawing. Research how to debug draw the shapes as reported by Box2D directly, instead of using our own variables. We should be able to get a list of vertices or points + radius (for circles) for each shape in world positions, instead of having to calculate how to draw each shape ourselves, I'm pretty sure this exists in Box2D 3.1+

Let me research what's available in the engine's Box2D integration.

Now I have all the information needed. Here's what I found:


Box2D 3.1 provides everything you need. The key functions are:

  1. b2Body_GetShapes(bodyId, shapeArray, capacity) — gets all shape IDs on a body
  2. b2Body_GetShapeCount(bodyId) — how many shapes
  3. b2Shape_GetType(shapeId) — returns b2_circleShape, b2_capsuleShape, b2_polygonShape, or b2_segmentShape
  4. b2Shape_GetCircle(shapeId) — returns b2Circle with .center (local) and .radius
  5. b2Shape_GetPolygon(shapeId) — returns b2Polygon with .vertices[] (local), .count, .radius
  6. b2Shape_GetCapsule(shapeId) — returns b2Capsule with .center1, .center2 (local), .radius
  7. b2Body_GetTransform(bodyId) — returns b2Transform with position + rotation
  8. b2TransformPoint(transform, localPoint) — converts local point to world space

So the approach would be: for each shape on a body, get its type, get its local geometry, then use b2Body_GetTransform + b2TransformPoint to convert each vertex/center to world coordinates. This gives you the exact positions Box2D is using for collision — no manual calculation of offsets needed.

None of these are currently exposed to Lua in your engine. You'd need to add a C function like physics_collider_get_shapes_geometry that:

  1. Gets the body's transform
  2. Iterates shapes on the body
  3. For each shape, gets the type and geometry
  4. Transforms vertices to world space
  5. Returns a Lua table of shapes with world-space points

Alternatively, b2Body_GetWorldPoint(bodyId, localPoint) does the same transform — it's already declared in box2d.h line 260 but not exposed to Lua either.

Want me to add this as a new engine function? Something like collider\get_shape_geometry() that returns a table of shapes with world-space vertices/centers?

Yes.

Let me look at how existing collider functions are structured in the engine to follow the pattern.

Everything compiles and runs. Here's a summary:

Added collider\get_shapes_geometry() — returns a table of all shapes on a body with world-space geometry directly from Box2D.

C function: l_physics_get_shapes_geometry in anchor.c

Framework wrapper: get_shapes_geometry in collider.yue

Return format — table of shape entries, each with:

You can now use this in the game to debug draw the actual Box2D shapes, e.g.:

shapes = @collider\get_shapes_geometry!
for shape in *shapes
  if shape.type == 'polygon'
    -- draw polygon from shape.vertices
  elseif shape.type == 'circle'
    debug_draw\circle shape.x, shape.y, shape.radius, red!

You need to copy anchor.exe here and also collider.yue and any other framework yue files that changed.

Done. Both the ball and projectile debug draws now use get_shapes_geometry to draw the actual Box2D shapes in world space, instead of manually calculating positions from offset variables. This should show you exactly what Box2D sees for collision detection.

Yes, I knew it. The boomerang's shape is not in the right place. There are a bunch of offsets to move the boomerang, but the shape was not moved in the same way, we need to fix that.

Let me look at the boomerang's shape setup vs its visual rendering to understand the mismatch.

Now I see the issue clearly. The visual position uses:

But the hitbox shape uses:

The problem is that weapon_perpendicular_offset (6) and weapon_hitbox_offset_y (8) don't match. But more fundamentally, offset_x in Box2D's add_box is the body-local X offset, and offset_y is body-local Y offset. These correspond to "along the angle" and "perpendicular to the angle" respectively since the body rotates. So the mapping should be:

The perpendicular offset is 6 visually but 8 in the hitbox. That's one mismatch. But let me also check — perpendicular_angle = @angle - math.pi/2, so positive weapon_perpendicular_offset moves in the -pi/2 direction (which in Box2D's local frame would be negative Y if the body's angle convention matches). Let me think about this more carefully.

AskUserQuestion

User has answered your questions: "I can see the mismatch. The visual uses weapon_perpendicular_offset=6 but the hitbox uses weapon_hitbox_offset_y=8. Should I just make the hitbox offset_y match the visual perpendicular offset (change 8 to 6)? Or do you want to tune both values together after seeing the debug draw?"="The visual position of the boomerang is correct, so the shape should match it in all ways." user notes: The visual position of the boomerang is correct, so the shape should match it in all ways.. You can now continue with the user's answers in mind.

Wait — I need to also verify the sign convention. The visual code uses perpendicular_angle = @angle - math.pi/2, and the perpendicular offset is added along that direction. In Box2D's local frame, offset_y positive means the local Y+ direction, which when the body is at angle 0 points downward (positive Y is down in screen space). Let me check whether @angle - math.pi/2 with positive offset_y lines up with Box2D's local Y.

At angle=0:

These are opposite! The visual perpendicular offset moves the boomerang up but the hitbox offset_y moves it down. The fix should be to negate offset_y.

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Actually, wait. Let me verify this more carefully by checking how add_box uses the offset and how the perpendicular visual offset works. Let me re-read the physics_add_box code.

OK so offset_x and offset_y are in pixels, fed to b2MakeOffsetBox as local-space center of the box. offset_x is along the body's local X axis and offset_y is along the body's local Y axis.

In Box2D, when the body is at angle=0:

The visual code: perpendicular_angle = @angle - math.pi/2 weapon_x = @x + actual_offset*cos(@angle) + perpendicular_offset*cos(perpendicular_angle) weapon_y = @y + actual_offset*sin(@angle) + perpendicular_offset*sin(perpendicular_angle)

At angle=0:

So the visual moves the boomerang 6 pixels upward (negative Y). In Box2D local frame, that's offset_y = -6.

My fix of -6 is correct. Let me verify the debug draw will now show the right thing. You can compile and test — the shape should now overlap the boomerang visual.

Your fix is indeed correct, thank you. I added the kitchen_knife image. It's angled downwards like the dagger, but flipped horizontally, so towards the bottom left instead of the bottom right.

Let me look at the dagger's setup to understand the orientation values, since the kitchen knife is similar but mirrored.

So the dagger points bottom-right and uses weapon_rotation_offset = -3*math.pi/4 (which is -135 degrees). The kitchen knife points bottom-left (horizontally flipped), so it's mirrored. To flip horizontally, the rotation offset would be +3*math.pi/4 (or equivalently, negate the x-scale). Let me check how the dagger image gets drawn.

The dagger is drawn at weapon_scale for both X and Y (both positive, 18/512). The weapon_rotation_offset = -3*pi/4 rotates the image so the tip points outward from the ball.

Since the kitchen knife is "flipped horizontally" compared to the dagger (bottom-left instead of bottom-right), the simplest approach would be to negate the x-scale (making weapon_scale negative) which mirrors it horizontally, then adjust the rotation offset accordingly. Or just set a different rotation offset.

Let me check the actual image to understand. Let me look at what image was added.

Good. I can see:

Actually, looking more carefully: the dagger blade goes toward bottom-left of the image, and the kitchen knife blade goes toward bottom-right. So the kitchen knife is indeed the horizontal mirror of the dagger's orientation.

The dagger uses:

For the kitchen knife, to flip it horizontally we can negate weapon_scale_y (flip along the blade axis), which gives:

Or alternatively keep scale_y positive and adjust the rotation. Let me think... Actually the simplest way to confirm is to just present the initial values and let you tune in-game. But based on geometry: if the dagger's tip is bottom-left at -3*pi/4, and the kitchen knife tip is bottom-right, that's a horizontal flip. Negating weapon_scale_y mirrors across the blade's length axis, which should do it.

Here's what I'd propose for the initial kitchen_knife weapon block — basically the dagger but with the y-scale flipped. Does this look right to start with?

elseif @weapon_type == 'kitchen_knife'
  @weapon_class = 'melee'
  @weapon_image = an.images.kitchen_knife
  @weapon_visual_offset = 24
  @weapon_perpendicular_offset = 0
  @weapon_hitbox_offset = 24
  @weapon_hitbox_length = 28
  @weapon_hitbox_width = 8
  @weapon_scale = 18/512
  @weapon_scale_y = -18/512
  @weapon_rotation_offset = -3*math.pi/4
  @base_angular_velocity = 1.5*math.pi
  @max_angular_velocity = 3*math.pi
  @weapon_weight = 1.0
  @hit_stop_multiplier = 1.0
  @hit_particle_multiplier = 1.0
  @camera_shake_multiplier = 1.0

No, don't flip the x scale, make sure you do this with the correct angle instead.

Right. The dagger tip is at bottom-left (~135° from center), so -3*pi/4 rotates it to point outward. The kitchen knife tip is at bottom-right (~45° from center), so the offset should be -pi/4 to point it outward. Both scales positive.

@weapon_rotation_offset = -math.pi/4
@weapon_scale = 18/512
@weapon_scale_y = 18/512

Want me to go ahead and add the full kitchen_knife weapon init block with these values?

Yes.

Let me add it step by step. First the image registration, then the weapon init block.

Done. Added:

Right now it behaves identically to the dagger (continuous melee, same hitbox, same scaling). You can compile and see if the orientation looks correct, then we'll add the Isaac-style throw behavior.

Ah, you need to draw it.

The boomerang sensor events already handle all boomerang_sensor hits. Since the kitchen knife uses the same boomerang_sensor tag, its hits will go through the same event handler. But the scaling logic on line 957 checks for boomerang_damage_triggered — I need to add kitchen knife scaling there too. Let me look at that section more carefully:

The scaling block checks boomerang_damage_triggered which won't exist on a kitchen knife projectile (it has kitchen_knife_damage_triggered). I need to update this to handle both. Since we haven't decided on kitchen knife scaling yet, I'll add the same +1 damage pattern for now using the kitchen_knife fields:

Now I also need to handle the boomerang_projectile wall collision skip for the kitchen knife, and the weapon_hitbox sensor skip. Let me check the weapon_hitbox collision handling:

Finally, handle the plant_ghost sensor events — kitchen knife should interact with plants like the boomerang:

Good — the boomerang_sensor plant_ghost handler at line 1130 already catches all boomerang_sensor events, which includes kitchen knife projectiles since they use the same sensor tag. That's fine.

That should be everything. Let me do a quick verification to make sure I haven't missed anything:

This session is being continued from a previous conversation that ran out of context. The summary below covers the earlier portion of the conversation.

Analysis: Let me go through the conversation chronologically:

  1. Session Start: User wants to continue with EBB (Emoji Ball Battles). Two tasks: remove the saw weapon, then think about implementing Kitchen Knife.

  2. Saw Removal: I read main.yue and identified all saw-related code locations. Removed saw from:

    • Image registration (line 88)
    • Sound registrations (saw_hit1, saw_hit2)
    • Collision skip in weapon-hitbox handling
    • Per-frame contact detection block (~55 lines)
    • Weapon init block in ball constructor
    • Ball drawing
    • take_damage special-case (sound + damage number color)
    • weapon_ui image selector
    • weapon_ui drawing
    • weapon_ui stats (HIT INTERVAL)
    • weapon_ui reflect
    • Default player weapon (changed from 'saw' to 'dagger')
    • headless_weapons list
  3. Kitchen Knife Discussion: User mentioned it should behave like Isaac's Mom's Knife (straight throw then return). Scaling was deferred for later.

  4. Boomerang Debug Issue: User reported parry with boomerang creating hit effects in wrong positions, likely due to incorrect debug drawing. Asked to research Box2D 3.1+ shape geometry API.

  5. Research: I found Box2D 3.1 provides:

    • b2Body_GetShapes(), b2Body_GetShapeCount()
    • b2Shape_GetType(), b2Shape_GetCircle(), b2Shape_GetPolygon(), b2Shape_GetCapsule(), b2Shape_GetSegment()
    • b2Body_GetTransform(), b2TransformPoint()
  6. Engine Function Added: Created l_physics_get_shapes_geometry in anchor.c that:

    • Gets body transform
    • Iterates all shapes via b2Body_GetShapes
    • For each shape, gets type and local geometry
    • Transforms to world space via b2TransformPoint
    • Converts meters to pixels
    • Returns Lua table with type, tag, sensor, and geometry fields
  7. Framework Wrapper: Added get_shapes_geometry to collider.yue

  8. Build + Copy: User reminded me to copy anchor.exe and collider.yue to emoji-ball-battles directory.

  9. Debug Draw Replacement: Replaced manual debug draw calculations in both ball update and projectile update with get_shapes_geometry calls.

  10. Boomerang Fix: User confirmed the debug draw showed the boomerang shape was mispositioned. The issue was:

    • Visual uses weapon_perpendicular_offset = 6 (moves upward at angle=0)
    • Hitbox used weapon_hitbox_offset_y = 8 (moves downward in Box2D local space)
    • Fixed by changing to weapon_hitbox_offset_y = -6 (negative to match the visual direction)
  11. User feedback on approach: When I suggested flipping weapon_scale_y for kitchen knife orientation, user explicitly said "No, don't flip the x scale, make sure you do this with the correct angle instead." I then calculated that kitchen knife needs weapon_rotation_offset = -math.pi/4 instead of dagger's -3*math.pi/4.

