EBB Juice Archeology and Plan

Summary

Session focused on documenting visual effects ("juice") from three reference emoji games and creating an implementation plan for Emoji Ball Battles.

Effects Archeology Task:

API Gaps Analysis:

High-Level Composite Effects:

Implementation Plan (Phase 1B):


Hello, Claude. Let's continue working on the game. The next step is adding combat values in general, I think. But before that, I'd like to add some juice to the game. To do this, I want you go through the 3 folders in reference/ which contain emoji games. emojunky, emoji merge and super emoji box. These are 3 emoji style games I've made in the past, and they contain LOTS of different effects coded in them for various things. I'd like you to go through each game carefully, and document every effect that the games use. Some effects are similar, some are one-offs that only exist for one game (I believe emojunky has the most unique effects), some are the exact same. For ones that are the same you should collapse them into a single category, but when in doubt, separate them. What constitutes the same are small differences like, both effects spawn type of particle X, but one effect in one place spawns 2 particles and another spawns 4 particles, everything else is the same. These are the same effect with just different particle numbers. For each effect, capture everything about it. When it happens, what it affects, what it spawns, which objects it changes with springs, flashes, etc and how, everything that's relevant to the visual/juice aspect of the effect. I'm not interested in gameplay concerns, only having a big list of all emoji effects I've coded so far. The oldest project and most unlike Anchor is emojunky, while the other two are closest and use a proto-Anchor codebase. You should read the API for the framework and make sure that when you document each effect, you also translate how it would be coded in the current Anchor. Don't worry too much about how you code the effects in terms of taste, just be sure you actually use the API correctly. If you don't know if a function exists, read the files. If you don't know how it's called, also read them. Err on the side of caution rather than speed when translating the old code to the new one. Before you start on this ask, ask me any questions you might have. Use the AskUserQuestion tool if you need to. Once you have no more questions, give me a turn before starting the work so I can give you your final instructions.

I have several questions before starting this task.

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.

Got it. Here's my understanding of the task:

Output: Single markdown file in reference/

Scope: All visual/juice effects including borderline ones (knockback, hitstop, slow-mo, camera effects)

Code: Full working Anchor code for each effect translation

Organization: I'll organize by effect type (particles, screen effects, object manipulation, etc.) since that seems most useful for later reference when you want to add juice to specific situations

Process:

  1. Read the Framework API docs thoroughly first
  2. Go through each game (emojunky, emoji merge, super emoji box) systematically
  3. Document every effect with: trigger condition, what it does visually, all parameters
  4. Translate each to current Anchor API with working code
  5. Collapse truly identical effects, separate when in doubt

I'm ready to start once you give final instructions.

Please err on the side of caution and correctness instead of speed. Double check your work, make sure things are correct and that you're not missing anything. You may take as much time as you need on this task, there's absolutely no rush. Be careful and thorough. You may begin.

I'll start by reading the Framework API documentation thoroughly, then explore each game folder systematically.

     8→
     9→The Anchor framework is initialized by requiring it with a configuration table:
    10→
    11→```yuescript
    12→require('anchor')
    13→  width: 640
    14→  height: 360
    15→  title: "My Game"
    16→  scale: 2
    17→  vsync: true
    18→  fullscreen: false
    19→  resizable: true
    20→  filter: "rough"
    21→```
    22→
    23→### Configuration Options
    24→
    25→| Option | Type | Default | Description |
    26→|--------|------|---------|-------------|
    27→| `width` | int | 480 | Game resolution width |
    28→| `height` | int | 270 | Game resolution height |
    29→| `title` | string | "Anchor" | Window title |
    30→| `scale` | int | 3 | Initial window scale multiplier |

Now let me explore the three game folders in the reference directory to understand their structure.

