EBB Juice Archeology and Plan

The user wants me to analyze three emoji game projects in the reference/ folder to document all visual effects/juice used in them. Before starting, I should ask clarifying questions to make sure I understand the task correctly.

Let me think about what questions I need to ask:

1. Output format - should this be a markdown file in reference/? What structure do they want?
2. Level of detail - how granular should I be? Should I include code snippets for each effect?
3. The three folders - I should verify what they're called exactly
4. Translation to Anchor - should I include full working code or pseudocode?
5. Categorization - how should I organize the effects? By type (particles, screen shake, flashes)? By game? By when they trigger?

Let me formulate good questions using AskUserQuestion.

User has answered your questions: "Where should I output the documentation? A single markdown file in reference/, or multiple files organized somehow?"="Single file", "How should I organize/categorize the effects within the documentation?"="It honestly doesn't matter to me, pick whatever you want or don't organize at all.", "For the Anchor translation of each effect, what level of code detail do you want?"="Full working code", "Should I include gameplay-adjacent effects that are borderline visual (like knockback, slow-motion, camera zoom) or strictly visual-only effects?"="Include borderline". You can now continue with the user's answers in mind.

Good, I have my answers:

1. Single markdown file in reference/
2. Organization is up to me
3. Full working code for Anchor translations
4. Include borderline effects like knockback, hitstop, slow-mo, camera effects

Before I start, let me verify what folders exist in reference/ and also read the framework API so I understand how to translate effects properly. I should also let the user give final instructions before I begin.

Actually, the user said "Once you have no more questions, give me a turn before starting the work so I can give you your final instructions." So I should summarize what I understand and wait for their go-ahead.

The user wants me to be very careful and thorough. Let me start by:

1. First reading the Framework API docs to understand the current Anchor API
2. Then exploring each of the three game folders to understand their structure
3. Going through each game systematically to document all effects

Let me start by reading the framework documentation.

I have a good understanding of the folder structure now. Let me create a todo list for this task and start reading through each game systematically.

The three games are:

1. **emojunky-one** - Lua files: main.lua, entities.lua, decorations.lua, particles.lua, ui.lua, etc. This is the oldest and uses LÖVE framework directly.
2. **emoji-merge-main** - Uses proto-Anchor (has anchor/ folder), main.lua is 84KB
3. **super emoji box** - Also uses proto-Anchor (has lun/ folder), main.lua is ~45KB

Let me create a todo list and start reading the files.

- [in_progress] Read and understand emojunky-one game effects

- [pending] Read and understand emoji-merge-main game effects
- [pending] Read and understand super emoji box game effects
- [pending] Compile all effects into single documentation file with Anchor translations

Now let me start reading the emojunky-one files. I'll start with the main files that likely contain effects: particles.lua, decorations.lua, entities.lua, and main.lua.

This is great, I'm seeing a lot of particle effects in emojunky. Let me continue reading the rest of the particles.lua file, and then move to decorations.lua and entities.lua.

This is interesting - this shows plant decoration effects that respond to wind forces. Let me continue reading the rest of decorations.lua and then move to the entities.lua file which is likely the largest.

File content (26720 tokens) exceeds maximum allowed tokens (25000). Please use offset and limit parameters to read specific portions of the file, or use the GrepTool to search for specific content.

The entities.lua file is very large. I need to read it in chunks.

This is very rich with effects! Let me continue reading more of the entities.lua file to capture all the effects. I can see springs, particles, tweens, and various weapon effects.

I've now read through all three games and the Anchor Framework API. I have a comprehensive understanding of all the effects used. Now I need to compile this into a single documentation file with:

1. All effects organized by type
2. Each effect's description - when it happens, what it does
3. Full working Anchor code for each effect

Let me update the todo list and start writing the documentation file.

- [completed] Read and understand emojunky-one game effects

- [completed] Read and understand emoji-merge-main game effects
- [completed] Read and understand super emoji box game effects
- [in_progress] Compile all effects into single documentation file with Anchor translations

Looking at the summary, I was in the middle of compiling all the effects documentation into a single markdown file. I had read through all three reference game codebases (emojunky-one, emoji-merge-main, super emoji box) and was about to write the comprehensive documentation file.

