EBB YueScript to Lua
Summary
Converted the entire emoji-ball-battles codebase from YueScript to Lua — 5099 lines of YueScript across 25+ classes became 5798 lines of idiomatic Lua, with zero runtime bugs on first run.
Planning and Approach:
- Examined the existing
main.lua(auto-compiled from YueScript) and determined it was too ugly/minified to clean up — decided on a from-scratch conversion from the.yuesource - Identified the full file structure: setup code (lines 1-337), arena class (338-1428), ball class (1429-2386), 14 UI/effect classes (2387-3234), projectile + remaining classes (3235-4071), headless/utility functions (4072-5100)
- Established YueScript → Lua translation rules:
@→self.,\method→:method(),class extends→:extend(),continue→goto,unless→if not,+=→ explicit, string interpolation → concatenation, etc. - User chose: convert main.yue by hand, copy framework files from Anchor/framework/anchor/, archive .yue files in reference/yue/
Framework File Setup:
- Copied all 17
.luafiles fromAnchor/framework/anchor/toemoji-ball-battles/anchor/(including newclass.lua) - Archived all
.yuefiles (bothmain.yueandanchor/*.yue) toreference/yue/ - Removed
.yuefiles from their original locations
Parallel Conversion (6 agents):
- Part 1: Setup + draw function (lines 1-337) — initialization, layers, assets, draw pipeline
- Part 2: Arena class (lines 338-1428) — collision handling, energy system, plants, cloud system
- Part 3: Ball class (lines 1429-2386) — 24 methods covering weapons, physics, combat, all 5 weapon types
- Part 4: UI + effect classes (lines 2387-3234) — hp_bar, cooldown_bar, hp_ui, weapon_ui, star_particle, emoji_particle, hit_circle, boom_particle, fire_particle, sword_flame, hit_particle, afterimage, dash_particle, hit_effect
- Part 5: Projectile + remaining classes (lines 3235-4071) — projectile (5 subtypes), damage_number, status_text, emoji_text, plant, dying_plant, stuck_arrow, dying_knife, deflected_arrow, wall
- Part 6: Headless/utility functions (lines 4072-5100) — 12 utility functions, render mode with ffmpeg pipeline, headless simulation, visual mode entry point
Assembly and Verification:
- Concatenated 6 parts into single
main.lua(5798 lines) - Ran automated checks: no stray
@references, no backslash method calls, nosuperkeywords, no#{}string interpolation, no!=operators, nounlesskeywords - User tested — zero runtime bugs on first run
Line Ending Fix:
- Concatenation via
catproduced mixed CRLF/LF line endings - User noticed immediately ("End of each line for the entire file is wrong")
- Normalized to consistent CRLF throughout to match project convention
YueScript Reference Cleanup:
- Searched entire project for YueScript mentions
- Updated
run.bat,simulate.bat,balance.bat— removedyue.execompilation lines - Updated
reference/headless-usage.md— removed "compile YueScript" mention, changedmain.yue→main.lua - Noted
yue.exestill in directory as dead weight, docs inreference/andreference/archives/still have YueScript examples (left as historical)
Memory Update:
- Updated auto-memory: changed "Code Style - Emoji Ball Battles (YueScript)" header to "(Lua)", fixed code fence from
yuescripttolua, added conversion history note
Hi, we just changed Anchor from YueScript to Lua, and now we need to do the same for emoji-ball-battles.
Let me start by understanding the current state of both the Anchor framework (already converted to Lua) and emoji-ball-battles (still in YueScript).

balance.bat

So emoji-ball-battles has both main.yue and main.lua. Let me check the current state of both, and also look at how the Anchor framework Lua code looks now for style reference.

The game's anchor/ folder still has both .yue and .lua files. The main Anchor framework has already been converted. Let me check a few things:
- Is the existing
main.luaa YueScript-compiled output or a hand-written Lua conversion? - Are the game's
anchor/*.luafiles the old compiled ones or the new converted ones fromAnchor/framework/anchor/?

Now I can see the situation clearly. The existing main.lua in emoji-ball-battles looks like it was auto-compiled from YueScript (note the odd formatting — blank lines, everything crammed together). The game's anchor/ folder still has old .yue and compiled .lua files that need to be replaced with the new hand-written Lua versions from Anchor/framework/anchor/.
This is a big task. Let me ask some clarifying questions:
AskUserQuestion
User has answered your questions: "How should we approach the main.lua conversion?"="Convert main.yue to Lua by hand", "For the anchor/ folder in emoji-ball-battles, should I just copy over the already-converted files from Anchor/framework/anchor/?"="Yes, copy from Anchor/framework", "Should I delete the .yue files after conversion is complete?"="Keep the .yue files in a folder in reference/" user notes: Keep the .yue files in a folder in reference/. You can now continue with the user's answers in mind.
Got it. Let me start by reading the full main.yue to understand the complete codebase, and also look at the Anchor framework Lua style for reference. Then I'll work through the conversion incrementally.
Let me first copy over the framework files and archive the .yue files, then start on the main.lua conversion.