  12. Kitchen Knife Image Added: User added kitchen_knife.png. I viewed both images - dagger blade points bottom-left, kitchen knife blade points bottom-right.

  13. Kitchen Knife Weapon Init: Added the weapon init block with -math.pi/4 rotation offset, both scales positive.

  14. Drawing Fix: User pointed out I needed to actually draw the kitchen knife. Added drawing case sharing with dagger initially, then separated to handle kitchen_knife_thrown state.

  15. Kitchen Knife Throw Behavior: Implemented the full Isaac-style throw:

    • Ball side: cooldown, raycast alignment check, fire method (destroy shapes, spawn projectile)
    • Projectile side: straight forward for 0.35s, then straight back toward owner
    • Uses boomerang_sensor tag for ball detection
    • Wall reflection support
    • Catch/recapture with shape recreation
    • Damage on hit with +1 throw damage scaling
    • weapon_ui stat display
    • Skip melee hits (damage from projectile only)

The user's last message before the summary request was just saying the initial implementation looked good (saw removal verified, boomerang fix confirmed correct). The kitchen knife throw behavior was just fully implemented but not yet tested by the user.

Summary: 1. Primary Request and Intent: - Remove the saw weapon entirely from EBB (didn't like how it turned out) - Fix boomerang parry hit effects appearing in wrong positions by implementing Box2D shape debug drawing - Implement Kitchen Knife (🔪) weapon with Isaac's Mom's Knife-style behavior: straight-line throw forward, then straight return back to the ball - User explicitly requested incremental work: "Do not enter plan mode, do not do everything at once. Do the saw removal first, then let's do the kitchen knife one step at a time." - Kitchen knife scaling was deferred: "I need to think about it, let's decide later"

  1. Key Technical Concepts:

    • YueScript game code compiled to Lua, running on the Anchor engine (C + Box2D 3.1)
    • Box2D 3.1 shape geometry API: b2Body_GetShapes, b2Shape_GetType, b2Shape_GetCircle, b2Shape_GetPolygon, b2Shape_GetCapsule, b2Shape_GetSegment, b2Body_GetTransform, b2TransformPoint
    • Pixels-to-meters conversion via pixels_per_meter variable in engine
    • Weapon rotation offset math: dagger tip at bottom-left (~135° from center) uses -3*pi/4; kitchen knife tip at bottom-right (~45° from center) uses -pi/4
    • Projectile system: projectiles are separate physics entities with sensors for ball hit detection
    • Boomerang sensor tag reused for kitchen knife projectiles (same collision handling)
    • Weapon shapes destroyed while projectile is in flight (ball defenseless)
    • Operator spacing convention: * and / no spaces, + and - with spaces
  2. Files and Code Sections:

    • E:\a327ex\emoji-ball-battles\main.yue (primary game code)

      • Saw removal: removed all saw references across ~13 locations (image, sounds, collision handling, weapon init, drawing, take_damage, weapon_ui, headless)
      • Debug draw replaced: manual hitbox calculation replaced with get_shapes_geometry call for both ball and projectile
      • Boomerang fix: weapon_hitbox_offset_y changed from 8 to -6
      • Kitchen knife weapon init block added after boomerang: yuescript elseif @weapon_type == 'kitchen_knife' @weapon_class = 'melee' @weapon_image = an.images.kitchen_knife @weapon_visual_offset = 24 @weapon_perpendicular_offset = 0 @weapon_hitbox_offset = 24 @weapon_hitbox_length = 28 @weapon_hitbox_width = 8 @weapon_scale = 18/512 @weapon_scale_y = 18/512 @weapon_rotation_offset = -math.pi/4 @base_angular_velocity = 1.5*math.pi @max_angular_velocity = 3*math.pi @weapon_weight = 1.0 @hit_stop_multiplier = 1.0 @hit_particle_multiplier = 1.0 @camera_shake_multiplier = 1.0 @kitchen_knife_cooldown = 4.5 @kitchen_knife_thrown = false @kitchen_knife_damage = 1
      • Kitchen knife auto-attack setup (raycast alignment + cooldown)
      • Kitchen knife drawing (hidden when thrown)
      • kitchen_knife_is_aligned method: raycasts from tip to find enemy ball
      • kitchen_knife_fire method: destroys shapes, spawns projectile
      • Kitchen knife projectile init: boomerang_projectile collider tag, boomerang_sensor sensor, speed 400, outward duration 0.35s
      • Kitchen knife projectile update: straight forward, then angle_to_owner on return, catch at distance < 15
      • Kitchen knife projectile drawing: uses kitchen_knife_move_angle + kitchen_knife_rotation_offset for rotation
      • Wall collision: reflects kitchen_knife_move_angle
      • Ball collision: doesn't kill (passes through like boomerang)
      • Damage handling: +1 throw damage on first hit per throw via kitchen_knife_damage_triggered
      • weapon_ui stat display: "THROW DMG"
      • Skip melee hits: continue if attacker.weapon_type == 'kitchen_knife'
      • Default player weapon set to 'kitchen_knife' for testing
      • headless_weapons list updated
    • E:\a327ex\Anchor\engine\src\anchor.c (engine C code)

      • Added l_physics_get_shapes_geometry function (~120 lines) that returns world-space shape geometry from Box2D
      • Registered as physics_get_shapes_geometry in lua_register block
      • Handles circle, polygon, capsule, and segment shape types
      • Includes tag name and sensor boolean per shape
    • E:\a327ex\Anchor\framework\anchor\collider.yue (framework wrapper)

      • Added get_shapes_geometry: => physics_get_shapes_geometry @body method
    • E:\a327ex\emoji-ball-battles\docs\ATTACK_REFERENCE.md (read-only reference)

      • Kitchen knife not listed; boomerang is S12 Returning + B2 Single + T1 Raycast + V7 +Simultaneous
  3. Errors and fixes:

    • Boomerang hitbox offset mismatch: Visual used weapon_perpendicular_offset = 6 (which at angle=0 moves -Y, upward), but hitbox used weapon_hitbox_offset_y = 8 (positive = downward in Box2D). Initially changed to 6, then realized sign was wrong too, changed to -6. User confirmed: "Your fix is indeed correct."
    • Kitchen knife orientation approach: I initially proposed flipping weapon_scale_y to -18/512. User explicitly rejected: "No, don't flip the x scale, make sure you do this with the correct angle instead." Fixed by using weapon_rotation_offset = -math.pi/4 with both scales positive.
    • Missing drawing code: After adding the kitchen knife init block, user pointed out "Ah, you need to draw it." Added the drawing case.
    • File copy missing: After building the engine, user reminded "You need to copy anchor.exe here and also collider.yue and any other framework yue files that changed." Copied both files.
  4. Problem Solving:

    • Saw removal: systematic grep + read + edit across 13 locations, verified clean with final grep
    • Boomerang debug: researched Box2D 3.1 API, added engine function, replaced manual debug draw, identified and fixed offset mismatch
    • Kitchen knife: modeled after boomerang throw pattern but with straight-line trajectory instead of curved arc
  5. All user messages:

    • "Let's continue with EBB. First, let's remove the saw, I didn't like how it turned out. Then, let's think about which weapon to implement next. I think the Kitchen Knife makes sense, since from what I remember it had similar behavior to the boomerang where it went forward then back? But I don't remember exactly."
    • "Like Isaac's straight throw then return." (re: kitchen knife behavior)
    • "I need to think about it, let's decide later. Do not enter plan mode, do not do everything at once. Do the saw removal first, then let's do the kitchen knife one step at a time."
    • "We need to fix the parry with the boomerang, which is creating hit effects in the wrong positions sometimes. I believe this may be due the incorrect debug drawing. Research how to debug draw the shapes as reported by Box2D directly, instead of using our own variables."
    • "Yes." (re: adding get_shapes_geometry engine function)
    • "You need to copy anchor.exe here and also collider.yue and any other framework yue files that changed."
    • "Now use get_shapes_geometry to replace the manual debug draw in main.yue"
    • "Your fix is indeed correct, thank you. I added the kitchen_knife image. It's angled downwards like the dagger, but flipped horizontally, so towards the bottom left instead of the bottom right."
    • "The visual position of the boomerang is correct, so the shape should match it in all ways."
    • "No, don't flip the x scale, make sure you do this with the correct angle instead." (rejected AskUserQuestion about flipping scale)
    • "Yes." (re: adding kitchen knife init block with -pi/4 rotation)
    • "Ah, you need to draw it."
    • "Perfect, I changed the size and offsets a little and now it's fixed. Let's do the throwing behavior now."
  6. Pending Tasks:

    • User needs to test the kitchen knife throw behavior (just implemented, not yet compiled/tested)
    • Kitchen knife scaling decision still deferred ("I need to think about it, let's decide later") — currently using +1 throw damage as placeholder
    • User mentioned wanting to tune values themselves after seeing things in-game
  7. Current Work: Just finished implementing the complete kitchen knife throwing behavior. The full Isaac-style throw-and-return is coded: raycast alignment trigger, straight-line outward flight (0.35s), straight-line return homing to owner, catch/recapture with shape recreation, wall reflection, piercing damage with +1 throw damage scaling, weapon_ui stats, and projectile drawing. The user has not yet compiled and tested this implementation.

  8. Optional Next Step: Wait for user to compile and test the kitchen knife throw behavior, then iterate based on their feedback on feel/tuning. The user explicitly said "let's do the kitchen knife one step at a time" so next steps should follow their lead after testing.

If you need specific details from before compaction (like exact code snippets, error messages, or content you generated), read the full transcript at: C:\Users\adn.claude\projects\E--a327ex\90052d62-60a3-4899-bfa8-ee6cbbd4e170.jsonl Please continue the conversation from where we left off without asking the user any further questions. Continue with the last task that you were asked to work on.

Based on the conversation summary, we just finished implementing the full kitchen knife throwing behavior in main.yue. The implementation includes:

The default player weapon was set to 'kitchen_knife' for testing. You should be ready to compile and test it — let me know how it feels and what needs tuning.

Knife shouldn't reflect on walls, should pierce but remove damage scaling, knife is a melee weapon so it should hit melee, the projectile may be a projectile object but will, for gameplay purposes later, be a melee hit, this doesn't change anything now. Doesn't need to code to not fire while facing walls because its raycast aligned and not based on cooldown like the boomerang.

Got it. Let me find and fix each of those things in main.yue.

Here are the four changes:

  1. Remove wall reflection (lines 3409-3410) — knife passes through walls
  2. Remove damage scaling (lines 962-966) — pierce with base damage only
  3. Remove melee hit skip (line 1063) — kitchen knife hits melee
  4. Remove kitchen_knife_damage variable (line 1510) and update UI/fire to not use it

Let me also check what damage the projectile uses when it hits, so I can clean that up too.

Now remove kitchen_knife_damage from the init block, the fire method's args, and the projectile init, plus clean up the weapon_ui and the kitchen_knife_damage_triggered flag.

Now let me read the fire method to remove the damage arg, and the projectile init to remove the damage tracking.

Now update the weapon_ui to not show "THROW DMG" since there's no scaling. Let me read the current state of that section.

Since there's no damage scaling stat to show, the kitchen knife can fall through to the default (dagger) rotations/s stat display, or we could show something else. But since there's no unique stat, I'll just remove the kitchen_knife-specific UI block and let it fall through to the else (which shows rotations/s — same as dagger, which is fine for now).

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Here's a summary of all the changes:

  1. Removed wall reflection — deleted the kitchen_knife case from the wall hit handler. Knife now passes through walls.
  2. Removed damage scaling — deleted the +1 dmg block from boomerang_sensor hit handling, removed kitchen_knife_damage from init/fire/projectile init, removed kitchen_knife_damage_triggered flag. Projectile damage is now a flat 1.
  3. Removed melee hit skip — kitchen knife now hits melee like other melee weapons. The projectile is also melee for gameplay purposes (no code change needed for that distinction right now).
  4. Removed weapon_ui "THROW DMG" stat — kitchen knife falls through to the default rotations/s display (same as dagger).
  5. Did NOT add wall-facing check — the raycast alignment already handles this naturally.

OK, when the knife hits a wall, it should be stopped there like an arrow, the projectile dies, but the visual stays there for some amount of time. When it comes back, either from wall or normally, it should rotated around itself, direction of rotation based on where it needs to move to reach the player. Finally, the way the velocity stops needs to be more realistic. Currently it stops moving abruptly when it reaches the apex, when it should be a gradual stop and then gradual return acceleration too.

Let me read the full projectile update and hit code for kitchen knife to plan the changes.

Now I have a clear picture. Let me also check what math.angle_to_point returns so I can determine spin direction correctly.

Grep (math.cross|cross_product)

No matches found

OK, here's my plan for all three changes. Let me present the code:

1. Wall hit → stuck knife visual, then return

In the hit() wall handler, instead of doing nothing (since we removed reflect), set a "stuck" state: zero velocity, pause, then start returning.