Let me continue with that task. I need to create a thorough documentation file that:

1. Documents every visual effect from all three games
2. Describes when each effect triggers
3. Provides all parameters (spring values, durations, etc.)
4. Translates each effect to working Anchor YueScript code

I should re-read the key files to make sure I have all the details fresh, then write the documentation file. Since the context was compacted, I may need to re-read some of the reference files to ensure accuracy.

Let me start by re-reading the key files from each game to refresh my memory of the specific effect implementations, then compile the documentation.

I have a good understanding of the effects now. Let me now write the comprehensive documentation file.

File created successfully at: E:\a327ex\emoji-ball-battles\reference\emoji_effects_documentation.md

Now let me update the todo list to mark the task as completed.

- [completed] Read and understand emojunky-one game effects

- [completed] Read and understand emoji-merge-main game effects
- [completed] Read and understand super emoji box game effects
- [completed] Compile all effects into single documentation file with Anchor translations

The documentation is complete. Let me provide a summary to the user.

The user wants me to read the engine API and compare it against the effects documentation to identify what functions are missing - both at the engine level (C code) and framework level (YueScript wrappers).

Let me read the engine API documentation first, then cross-reference with what effects need.

Now I need to analyze what the effects documentation requires vs what the engine and framework currently provide. Let me check the framework source files to see what's actually implemented.

Now I have a good understanding of what exists. Let me analyze the gaps between what the effects documentation requires and what's currently available.

**Current Framework:**

- Spring: ✅ Has add, pull, set_target, at_rest - fully implemented
- Shake: ✅ Has trauma, push, shake, sine, square, handcam - fully implemented
- Layer: ✅ Has rectangle, circle, image, text, push, pop, blend modes, shaders
- Timer: Need to check but likely has tween, after, every, etc.

**What the effects need:**

1. **Flash Effect** - The layer\image function already has a `flash` parameter! This is good. But looking at the code more carefully:
   - `layer\image image, x, y, color, flash` - takes a flash color parameter
   - The reference games used a "combine" shader to flash things white

2. **Animation System** - The reference games had frame-based animations (hit1 animation in super emoji box). The engine API shows `lun:animation_frames('hit1', 'hit1', 96, 48)` which creates animation frames. I need to check if this exists in Anchor.

3. **Slow Motion / Time Scale** - The reference games scaled dt for slow-mo effects. Need to check if there's a time scale function. The engine API mentions `audio_set_master_pitch` for audio slow-mo but not game time scale.

4. **Math utilities** - Need math.angle for calculating angles from normals, math.bounce for reflecting angles, math.distance, math.sign (but engine has random_sign), etc.

Let me check what's in the math extension file and timer.

Now I have a comprehensive understanding of what exists. Let me compile the analysis of what's missing.

**What the effects documentation requires vs what exists:**

## ENGINE LEVEL (C code):

**Already have:**

- layer_draw_texture with flash parameter ✅
- Perlin noise ✅
- Random functions ✅
- All physics queries ✅
- Audio functions ✅

**Missing at engine level:**

1. **Time scale** - No engine function to scale game time. Reference games used a multiplier on dt. Would need:
   - `engine_set_time_scale(scale)` 
   - `engine_get_time_scale() -> number`
   
2. **Animation system** - The reference games used frame-based animations (`lun:animation_frames`). Current engine/framework doesn't have this. Would need:
   - Animation frame registration
   - Animation state machine (current frame, play mode, callback on complete)
   - Layer drawing for animations

3. **Audio pitch for slow-mo** - The engine has `audio_set_master_pitch` but I should verify this exists for slow-mo feel.