Good — framework files are updated and now include class.lua which is new. Now let me read the full main.yue to understand the entire game codebase before converting.

500→ 2. HIGH SPEED BYPASS (creates pacing/rhythm) - ball-ball collisions
501→ Problem: Constant high-speed action becomes monotonous and hard to follow.
502→ Solution: Track consecutive high-speed hits. As count increases, probability of
503→ bypassing grows (S-curve, guaranteed at 9 hits). When bypass triggers, balls
504→ lose 30% energy, creating calm moments. Counter resets after bypass.
505→
506→ 3. LOW HORIZONTAL VELOCITY PREVENTION (prevents stalling) - ball-ball collisions
507→ Problem: Balls can end up with low horizontal velocity, bouncing mostly vertically,
508→ making collisions rare and gameplay stall.
509→ Solution: Track consecutive low-horizontal collisions.
510→ Probability of intervention increases linearly (guaranteed at 4 hits).
511→ When intervention triggers, both balls get random horizontal impulse (100-200).
512→
513→ 4. WALL FALLBACK (prevents stalling) - ball-wall collisions
514→ Problem: System energy can drop too low even with other systems in place.
515→ Solution: Track system_energy (sum of both ball speeds) on ball-ball collisions.
516→ On ball-wall collisions, probabilistically apply energy boost.
517→ - Probability (quad_out): 100% at energy ≤100, drops fast to 0% at energy ≥600
518→ - Boost value (sine_out): max at energy ≤250, drops to 1.0 at energy ≥400
519→
520→ 5. STUCK BALL DETECTION (prevents floor sliding) - implemented in ball class
521→ Problem: A ball can lose vertical velocity and slide along a wall indefinitely.
522→ Solution: Each ball tracks how long its vertical velocity stays very low (|vy| < 5)
523→ while still having horizontal movement (|vx| > 5). If this persists for >0.5 seconds,
524→ apply impulse to unstick it.
525→
526→ 6. WEAPON ENERGY BOOST (compensates for weapon collision energy loss) - weapon-weapon collisions
527→ Problem: Weapon collisions drain energy from the system.
528→ Solution: Apply @weapon_energy_boost (1.14x) on weapon-weapon collisions.
529→ Also cap linear speed at @max_ball_speed and angular velocity at ball.max_angular_velocity.

The existing main.lua is clearly YueScript-compiled output — it's minified/ugly with no comments, no proper formatting, everything on single lines. It's not worth cleaning up; a from-scratch conversion from the .yue source will produce much better results.
This is a massive task (~5000 lines). Let me break it into manageable pieces. I'll convert section by section, showing you each piece for review. Let me also check how the new Anchor framework handles class definitions since that's the key syntax change.

Now let me look at how classes work in the converted framework — specifically how object extends class, and how an existing framework class that extends object looks.

Now I have a clear picture of the target Lua style. Key patterns for the conversion:
YueScript → Lua translation rules:
class foo extends object→foo = object:extend()new: (...) =>→function foo:new(...)super 'name'→object.new(self, 'name')@field→self.field@\method args→self:method(args)obj\method args→obj:method(args)func arg1, arg2→func(arg1, arg2)(parentheses required in Lua){key: val}→{key = val}for item in *list→for _, item in ipairs(list)continue→goto continuewith::continue::labelcontinue if cond/continue unless cond→if cond then goto continue endunless→if notx += 1→x = x + 1cloud_positions[] = val→table.insert(cloud_positions, val)"string #{expr}"→"string " .. tostring(expr)or string.format- YueScript's
ifas expression → needs variable assignment ->(arrow function) →function() ... end(args) =>→function(self, args) ... endglobal *(line 1) → removed (YueScript-specific, makes all locals global)
This is a large conversion. Let me work through it in sections, starting with the top-level setup code (lines 1-337), then the arena class, then ball, and so on. I'll convert in chunks and show you each one.
Let me start with the first section — the initialization and setup code (lines 1-337). This is the most mechanical part.

Now I have the full picture. 5100 lines of YueScript. Let me partition this into chunks and convert them in parallel using multiple agents. I also need to read the remaining parts I haven't seen yet (the arena methods, ball class, and all the smaller classes).
Let me launch parallel conversion agents. I'll partition as follows:
- Setup + draw (lines 1-337) + Arena class (lines 338-1428)
- Ball class (lines 1429-2386)
- UI classes + small effect classes (lines 2387-3234)
- Projectile + remaining classes (lines 3235-4071)
- Headless/utility functions (lines 4072-5100)
But first I need to read the parts I haven't seen yet before launching agents.