2. Spinning on return

Add a @kitchen_knife_spin angle that accumulates during return. Spin direction = cross product of current facing vs direction to owner (determines clockwise/counterclockwise).

3. Gradual deceleration/acceleration

Replace the instant speed with a lerp: during the last portion of outward flight, decelerate to 0. During early return, accelerate from 0 to full speed.

Here's the code. First, the projectile init additions:

-- In projectile init for kitchen_knife:
@kitchen_knife_stuck = false
@kitchen_knife_stuck_time = 0
@kitchen_knife_stuck_duration = 0.3
@kitchen_knife_spin = 0
@kitchen_knife_current_speed = @kitchen_knife_speed
@kitchen_knife_decel_duration = 0.15  -- decel at end of outward
@kitchen_knife_accel_duration = 0.2   -- accel at start of return

Then the update logic replaces the current block with gradual speed ramp:

-- Kitchen knife update:
if @kitchen_knife_stuck
  @kitchen_knife_stuck_time += dt
  @collider\set_velocity 0, 0
  if @kitchen_knife_stuck_time >= @kitchen_knife_stuck_duration
    @kitchen_knife_stuck = false
    @kitchen_knife_returning = true
    @kitchen_knife_return_time = 0
elseif not @kitchen_knife_returning
  -- Outward phase: decelerate near end
  remaining = @kitchen_knife_outward_duration - @kitchen_knife_time
  if remaining < @kitchen_knife_decel_duration
    t = math.max(remaining/@kitchen_knife_decel_duration, 0)
    @kitchen_knife_current_speed = @kitchen_knife_speed*t
  else
    @kitchen_knife_current_speed = @kitchen_knife_speed
  if @kitchen_knife_time >= @kitchen_knife_outward_duration
    @kitchen_knife_returning = true
    @kitchen_knife_return_time = 0
else
  -- Return phase: accelerate from 0, spin
  @kitchen_knife_return_time += dt
  if @kitchen_knife_return_time < @kitchen_knife_accel_duration
    t = @kitchen_knife_return_time/@kitchen_knife_accel_duration
    @kitchen_knife_current_speed = @kitchen_knife_speed*t
  else
    @kitchen_knife_current_speed = @kitchen_knife_speed
  angle_to_owner = math.angle_to_point @x, @y, owner.x, owner.y
  @kitchen_knife_move_angle = angle_to_owner
  -- Spin direction: cross product of move_angle vs angle_to_owner
  dx = owner.x - @x
  dy = owner.y - @y
  cross = math.cos(@kitchen_knife_move_angle)*dy - math.sin(@kitchen_knife_move_angle)*dx
  spin_dir = cross >= 0 and 1 or -1
  @kitchen_knife_spin += spin_dir*12*dt

And the wall hit handler:

elseif @projectile_type == 'kitchen_knife'
  @kitchen_knife_stuck = true
  @kitchen_knife_stuck_time = 0
  @kitchen_knife_current_speed = 0

And the drawing uses @kitchen_knife_spin + @kitchen_knife_rotation_offset when returning/stuck, and @kitchen_knife_move_angle + @kitchen_knife_rotation_offset when outward.

Does this look right? A couple things I'm uncertain on:

Do it as is, it all seems good. Except the 0.3s duration should be higher or lower depending on how far along the throw it was.

Good call — early in the throw = more momentum = sticks longer. I'll scale it by (1 - time/outward_duration).

Let me make all the edits.

Projectile init — add new variables:

Good, math.clamp exists. All changes are done. Summary:

  1. Wall hit → stuck then return: On wall collision, knife sticks for 0.3 * (1 - t) seconds where t is how far along the outward throw it was. Early hit = sticks ~0.3s, near apex = barely sticks. Then transitions to return phase.

  2. Spinning on return: kitchen_knife_spin accumulates at 12 rad/s (~2 rotations/sec). Direction determined by cross product of movement vector vs direction to owner. Drawing uses spin + rotation_offset when returning/stuck, move_angle + rotation_offset when outward.

  3. Gradual velocity: Last 0.15s of outward flight decelerates linearly to 0. First 0.2s of return accelerates linearly from 0 to full speed. No more abrupt stop/start.

I think the spinning on return is too fast or it isn't being multiplied by dt.

Let me check the line:

Grep (kitchen_knife_spin += spin_dir)

3332:          @kitchen_knife_spin += spin_dir*12*dt

It is multiplied by dt. So 12 rad/s is just too fast — that's about 2 full rotations per second. Maybe try something like 4 rad/s (~0.6 rotations/sec)?

Edit (E:\a327ex\emoji-ball-battles\main.yue)

Dropped from 12 to 4 rad/s. Let me know if that's still too much or too little.

The knife may be being drawn without taking into account the spin? I don't know, but it seems like there's something else affecting it. When returning, only the spin should affect it.

The drawing looks correct — when returning, r = @kitchen_knife_spin + @kitchen_knife_rotation_offset. But the issue might be the @angle variable. Let me check if there's something updating @angle from the collider velocity further down:

Line 3375 already skips setting the collider angle for kitchen_knife. But line 3378 still reads @angle = @collider\get_angle!. The drawing code uses r not @angle, so that shouldn't matter.

Wait — the drawing uses weapons\push @x, @y, r, s, s. That looks correct. But let me check: is the collider itself rotating? The Box2D body might be rotating from physics forces, and even though we skip set_angle, the body could still have angular velocity from collisions.

The drawing code itself looks correct. The issue is probably that @kitchen_knife_spin starts at 0 but the knife was already facing @kitchen_knife_move_angle during the outward phase. When it switches to return mode, the rotation jumps from move_angle + rotation_offset to 0 + rotation_offset — a big discontinuity. The spin should be initialized to the current move_angle when return starts, so it continues smoothly from there.

There are two places where @kitchen_knife_returning = true is set — the normal apex (line 3314-3316) and the wall unstick (line 3302-3304). Both need to initialize @kitchen_knife_spin to the current @kitchen_knife_move_angle so there's no visual jump.

That should fix it. The problem was that @kitchen_knife_spin started at 0 but the outward phase was drawing at @kitchen_knife_move_angle + rotation_offset. When it switched to return, the rotation jumped from move_angle to 0. Now the spin is seeded with the current move_angle at the moment of transition, so the visual is continuous.

Nope, still wrong. Try to make the returning knife work exactly like the boomerang in terms of its rotation around itself, maybe?

The boomerang is simple: @boomerang_spin just constantly increments at 12*math.pi rad/s every frame, always. No cross product, no direction logic. It spins the whole time — outward and return. The drawing is just @boomerang_spin + @boomerang_rotation_offset.

The kitchen knife should do the same thing on return — just a constant spin, no direction math. Let me simplify:

And the spin should also accumulate while stuck in a wall (same as boomerang would keep spinning):

  3305→            @kitchen_knife_return_time = 0

Actually, while stuck the knife should stay still visually — no spin yet. The spin starts when it begins returning. That's already the case since the drawing condition is @kitchen_knife_returning or @kitchen_knife_stuck. Let me reconsider — while stuck the knife should look stuck (no spin), so let me change the draw to only use spin when returning, not stuck:

Now the spin is just like the boomerang: constant 12*math.pi rad/s (~6 rotations/sec), same speed, starts when returning. No cross product direction logic. Stuck knife stays at its move_angle orientation.

Yes, this works, like the arrow, should be drawn behind the wall. 0.3 -> 0.7 for stuck time.

The stuck_arrow draws on game (the default layer), not weapons. That's what puts it behind walls. Now let me check how the stuck_arrow is spawned — it's added to effects:

Grep (stuck_arrow)

OK so the approach is: on wall hit, spawn a stuck_knife visual effect (like stuck_arrow), and the projectile itself handles the stuck state logic separately. But actually, the current implementation has the projectile staying alive during the stuck phase and then returning. So I need two things:

  1. A stuck_knife visual that draws on game layer (behind walls), blinks, then dies
  2. The projectile itself should still be invisible while stuck, then start returning with spin

Let me create a stuck_knife class similar to stuck_arrow, and spawn it from the wall hit handler. The projectile stays alive but doesn't draw while stuck.

First, the stuck_knife class:

Done. Changes:

I don't think we need stuck knife object, we can just do it on the projectile directly.

You're right, simpler. Draw the projectile on game layer when stuck instead of weapons.

Simplified. Now the projectile just draws on game layer when stuck (behind walls) and weapons layer otherwise. No separate class needed.

Is the knife currently moving forward and back based on initial velocity or time?

Time. The outward phase runs for kitchen_knife_outward_duration (0.35s) then switches to returning. Each frame it sets velocity explicitly via set_velocity — the initial velocity from the spawn is immediately overridden by the update loop.

OK, let's set it to 0.5s, and increase the lerp down + up by 20%.

The held weapon hitbox is 28x8. The projectile is 16x6. Two changes needed:

  1. Match the collider size to the weapon hitbox (28x8)
  2. Set the collider angle each frame to match the visual rotation

Now set the collider angle to match the visual each frame. The visual rotation r is computed in the drawing section — I need to set the collider angle in the update section. Line 3373 already skips kitchen_knife from the default angle-from-velocity logic, so I just need to add the angle set there:

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Done. The projectile collider now:

The angle of the projectile should also match the knife's visual angle when going, and should otherwise track the direction to the player when coming back (not rotate like it does visually).

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Now the collider always tracks move_angle + rotation_offset — which is the visual angle when outward, and the direction to player when returning (since move_angle is set to angle_to_owner each frame during return). The visual spin is purely cosmetic.

There should be no visual effect when the kitchen knife hits the wall, other than it springing (this should be matched on weapon UI). When returning, there should be no effect at all possible with the walls, not even sound.

I see. The collision handler calls hit() (which does the spring + flash), plays a sound, spawns hit_circle and hit_particles, and triggers weapon_ui flash. For kitchen knife:

  1. Outward hit: spring only (from hit()), weapon_ui spring — no sound, no particles, no flash
  2. Returning: skip entirely — no hit, no sound, no anything

Now I also need to make sure the hit() method doesn't trigger stuck state when returning. Let me check:

  3453→          @kitchen_knife_stuck = true
  3454→          @kitchen_knife_stuck_time = 0

The hit() method's wall case still runs the stuck logic. But since the collision handler now continues for returning kitchen knife, hit() won't be called when returning. The hit() stuck logic only triggers when outward — which is correct. But let me also remove the flash from hit() for kitchen knife, since the user said only spring:

  3428→    @spring\pull 'hit', 0.5*intensity, 3, 0.5
  3429→    @flashing = true

The hit() method does both spring and flash. The flash is a visual effect (white blink). The user said "no visual effect other than springing." I should skip the flash for kitchen knife wall hits. But hit() is shared across all projectile types. I can guard it:

Done. Summary:

The actual shape angle is not correct and matching the knife when moving forward, especially when it hits the wall.

The issue is that @kitchen_knife_rotation_offset (-pi/4) is a visual correction for the image, but the collider box should just be aligned with the movement direction. The box at angle=0 is already horizontal — adding the rotation offset skews it -45 degrees from where it should be.

Grep (collider\set_angle @kitchen_knife)

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

The collider box now just follows @kitchen_knife_move_angle directly — long axis aligned with the direction of travel.

Perfect. Now the way we'll scale the knife is that thrown or return hits will be red colored and will apply bleed to the enemy. Read up on how we want status effects to work, there's details in a file somewhere.

Here's what the docs say about Bleed for the kitchen knife:

From WEAPON_DESIGN.md:

From PHASE2_WEAPONS.md:

There's a slight contradiction between the two docs — WEAPON_DESIGN says bleed stacks (counter, consumes 1 per wall hit), while PHASE2 says "single stack, doesn't accumulate." The PHASE2 version seems like the simpler/newer spec.

Also from the weapon tags: 🔪 Kitchen Knife — +chance to apply bleed per hit and the evolution is the throw/return behavior we already built.

So for the kitchen knife specifically:

Before I start implementing, a few questions:

AskUserQuestion

User has answered your questions: "For bleed on the kitchen knife, which spec should we follow? WEAPON_DESIGN says bleed stacks and consumes 1 per wall hit. PHASE2 says single stack, doesn't accumulate, longer duration. Which one?"="You need to tell me about each in more detail, also explain why there are 2 status effect definitions instead of just one, how else do the files differ?" user notes: You need to tell me about each in more detail, also explain why there are 2 status effect definitions instead of just one, how else do the files differ?, "Should melee hits from the kitchen knife also apply bleed (with a chance), or only thrown/return hits for now?"="Throw only". You can now continue with the user's answers in mind.

Good question. The two files serve different purposes and were likely written at different times:

WEAPON_DESIGN.md is the comprehensive design doc — it has the full status effect system with 13 effects (Poison, Bleed, Burn, Slow, Ground, Stun, Freeze, Knockback, Disarm, Silence, Ethereal), items for each, cross-synergy items, and power fantasy archetypes. It's the "big picture" vision. Its bleed definition:

PHASE2_WEAPONS.md is the implementation-focused doc — it lists 19 weapons to implement, simplified status effect specs, and an implementation order. Its bleed definition:

The files differ in several ways:

My honest take: WEAPON_DESIGN's stacking counter version is more interesting gameplay-wise. The single-stack version from PHASE2 feels too simple — it's just "wall hit = 1 damage, done." The stacking version creates a meaningful choice: do you apply more bleed stacks or wait for wall bounces to cash them out? It also synergizes better with knockback items (🩹 Impact Trauma: "knockback wall hits also apply 1 bleed stack").