## FRAMEWORK LEVEL (YueScript):

**Already have:**

- Spring system ✅ (full implementation)
- Shake system ✅ (trauma, push, shake, sine, square, handcam)
- Timer system ✅ (after, every, during, tween, watch, when, cooldown)
- Layer drawing with flash ✅
- Math utilities ✅ (lerp, lerp_dt, lerp_angle, clamp, remap, loop, length, sign)
- Easing functions ✅ (all of them)

**Missing at framework level:**

1. **math.angle(x, y)** or **math.angle_from_vector(x, y)** - Get angle from vector components (atan2 wrapper)
2. **math.angle_to_point(x1, y1, x2, y2)** - Get angle between two points


3. **math.distance(x1, y1, x2, y2)** - Euclidean distance between two points
4. **math.normalize(x, y)** - Normalize a vector
5. **math.bounce(angle, normal_x, normal_y)** - Reflect an angle off a surface normal (used for bouncing projectiles)
6. **math.snap(value, grid)** - Snap value to nearest grid point (used for snapping rotation back to 0)
7. **math.damping(factor, target, dt, value)** - Similar to lerp_dt but simpler interface
8. **Animation class** - Need to build out frame-based animation support with state tracking and completion callbacks

. Should handle different play modes like 'once', 'loop', and 'pingpong', manage current frame position, and allow speed adjustments. Can also trigger callbacks when reaching specific frames or finishing.

9. **HitFX pattern** - A convenience wrapper combining springs and flash effects for hit feedback, though this is more of a common pattern than a required system since the underlying components already exist separately.

10. **Plant/Wind system** - The wind physics simulation with constant, random, and moving forces is fairly specialized to this game's needs.

11. **Global time scale** - Need a way to uniformly adjust game speed that affects both timers and physics calculations.

Now I'll add the new math utilities after the existing utility functions (after `math.remap` around line 215, before the easing functions start at line 217). I'll update the header comment to include the new functions too.

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

Now I need to add the actual function implementations after `math.remap` and before the easing functions.

The game compiled and runs correctly. The math utilities have been added successfully. Let me kill the running game and provide a summary to the user.

Shell be0d5c9 is not running, so cannot be killed (status: completed)

The game compiled and ran without errors. I've successfully added the math utilities. Let me provide a summary to the user.

This is just a notification that the background task completed. I already read the output and confirmed everything works. No action needed - I've already summarized the changes for the user.

The user wants me to do a higher-level analysis of the effects, focusing on:

1. How effects are composed together (not just individual particles/springs, but the full "hit enemy" effect that uses multiple things)
2. High-level descriptions of behavior, not code
3. Specific values when possible
4. Different contexts where the same low-level effects are used differently

Before I start, let me think about what questions I might have:

1. Should this be a separate file or should I update the existing one?
2. Should I organize by game event (e.g., "enemy hit", "player lands", "projectile fires") or by effect category?
3. How detailed should the "specific values" be - exact numbers or ranges?

I think I should ask about organization, since that will significantly affect the document structure. Let me ask about that.

User has answered your questions: "Should this be a new file or should I update the existing emoji_effects_documentation.md?"="Append to existing", "How should I organize the effects?"="Doesn't matter to me". You can now continue with the user's answers in mind.

Okay, I'll append to the existing file and organize by game event since that makes the most sense for understanding "when X happens, all these effects occur together."

Let me re-read the reference game files more carefully this time, focusing on:

1. What triggers each composite effect
2. All the individual effects that happen together
3. Specific parameter values

I should go through each game systematically and look for game events like:

- Player hit/damage
- Enemy hit/damage
- Enemy death
- Player death
- Projectile fire
- Projectile impact
- Jump/land
- Dash
- Pickup/collect
- Merge (emoji-merge specific)
- Level transition
- etc.

Let me re-read the files with this lens.

The user wants me to continue with the task of creating a high-level composite effects analysis. Based on the summary, I was in the middle of gathering information from the reference game files to understand composite effects.

Let me continue by reading more of the reference files to gather complete information, then write the high-level effects section to append to the existing documentation.

I should:

1. Read more from the reference games (emoji-merge-main, super emoji box) to gather composite effect patterns
2. Write the high-level effects analysis
3. Append it to `reference/emoji_effects_documentation.md`

Let me continue reading the reference files to complete my understanding.