Now I have a comprehensive understanding of the full codebase. This is a ~5100 line conversion. Let me launch parallel agents to convert different sections simultaneously. Each agent will get the YueScript source for its section plus the conversion rules.

I've launched 6 parallel conversion agents, each handling a different section of the 5100-line file:
- Setup + draw function (lines 1-337) — initialization, layers, assets, draw pipeline
- Arena class (lines 338-1428) — collision handling, energy system, plants
- Ball class (lines 1429-2386) — weapons, physics, combat
- UI + effect classes (lines 2387-3234) — hp_bar, weapon_ui, particles, etc.
- Projectile + remaining classes (lines 3235-4071) — projectile, plant, wall, etc.
- Headless/utility functions (lines 4072-5100) — simulation, reports, entry point
They're all working in the background. Once they finish, I'll assemble the parts into a single main.lua and review for any conversion issues. I'll update you when they're done.

projectile(line 2) -- Bullets, arrows, spirals, boomerangs, kitchen knives. The largest class withnew,update, andhitmethods. Handles 5 projectile subtypes with type-specific setup, physics, drawing, and collision responses.
damage_number(line 383) -- Emoji digits that float upward and fade. Per-digit wobble animation with spring pop on spawn.
status_text(line 438) -- Font-based text with per-character shake and progress fill (channeling/using modes). Uses stencil masking for fill effect. Has adiemethod that scatters characters with individual physics.
emoji_text(line 560) -- Floating emoji text for status messages like "+1 DMG". Each character is a child object with its own layer, rotation, and wobble.
plant(line 628) -- Decorative plants that sway and react to physics. Dual force system (moving/direct), ambient sway, and death probability that increases with accumulated forces.
dying_plant(line 796) -- Visual-only remnant that floats away with gravity, dampened velocity, and blinks before disappearing.
stuck_arrow(line 856) -- Visual-only arrow embedded in a wall. Blinks out after a delay.
dying_knife(line 883) -- Visual-only knife that spins and blinks out after a parallel wall hit. Gravity and lerp dampening on velocities.
deflected_arrow(line 921) -- Visual-only arrow knocked away by a weapon parry. Damping + gravity physics.

- weapon_ui (lines 174-427) -- The largest class. Displays emoji face, weapon icon with handcam shake, bowstring rendering for bow type, stat text, and multiple event handlers (hit, shoot, reflect, boomerang_wall_hit, landed_hit)
- star_particle (lines 431-458) -- Collision star that spins and shrinks
- emoji_particle (lines 462-516) -- Generic emoji projectile with gravity, angle modes, flash-on-spawn spring
- hit_circle (lines 520-547) -- Expanding/shrinking circle at impact with optional flash
- boom_particle (lines 551-571) -- Muzzle flash boom image that scales to zero
- fire_particle (lines 575-607) -- Circle that rises, color-lerps from yellow to red, and shrinks
- sword_flame (lines 611-846) -- The second largest class. Candle-like procedural flame with wind physics, direct force physics, per-segment wobble, and quad-based rendering
- hit_particle (lines 850-894) -- Rectangle that shoots outward with gravity and shrinks
- afterimage (lines 898-932) -- Fading ghost sprite using captured push transforms
- dash_particle (lines 936-964) -- Unstick-from-floor particle with spring pop and fade
- hit_effect (lines 968-989) -- Frame-based hit animation using spritesheet
Key conversion decisions:
color!pattern:black()andred()in hp_bar store packed RGBA integers (fromcolor.__call), matching how they're used directly in draw calls without further unpacking. In cooldown_bar,color(0,0,0,160)stores color objects because they're later called withself.bg_color().fire_particle.color_2: The YueScriptcolor(255, 60, 20)!would create a packed integer, but.r/.g/.bare accessed later for tweening. I stored it as a color object (without()) so the field access works correctly -- this fixes what appears to be a bug in the original YueScript.- List comprehensions in sword_flame (phase arrays, segment offsets): Converted to explicit
forloops withtable.insert.- Operator spacing:

All parts look good. Let me also quickly check the tail of each part to make sure they end cleanly, then concatenate them.
Bash (tail -10 E:/a327ex/emoji-ball-battles/main_part6.lua)

local visual_args = {}
if an.args then
if an.args.seed then visual_args.seed = tonumber(an.args.seed) end

visual_args.player_weapon, visual_args.enemy_weapon = an.args.matchup:match('(%w+),(%w+)')
end
end
an:add(arena(visual_args))
end
All parts end cleanly. Now let me concatenate them into the final main.lua.
Bash (cat E:/a327ex/emoji-ball-battles/main_part1.lua > E:/a327ex/emoji-ball-battles/m...)
Bash (wc -l E:/a327ex/emoji-ball-battles/main.lua)
5798 E:/a327ex/emoji-ball-battles/main.lua
Good, 5798 lines. Now let me clean up the part files and do a basic Lua syntax check.
Bash (cd E:/a327ex/emoji-ball-battles && luac -p main.lua 2>&1 || echo "luac not found...)
/usr/bin/bash: line 1: luac: command not found

/usr/bin/bash: line 1: luajit: command not found
No Lua compiler available for syntax check
No Lua compiler available for a syntax check, but the game uses the Anchor engine's built-in Lua. Let me do a manual scan for common conversion issues — unmatched ends, stray YueScript syntax, etc.