The PHASE2 simplification was probably pragmatic — "let's ship something simple first" — but since we're building it now, we might as well build the more interesting version. It's not much harder: just a counter on the ball that decrements on wall hit.

That said, there's a middle ground: start with the stacking version but keep it simple (no items/synergies yet, just the core mechanic).

AskUserQuestion

User has answered your questions: "Which bleed model do you want for the kitchen knife?"="Stacking counter (Recommended)". You can now continue with the user's answers in mind.

OK — stacking counter bleed. Thrown/return hits apply bleed, melee hits don't (for now).

Here's what I'll implement:

  1. Bleed status on ball: @bleed_stacks = 0, displayed as B [stacks]
  2. Application: Kitchen knife projectile hits apply +1 bleed stack
  3. Trigger: When a bleeding ball hits a wall, deal 1 damage and consume 1 stack
  4. Visual: Thrown/return hits colored red (damage numbers), some red indicator on bleeding balls
  5. Scaling stat: Kitchen knife weapon_ui shows bleed stacks on enemy (or just the current state)

Let me present the code for each piece. First, the ball init — adding bleed tracking:

-- In ball constructor, after other init:
@bleed_stacks = 0

Second, applying bleed on kitchen knife projectile hit (in the boomerang_sensor ball collision handler):

-- After take_damage for kitchen_knife projectile:
if projectile_object.projectile_type == 'kitchen_knife'
  ball_object.bleed_stacks += 1

Third, consuming bleed on wall hit (in the ball-wall collision handler):

-- In ball-wall collision:
if @bleed_stacks > 0
  @bleed_stacks -= 1
  @\take_damage 1

Fourth, red damage numbers for kitchen knife projectile hits.

Does this look right before I start writing?

Yes you also need to implement the status effect on top of the ball, should be B (red emoji character) followed by the number of stacks.

Let me find all the relevant code locations.

Interesting — there's recolor_blue (blue tint) and recolor_yellow (which is actually recolored to red: 223/255, 37/255, 64/255). So recolor_yellow is the red layer. Let me check if there's an actual red recolor layer, or if I need to create one:

The recolor_yellow layer already recolors to red (223, 37, 64). That's a bit confusing naming-wise, but it works. I could use that, or create a proper recolor_red layer. Let me check if recolor_yellow is used for anything:

Grep (recolor_yellow)

56:recolor_yellow = an\layer 'recolor_yellow'
272:  recolor_yellow\render!
282:  effects\draw_from recolor_yellow, an.shaders.recolor

It's defined and rendered but never actually used for drawing. So I can either:

I'll create a proper recolor_red layer to keep things clean. Now let me also look at where the ball update ends, to figure out where to draw the status text on top of the ball:

Read (E:\a327ex\emoji-ball-battles\main.yue)

  1820→      game\push @x, @y, 0, squash_x, squash_y           -- world-aligned squash (no rotation)
  1821→      game\push 0, 0, @angle, @scale*hit_scale, @scale*hit_scale  -- rotation + base scale
  1822→      game\image @image, 0, 0, nil, @ball_flashing and white!
  1823→      game\pop!
  1824→      game\pop!

OK, here's the full plan. Let me present the code for each piece:

1. Add recolor_red layer (at layer definitions, line ~56):

recolor_red = an\layer 'recolor_red'

And in the render section, render + draw_from with red color:

recolor_red\render!
-- then later:
shader_set_vec4_immediate an.shaders.recolor, "u_target_color", 223/255, 37/255, 64/255, 1
effects\draw_from recolor_red, an.shaders.recolor

2. Ball init — add @bleed_stacks = 0

3. Projectile hit — apply bleed on kitchen knife hit:

if projectile_object.projectile_type == 'kitchen_knife'
  ball_object.bleed_stacks += 1

4. Ball-wall collision — consume bleed:

if ball_object.bleed_stacks > 0
  ball_object.bleed_stacks -= 1
  ball_object\take_damage 1

5. Red damage numberstake_damage needs to know it's bleed damage. I'll add an optional args table with layer:

take_damage: (amount, source, args={}) =>
  ...
  layer = args.layer or recolor_blue
  @parent\add damage_number @x, @y - @radius - 10, amount, {duration_multiplier: 0.5, layer: layer}

6. Status display on ball — draw B [stacks] above the ball using emoji characters on recolor_red layer, only when @bleed_stacks > 0.

Does this look right?

Yes, make sure the bleed damage dealt is also red.

Let me implement everything.

1. Add recolor_red layer:

I need to make the kitchen knife hit use red damage numbers and apply bleed. The take_damage call on line 955 is shared for both boomerang and kitchen knife. I'll change it so kitchen knife passes a red layer and applies bleed after:

7. Status display on ball — draw B [stacks] above the ball:

Now I need to draw the status text on the ball. Let me find where the ball drawing ends to add this. I'll draw it using emoji characters on the recolor_red layer above the ball:

There's already an indicator layout system at line 1933-1939. That's dead code but seems like the intended place for status effects. I'll draw the bleed status above the ball using that position. Let me add it right after the debug draw, using the emoji characters on the recolor_red layer:

Let me verify that the emoji digit/letter images exist. The emoji_text class uses lowercase character names:

1945:          recolor_red\image an.images[image_name], 0, 0
3673:        image: an.images[image_name]

The emoji_text class uses an.images[image_name] where image_name is a single character. Let me check how these images get loaded — they must be loaded somewhere:

Glob (E:/a327ex/emoji-ball-battles/assets/*/b.)

Lines 107-108 load all letter images including b. So an.images['b'] and an.images['1'] etc. all exist.

Now let me verify the whole thing compiles by checking my code is clean. Let me re-read the status effect drawing:

Read (E:\a327ex\emoji-ball-battles\main.yue)

  1937→      text = "b#{@bleed_stacks}"
  1938→      total_w = #text*10

  1942→        image_name = char
  1943→        if an.images[image_name]
  1944→          recolor_red\push start_x + (i - 1)*10 + 5, status_y, 0, status_scale, status_scale

  1950→    indicator_gap = 5
  1951→    for child in *@children
  1952→      if child\is('indicator') and child.visible

Looks good. Here's a summary of all changes:

  1. recolor_red layer — new layer for red-colored emoji sprites, rendered and composited with red tint (223/255, 37/255, 64/255)
  2. @bleed_stacks = 0 — initialized on every ball
  3. Kitchen knife projectile hit — applies +1 bleed stack and uses recolor_red layer for damage number
  4. take_damage updated — accepts optional args.layer to override damage number color
  5. Ball-wall collision — if bleeding, consume 1 stack and deal 1 damage with red damage number
  6. Status display — draws b[stacks] in red emoji characters above the ball when bleed_stacks > 0

Hmmm, undo all these changes, bleed just doesn't feel good, really.

All bleed changes reverted. Kitchen knife is back to just the throw/return mechanics with no status effects.

Let's have it scale throw dmg and return dmg separately. Goes up by +1 when throwing/returning respectively.

Done. Summary:

Commit the code as currently is to the emoji-ball-battles repository, simple comment as "Kitchen Knife checkpoint" or similar. We'll remove the knife code after and do it again another way.

Committed as 88dea52 Kitchen Knife checkpoint. Not pushed.

Now let's make it so that the knife words by being thrown, but it doesn't come back like the boomerang, instead it hits and bounces off walls like the gun projectiles do. After 3 bounces it gets stuck on the wall like an arrow does, and the player can only regain it once it passes nearby. Let's try that.

This is a significant rework of the projectile behavior. Let me find all the kitchen knife projectile code and rewrite it.

Two changes needed:

  1. Init: Use impulse instead of set_velocity, set gravity_scale to something > 0, add restitution for bouncing
  2. Update: Stop overriding velocity every frame — let physics handle it. Only set velocity to 0 when stuck.

Now update the update loop — remove the manual velocity override, only zero it when stuck. Also update kitchen_knife_move_angle from actual velocity so the visual/collider tracks correctly:

Now I also need to update the wall hit handler. Since physics handles the bounce naturally via restitution, the math.reflect in hit() is no longer needed — Box2D does the bouncing. But we still need the bounce counter and stick logic. Let me update the hit method:

Now the knife uses physics naturally — impulse launch, gravity pulls it down, Box2D handles wall bounces via restitution (0.75), and after 3 bounces it sticks. The kitchen_knife_move_angle tracks the actual velocity direction each frame for the visual rotation.

Too fast impulse.

Done. After the first wall bounce, the knife starts spinning at 12*math.pi rad/s (~6 rotations/sec). Before the first bounce it tracks the velocity direction. The spin is seeded with the current move_angle so there's no visual jump.

Lower restitution, the visual angle of the knife when it sticks should be based on its velocity vector, and should be randomly a few ways into the wall always, such that the knife should never be visually stopped only with its tip touching the wall. The knife also shouldn't be able to deal damage to the enemy while its stuck.

Done:

No bounces, it's just throw, damage increases on hit, gets stuck. Spin on bounce still there, but there are no actual bounces. The code for making the knife stick correctly to the wall is not correct, also.

This session is being continued from a previous conversation that ran out of context. The summary below covers the earlier portion of the conversation.

Analysis: Let me go through the conversation chronologically:

  1. Session start: This is a continuation from a previous conversation. The summary provides context about earlier work: removing the saw weapon, fixing boomerang debug drawing via a new physics_get_shapes_geometry engine function, and beginning kitchen knife implementation.

  2. Kitchen knife throw behavior - initial implementation: The conversation started with the kitchen knife already having basic init, drawing, and alignment/fire methods. The assistant was asked to continue from where it left off - the kitchen knife throwing behavior had just been implemented but not tested.

  3. User's first feedback: "Knife shouldn't reflect on walls, should pierce but remove damage scaling, knife is a melee weapon so it should hit melee, the projectile may be a projectile object but will, for gameplay purposes later, be a melee hit, this doesn't change anything now. Doesn't need to code to not fire while facing walls because its raycast aligned and not based on cooldown like the boomerang."

    • Removed wall reflection
    • Removed damage scaling (+1 per throw)
    • Removed melee hit skip for kitchen knife
    • Removed kitchen_knife_damage variable and related code
    • Removed weapon_ui "THROW DMG" stat
  4. Wall stick + spin + gradual velocity: User requested: "when the knife hits a wall, it should be stopped there like an arrow, the projectile dies, but the visual stays there for some amount of time. When it comes back, either from wall or normally, it should rotated around itself, direction of rotation based on where it needs to move to reach the player. Finally, the way the velocity stops needs to be more realistic."

    • Added stuck state with duration
    • Added spin on return (cross product direction)
    • Added deceleration on outward, acceleration on return
  5. Spin too fast: User said "the spinning on return is too fast or it isn't being multiplied by dt." It was multiplied by dt, so reduced from 12 to 4 rad/s.

  6. Spin still wrong: User said "The knife may be being drawn without taking into account the spin?" Found the issue was a discontinuity - spin started at 0 but outward phase drew at move_angle. Fixed by seeding spin with move_angle when return starts.

  7. Spin still wrong again: User said "Nope, still wrong. Try to make the returning knife work exactly like the boomerang in terms of its rotation around itself, maybe?" Simplified to constant spin like boomerang: 12*math.pi rad/s, no cross product direction logic.

  8. Arrow-like wall drawing + stuck time: User said "like the arrow, should be drawn behind the wall. 0.3 -> 0.7 for stuck time." Changed stuck duration from 0.3 to 0.7, and discussed drawing behind wall.

  9. No need for stuck_knife object: User said "I don't think we need stuck knife object, we can just do it on the projectile directly." Simplified to draw on game layer when stuck instead of spawning separate object.

  10. Outward duration and lerp: User said "Let's set it to 0.5s, and increase the lerp down + up by 20%." Changed outward_duration 0.35→0.5s, decel 0.15→0.18s, accel 0.2→0.24s.

  11. Projectile should match knife size/angle: User said "The projectile that's created for the knife should match its size and angle at all times." Changed collider size from 16x6 to 28x8 (matching weapon hitbox), set collider angle each frame.

  12. Collider angle for return: User said "The angle of the projectile should also match the knife's visual angle when going, and should otherwise track the direction to the player when coming back." Changed to use @kitchen_knife_move_angle + @kitchen_knife_rotation_offset for outward, @kitchen_knife_move_angle for return.

  13. Collider angle wrong: User said "The actual shape angle is not correct and matching the knife when moving forward." Removed @kitchen_knife_rotation_offset from collider angle - it's a visual offset only. Collider just uses @kitchen_knife_move_angle.

  14. No wall effects: User said "There should be no visual effect when the kitchen knife hits the wall, other than it springing (this should be matched on weapon UI). When returning, there should be no effect at all possible with the walls, not even sound." Added kitchen knife special cases in collision handler.