Now I have a good understanding of all the composite effects across the three games. Let me now write the high-level composite effects section and append it to the existing documentation. I'll organize it by game events and describe what happens when each event occurs.

Key composite effects I've identified:

**emojunky-one:**

1. **Player Hit**
   - Spring pull 0.25 (hit_spring)
   - Camera shake(4, 0.4)

   - Sound "hit1" with varying pitch (1.2-1.6)

3. **Enemy (Blob) Death**
   - Flash 0.1s
   - Spring pull 0.3

   - Sound "hit1" pitch 0.6
   - Optional: spawn Moneybag (25% chance)

4. **Enemy Cut by Scissors**
   - InfoText showing HP
   - Two EnemyDead particles (left and right halves)
   - 4 StarParticles
   - Optional Moneybag spawn

5. **Player Jump Landing**
   - Jump spring X/Y pull based on velocity
   - If velocity > 200 and not holding up:
     - Camera spring_shake based on velocity, direction pi/2
     - 2 DashParticles
     - Plant force on nearby plants (radius 75, force 75-25)
     - Grass land sound

6. **Gun Fire**
   - Spring pull 0.3 on gun, 0.1 on actor
   - Gun rotation tween (up and back)
   - BoomParticle spawns at muzzle
   - Nearby plants receive direct force
   - Camera shake(4, 0.25)
   - Shot sound plays
   - Bullet projectile spawns

7. **Stomp on Enemy**
   - 3 StarParticles around enemy
   - Enemy takes 1 damage (hit effects)
   - Player bounces (vy = -200)
   - Player jump springs pull

8. **Enemy Power Up (went off screen)**

**super emoji box:**

1. **Player Landing**
   - Jump springs (jump_x, jump_y) pulled based on velocity
   - Camera spring shake based on velocity
   - 2 DashParticles
   - Plant direct force on nearby plants
   - Sound effects (grass land + impact)
   - "just_landed_from_jump" state for 0.2s changes emoji

2. **Enemy Hit - Non-lethal**
   - Spring pull 0.5
   - Flash 0.125s
   - InfoText (damage text)
   - Hit effect animation
   - 2 StarParticles
   - HP bar spawn
   - Sound

3. **Enemy Death**
   - HitCircle (rs=16, duration=0.3)
   - 4 HitParticles (velocity 100-300, duration 0.2-0.5)
   - Sound (enemy_die1 or enemy_die2)

4. **Dagger Attack**
   - Weapon spring pull 0.5
   - Weapon flash 0.2s
   - HitCircle at tip
   - Bullet/projectile spawn
   - Sound (dagger_thrown)
   - Pointer spring pull 0.5

5. **Bullet Hit Wall**
   - HitCircle (rs 6-8)
   - 4 HitParticles in normal direction
   - Hit effect animation
   - Spring pull 0.25
   - Flash 0.15
   - Wall dagger spawn (if dagger)
   - Sound (grass impact + dagger_wall)

When a bullet strikes a wall, I need a smaller impact circle with particles spreading along the surface normal, plus a brief spring and flash effect. If it's a dagger, it should stick to the wall and play both impact and dagger-specific sounds.

6. **Enemy Attack (Alien Shoot)**
   - Charge up: scale tween to 1.2, color tween to white
   - On fire: spring pull 0.35
   - Flash 0.125s
   - Spring shake(8, direction, 250, 75)
   - HitCircle at tip
   - 2-3 HitParticles
   - Sound

The alien attack has a visible charge phase with scaling and color changes, then releases with a spring pull, directional shake, and particles at the impact point.

**emoji-merge:**

1. **Object Click/Hover**
   - HitFX use('

main', 0.25) on click
   - HitFX use('main', 0.125) on hover
   - Sound

Clicking triggers a stronger hit effect than hovering, both with audio feedback. Spawned emojis get a flash effect with randomized particle motion, while the death sequence applies grayscale and staggered hit effects every 0.15s. Dropping emojis uses a spring pull, chain text cascades with 0.066s delays between flashes, and the wind system runs continuously.

The file ends at line 888. Now let me append the high-level composite effects section.