Good — no stray backslash method calls, no @ references, no bare super keywords. The continue references are all properly wrapped in goto continue patterns. Let me also check for any stray YueScript string interpolation #{} that wasn't converted.

No string interpolation #{} remnants, no YueScript class extends, no != (should be ~= in Lua), no unless. All clean. Let me also verify the yue.exe is no longer needed and check the final state.

Everything is in order. Here's a summary of what was done:
Conversion complete:
main.lua— 5798 lines of hand-written Lua (converted from 5099 lines of YueScript)anchor/— 17 Lua files copied from the already-convertedAnchor/framework/anchor/(includes newclass.lua)- All
.yuefiles archived toreference/yue/
What changed:
- All YueScript syntax → idiomatic Lua (
@→self.,\method→:method(), etc.) class foo extends object→foo = object:extend()with separatefunction foo:method()definitions- YueScript sugar (
continue,unless,+=, string interpolation, inline ifs) → Lua equivalents - Comments preserved throughout
Still in directory but no longer needed:
yue.exe— you can delete this whenever you want since YueScript is no longer used
Go ahead and try running it — I expect there'll likely be a few runtime issues to iron out given the size of the conversion, but the syntax should be solid.
End of each line for the entire file is wrong.
[Request interrupted by user]
End of each line for the entire file is wrong. The return character I mean.
Let me check what's happening with the line endings.
Bash (file E:/a327ex/emoji-ball-battles/main.lua)
E:/a327ex/emoji-ball-battles/main.lua: ASCII text, with CRLF, LF line terminators
Mixed line endings — CRLF and LF. The cat concatenation mixed them up. Let me also check what the original framework files use so I match.
Bash (file E:/a327ex/Anchor/framework/anchor/object.lua)
E:/a327ex/Anchor/framework/anchor/object.lua: JavaScript source, ASCII text, with CRLF line terminators
Framework uses CRLF. Let me normalize main.lua to CRLF throughout.
Bash (sed -i 's/\r$//' E:/a327ex/emoji-ball-battles/main.lua && sed -i 's/$/\r/' E:/a3...)
Bash (file E:/a327ex/emoji-ball-battles/main.lua)
E:/a327ex/emoji-ball-battles/main.lua: ASCII text, with CRLF line terminators
Fixed — now consistent CRLF throughout, matching the rest of the project.
Perfect, thank you.
You're welcome! Go ahead and give it a test run. With a 5800-line conversion there'll probably be a few runtime bugs to squash, but the structure and syntax should be solid. Let me know what comes up.
There are no bugs, it just works.
That's excellent — 5100 lines of YueScript converted to Lua across 25+ classes with zero runtime bugs. Clean conversion.
The yue.exe in the emoji-ball-battles directory is now dead weight if you want to remove it at some point.
Run a thorough search of the folder for any mentions of YueScript in docs, files or other documents, just tell me where they're all at.

The three .bat files are the only ones that actually matter for the game to work. The rest are docs and reference projects. Want me to fix the bat files?
Update the 3 bat files, update headless-usage.

Perfect, thank you, I think that's it. Do you see any other places for possible improvements?
A few small things I noticed:
yue.exeis still sitting in the directory. Safe to delete — it's ~2MB of dead weight now.docs/folder — the CLAUDE.md referencesemoji-ball-battles/docs/FRAMEWORK_API_QUICK.mdandFRAMEWORK_API.md. If those were copied from the Anchor framework before the Lua conversion, they might have stale YueScript examples. Worth checking if they should be refreshed fromAnchor/docs/.Memory file — my auto-memory has a section titled "Code Style - Emoji Ball Battles (YueScript)" with the operator spacing convention. The convention still applies, but the "(YueScript)" label is outdated. I can update that.
None of these are urgent. Want me to handle any of them?
Yes, update the memory.

The file C:/Users/adn/.claude/projects/E--a327ex/memory/MEMORY.md has been updated successfully.
Done. Updated the language label from "YueScript" to "Lua", fixed the code fence from yuescript to lua, and added a brief note about the conversion for future context.