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 analyze the conversation chronologically:

  1. Initial User Request: The user wants to add "juice" (visual effects) to their emoji game. Before doing combat values, they want me to go through 3 reference game folders (emojunky, emoji merge, super emoji box) and document every visual effect used in them. The user specified:

    • Capture everything about each effect (when it happens, what it affects, what it spawns, springs, flashes, etc.)
    • Only visual/juice effects, not gameplay
    • Collapse identical effects, separate when in doubt
    • Translate each effect to current Anchor framework code
    • Read the Framework API to ensure correct translations
    • Be thorough and take time, no rush
  2. Clarification Questions: I asked about:

    • Output format: Single markdown file in reference/
    • Organization: Up to me
    • Code detail: Full working code
    • Scope: Include borderline effects (knockback, hitstop, slow-mo, camera effects)
  3. User's Final Instruction: "Please err on the side of caution and correctness instead of speed. Double check your work, make sure things are correct and that you're not missing anything. You may take as much time as you need on this task, there's absolutely no rush. Be careful and thorough."

  4. My Actions:

    • Read Framework API documentation (FRAMEWORK_API.md and FRAMEWORK_API_QUICK.md)
    • Explored the three game folders' structure
    • Read emojunky-one files: particles.lua, decorations.lua, entities.lua, ui.lua, main.lua, aika.lua
    • Read emoji-merge-main files: main.lua, anchor/hitfx.lua, anchor/shake.lua, anchor/spring.lua, anchor/flash.lua, anchor/camera.lua, anchor/slow.lua
    • Read super emoji box: main.lua (full file)
    • I was in the process of compiling the documentation file when the summary was requested
  5. Key Effects Found:

    • emojunky-one: Particles (dust, blood, fire, smoke, hit sparks), springs on scale, tweens, flashes, camera shake, screen slow-mo, plant/decoration wind effects, weapon effects
    • emoji-merge-main: hitfx system (combined spring + flash), shake system (spring shake + random shake), emoji particles, merge effects
    • super emoji box: hit effects, star particles, dash particles, hit circles, emoji text, plant wind forces, spring-based player animations, enemy charge effects, wall dagger bounce
  6. Current Framework API Key Methods:

    • Springs: @\add spring!, @spring\pull 'main', 0.3, @spring.main.x
    • Timer/Tweens: @timer\tween, @timer\after, @timer\every
    • Shake: an.camera.shake\trauma, an.camera.shake\push, an.camera.shake\shake
    • Layer drawing: layer\image, layer\circle, layer\rectangle, layer\push/pop
    • Color flashing: layer\image img, x, y, nil, white! (flash parameter)

Summary: 1. Primary Request and Intent: The user wants to add visual "juice" effects to their emoji game. Before implementing combat values, they requested a comprehensive documentation of ALL visual effects from 3 reference emoji game projects: - emojunky-one (oldest, pure LÖVE framework) - emoji-merge-main (proto-Anchor) - super emoji box (proto-Anchor/lun)

For each effect, document: when it triggers, what it affects, what particles it spawns, spring/flash/shake parameters - everything visual. Translate each effect to working Anchor framework code. Output as a single markdown file in reference/. Include borderline effects like knockback, hitstop, slow-mo, and camera effects.

  1. Key Technical Concepts:

    • Spring-based animations (scale bounce on hit, weapon recoil)
    • Flash effects (white overlay on hit using shader)
    • Hit effects (hitfx = combined spring + flash system)
    • Camera shake (trauma-based, directional push, random jitter)
    • Slow motion (time multiplier on delta time)
    • Particle systems (emoji particles, hit particles, star particles, dust, blood)
    • Tween animations (position, scale, alpha transitions)
    • Plant/decoration wind physics (constant wind, random wind, moving force, direct force)
    • Animation frames for hit effects
    • Layered rendering with outlines and shadows
  2. Files and Code Sections:

    • E:/a327ex/emoji-ball-battles/docs/FRAMEWORK_API.md

      • Essential for translating old code to new Anchor API
      • Key APIs: spring, timer, shake, layer drawing, collider
    • E:/a327ex/emoji-ball-battles/reference/emojunky-one/particles.lua