The file E:\a327ex\emoji-ball-battles\reference\emoji_effects_documentation.md has been updated successfully.

I've appended the high-level composite effects analysis to the documentation. Let me verify the file was updated correctly and then run the game to make sure nothing is broken.

1408 E:/a327ex/emoji-ball-battles/reference/emoji_effects_documentation.md

The file went from 888 lines to 1408 lines, so about 520 lines of high-level composite effects documentation was added. Let me also run a quick build to ensure the game still works.

The user doesn't want to proceed with this tool use. The tool use was rejected (eg. if it was a file edit, the new_string was NOT written to the file). STOP what you are doing and wait for the user to tell you how to proceed.

The user wants me to add file names and line numbers to each high-level composite effect so future Claude instances can find the source code. I need to go through each effect in the documentation I just added and add the specific file:line references.

Let me re-read the documentation I added and then cross-reference with the source files to add the specific locations.

In lots of cases it would be unwise to handle what a particular effect needs to do entirely locally, so it's fine to have some things happen elsewhere, but the primary goal would be for it to happen locally.

I've added 25 code references throughout the high-level composite effects documentation. All major effects now have file:line references that future Claude instances can use to find the full source code.

Let me provide a summary for the user.

The user wants me to:

1. Match their described effects to effects in the documentation I created
2. Create an implementation plan section for the implementation plan document
3. Order things logically
4. Ask questions if I have them

Let me analyze each effect they described and match it to the reference effects:

1. **Frame stop / slow-mo on collision** - This matches:
   - "Player Takes Damage" has slow motion: `slow(1, 0.5)`
   - The `emoji-merge-main/anchor/slow.lua` has a slow system
   - Need engine-level time scale or framework-level dt scaling

2. **Ball collision - spring pull + stars** - This matches:
   - "Player Stomps on Enemy" has 3 StarParticles around collision point
   - Spring pull on hit from many examples (0.25-0.3 typical values)
   - `emojunky-one/particles.lua:310` (StarParticle), `super emoji box/main.lua:753` (star_particle)

3. **Weapon hits ball - spring pull + flash** - This matches:
   - "Enemy Takes Damage (Non-lethal)" has flash for 0.1-0.125s and spring pull 0.3-0.5
   - HitFX system from emoji-merge

4. **Animation effect at collision point** - This matches:
   - "Bullet Hits Wall" has "Optional hit effect: Frame-based hit animation (super-emoji-box)"
   - `super emoji box/main.lua:814` (hit_effect) with animation
   - Requires spritesheet support from Engine
   - `lun:animation_frames('hit1', 'hit1', 96, 48)` from super emoji box

5. **Weapons flash on weapon-weapon collision** - Same as flash effects throughout

6. **Plants at bottom of arena** - This matches:
   - "Plant Wind Reaction" with all the wind force systems
   - The user explicitly wants a simpler system than what's in the reference

7. **Ball squish on landing** - This matches:
   - "Player Lands from Jump" with squash/stretch springs
   - `remap(velocity_y, 0, 1000, 0, 1)` for X, `remap(velocity_y, 0, 1000, -0.2, 0)` for Y

8. **Ball squish on unstuck + dash effect** - This matches the same squash/stretch as landing, plus DashParticles from `emojunky-one/particles.lua`

9. **Camera shakes** - Various examples exist throughout with intensity 1-8 and duration 0.25-0.5s, already supported in the framework

10. **Handcam effect** - The `shake\handcam(enabled, amplitude?, frequency?)` API is already available, just needs tuning

For the frame stop versus slow-mo question: these are fundamentally different approaches. Slow-mo scales delta time globally so everything moves slower, while frame stop pauses most objects for a few frames while letting effects continue playing. Frame stop creates that snappier impact feel but requires more complex logic to selectively pause entities.

The spritesheet format for hit animations needs clarification—is it a single row of frames or a grid layout? Animation implementation depends on this. The plant system simplification also needs specifics: should I keep the visual wind sway and object reactions but drop multiple wind types and the physics-based rotation with damping? Finally, there's the stuck sliding detection—does existing logic handle this, or is it a new system to build? And for hit effect animations, will a spritesheet be provided or should I note that as a dependency?