  15. Bleed status effect discussion: User asked about status effects. Read WEAPON_DESIGN.md and PHASE2_WEAPONS.md. Discussed bleed mechanics. User chose stacking counter model, throw-only application.

  16. Bleed implementation: Added recolor_red layer, bleed_stacks on ball, bleed application on kitchen knife hit, bleed consumption on wall hit, red damage numbers, status display above ball.

  17. Bleed undone: User said "Undo all these changes, bleed just doesn't feel good, really." Reverted all bleed changes.

  18. Throw/return damage scaling: User said "Let's have it scale throw dmg and return dmg separately." Added kitchen_knife_throw_damage and kitchen_knife_return_damage, tracked separately.

  19. Commit: User asked to commit as "Kitchen Knife checkpoint". Committed as 88dea52.

  20. Major rework - bouncing knife: User said "let's make it so that the knife works by being thrown, but it doesn't come back like the boomerang, instead it hits and bounces off walls like the gun projectiles do. After 3 bounces it gets stuck on the wall like an arrow does, and the player can only regain it once it passes nearby."

  21. Rewrote projectile init (removed decel/accel/return/spin stuff, added bounces=3)
  22. Rewrote update (constant velocity, proximity catch, no return phase)
  23. Updated wall hit (bounce or stick)
  24. Updated drawing (no spin/return)
  25. Removed return_damage

  26. Physics-based throw: User said "It should be throw with impulse like normal projectiles and be affected by gravity." Changed to impulse-based launch with gravity_scale 0.5, restitution 0.75, removed manual velocity setting per frame.

  27. Speed too high: User said "Too fast impulse." Reduced from 400 to 20.

  28. Speed still too high: User said "Let's try 10 instead." Reduced to 10.

  29. Spin after first bounce: User said "After it bounces once it should rotate around itself fast." Added kitchen_knife_spinning flag, spin starts on first bounce, 12*pi rad/s.

  30. Multiple fixes: User said "Lower restitution, the visual angle of the knife when it sticks should be based on its velocity vector, and should be randomly a few ways into the wall always, such that the knife should never be visually stopped only with its tip touching the wall. The knife also shouldn't be able to deal damage to the enemy while its stuck."

  31. Lowered restitution to 0.4
  32. Added stuck angle/position from velocity + wall normal offset
  33. Skip damage for stuck knife

  34. Final rework - no bounces: User said "No bounces, it's just throw, damage increases on hit, gets stuck. Spin on bounce still there, but there are no actual bounces. The code for making the knife stick correctly to the wall is not correct, also."

  35. Set bounces to 0

Current state: bounces just set to 0, but the wall sticking code still needs to be fixed. The user explicitly said "The code for making the knife stick correctly to the wall is not correct, also."

The wall sticking code currently uses: @kitchen_knife_stuck_angle = math.angle(vx, vy) + @kitchen_knife_rotation_offset offset = an.random\float(4, 8) @kitchen_knife_stuck_x = @x - offset*normal_x @kitchen_knife_stuck_y = @y - offset*normal_y

The issue is likely the direction of the offset (should push INTO the wall, not away from it) and potentially the normal direction convention.

Summary: 1. Primary Request and Intent: - Continue implementing the Kitchen Knife weapon for Emoji Ball Battles - The knife went through MANY iterations of throw behavior: - Started as Isaac's Mom's Knife style (forward + return homing) - Went through deceleration/acceleration phases, wall stick + return, spinning on return - Changed to bouncing off walls like gun bullets (3 bounces then stick, catch on proximity) - Changed to physics-based (impulse + gravity instead of manual velocity) - Final design: thrown with impulse, affected by gravity, NO bounces, sticks on first wall hit, damage scales +1 per hit, spin code stays but doesn't trigger since 0 bounces - Bleed status effect was implemented then fully reverted ("bleed just doesn't feel good") - Committed checkpoint at 88dea52 before the bouncing rework - User explicitly stated wall sticking code is still not correct and needs fixing

  1. Key Technical Concepts:

    • YueScript game code compiled to Lua on Anchor engine (C + Box2D 3.1)
    • Physics-based projectile: impulse launch, gravity_scale, restitution for bouncing
    • boomerang_projectile collider tag reused for kitchen knife (same collision handling)
    • boomerang_sensor tag for ball hit detection (piercing)
    • Operator spacing: * and / no spaces, + and - with spaces
    • Layer system: game (behind walls), weapons (in front), recolor_blue/recolor_red for tinting
    • kitchen_knife_rotation_offset = -math.pi/4 is visual only (image orientation), NOT for collider
    • Wall normal direction in collision events
    • math.reflect for angle reflection off walls
    • stuck_arrow pattern: visual stays at wall position, drawn on game layer

  3. Errors and fixes:

    • Spin discontinuity: When switching from outward to return, visual jumped because spin started at 0 but outward drew at move_angle. Fixed by seeding @kitchen_knife_spin = @kitchen_knife_move_angle at transition.
    • Cross product spin direction was unstable: Using cross product to determine spin direction caused erratic behavior when knife flew straight back. User said it was still wrong. Fixed by switching to constant spin like boomerang (12*pi rad/s, no direction logic).
    • Rotation offset applied to collider: kitchen_knife_rotation_offset = -math.pi/4 is a visual correction for the image, NOT for the collider box. User explicitly said "The actual shape angle is not correct." Fixed by removing rotation_offset from collider angle.
    • Stuck knife wall code incorrect: User explicitly stated "The code for making the knife stick correctly to the wall is not correct, also." The current code uses @x - offset*normal_x which may have wrong direction, and math.angle(vx, vy) + @kitchen_knife_rotation_offset for the stuck angle. This still needs fixing.
    • Impulse too fast: Initial speed 400 was way too high for impulse-based physics. Reduced to 20, then to 10 per user feedback.
    • Stuck_knife class unnecessary: User said "I don't think we need stuck knife object, we can just do it on the projectile directly." Removed the class, draw on game layer from projectile instead.
  4. Problem Solving:

    • Kitchen knife went through many design iterations, each time simplifying
    • Bleed status effect was fully implemented then fully reverted
    • Throw/return damage was separated then return was removed
    • Bouncing behavior (3 bounces) was added then reduced to 0 bounces
    • The wall sticking code is still flagged as incorrect by the user
  5. All user messages:

    • "Knife shouldn't reflect on walls, should pierce but remove damage scaling, knife is a melee weapon so it should hit melee, the projectile may be a projectile object but will, for gameplay purposes later, be a melee hit, this doesn't change anything now.

When it comes back, either from wall or normally, it should rotated around itself, direction of rotation based on where it needs to move to reach the player. Finally, the way the velocity stops needs to be more realistic. Currently it stops moving abruptly when it reaches the apex, when it should be a gradual stop and then gradual return acceleration too."
    • "Do it as is, it all seems good. Except the 0.3s duration should be higher or lower depending on how far along the throw it was."

    • "The actual shape angle is not correct and matching the knife when moving forward, especially when it hits the wall."
    • "Perfect. Now the way we'll scale the knife is that thrown or return hits will be red colored and will apply bleed to the enemy. Read up on how we want status effects to work, there's details in a file somewhere."

    • "Commit the code as currently is to the emoji-ball-battles repository, simple comment as 'Kitchen Knife checkpoint' or similar. We'll remove the knife code after and do it again another way."
    • "Now let's make it so that the knife words by being thrown, but it doesn't come back like the boomerang, instead it hits and bounces off walls like the gun projectiles do.

  6. Pending Tasks:

    • Fix the wall sticking code for the kitchen knife (user explicitly said "The code for making the knife stick correctly to the wall is not correct, also")
    • The knife sticking visual needs to properly: use velocity-based angle, push the knife visually into the wall so it doesn't look like only the tip is touching
  7. Current Work: Just set @kitchen_knife_bounces = 0 per user's request for no bounces. The user's most recent message was: "No bounces, it's just throw, damage increases on hit, gets stuck. Spin on bounce still there, but there are no actual bounces. The code for making the knife stick correctly to the wall is not correct, also."

    The wall sticking code that needs fixing is in hit() method: yuescript @kitchen_knife_stuck = true vx, vy = @collider\get_velocity! @kitchen_knife_stuck_angle = math.angle(vx, vy) + @kitchen_knife_rotation_offset offset = an.random\float(4, 8) @kitchen_knife_stuck_x = @x - offset*normal_x @kitchen_knife_stuck_y = @y - offset*normal_y Issues: the offset direction relative to wall normal may be wrong (should push INTO the wall), and the stuck_arrow reference implementation uses a different approach (offsets along arrow's own angle direction).

  8. Optional Next Step: Fix the wall sticking code. The user said: "The code for making the knife stick correctly to the wall is not correct, also." The stuck_arrow reference implementation uses offset along the arrow's travel direction (@x + offset*math.cos(angle)) and checks if the angle needs flipping based on dot product with normal. Should adopt a similar approach for the kitchen knife: offset along velocity direction to push tip into wall, ensure the visual angle looks correct (knife pointing into wall surface).

Now I can see the problem clearly. The stuck_arrow works by:

  1. Using the collider angle (direction of travel)
  2. Flipping it if pointing away from wall (dot product check)
  3. Offsetting along the angle (into the wall) by 0-10 units

The kitchen knife code has two issues:

  1. The offset uses - offset*normal_x/y which pushes away from the wall (normal points outward), should push into the wall
  2. It doesn't do the dot-product flip check that the arrow does

Here's the fix — adopting the same approach as stuck_arrow but adapted for the kitchen knife's rotation offset (-math.pi/4 instead of arrow's 3*math.pi/4):

Read (E:\a327ex\emoji-ball-battles\main.yue)

  3433→        elseif @projectile_type == 'kitchen_knife'
  3434→          if @kitchen_knife_bounces > 0
  3435→            @kitchen_knife_bounces -= 1
  3436→            unless @kitchen_knife_spinning
  3437→              @kitchen_knife_spinning = true
  3438→              @kitchen_knife_spin = @kitchen_knife_move_angle
  3439→          else
  3440→            @kitchen_knife_stuck = true
  3441→            -- Stuck angle from velocity, offset into wall
  3442→            vx, vy = @collider\get_velocity!
  3443→            @kitchen_knife_stuck_angle = math.angle(vx, vy) + @kitchen_knife_rotation_offset
  3444→            offset = an.random\float(4, 8)
  3445→            @kitchen_knife_stuck_x = @x - offset*normal_x
  3446→            @kitchen_knife_stuck_y = @y - offset*normal_y
  3447→      when 'weapon'
  3448→        if @projectile_type != 'arrow' and @projectile_type != 'spiral'
  3449→          @bounces -= 1

  3451→            @\kill!
  3452→      when 'ball'

Now let me apply the fix. The approach mirrors stuck_arrow: use the velocity angle, flip if needed (dot product with normal), and offset along the angle direction (into the wall):

@kitchen_knife_stuck = true
vx, vy = @collider\get_velocity!
angle = math.angle(vx, vy)
-- Flip if knife points away from wall
if math.cos(angle)*normal_x + math.sin(angle)*normal_y < 0
  angle += math.pi
offset = an.random\float(4, 8)
@kitchen_knife_stuck_x = @x + offset*math.cos(angle)
@kitchen_knife_stuck_y = @y + offset*math.sin(angle)
@kitchen_knife_stuck_angle = angle + @kitchen_knife_rotation_offset

Key changes:

Does this look right?

Sure.

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Done. The knife should now stick into walls properly — offset along its travel direction (pushing it visually into the wall) with the angle flip check to ensure it always points inward.

The angle is still wrong. I can see that the hitbox is angled one way and the visual is another. Just make sure they're both the same at first, without trying to offset it inwards.

The issue is that math.angle(vx, vy) at collision time may differ from the pre-collision @kitchen_knife_move_angle, and the flip logic adds more divergence. Let me simplify — just use the last known move angle and current position, no offset:

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Now the stuck visual uses the exact same angle as the flying visual (move_angle + rotation_offset) and sits at the collision position with no offset. Should match the hitbox exactly.

Perfect, the angle is now correct. Now just offset it inwards. Offset it inwards more the more the weapon is parallel to the wall its on. So a knife thats facing almost completely right or left on the ceiling/ground should have a significantly stronger inwards offset otherwise it won't look believable, same for the sides.

The idea: use the dot product of the knife's direction with the wall normal to measure how parallel it is. When perpendicular (head-on), minimal offset. When parallel (glancing), large offset so it looks embedded.

@kitchen_knife_stuck = true
cos_a = math.cos(@kitchen_knife_move_angle)
sin_a = math.sin(@kitchen_knife_move_angle)
parallel = 1 - math.abs(cos_a*normal_x + sin_a*normal_y)
offset = 4 + 14*parallel
@kitchen_knife_stuck_x = @x + offset*normal_x
@kitchen_knife_stuck_y = @y + offset*normal_y
@kitchen_knife_stuck_angle = @kitchen_knife_move_angle + @kitchen_knife_rotation_offset

parallel is 0 when hitting head-on, 1 when glancing. Offset ranges from 4 to 18 pixels into the wall. The + normal direction matches the arrow's convention (normal points into the wall based on how stuck_arrow works).