      • Contains particle class definitions: dust_particle, blood_particle, hit_particle, etc.
      • Each particle has velocity, rotation, duration, fade behavior
    • E:/a327ex/emoji-ball-battles/reference/emojunky-one/entities.lua

      • Player death effects, weapon effects (sword swing, hammer smash)
      • Spring usage: self.spring = Spring(1), self.spring:pull(0.2)
      • Hitflash: self.hitflash = true with timer to reset
    • E:/a327ex/emoji-ball-battles/reference/emojunky-one/aika.lua

      • Camera shake implementation, Spring class, Timer class
      • camera:shake(intensity, duration, frequency)
    • E:/a327ex/emoji-ball-battles/reference/emoji-merge-main/anchor/hitfx.lua

      • Combined spring + flash system
      • hitfx_use('main', spring_pull, k, d, flash_duration)
    • E:/a327ex/emoji-ball-battles/reference/emoji-merge-main/anchor/shake.lua

      • shake_spring(intensity, r, k, d) - directional spring shake
      • shake_shake(intensity, duration, frequency) - random shake
    • E:/a327ex/emoji-ball-battles/reference/emoji-merge-main/main.lua

      • emoji_particle class with velocity, rotation, flash_on_spawn
      • emoji_merge_effect with tween to target position
      • Various spring pulls on interaction
    • E:/a327ex/emoji-ball-battles/reference/super emoji box/main.lua

      • Full platformer with complete effect implementations:
      • Player jump squash/stretch: spring_pull('jump_x', ...), spring_pull('jump_y', ...)
      • Enemy charge effect with color tween and scale buildup
      • Plant wind system with 4 force types
      • hit_effect (animation), hit_particle (directional), hit_circle (expanding/shrinking)
      • star_particle with visual_angular_speed rotation
  3. Errors and fixes:

    • No errors encountered during file reading
    • entities.lua was too large to read at once, read in 500-line chunks
  4. Problem Solving:

    • Successfully navigated three different codebases with varying architectures
    • Identified the proto-Anchor API patterns vs old LÖVE patterns
    • Mapped old API calls to new Anchor equivalents
  5. All user messages:

    • Initial request explaining the task: go through 3 reference folders, document every effect, translate to Anchor code, output single file
    • Answers to my clarification questions: single file, organization up to me, full working code, include borderline effects
    • Final instruction: "Please err on the side of caution and correctness instead of speed. Double check your work, make sure things are correct and that you're not missing anything. You may take as much time as you need on this task, there's absolutely no rush. Be careful and thorough. You may begin."
  6. Pending Tasks:

    • Write the comprehensive effects documentation markdown file to reference/ folder
    • Document all effects with: trigger conditions, visual description, all parameters
    • Translate each effect to working Anchor YueScript code
  7. Current Work: I had just finished reading all three game codebases and the Anchor Framework API. My todo list shows:

    • [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

    I was about to begin writing the markdown documentation file when the summary was requested.

  8. Optional Next Step: Write the effects documentation file to E:/a327ex/emoji-ball-battles/reference/emoji_effects_documentation.md containing:

    • All effects organized by type (particles, springs, flashes, screen effects, etc.)
    • Full descriptions of when each effect triggers
    • Complete working Anchor YueScript code for each effect

    Direct quote from user's request: "I'd like you to go through each game carefully, and document every effect that the games use... For each effect, capture everything about it... You should read the API for the framework and make sure that when you document each effect, you also translate how it would be coded in the current Anchor."

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-emoji-ball-battles\2bf19487-c663-4b34-a30e-f31d79026b46.jsonl Please continue the conversation from where we left it off without asking the user any further questions. Continue with the last task that you were asked to work on.

I'll continue compiling the effects documentation. Let me re-read the key files to ensure I have all the details correct before writing the comprehensive documentation.

I've written the analysis to reference/effects_api_gaps.md.

Good news: The framework is already well-equipped. Springs, shakes, timers/tweens, and layer flash all exist.

What's missing:

Math utilities (~30 lines total):

Time scale system:

Engine (Optional)

Animation system:

Now let's go back to the emoji effects file. Do another analysis of all effects except from a higher level perspective. For this one you don't need to describe effects in code, just their high level behavior. The descriptions should also focus on higher level descriptions. For instance, You have a bullet/hit particle section describing how the object works. But what about all the different places that use those particles differently? Those higher level effects, which compose multiple of these lower level effects together, should also be captured. Similarly to the previous task, go slow and do it carefully. If you have questions to ask before, do so, otherwise you can start. Remember that these can be described in higher level language, doesn't need to be code, just a description of everything that happens. Although try to use specific values when possible.

A few questions before I start:

AskUserQuestion

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.

I'll append a high-level composite effects section to the existing file. Let me re-read the reference games with a focus on game events and how effects compose together.

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 analyze the conversation chronologically:

  1. Initial Context: The session is a continuation from a previous conversation that ran out of context. The summary indicates:

    • User wants to add visual "juice" effects to their emoji game
    • Three reference game folders were analyzed: emojunky-one, emoji-merge-main, super emoji box
    • A comprehensive effects documentation was created at reference/emoji_effects_documentation.md
    • An API gaps analysis was done at reference/effects_api_gaps.md
    • Math utilities were added to anchor/math.yue
  2. First User Request: "Great, thank you. Now read the engine API and figure out which engine functions as well as framework functions we need to add to cover most of these effects."

    • I read the engine API and framework files
    • Created reference/effects_api_gaps.md documenting missing functions
    • Identified high priority: math utilities, time scale
    • Identified medium priority: animation class, HitFX helper
  3. Second User Request: "Yes." (to add math utilities)

    • Added math functions to anchor/math.yue:
      • math.angle(x, y)
      • math.angle_to_point(x1, y1, x2, y2)
      • math.distance(x1, y1, x2, y2)
      • math.normalize(x, y)
      • math.direction(angle)
      • math.rotate(x, y, angle)
      • math.reflect(angle, normal_x, normal_y)
      • math.snap(value, grid)
      • math.limit(x, y, max)
    • Updated docs/FRAMEWORK_API_QUICK.md to include new functions
    • Verified compilation with run.bat
  4. Third/Current User Request: "Now let's go back to the emoji effects file. Do another analysis of all effects except from a higher level perspective. For this one you don't need to describe effects in code, just their high level behavior. The descriptions should also focus on higher level descriptions. For instance, You have a bullet/hit particle section describing how the object works. But what about all the different places that use those particles differently? Those higher level effects, which compose multiple of these lower level effects together, should also be captured. Similarly to the previous task, go slow and do it carefully. If you have questions to ask before, do so, otherwise you can start. Remember that these can be described in higher level language, doesn't need to be code, just a description of everything that happens. Although try to use specific values when possible."

  5. My clarification questions and user answers:

    • Output format: "Append to existing" (to emoji_effects_documentation.md)
    • Organization: "Doesn't matter to me"
  6. Current work: I started re-reading the reference game files to understand the composite/high-level effects. I read:

    • emojunky-one particles.lua (full)
    • emojunky-one aika.lua (full)
    • emojunky-one entities.lua (lines 1-1000 across multiple reads)

    I was in the middle of gathering information about composite effects like:

    • Player hit effect (flash, spring pull, camera shake, slow-mo, invincibility flicker)
    • Enemy hit effect (flash, spring, info text, star particles, death spawning)
    • Weapon fire effects (boom particle, camera shake, plant force, projectile spawn)
    • Landing effects (camera spring shake, dash particles, plant force)
    • etc.

The task is to append a high-level composite effects section to the existing documentation, describing game events and all the effects that compose them together, with specific values where possible.

Summary: 1. Primary Request and Intent: - The user is adding visual "juice" effects to their emoji ball battles game - Previously: Created comprehensive low-level effects documentation from 3 reference games (emojunky-one, emoji-merge-main, super emoji box) - Previously: Analyzed API gaps and added missing math utilities - Current: Create a higher-level analysis of effects focusing on composite behaviors - how multiple low-level effects combine during game events (e.g., "when enemy is hit" triggers flash + spring + particles + camera shake together). Focus on high-level descriptions with specific parameter values, not code.

  1. Key Technical Concepts:

    • YueScript/Lua game framework (Anchor)
    • Spring-based animations for scale/position feedback
    • Flash effects (white shader overlay)
    • Camera shake (trauma-based, directional spring push)
    • Particle systems (star, dash, fire, emoji particles)
    • Hit effects combining multiple sub-effects
    • Plant/decoration wind physics
    • Slow motion (dt scaling)
    • Composite effects (multiple effects triggered together by game events)
  2. Files and Code Sections:

    • reference/emoji_effects_documentation.md - Existing low-level effects documentation to append to
    • reference/effects_api_gaps.md - API gaps analysis created earlier
    • anchor/math.yue - Added new math utilities: yue math.angle = (x, y) -> math.atan2 y, x math.angle_to_point = (x1, y1, x2, y2) -> math.atan2 y2 - y1, x2 - x1 math.distance = (x1, y1, x2, y2) -> ... math.normalize = (x, y) -> ... math.direction = (angle) -> math.cos(angle), math.sin(angle) math.rotate = (x, y, angle) -> ... math.reflect = (angle, normal_x, normal_y) -> ... math.snap = (value, grid) -> math.floor(value/grid + 0.5) * grid math.limit = (x, y, max) -> ...
    • docs/FRAMEWORK_API_QUICK.md - Updated with new Vector & Angle section
    • reference/emojunky-one/particles.lua - Contains particle classes (FireParticle, StarParticle, DashParticle, BulletParticle, BoomParticle, etc.)
    • reference/emojunky-one/aika.lua - Contains Spring, Timer, Camera, Shake classes
    • reference/emojunky-one/entities.lua - Contains composite effects for Player and Enemy hits:
      • Player:hit() - spring pull 0.25, camera shake(4, 0.4), slow(1, 0.5), invincibility flicker every 0.05s for 2s
      • Blob:hit() - flash for 0.1s, spring pull 0.3, InfoText, death spawns EnemyDead + StarParticles
      • Player landing - camera spring_shake based on velocity, DashParticles, plant force
      • Weapon fire - BoomParticle, camera shake, plant direct force, projectile spawn
  3. Errors and fixes:

    • No errors encountered in this session
    • Math utilities compiled and ran successfully
  4. Problem Solving:

    • Successfully identified API gaps between effects documentation and framework capabilities
    • Added all missing math utilities to the framework
    • Currently gathering information for high-level composite effects analysis
  5. All user messages:

    • "Great, thank you. Now read the engine API and figure out which engine functions as well as framework functions we need to add to cover most of these effects."
    • "Yes." (confirming to add math utilities)
    • "Now let's go back to the emoji effects file. Do another analysis of all effects except from a higher level perspective. For this one you don't need to describe effects in code, just their high level behavior. The descriptions should also focus on higher level descriptions. For instance, You have a bullet/hit particle section describing how the object works. But what about all the different places that use those particles differently?

Remember that these can be described in higher level language, doesn't need to be code, just a description of everything that happens. Although try to use specific values when possible."
    • Clarification answers: Output="Append to existing", Organization="Doesn't matter to me"
  6. Pending Tasks:

    • Complete high-level composite effects analysis and append to reference/emoji_effects_documentation.md
    • Document all game events and their composite effect combinations with specific values
  7. Current Work: I was re-reading the reference game source files to gather information about composite/high-level effects. I had just read through:

    • emojunky-one/particles.lua (all particle types)
    • emojunky-one/aika.lua (Spring, Camera, Shake classes)
    • emojunky-one/entities.lua (Player and Enemy hit handlers, weapon effects)

    Key composite effects identified from entities.lua:

    • Player:hit(): spring pull(0.25), camera shake(4, 0.4), slow(1, 0.5), invincibility flicker every 0.05s
    • Blob:hit(): flash 0.1s, spring pull(0.3), InfoText, death=EnemyDead + 4 StarParticles
    • Player landing: camera spring_shake(velocity-based, pi/2), 2 DashParticles, plant force(distance-based 75-25)
    • Gun fire: BoomParticle, plant direct force, camera shake(4, 0.25), Bullet projectile
  8. Optional Next Step: Continue reading reference files (emoji-merge-main, super emoji box) to gather more composite effect patterns, then write the high-level effects section to append to reference/emoji_effects_documentation.md.

    Direct quote from user: "Do another analysis of all effects except from a higher level perspective... Those higher level effects, which compose multiple of these lower level effects together, should also be captured... go slow and do it carefully... Remember that these can be described in higher level language, doesn't need to be code, just a description of everything that happens. Although try to use specific values when possible."

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-emoji-ball-battles\2bf19487-c663-4b34-a30e-f31d79026b46.jsonl Please continue the conversation from where we left it off without asking the user any further questions. Continue with the last task that you were asked to work on.

I'll continue gathering information from the reference games to complete the high-level composite effects analysis. Let me read more from the other reference games.

Edit (E:\a327ex\emoji-ball-battles\reference\emoji_effects_documentation.md)

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 it was added correctly.

Bash (wc -l E:/a327ex/emoji-ball-battles/reference/emoji_effects_documentation.md)

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

The documentation has been expanded from 888 to 1408 lines. Let me run the game to ensure everything still works.

Bash (cd E:/a327ex/emoji-ball-battles && ./run.bat 2>&1 | head -35)

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.

This is perfect and exactly what I wanted. For all high-level composite effects, could you also add file names and line numbers where they appear? This is so future Claude instances know where to look for the full code of each effect.

I'll add file and line references to each composite effect. Let me go through the source files systematically to get the exact line numbers.

   891→# Part 2: High-Level Composite Effects
   892→
   893→This section describes the composite effects that occur during game events — how multiple low-level effects combine together to create impactful moments.

   901→**Source:** emojunky-one, super-emoji-box
   902→
   903→When the player is hit by an enemy or hazard, multiple systems activate simultaneously to create a strong "ouch" moment:
   904→
   905→1. **Scale feedback:** Spring pull of 0.25 on hit spring, causing player to briefly shrink
   906→2. **Camera shake:** Intensity 4, duration 0.4 seconds — substantial screen shake
   907→3. **Slow motion:** Time scale drops to 1x for 0.5 seconds (creates a "freeze frame" effect)
   908→4. **Invincibility flicker:** Player visibility toggles every 0.05 seconds for 2 seconds total (40 flickers)
   909→5. **State change:** Player emoji changes to "hit" expression for 0.25 seconds
   910→6. **Sound:** Hit sound effect
   911→7. **UI feedback:** Heart breaks/shakes, remaining hearts pulse if HP is low (≤3)
   912→
   913→The combination creates a noticeable moment where:
   914→- The game briefly pauses (slow-mo)
   915→- Everything shakes
   916→- Player visually shrinks and flickers
   917→- UI responds with breaking hearts

I've added file and line number references to all 25 high-level composite effects in the documentation. Here's a summary of what was added:

Player Events (4 effects):

Enemy Events (5 effects):

Weapon Events (6 effects):

Projectile Events (3 effects):

UI Events (3 effects):

Environment Events (1 effect):

Spawn/Death Events (3 effects):

Particle Classes (reference block):

Perfect. Now I'm going to describe all the effects I want to add to Emoji Ball Battles. You will match what I described to what can be reused from all the effects you just listed in that file. After matching, you will create an interim section in the implementation plan (before the next one), and this section will contain an implementation plan to implement all those effects as well as the required changes to both the Engine and Framework. You will order the plan such that things follow a logical implementation path. Ask me questions if you have them before doing the whole task. Now the description of effects:

When weapons or balls hit each other, the game will either slow down a small amount of time, or most objects (except visual effects) will stop a little, creating a "frame stop" effect to add weight to the collision

When balls hit each other, their spring will be pulled a little, stars will spawn around the collision point

When a weapon hits a ball, the ball that takes damage will have its spring pulled and flash

When weapons hit each other or when a weapon hits a ball, the animation effect will play at the collision point, this requires an animation module in the Framework and the ability to read spritesheets from the Engine

When weapons hit each other they will flash (to be tested)

Plants will be added to the bottom of the arena and both balls and weapons will interact and apply forces to them, we must refactor the old plant system so that the new one is significantly simpler implementation-wise

When balls hit the bottom of the arena they will squish as though they landed from a jump

When balls get unstuck after being stuck sliding on the floor, they will squish as though they jumped, and a dash effect will play

Camera shakes are to be tested, might be too much to apply them on every collision

Handcam effect to be tested to make the arena wobble a little and give some motion to an otherwise static game

I think this is it. I may be forgetting some but this is fine for now.

Good list. I have a few questions before creating the implementation plan:

  1. Frame stop vs slow-mo: You mentioned two options - "slow down a small amount of time" OR "objects stop a little (frame stop)". These are different:

    • Slow-mo: Scale dt globally (like the reference games do with slow(1, 0.5)) - everything moves slower including effects
    • Frame stop (hitstop): Most game objects freeze for a few frames while visual effects continue playing normally

    Frame stop gives more "impact weight" but is more complex to implement (need to flag which objects freeze). Which do you want, or both to test?

  2. Animation spritesheet: For the hit effect animation at collision points:

    • Do you have a spritesheet ready, or should I just ensure the system can load one when you provide it?
    • What format - single horizontal row of frames, or a grid?
    • The reference uses 96x48 total for the hit effect with animation_frames('hit1', 'hit1', 96, 48)
  3. Plant simplification: You want a significantly simpler plant system. The reference has 4 types of wind force:

    • Constant wind (ambient sine wave sway)
    • Random wind stream (area gusts)
    • Moving force (entity passing through)
    • Direct force (impacts from landing/weapons)

    Do you want just one or two of these? My suggestion would be: constant ambient sway + direct force from nearby impacts. Drop the complex velocity-based "moving through" detection.

  4. "Stuck sliding" detection: When balls get unstuck after sliding - how does the game currently detect this? Is there existing logic, or should I add detection for "ball was moving slowly along floor, then got knocked upward"?

  5. Star particles: Do you want to reuse the existing star emoji, or should stars be simple geometric shapes (like white rectangles that shrink)?

  1. Both. 2. I have it in assets/hit1.png, I believe it's still 96, 48 per frame. It's a horizontal spritesheet, but we should support both, we should also support padding. The animation system itself needs to be rethought to work with Anchor. The old one has a few complexities that need to be reasoned about more carefully, so you may defer details about it in the plan. 3. I want all four. We may test if they don't feel different enough and then remove any that feel redundant later. But I do want the code in general to be simplified, which I believe is possible. 4. There is existing logic and a place where it happens. Slotting the effect into the game is easy and you shouldn't worry about it. 5. Reuse the emoji, it's already in assets/star.png.

Let me read the current implementation plan to understand its structure and find the right place to insert this section.

I've added Phase 1B: Visual Effects to the implementation plan. Here's a summary of what's included:

Reference Mapping (1B.0):

Engine Changes (to add to ENGINE_WANTS.md):

Framework Additions (13 sections):

Game Integration:

Implementation Order Summary:

  1. Engine batch (time scale + spritesheet) → add to ENGINE_WANTS.md
  2. Framework: slow-mo → hitstop → animation → particles → plants
  3. Game: ball modifications → collision handlers → camera tuning

Assets needed:

This seems good, thank you.

You're welcome. The plan is ready in docs/IMPLEMENTATION_PLAN.md. When you're ready to start implementing, the logical first step would be adding the engine requirements (time scale and spritesheet support) to docs/ENGINE_WANTS.md so they can be batched into an Engine Mode session.