Now I have all the information I need. Let me create the implementation plan. I need to:

1. Match each effect to reference code
2. Identify engine changes needed
3. Identify framework changes needed
4. Order logically

Let me think about the logical order:

**Engine changes needed:**

1. Time scale support (for slow-mo) - affects dt returned to game
2. Spritesheet/animation frame support - loading spritesheets and drawing specific frames

**Framework changes needed:**

1. Slow-mo system (framework level dt scaling)
2. Frame stop/hitstop system (pausing specific objects)
3. Animation class (managing frame-based animations)
4. Plant system (simplified but with all 4 wind types)
5. Star particle class
6. Dash particle class
7. Hit effect class (uses animation)

**Game-level effects (using existing framework):**

- Spring pulls on collision (already have springs)
- Flash on hit (already have flash via layer drawing)
- Camera shake (already have shake system)
- Handcam (already have shake\handcam)
- Squash/stretch on landing (use existing springs)

Logical order:

1. First: Engine changes (time scale, spritesheet support) - foundation
2. Then: Framework time systems (slow-mo, hitstop) - builds on engine
3. Then: Animation system - depends on engine spritesheet support
4. Then: Particle classes (star, dash, hit effect) - may use animation
5. Then: Plant system - independent but uses similar patterns
6. Finally: Game integration - putting it all together

Let me now read the current implementation plan to understand its structure and where to insert this section.

     5→This plan follows the **beginning/end/constraint** framework:

     7→1. **Beginning**: Get the moment-to-moment combat working
     8→2. **End**: Validate power fantasies by implementing actual classes/weapons/items and testing broken builds
     9→3. **Middle**: Only then build the meta loop (draft, evolution, etc.) — planned after Phase 2 findings

    16→
    17→The entire codebase lives in `main.yue`. No separate modules, no `game/` or `data/` folders.
    18→

... [414 more lines]

Now I understand the structure. The implementation plan has:

- Philosophy
- Architecture Principles- Object Tree Structure
- Phase 1: Beginning (Basic Combat) - marked with checkmarks, appears to be done
- Phase 2: End (Broken Builds) - the classes/weapons/items phase
- Phase 3: Middle (Meta Loop) - deferred

The user wants me to insert a new section for visual effects BEFORE the next phase (which would be Phase 2). So this would become Phase 1.5 or Phase 1B, or I should insert it as a new section between Phase 1 and Phase 2.

Looking at the content:- Phase 1.1 to 1.7 are done (checkmarks)

- The user wants effects before Phase 2

I should create a new section like "Phase 1B: Visual Effects" or "Phase 1.8: Visual Effects System" to be inserted after Phase 1.7 but before Phase 2.

Now let me create the implementation plan content. I need to:

1. List what matches from the reference documentation
2. Order things logically by dependencies
3. Include engine changes, framework changes, and game integration

**Logical order:**

**Engine Level (C code in Anchor):**

1. Time scale API (for slow-mo)
2. Spritesheet support (load spritesheet, get frame rect, draw specific frame)

**Framework Level (YueScript in anchor/):**

1. Slow-mo system (uses engine time scale)
2. Hitstop/frame-stop system (framework-level object freezing)
3. Animation class (uses engine spritesheet support)
4. Star particle class
5. Dash particle class
6. Hit effect class (uses animation)
7. Plant system (simplified, all 4 wind types)

**Game Level (main.yue):**
Integration of all effects into collision handlers, ball physics events, etc.

Let me write this out.

The file E:\a327ex\emoji-ball-battles\docs\IMPLEMENTATION_PLAN.md has been updated successfully.

The implementation plan has been updated with the new Phase 1B section. Let me verify the edit was applied correctly by reading a portion of the updated file.

933 E:/a327ex/emoji-ball-battles/docs/IMPLEMENTATION_PLAN.md

The file went from ~444 lines to 933 lines, so about 489 lines were added for the Phase 1B section. Let me verify the structure looks good by checking the table of contents / headers.