Does this look right?

Sure, let's try it.

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Done. Give it a try — if the offset direction is backwards (pushing out instead of in), we just flip the sign on the normal.

14 may be too much.

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Dropped to 8, so offset ranges 4–12 now.

6 instead

Edit (E:\a327ex\emoji-ball-battles\main.yue)

Now 4–10 range.

OK, now let's change the behavior of the knife such that it works like this: a knife is generated every 5 seconds, this is what the cooldown bar tracks. The UI, however, tracks the number of knives currently held by the ball. Whenever a knife is recovered from a wall, if there's no knife currently it creates a new one as we do now, but if there's already a knife held by the player it adds to the total number of knives. Then the firing of knives happens like it does now, except instead of always firing 1 knife, we fire as many as we have with a delay between each. Makes sense?

Makes sense as a concept. A few design questions before I start:

AskUserQuestion

User has answered your questions: "When firing multiple knives, do they all fire in the same direction (wherever the weapon is pointing at trigger time), or does each knife re-align before firing?"="It works just like the gun, it fires wherever the ball is pointing at at that time." user notes: It works just like the gun, it fires wherever the ball is pointing at at that time., "What's the delay between each knife in a burst?"="Like the gun." user notes: Like the gun., "Does the weapon visual disappear while knives are in flight (like now), or only after the last knife is thrown?"="Disappear on last throw", "Is there a cap on how many knives you can hold, or infinite accumulation?"="No cap". You can now continue with the user's answers in mind.

Got it — fires like the gun (direction at time of each shot, gun-like delay), weapon stays until last knife thrown, no cap. Let me look at how the gun fires to match that pattern.

Now I have the full picture. Here's the plan for the multi-knife system:

1. Init (ball constructor, ~line 1519-1521):

2. Cooldown (line 1624-1628):

3. Fire (kitchen_knife_fire, ~line 2241):

4. Recovery (projectile catch, ~line 3325):

5. UI (~line 2585):

Here's the code. Starting with init:

-- Replace lines 1519-1521:
@kitchen_knife_cooldown = 5
@kitchen_knife_thrown = false
@kitchen_knife_count = 1
@kitchen_knife_firing = false
@kitchen_knife_fire_delay = 0.15
@kitchen_knife_throw_damage = 1

Cooldown setup (lines 1624-1628): yuescript elseif @weapon_type == 'kitchen_knife' @kitchen_knife_cooldown_running = true @timer\after @kitchen_knife_cooldown, 'kitchen_knife_cooldown', -> @kitchen_knife_count += 1 @kitchen_knife_cooldown_running = false @timer\when (-> @kitchen_knife_count > 0 and not @kitchen_knife_firing and @\kitchen_knife_is_aligned!), 'kitchen_knife_fire', (-> @\kitchen_knife_fire!) @cooldown_bar\activate @kitchen_knife_cooldown

Recovery (on catch): yuescript owner.kitchen_knife_count += 1 if owner.kitchen_knife_thrown owner.kitchen_knife_thrown = false -- Recreate weapon shapes hitbox_oy = owner.weapon_hitbox_offset_y or 0 owner.weapon_shape = owner.collider\add_box 'weapon', ... owner.weapon_sensor = owner.collider\add_box 'weapon_hitbox', ... -- Restart cooldown if not running unless owner.kitchen_knife_cooldown_running owner.kitchen_knife_cooldown_running = true owner.timer\after owner.kitchen_knife_cooldown, 'kitchen_knife_cooldown', -> owner.kitchen_knife_count += 1 owner.kitchen_knife_cooldown_running = false owner.cooldown_bar\activate owner.kitchen_knife_cooldown

Does this look right? One thing I'm uncertain about: the cooldown should probably always be running (generating a new knife every 5s continuously), not just once. Should it loop?

Yes, it's always generating new knives. Except it should get reset when the last knife is fired.

[Request interrupted by user]

Actually, there's a conflict here. There's the knife generation cooldown and the able to fire cooldown. How would you separate or mix them an intuitively correct way?

Good question. Here's how I'd think about it:

One cooldown, two roles. The cooldown bar only tracks knife generation. Firing has no separate cooldown — you fire whenever you have knives and are aligned.

The flow:

This means:

The cooldown bar always answers one question: "when do I get my next free knife?"

The only edge case is: what if a knife is generated mid-burst (you have 10 knives, firing takes longer than 5s)? I'd snapshot the count at burst start so newly generated knives go to the next burst, not the current one.

Does this match your intuition?

The player doesn't do anything, so there's no waiting to accumulate. This solution would also be kind of OP and fire knives too fast.

You're right — since it auto-fires, having no fire cooldown would just spam single knives every time alignment happens.

Simplest solution: the generation cooldown IS the fire cooldown. Same timer, same event. Every 5 seconds:

  1. count += 1 (generate a knife)
  2. Immediately fire all count knives in burst
  3. count = 0, cooldown restarts

Pickups just add to count, which means the next 5s volley has more knives in it. The bar always shows "time until next volley."

One timer, one bar, one event. Does that work?

Sure, let's try it.

Let me re-read the exact sections to make precise edits.

All done. The flow:

OK. It should only be ready to fire once the cooldown for the next knive generation is done. Currently it's firing regardless of that cooldown, as long as you have knives.

Right — timer\when is persistent (keeps checking every frame), so I need a ready flag to gate it, same pattern as the gun. Let me fix the cooldown setup, fire method, and last-knife handler.

Done. Converted both wav files to ogg, measured their volumes (-14.5 dB → 0.17, -14.1 dB → 0.16), added them to sound loading, and play one randomly on each knife throw with slight pitch variation.

Triple sound, I didn't hear anything.

Tripled to 0.51.

25% higher, somehow your normalization was wrong, do you know why?

0.51 * 1.25 = 0.64.

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

As for why the normalization was wrong — I'm guessing it's because these are very short percussive sounds (~0.28s). The mean_volume measurement gets skewed by the brevity; the sound is a quick spike with barely any sustained content, so the mean reads louder than it perceptually is. The normalization formula was designed around longer sounds where mean volume correlates better with perceived loudness.

Throw damage is still increasing for the knives, remove that.

Add a delay where a stuck knife can't be captured by the ball if it's been created recently, 1 second should work.

I'll add a kitchen_knife_catch_delay timer on the projectile that starts when it gets stuck. The catch check just skips if the delay hasn't elapsed yet.

Done. Stuck knives can't be caught for 1 second after sticking. Flying knives (non-stuck) are unaffected by the check.

0.5s. If the knives are fired close to the wall already, they don't need to be visually moved inwards.

For the offset scaling, I'll use the knife's velocity magnitude at impact — if it's barely moving (hit a wall right after spawn or lost most energy), less offset:

Done. Catch delay is now 0.5s. The wall offset scales by speed/10 (clamped to 1) — a knife that hits a wall right after being fired near it will have less inward offset, while one that's traveled and built up speed gets the full offset.

No, don't use the speed factor, use initial position compared to the wall. If the collider spawns already sort of colliding with the wall then further inwards pushing will look wrong. Either that, or we could prevent firing from happening when aiming at a wall and too close to it. But that would mess up the multiple fire logic. If you can figure out how to do that well, it'd be preferred.

First let me revert the speed_factor change:

The approach: track burst_remaining at burst start (= count). Each burst slot either fires (decrement count) or skips if spawn point is near a wall. After all slots are used, burst ends. Remaining knives carry over to next volley.

Two changes:

  1. Extend the raycast beyond the spawn point to catch walls that are slightly further:

  1. Remove base offset so perpendicular hits have zero inward push:

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Done. Raycast now extends 16px beyond the spawn point (44px total from ball center), and the inward offset is purely proportional to parallelness — 0 when perpendicular, up to 10 when glancing.

The push should still be applied if the hit isn't perpendicular, though... is it? It seems lesser now.

Yes, it's lesser. At 45° for example: before was 4 + 6*0.5 = 7, now is 10*0.5 = 5. Let me bump the multiplier so moderate angles get proper push:

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Now at 45° it's 14*0.5 = 7 (same as old), at fully parallel it's 14 (more than before), and perpendicular stays 0.

Sometimes it only fires 2 when it has 3 knives, I notice this happens due to it being near a wall. So it cancels the next fire in a burst, but doesn't complete it.

The problem is burst_remaining decrements on every call including skips, so a wall skip eats a burst slot without firing. The fix: only decrement burst_remaining when a knife actually fires, and add a max attempts cap to prevent infinite loops.

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Now burst_remaining only decrements on successful fire, and burst_attempts (capped at 3x the knife count) limits total tries to prevent infinite loops. Wall skips just retry on the next attempt as the ball rotates.

What does the next attempt mean? The next burst timing or next alignment?

The next burst timing — 0.15s later. After a wall skip, it schedules another kitchen_knife_fire_one call after the same fire_delay. The ball will have rotated a bit in that time, so the angle may clear the wall.

I see the issue now. The push is happening inwards towards the wall, but it should happen inwards towards the hitbox's angle. Let's try like that, if you get what I mean.

Yes — offset along the knife's travel direction instead of the wall normal, so it looks like it's embedding tip-first.

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Now the offset pushes along @kitchen_knife_move_angle (the knife's travel direction) using the already-computed cos_a/sin_a. Perpendicular hits get near-zero offset, glancing hits get pushed further along their own angle.

OK, let's just not have the parallel inwards push, just a normal random push for all knives. If the angle is too parallel to the wall, then we'll instead kill the knife immediately, except we'll kill it like knives die in super emoji invades, please check that. Also check the behavior of the knive throwing behavior there in terms of juice to see if it's doing something better than we are.

Good findings from SEI. Here's what I'd change:

Wall hit handler — parallel knives bounce off with spin + blink death, perpendicular knives stick with simple random offset: yuescript cos_a = math.cos(@kitchen_knife_move_angle) sin_a = math.sin(@kitchen_knife_move_angle) parallel = 1 - math.abs(cos_a*normal_x + sin_a*normal_y) if parallel > 0.7 -- Too parallel: spin off, blink, die (like SEI wall_dagger) @kitchen_knife_dying = true @collider\set_gravity_scale 1 @collider\set_linear_damping 2.5 @collider\apply_angular_impulse an.random\float(50*math.pi, 60*math.pi) * (an.random\bool(50) and 1 or -1) @timer\after an.random\float(0.3, 0.45), -> @timer\during_step an.random\float(0.2, 0.3), 0.05, 0.02, (-> @kitchen_knife_hidden = not @kitchen_knife_hidden), nil, -> @\kill! else -- Stick with random offset along travel direction @kitchen_knife_stuck = true @kitchen_knife_catchable = false @timer\after 0.5, -> @kitchen_knife_catchable = true offset = an.random\float(4, 8) @kitchen_knife_stuck_x = @x + offset*cos_a @kitchen_knife_stuck_y = @y + offset*sin_a @kitchen_knife_stuck_angle = @kitchen_knife_move_angle + @kitchen_knife_rotation_offset

Drawing — dying knives drawn on game layer with physics angle, hidden when blinking.

Update — dying knives skip stuck logic and catch proximity. Let physics drive position/angle.

Juice from SEI — the main thing we're missing is a hit_circle burst effect at the throw point. We already have spring pull. Worth adding?

Does this look right?

Yes.

4. Drawing — dying knives on game layer with physics angle, skip when hidden:

Edit (E:\a327ex\emoji-ball-battles\main.yue)

5. Wall hit handler — parallel check, dying vs sticking:

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Done. Summary of changes:

Print the parallel value for each knife stuck, make the inwards push higher than it is now for all other pushes. What is it now?

Current offset is an.random\float(4, 8) — so 4-8 pixels along the travel direction.

Edit (E:\a327ex\emoji-ball-battles\main.yue)

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Doubled the range to 8-14. The print will show the parallel value (0 = perfectly perpendicular, up to 0.7 threshold) for each stuck knife.

Value is not showing?

The print is only in the stick branch — if all hits have parallel > 0.7, they go to the dying branch and the print never runs. Let me add it to both paths:

The other print calls are in file generation functions, not runtime game code. print probably goes to stdout which isn't visible when the game window is running. Let me use the game's own text rendering instead - the emoji_text effect that floats above objects:

Now it'll show the parallel value as floating text at the knife's wall hit location.

Still not, if it wasn't printing to the console if won't show up like this.

All knives will now take the dying branch (spin off, blink, die).

The impulse on the dying knife is way too strong, should be like 10x less. Was that the impulse on the super emoji invaders project?

Yes, those were the SEI values (50-60*pi), but SEI uses Love2D's Box2D with a pixel-to-meter ratio which changes the scale. Let me reduce 10x:

Angular damping set to 7.5 (3x the linear damping), angular impulse to 25-30pi (half the original 50-60pi).

Is the knive's hitbox angle being set directly on update? Because the angular impulse seemingly has no effect. If it's being changed manually, that needs to stop while the knife is dying.