The structure looks good. Phase 1B is now properly inserted between Phase 1 and Phase 2, with 13 subsections covering all the effects the user requested.

Let me provide a summary of what was created.

The user is satisfied with the implementation plan. I should acknowledge this and let them know they can proceed when ready. I don't need to do anything else unless they ask for more.

The user has added a new reference project "super emoji pop" to the reference folder. They want me to analyze it for effects, both low-level and high-level, similar to what I did for the other reference games. I should:

1. First explore the new folder structure to understand what files exist
2. Read through the relevant source files
3. Document any new effects not already in the documentation
4. For repeated effects, add the code location + line where they appear

Let me start by exploring the folder structure.

This is "super emoji pop" (or "super emoji clicker" as the window title says). It's a different game from "super emoji box" - this one seems to be a clicker game where you click on emojis to damage them.

Let me analyze the effects:

**Low-level effects found:**

1. **Player cursor juice** (NEW - lines 175-216)
   - Tracks mouse movement deltas over last 10 frames
   - When mouse stops moving after fast horizontal movement: spring pull on rotation (sway effect)
   - When mouse stops moving after fast vertical movement: squash effect (mouse_dt_sy goes to 0.5, then tweens back)
   - Click press: spring pull 0.5, tween rotation and scale (click_r to pi/16, click_sx to 0.9, click_sy to 0.7) over 0.05s
   - Click release: spring pull 0.25, tween rotation and scale back to 0/1/1 over 0.1s

2. **Spawn effect** (lines 358-381) - Similar to emoji-merge but with variations
   - Expanding circle that tweens radius from 0 to target_rs over 0.1s
   - Spawns 6-8 hit particles on expand
   - Then shrinks to 0 over 0.25s
   - Color changes to target_color partway through
   - Optional spawn_action callback when circle expands

3. **Emoji particle** (lines 384-408) - Similar to emoji-merge
   - Emoji flies outward with velocity, shrinks to 0
   - Optional flash_on_spawn
   - fixed_angle option to prevent rotation
   - Spring on spawn

4. **Hit effect** (lines 411-423) - Same as super emoji box
   - Frame-based animation at random angle
   - Uses hit1 spritesheet at 0.03s per frame
   
5. **Hit particle** (lines 426-453) - Rectangle that travels in a direction, scaling based on velocity magnitude, with a color-change method available mid-flight.

6. **Hit circle** (lines 456-475) - Shrinking circular particle with color-change capability.

7. **Fire particle** (lines 297-318) - Circle that shrinks while its color transitions from yellow to red, moving upward with horizontal damping applied.

8. **Emoji text** (lines 321-355) - Floating damage numbers where each character oscillates slightly as it rises.

9. **HP bar** (lines 277-293) - Temporary health indicator displayed above the emoji.

When the player hits an emoji, it springs back with 0.5 pull strength and the impact position derives from the angle between them. When an emoji takes non-lethal damage, it springs with the same force, flashes for 0.125 seconds, spawns a damage number, triggers the hit animation, releases two particles that shift to match the emoji's color, and displays an HP bar above it.

Emoji death triggers a colored hit circle expanding over 0.25 seconds plus four particles matching the emoji's hue, accompanied by a death sound effect. The spawn cascade uses Poisson disc sampling to distribute emojis across space, staggering their appearance by 0.1 seconds each—every spawn includes an expanding circle with particles and 2-3 emoji particles launching outward before the emoji itself flashes into view.

Mouse tracking creates additional juice by monitoring movement deltas. When horizontal motion ceases, the emoji sways based on the average horizontal delta, and when vertical motion stops, a similar sway effect applies based on vertical delta.

Clicking applies immediate rotation and squash deformation (rotating by π/16 and scaling to 0.9 horizontally and 0.7 vertically), then tweens back to normal on release. The crosshair animates with a corner offset bounce pattern and springs when toggled, remaining hidden until activated.

The spawn effect creates an expanding circle with particle emission, while fire particles transition from yellow to red. Several effects repeat across the codebase—hit reactions with emoji pops and particles, text displays, HP bar updates, and spring pulls all appear in multiple locations within the main file, with flash effects triggering on impact.

     2→  Module responsible for anything animation-related.
     3→  It's divided into three different classes: animation, animation_frames and animation_logic.
     4→  animation_frames is located in the lun.yue file as well as the layer.yue file for drawing.

This animation.lua file gives me more details about the animation system used in these games. It has:

1. `animation` class - combines animation_frames with animation_logic
2. `animation_logic` class - handles the timing and frame advancement
   - Can use variable delays per frame (table of delays)
   - Loop modes: 'once', 'loop', 'bounce'
   - Frame callbacks via actions table
   - Index 0 is end-of-animation callback

This is useful for the framework animation class design.

Now let me check the spring.lua and shake.lua files for any additional effects.

Let me find the Enemy Events section to add the new composite effects from super emoji pop.

1095:## Enemy Events

Let me read the Enemy Events section to see where to add the super emoji pop references. The effects from super emoji pop for enemies are similar to existing ones but I should add code locations.

Now let me update the Enemy Death section to include super-emoji-pop.

The file E:\a327ex\emoji-ball-battles\reference\emoji_effects_documentation.md has been updated successfully.

Now let me add the new high-level composite effects unique to super emoji pop:

1. Player hits emoji (cursor attack)
2. Spawn emoji cascade (staggered spawning with effects)
3. Cursor movement juice (as a composite)Let me find a good place to add these. Maybe after the Player Events section.

Based on the summary, I was in the middle of updating the emoji_effects_documentation.md file with effects from super emoji pop. I had already added many sections but still needed to add the remaining high-level composite effects:

1. Player Hits Emoji composite effect (super emoji pop/main.lua:220-225)
2. Spawn Emoji Cascade composite effect (super emoji pop/main.lua:144-157)

Let me continue by reading the current state of the documentation file and adding these remaining effects to Part 2.

Good, I have the context. Now I need to read the Part 2 section of the documentation to see what high-level composite effects are already there and where I should add the new ones from super emoji pop.

I can see the high-level composite effects section. I need to add two more composite effects from super emoji pop:

1. Player Hits Emoji (lines 220-225) - This is a player action composite effect
2. Spawn Emoji Cascade (lines 144-157) - This is a spawn system

Let me continue reading to find the end of the file and see where to add these new sections.

I can see the document continues. Let me check the rest and then add the two missing composite effects from super emoji pop:

1. Player Hits Emoji (from super emoji pop) - belongs in Player Events section  
2. Spawn Emoji Cascade (from super emoji pop) - belongs in Spawn/Death Events section

Let me continue reading to see the end of the file.

Good, I've read through the entire Part 2 section. Now I need to add the two remaining high-level composite effects from super emoji pop:

1. **Player Hits Emoji** - This should go in the Player Events section (after Player Collects Item or before Enemy Events)
2. **Spawn Emoji Cascade** - This should go in Spawn/Death Events section (after Object Spawn with HitFX)

Let me add these two new sections now.

First, I'll add "Player Hits Emoji" in the Player Events section. I'll insert it after "Player Collects Item (Box)" which ends at line 1092.

Then I'll add "Spawn Emoji Cascade" in the Spawn/Death Events section.

The file E:\a327ex\emoji-ball-battles\reference\emoji_effects_documentation.md has been updated successfully.

Good, the first effect has been added. Now let me add the "Spawn Emoji Cascade" effect to the Spawn/Death Events section.

The file E:\a327ex\emoji-ball-battles\reference\emoji_effects_documentation.md has been updated successfully.

I've now added both remaining high-level composite effects from super emoji pop to the documentation:

1. **Player Hits Emoji (Cursor Attack)** - Added to the Player Events section
2. **Spawn Emoji Cascade** - Added to the Spawn/Death Events section

The documentation is now complete with all effects from all four reference emoji games:

- emojunky-one
- emoji-merge
- super-emoji-box  
- super-emoji-pop

Let me verify the additions were made correctly by reading those sections.