The kitchen knife guard is there, but when @kitchen_knife_dying is true, it falls through to the elseif branch which sets the angle from velocity anyway. Need to skip both:

That was the bug — dying knives fell through to the generic elseif which also sets the angle from velocity, overriding the angular impulse. Now the if catches all kitchen knives, and only non-dying ones get their angle set manually.

Set 100 damping.

Swapped — linear damping 100, angular damping back to 7.5.

The shape should become a ghost once it's dying, such that it can't affect or be affected by anything else collision-wise either physically or sensorially.

Destroying the shape removes all collision geometry — no physical or sensor interactions. The body still exists so angular impulse/damping and gravity still work for the visual spin + fall.

It's easier yet to instead kill the object immediately and create a visual-only dying_knife object that does exactly what we want.

Good call — much cleaner. Let me find where stuck_arrow is defined and add dying_knife nearby.

Done. Now the parallel hit just spawns a dying_knife visual object and kills the projectile immediately. All kitchen_knife_dying state is gone from the projectile — much cleaner. The dying_knife handles its own spin, gravity, damping, and blink-out independently.

The dying knife object should be drawn such that it's visible in front of walls.

math.lerp_dt is the frame-rate independent damping function. For damping velocity toward 0, I can use math.lerp_dt(p, t, dt, value, 0) where p is the fraction covered in t seconds.

These values can be tuned — the first param controls how much, the second controls how fast.

A new knife is not being created once the cooldown for it is done if the ball has zero knives. It's just appearing directly only once the next alignment happens.

The issue is that when the cooldown generates a new knife while kitchen_knife_thrown is true, the weapon shapes aren't being recreated. Let me fix both cooldown callbacks.

Both callbacks need to recreate weapon shapes if thrown. Let me extract the shape recreation logic into a helper to avoid duplication. Actually, it's already done in the catch code — let me just inline it in both callbacks:

Done. Knife flash shortened to 0.05s (from 0.1s), and a small camera shake (intensity 2, duration 0.08s) plays when picking up a knife from the wall.

No, the player itself should shake. Child shake object, then have the value from it affect the player's drawing only. 4, 0.1 values.

Now I understand the shake API. get_transform returns {x, y, rotation, zoom} offsets. I need to:

  1. Add a shake child to the ball
  2. Use shake\shake 4, 0.1 on knife pickup
  3. Apply the shake's transform offsets to the ball's drawing

Now I see the ball drawing. The ball uses @x, @y for positioning. I need to add a shake child and offset the drawing. Let me add the shake to the ball init and apply its offset:

I'll compute the shake offset once before drawing and add it to @x, @y in the drawing code. The cleanest way is to compute a local sx, sy offset from the shake:

Done. Pushes the ball visually 4px in the opposite direction of the throw with frequency 5 and bounce 0.5.

What do frequency and bounce mean exactly?

From the shake code, push applies a spring impulse:

push: (angle, amount, frequency, bounce) =>
  @spring\pull 'x', math.cos(angle) * amount, frequency, bounce
  @spring\pull 'y', math.sin(angle) * amount, frequency, bounce

It decomposes into X/Y spring pulls. So frequency and bounce are the spring parameters:

So push @angle + math.pi, 4, 5, 0.5 means: kick 4px backward, oscillate at frequency 5, with moderate bounciness.

10, 3, 0.5

Remove the shake when picking up knife, just spring the ball exaggerated.

This session is being continued from a previous conversation that ran out of context. The summary below covers the earlier portion of the conversation.

Analysis: Let me go through the conversation chronologically:

  1. Session start: This is a continuation from a previous conversation. The context summary explains the kitchen knife weapon went through many iterations. The last state was: bounces set to 0, wall sticking code flagged as incorrect.

  2. Wall sticking fix: I found the stuck_arrow reference implementation and compared it to the kitchen knife's broken wall sticking code. The issues were: offset direction using -offset*normal_x (wrong direction) and no dot-product flip check. I proposed adopting the arrow's approach (offset along travel direction, flip check). User approved, I applied the fix.

  3. Angle mismatch: User said "The angle is still wrong. I can see that the hitbox is angled one way and the visual is another." I simplified to just use @kitchen_knife_move_angle + @kitchen_knife_rotation_offset for the stuck angle and @x, @y for position (no offset), matching the flying visual exactly.

  4. Inward offset based on parallelness: User wanted offset inward, scaled by how parallel the knife is to the wall. I added a dot product calculation for parallelness and offset with + offset*normal_x/y. Values went through several iterations: 14→8→6 for the parallel multiplier, base offset of 4.

  5. Multi-knife system: Major rework. User wanted: knife generated every 5s (cooldown bar tracks this), UI shows knife count, picking up stuck knives adds to count, fire all held knives with delay. After Q&A: fire direction like gun (wherever pointing at time), delay like gun, weapon stays until last thrown, no cap.

  6. Cooldown/fire coupling: User pointed out auto-firing shouldn't happen without cooldown gate. Went through several design iterations. Final design: generation cooldown IS the fire cooldown. Every 5s: count += 1, fire all knives, cooldown restarts. Used kitchen_knife_ready flag pattern (like gun).

  7. Sound effects for knife throw: Converted "Throwing Knife (Thrown) 3.wav" and "4.wav" to ogg, normalized them. Initial normalization was too quiet (0.17), tripled to 0.51, then +25% to 0.64. User noted normalization was wrong - likely because short percussive sounds have misleading mean volume.

  8. Removed throw damage scaling: Removed the +1 damage increment on kitchen knife hits.

  9. Stuck knife catch delay: Added 0.5s delay before stuck knives can be picked up (was 1s initially, reduced to 0.5).

  10. Wall proximity fire prevention: Added raycast check before spawning knife - if spawn point too close to wall, skip. Extended raycast range by +16px. Fixed burst logic: burst_remaining only decrements on successful fire, burst_attempts (3x count) limits total tries.

  11. Wall sticking offset rework: User said "don't use speed factor, use initial position compared to wall" then preferred preventing firing near walls. Removed speed_factor approach.

  12. Parallel wall hit → dying knife: User wanted: no parallel-based push, simple random offset for sticking. If too parallel (>0.7), kill the knife like in Super Emoji Invaders. I researched SEI's wall_dagger implementation.

  13. Dying knife as separate visual object: User said "It's easier yet to instead kill the object immediately and create a visual-only dying_knife object." Created dying_knife class with spin, gravity, damping, blink-out death. Removed all kitchen_knife_dying state from projectile code.

  14. Various dying_knife adjustments:

    • Draw on weapons layer (front of walls)
    • Use math.lerp_dt for frame-rate independent damping
    • Angular impulse values: SEI's 50-60π was too strong, went to 25-30π (half original)
    • Linear damping 100, angular damping 7.5
    • Fixed collider angle override bug (dying knife fell through to generic elseif)
  15. Parallel threshold: Set to 0 for testing, then back to 0.7.

  16. Sounds:

    • dagger_wall plays when dying knife spawns
    • Tried knife_stick (Spear throw 1.wav) for wall stick, went back to wood_heavy at 80% volume
    • knife_throw_1 on pickup, knife_throw_2 on throw
  17. Weapon shape recreation on cooldown: Fixed bug where weapon shapes weren't recreated when cooldown generated a new knife while kitchen_knife_thrown was true.

  18. Flash duration: Made projectile class support numeric flash_on_spawn for custom duration. Kitchen knife uses 0.05s.

  19. Ball shake on pickup: Added ball_shake child shake object to ball. Applied shake offsets to all ball+weapon drawing. Tried camera shake (rejected), then ball_shake\shake with various values (4,0.1 → 10,1 → 4,0.3).

  20. Directional spring push on fire: Added ball_shake\push in opposite direction of firing. Tried 4,5,0.5 then 10,3,0.5. User said remove it.

  21. Current: User said "Remove the shake when picking up knife, just spring the ball exaggerated." - this is the pending task.

Summary: 1. Primary Request and Intent: - Continue implementing the Kitchen Knife weapon for Emoji Ball Battles - Fix wall sticking code (angle and position offset) - Implement multi-knife system: generate knife every 5s, accumulate count, fire all in burst like the gun - Add sound effects for throwing, sticking, and picking up knives - Implement parallel wall hit detection: perpendicular hits stick, parallel hits spawn a dying_knife visual that spins/blinks/dies (like SEI's wall_dagger) - Add visual feedback: ball shake on knife pickup, shorter flash on throw, spring on fire - Various tuning of values throughout

  1. Key Technical Concepts:

    • YueScript compiled to Lua on Anchor engine (C + Box2D 3.1)
    • timer\when is persistent (checks every frame), requires a ready flag pattern like the gun
    • math.lerp_dt(p, t, dt, value, target) for frame-rate independent damping
    • shake\push(angle, amount, frequency, bounce) for directional spring impulse on shake objects
    • shake\shake(amplitude, duration) for random jitter shake
    • shake\get_transform! returns {x, y, rotation, zoom} offsets
    • Sound normalization: volume = 0.5 * 10^((-24 - mean_dB) / 20), but short percussive sounds need ~3x correction
    • Operator spacing: * and / no spaces, + and - with spaces
    • Collision normals: + offset*normal pushes into the wall (based on stuck_arrow reference)
    • flash_on_spawn can be boolean (0.1s default) or numeric (custom duration)

      • knife_throw_1.ogg (from "Throwing Knife (Thrown) 3.wav")

  3. Errors and fixes:

    • Wall offset direction wrong: Original code used @x - offset*normal_x which pushed away from wall. Fixed by using + offset*normal_x (normal points into wall based on stuck_arrow reference).
    • Angle mismatch between hitbox and visual: Stuck angle computed from velocity at collision time differed from pre-collision move_angle. Fixed by using @kitchen_knife_move_angle + @kitchen_knife_rotation_offset directly.
    • timer\when is persistent: Removed kitchen_knife_ready flag thinking timer\when inside cooldown callback would work, but timer\when checks every frame. User reported knives firing without waiting for cooldown. Fixed by restoring the ready flag pattern (same as gun).
    • Burst skipping wall-adjacent knives: burst_remaining decremented on every call including wall skips, causing fewer knives fired. Fixed by only decrementing burst_remaining on successful fire, with separate burst_attempts counter (3x count) to prevent infinite loops.
    • Sound normalization too quiet: Formula gave 0.17 for knife throw sounds but they were inaudible. Short percussive sounds have misleading mean volume. Tripled to 0.51, then +25% to 0.64.
    • nil statement invalid in YueScript: Used nil -- comment as empty branch body, caused compilation error. Fixed by restructuring to unless @kitchen_knife_dying wrapping the other branches.
    • print not showing: File wasn't compiling due to the nil error above, so prints never ran. Once compilation fixed, print works to console.
    • Dying knife collider angle overridden: The if @projectile_type == 'kitchen_knife' / elseif chain meant dying knives fell through to generic angle-from-velocity setting. Fixed by nesting unless @kitchen_knife_dying inside the kitchen_knife branch.
    • Angular impulse too strong: SEI values (50-60π) were for Love2D's Box2D with pixel-to-meter ratio. Reduced to 25-30π (half original).
    • Weapon shapes not recreated on cooldown: When cooldown generated a new knife while kitchen_knife_thrown was true, weapon stayed invisible. Added shape recreation logic to both cooldown callbacks.
    • Naive damping not frame-rate independent: Used velocity *= (1 - damping*dt) which is frame-rate dependent. User requested using proper math damping functions. Changed to math.lerp_dt.
  4. Problem Solving:

    • Wall sticking solved by adopting stuck_arrow's approach (offset along travel direction, dot-product flip check)
    • Multi-knife system solved by coupling generation and fire into one cooldown event with ready flag pattern
    • Parallel wall hits solved by spawning separate dying_knife visual object (much cleaner than modifying projectile state)
    • Ball shake solved by adding shake child object with get_transform offsets applied to drawing
  5. All user messages:

    • "Sure." (approving wall stick fix)
    • "The angle is still wrong. I can see that the hitbox is angled one way and the visual is another. Just make sure they're both the same at first, without trying to offset it inwards."
    • "Sure, let's try it." (approving angle-only fix)
    • "14 may be too much."
    • "6 instead"
    • "OK, now let's change the behavior of the knife such that it works like this: a knife is generated every 5 seconds, this is what the cooldown bar tracks. The UI, however, tracks the number of knives currently held by the ball. Whenever a knife is recovered from a wall, if there's no knife currently it creates a new one as we do now, but if there's already a knife held by the player it adds to the total number of knives. Then the firing of knives happens like it does now, except instead of always firing 1 knife, we fire as many as we have with a delay between each. Makes sense?"
    • (Multi-select answers: fire direction "like the gun", delay "like the gun", weapon visual "disappear on last throw", knife cap "no cap")
    • "Yes, it's always generating new knives. Except it should get reset when the last knife is fired. Actually, there's a conflict here. There's the knife generation cooldown and the able to fire cooldown. How would you separate or mix them an intuitively correct way?"
    • "The player doesn't do anything, so there's no waiting to accumulate. This solution would also be kind of OP and fire knives too fast."
    • "Sure, let's try it." (approving single-cooldown design)
    • "OK. It should only be ready to fire once the cooldown for the next knive generation is done. Currently it's firing regardless of that cooldown, as long as you have knives."
    • "Convert throwning knife 3 and 4 wav to ogg, normalize them according to the comments in sound loading, play one randomly whenever a knife is fired."
    • "Triple sound, I didn't hear anything."
    • "25% higher, somehow your normalization was wrong, do you know why?"
    • "Throw damage is still increasing for the knives, remove that."
    • "Add a delay where a stuck knife can't be captured by the ball if it's been created recently, 1 second should work."
    • "0.5s. If the knives are fired close to the wall already, they don't need to be visually moved inwards."
    • "No, don't use the speed factor, use initial position compared to the wall. If the collider spawns already sort of colliding with the wall then further inwards pushing will look wrong. Either that, or we could prevent firing from happening when aiming at a wall and too close to it. But that would mess up the multiple fire logic. If you can figure out how to do that well, it'd be preferred."
    • "Sure, let's try it." (approving wall proximity fire prevention)
    • "Let's increase the wall prevention range, and let's make it so that when projectiles are more perpendicular there's no inwards pushing at all."
    • "The push should still be applied if the hit isn't perpendicular, though... is it? It seems lesser now."
    • "Sometimes it only fires 2 when it has 3 knives, I notice this happens due to it being near a wall. So it cancels the next fire in a burst, but doesn't complete it."
    • "What does the next attempt mean? The next burst timing or next alignment?"
    • "I see the issue now. The push is happening inwards towards the wall, but it should happen inwards towards the hitbox's angle. Let's try like that, if you get what I mean."
    • "OK, let's just not have the parallel inwards push, just a normal random push for all knives. If the angle is too parallel to the wall, then we'll instead kill the knife immediately, except we'll kill it like knives die in super emoji invades, please check that. Also check the behavior of the knive throwing behavior there in terms of juice to see if it's doing something better than we are."
    • "Yes." (approving dying knife approach)
    • "The dying knife object should be drawn such that it's visible in front of walls."
    • "Any damping used should use the appropriate math damping functions we have that take into account multiple frames properly."
    • "A new knife is not being created once the cooldown for it is done if the ball has zero knives. It's just appearing directly only once the next alignment happens."
    • "Set the parallel threshold back to 0.7"
    • "Play dagger_wall when the dying knife is spawned"
    • "Reduce from 8, 14 to 8, 10."
    • "Let's play the same sound that plays when a boomerang hits a wall, when a knife gets stuck on a wall."
    • "Let's try Spear throw 1.wav instead of the wood heavy sounds. Convert, normalize, etc."
    • "I added it."
    • "Go back to wood sounds, but make them 20% lower."
    • "Thrown knives should flash for a shorter amount of time, player should shake (not spring) when getting a knife from the wall."
    • "No, the player itself should shake. Child shake object, then have the value from it affect the player's drawing only. 4, 0.1 values."

    • "Let's make all knives hit the parallel branch now to test it."

    • "We can simply the second operand by using random sign"
    • "The angular damping needs to be like 3x, the angular impulse should be half what it was originally."
    • "Is the knive's hitbox angle being set directly on update? Because the angular impulse seemingly has no effect. If it's being changed manually, that needs to stop while the knife is dying."
    • "Set 100 damping."
    • "Oh, that's why, I meant linear damping."
    • "The shape should become a ghost once it's dying, such that it can't affect or be affected by anything else collision-wise either physically or sensorially."

  6. Pending Tasks:

    • Remove the ball_shake on knife pickup, replace with exaggerated spring pull on the ball
  7. Current Work: The user's most recent message was: "Remove the shake when picking up knife, just spring the ball exaggerated."

    The current knife pickup code (~line 3381) is: yuescript owner.kitchen_knife_count += 1 an\sound_play 'knife_throw_1', 0.64, an.random\float(0.95, 1.05) owner.ball_shake\shake 4, 0.3 owner.spring\pull 'weapon', 0.4, 3, 0.5

    Need to remove owner.ball_shake\shake 4, 0.3 and replace with an exaggerated spring pull on the ball (likely owner.spring\pull 'hit', ... with larger values).

  8. Optional Next Step: Remove owner.ball_shake\shake 4, 0.3 from the knife pickup code and replace it with an exaggerated owner.spring\pull 'hit' (or similar ball spring) with amplified values. The user said: "Remove the shake when picking up knife, just spring the ball exaggerated."

If you need specific details from before compaction (like exact code snippets, error messages, or content you generated), read the full transcript at: C:\Users\adn.claude\projects\E--a327ex\90052d62-60a3-4899-bfa8-ee6cbbd4e170.jsonl Please continue the conversation from where we left off without asking the user any further questions. Continue with the last task that you were asked to work on.

Let me read the current knife pickup code to make the change.

Grep (owner.ball_shake\shake)

3380-        if d < 20 and (not @kitchen_knife_stuck or @kitchen_knife_catchable)
3381-          owner.kitchen_knife_count += 1
3382-          an\sound_play 'knife_throw_1', 0.64, an.random\float(0.95, 1.05)
3383:          owner.ball_shake\shake 4, 0.3
3384-          owner.spring\pull 'weapon', 0.4, 3, 0.5
3385-          if owner.kitchen_knife_thrown
3386-            owner.kitchen_knife_thrown = false

Here's what I'll change — remove the ball_shake\shake line and make the spring pull more exaggerated. Currently the weapon spring is 0.4, 3, 0.5. I'll replace the shake with a hit spring pull with bigger values:

-- Before:
owner.ball_shake\shake 4, 0.3
owner.spring\pull 'weapon', 0.4, 3, 0.5

-- After:
owner.spring\pull 'hit', 0.6, 3, 0.5
owner.spring\pull 'weapon', 0.4, 3, 0.5

The hit spring affects the ball's scale (the ball itself), while weapon affects the weapon visual. Does this look right, or did you want different values for the exaggerated spring?

Actually, the summary says to proceed without asking — let me just do it. I'll use 0.6, 3, 0.5 for the hit spring as a starting point.

The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.

Done. Replaced owner.ball_shake\shake 4, 0.3 with owner.spring\pull 'hit', 0.6, 3, 0.5 — this springs the ball's scale instead of shaking its position. The hit spring is what the ball already uses for hit feedback, so it'll give that satisfying pop effect on knife pickup. You can tune the 0.6 amplitude up or down from there.

Done. The enemy ball now defaults to 'sword' instead of 'boomerang'.

Melee weapons should be able to parry the knife projectile in the same way that gun projectiles can be parried by them. In this case, the knife should physically affect the melee weapon, but then it should die and dying_knife visual should be spawned, its initial velocity based on how the melee weapon hit it.

Let me understand how the existing parry system works for gun projectiles.

Now let me also check the kitchen knife sensor events to see how the knife currently interacts with weapons/balls.

Now let me check how the kitchen knife projectile's collider is tagged — it uses 'boomerang_projectile' tag, so it already collides with 'weapon' via the 'projectile', 'weapon' collision... wait, let me check.

Grep (physics_collision.projectile.weapon|physics_collision.weapon.projectile)

251:an\physics_collision 'projectile', 'weapon'

Grep (physics_collision.boomerang_projectile|physics_sensor.boomerang_projectile)

259:an\physics_collision 'boomerang_projectile', 'wall'

So the kitchen knife uses 'boomerang_projectile' tag, which only has a collision registered with 'wall', not with 'weapon'. The regular 'projectile' tag is what collides with 'weapon' for the parry system.

I need to add a collision between 'boomerang_projectile' and 'weapon', then handle it in the parry section. Let me also check the dying_knife spawn code from the wall hit handler to reuse the same pattern.

Now I see the when 'weapon' handler at line 3515. Currently it only handles bullet-like projectiles (bounces). I need to:

  1. Add an\physics_collision 'boomerang_projectile', 'weapon' (line ~259)
  2. Handle 'boomerang_projectile' + 'weapon' collisions in the arena update — similar to the existing 'projectile', 'weapon' parry handler but for kitchen knife specifically: spawn dying_knife, kill projectile, apply weapon effects

Let me check if there's already a handler for boomerang_projectile + weapon or if I need to add a new collision event loop:

  1084→      attacker.weapon_ui\landed_hit! if attacker.weapon_ui
  1085→
  1086→      -- headless: log melee hit
  1087→      @headless_events[] = {step: @headless_step_count, type: 'hit', attacker: attacker.team, defender: defender.team, damage: damage, weapon: attacker.weapon_type, hit_type: 'melee'}

  1094→        attacker.thrust_hit_this_thrust = true

Good. Now I have a clear picture. Here's my plan:

  1. Add physics collision 'boomerang_projectile', 'weapon' at line 259
  2. Add a new collision handler for 'boomerang_projectile', 'weapon' events that:
    • Skips same team
    • Skips if knife is stuck
    • Spawns dying_knife with velocity based on the weapon's hit (reflected off weapon normal)
    • Kills the knife projectile
    • Applies weapon effects (flash, spring, angular velocity dampening by weapon weight)
    • Plays parry sound
    • Logs headless parry event

Here's the code I'd add. First, the collision registration:

an\physics_collision 'boomerang_projectile', 'weapon'

Then the handler (placed after the existing 'boomerang_projectile', 'wall' handler around line 1028). Does this approach look right?

Good. I'll add the handler right after line 1028 (after the boomerang_projectile wall handler). Here's what I propose:

    -- Kitchen knife projectile-weapon collision: parry (spawn dying_knife)
    for event in *an\collision_begin_events 'boomerang_projectile', 'weapon'
      projectile_object = event.a
      ball_object = event.b

      continue if ball_object.team == projectile_object.team
      continue unless projectile_object.projectile_type == 'kitchen_knife'
      continue if projectile_object.kitchen_knife_stuck

      -- Reflect knife velocity off weapon surface
      vx, vy = projectile_object.collider\get_velocity!
      v = math.length(vx, vy)
      nx = -math.sin(ball_object.angle)
      ny = math.cos(ball_object.angle)
      dot = vx*nx + vy*ny
      reflect_vx = vx - 2*dot*nx
      reflect_vy = vy - 2*dot*ny
      reflect_len = math.length(reflect_vx, reflect_vy)
      if reflect_len > 0
        reflect_vx = reflect_vx/reflect_len*v*0.3
        reflect_vy = reflect_vy/reflect_len*v*0.3

      -- Spawn dying knife
      an\sound_play 'dagger_wall', 0.5, an.random\float(0.95, 1.05)
      @effects\add dying_knife projectile_object.x, projectile_object.y,

        scale: projectile_object.kitchen_knife_scale
        rotation_offset: projectile_object.kitchen_knife_rotation_offset
        vx: reflect_vx
        vy: reflect_vy
      projectile_object\kill!

      -- Weapon feedback (flash, spring, weight-based angular dampening)
      ball_object\flash_weapon!
      ball_object.spring\pull 'weapon', 0.35, 3, 0.5
      av = ball_object.collider\get_angular_velocity!
      change = av - ball_object.last_angular_velocity
      scaled_change = change / ball_object.weapon_weight^2
      av = ball_object.last_angular_velocity + scaled_change
      ball_object.collider\set_angular_velocity av

      -- headless: log parry
      owner = if projectile_object.team == 'player' then @player_ball else @enemy_ball
      @headless_events[] = {step: @headless_step_count, type: 'parry', ball_a: ball_object.team, ball_b: owner.team, weapon_a: ball_object.weapon_type, weapon_b: owner.weapon_type}

      an\sound_play "weapon_projectile_#{an.random\int(1, 2)}", 1.0, an.random\float(0.95, 1.05)

Does this look right?

Sure, let's try it.

Done. Added:

  1. an\physics_collision 'boomerang_projectile', 'weapon' — registers the collision pair
  2. Handler that on kitchen knife hitting an enemy weapon: reflects velocity off the weapon surface, spawns a dying_knife with 30% of reflected speed, kills the projectile, applies weapon feedback (flash, spring, weight-based angular dampening), logs the parry, and plays the parry sound

When a knife is stuck, it shouldn't physically collide with melee weapons.

Let me check how the knife's shapes are set up and what happens when it sticks.

The knife has a physical boomerang_projectile shape (line 3322) and a sensor boomerang_sensor shape (line 3335). The simplest fix: when the knife sticks to a wall, destroy the physical shape. The sensor remains for ball pickup detection, and nothing can physically collide with the stuck knife anymore.

Let me find the stuck code:

I'll destroy the physical shape when the knife sticks, so it can't physically collide with anything anymore (the sensor shape remains for ball pickup):

Done. When the knife sticks to a wall, @shape (the physical boomerang_projectile box) is destroyed. The @ball_sensor (the boomerang_sensor shape) remains intact for ball pickup detection, but the knife no longer has any physical collision shape for weapons to hit.

Nope, this isn't working.

The issue is likely @shape — on the projectile object that refers to nothing. The collider's physical shape handle is stored as @collider.shape. Let me fix it:

That should do it — @collider.shape is where the collider class stores the physical shape handle.

Perfect. I believe this finishes it, thank you.

Great, glad it's all working! To recap what we did this session:
