EBB Boomerang 2
Summary
Session focused on adding saw and boomerang to the headless balance test, removing mirror matchups, then iterating on boomerang balance — changing its firing logic, adding wall bouncing, and tuning until balanced.
Adding Saw/Boomerang to Balance Test & Removing Mirrors:
- Added
'saw'and'boomerang'toheadless_weaponslist (line ~4051), expanding from 4 to 6 weapons - Changed balance loop from
for j = itofor j = i + 1in both the battle-running and results-reading loops to eliminate mirror matchups (dagger vs dagger, etc.) - Updated matchup count formula from
n*(n+1)/2ton*(n-1)/2— 15 matchups instead of 21 - Removed Mirror Match Sanity Check section from HTML report
- Handled matrix diagonal (show
—for self-matchups instead of looking up nil data) balance.batwas updated from 5 battles to 100 battles per matchup
Weapon Filter for balance.bat:
- Added
--weaponCLI arg support:balance.bat boomerangruns only matchups involving boomerang (5 instead of 15) - Built matchup list with filter:
if not headless_filter or wa == headless_filter or wb == headless_filter - Fixed indentation error after restructuring loops from nested
for i/for jto singlefor _, pair in ipairs - Fixed report crash when filtered —
win_rate[w][opp]was nil for missing matchups; added nil guards in tier ranking and matrix display - First run without filter ran all 15 matchups (1500 battles, ~18 min); filtered runs took ~5 min (500 battles)
Boomerang Firing Logic Change (Cooldown-Based):
- Original:
timer\whenpollingboomerang_ready and boomerang_is_aligned— fired only when aimed at enemy - Changed to:
timer\after boomerang_cooldown— fires purely on cooldown, regardless of aim - Updated re-arm logic in projectile catch code (line ~3272) to also fire on cooldown
- Removed
@boomerang_ready = falsefromboomerang_firesince the flag was no longer used - User noted "I just used the word randomly randomly" when asked about random timing
Boomerang Cooldown Tuning:
- Tested at 2.0s cooldown (down from 3.0s) — ran balance test
- Reverted to 3.0s cooldown for final version
Wall Bouncing Implementation:
- Added
an\physics_collision 'boomerang_projectile', 'wall'— boomerang now physically collides with walls - Wall bounce in
projectile.hit: reflectsboomerang_move_angleusingmath.reflectoff wall normal, keeping circular motion intact - Added collision event handler after spiral projectile section: spawns hit_circle + hit_particles at collision point
- Key insight: since the update loop overwrites velocity from
boomerang_move_angleevery frame, reflectingboomerang_move_angle(not just the physics velocity) is essential
Safe-Fire Check (Prevent Firing Into Walls):
- Added
boomerang_check_side_safe(side)— raycasts 40px in the trajectory direction (@angle + side*pi/4) to check for walls - Added
boomerang_can_fire()— checks both sides (+1, -1), returns safe side or false if both blocked - Reverted to
timer\whenpattern: cooldown → pollboomerang_can_fireeach frame → fire when safe boomerang_firecallsboomerang_can_fireitself to determine the safe side, returns early if neither side is safe- Re-added
@boomerang_readyflag for the cooldown cycle
Wood Sounds for Wall Bounce:
- Converted 3 WAV files:
Wood Heavy 2/6/8.wav→wood_heavy_1/2/3.oggusing ffmpeg - Measured dB levels: wood_heavy_1 (-26.8 dB → 1.0), wood_heavy_2 (-22.8 dB → 0.63), wood_heavy_3 (-25.3 dB → 0.84)
- Added normalization comments following existing pattern in sound loading section
- Replaced concrete sound with wood sound in boomerang wall collision handler
- Volume tuned: initially 0.63-1.0, reduced 33% to 0.42-0.67, then raised 10% to 0.46-0.74
- Deleted original .wav files from assets folder
Weapon UI Effects on Wall Bounce:
- Added
boomerang_wall_hitmethod toweapon_uiclass - Flashes weapon white (
@weapon_flashing = truefor 0.1s) - Springs weapon rotation (
@spring\pull 'weapon_rotation') - Spawns brown hit_circle + hit_particles randomly around UI boomerang position
- Called from arena's boomerang-wall collision handler via
owner.weapon_ui\boomerang_wall_hit!
Particle Color:
- Changed boomerang wall hit particles from yellow to brown (193, 105, 79)
- Updated existing
browncolor definition from195, 105, 77to193, 105, 79
Balance Results:
- Initial run (no changes): boomerang was "way too strong"
- After cooldown-based firing + wall bouncing + safe-fire check at 3s cooldown: "it is now balanced"
Hi, let's add the saw and boomerang to the headless mode big test. Let's also remove the mirror matchups, and then let's run the program. Before running, tell me your understanding of everything you have to do/have done.
Let me start by reading the required files to get acquainted with the project.

Good. Now I have a full picture. Let me also check how the matchup count formula is used in the report print — since removing mirror matchups changes it:

4233→ f\write "<h2>Win Rate Matrix</h2>\n"
4234→ f\write "<p style='font-size:0.85em;color:#888;'>Row weapon's win rate vs column weapon</p>\n"
OK, here's my understanding before I make any changes. Let me present it to you:
What I need to do:
Add 'saw' and 'boomerang' to the
headless_weaponslist (line 4051). Currently it's{'dagger', 'sword', 'bow', 'gun'}. It will become{'dagger', 'sword', 'bow', 'gun', 'saw', 'boomerang'}.Remove mirror matchups from the balance test. Currently the loops use
for j = i, #headless_weaponswhich includesi == j(mirror matchups like dagger vs dagger). I need to change this tofor j = i + 1, #headless_weaponsin both places:- Line 4351: the battle-running loop
- Line 4379: the results-reading loop
Update the matchup count formula in the print statement (line 4345). Currently it's
#headless_weapons*(#headless_weapons + 1)/2which counts mirrors. Without mirrors it becomes#headless_weapons*(#headless_weapons - 1)/2. With 6 weapons that's 15 matchups instead of 21.Remove the Mirror Match Sanity Check section from
headless_write_balance_report(lines 4222-4230), since we won't have mirror data anymore. The win rate matrix will also have no diagonal data — I should handle that: the matrix cell forwa == wbshould show-or similar instead of trying to look up data that doesn't exist.Run
balance.batafter making the changes so the simulation executes.
One concern: The win_rate matrix building (lines 4148-4156) and the tier ranking (lines 4158-4168) both expect win_rate[w][w] to exist for the mirror sanity check, and the matrix display (line 4244) references mirror cells. With no mirror matchups, win_rate[wa][wb] where wa == wb will be nil. I need to handle that in:
- The matrix display (show
-for diagonal) - The tier ranking code already only sums non-mirror (
opp != w), so that's fine - The mirror sanity check section — just remove it entirely
Does this all look right, or do you want me to adjust anything before I make the changes?
Yes.
Let me make all the changes.

4383→ all_matchups[] = {weapon_a: wa, weapon_b: wb, :results}
4384→ else

I need to be careful about uniqueness — both lines have the same text for j = i, #headless_weapons. Let me use more surrounding context for each edit:

Since there are no mirror matchups anymore, I should clean up the is_mirror variable and the unless is_mirror guard — all matchups will now have distinct weapons, so the enemy HP histogram should always show:

All 15 matchups completed successfully. No mirror matchups (no dagger vs dagger, etc.), and saw + boomerang are included. 75 total battles (15 matchups × 5 battles each), finished in 65 seconds. The balance report was written to results/balance_report_2026-02-20_2226.html.
I doubt they completed this fast... really? Open it.

Opened. And yeah, 5 battles per matchup is pretty tiny — that's what balance.bat has hardcoded (--battles=5). 75 battles total at that count finishes fast. The results won't be statistically meaningful at all with only 5 samples per matchup though. Want me to bump the battle count?
Ah, that's why. We did 100 battles per match up the first time.

All 15 new matchups have .dat files (the extra ones are leftovers from the old run with mirrors). It looks like it might actually be done or nearly done — let me check for any remaining .tmp files and whether the process is still writing the report:

There's a second report balance_report_2026-02-20_2229.html — that's from the 100-battle run. The 16 .tmp files are just leftovers. It's likely finished or wrapping up. Let me wait for the task to complete:

The boomerang is currently way too strong... Let me think about how to make it more balanced...
Take your time. I'll be here when you're ready.
Let's try making it fire randomly based on a cooldown instead of always firing when its aligned with the enemy.
Let me look at the current firing logic in detail.

So currently line 1640 uses @timer\when which polls every frame until @boomerang_ready and @\boomerang_is_aligned! is true, then fires. The change would be: once the cooldown finishes (@boomerang_ready = true), just fire immediately — no alignment check. Here's what I'd change:
-- Current (line 1640):
@timer\when (-> @boomerang_ready and @\boomerang_is_aligned!), 'boomerang_fire', (-> @\boomerang_fire!)
-- Proposed:
@timer\after @boomerang_cooldown, 'boomerang_fire', -> @\boomerang_fire!
This way it fires purely on cooldown — every 3 seconds (the current @boomerang_cooldown) it just throws regardless of alignment. The boomerang_is_aligned method and the separate boomerang_ready flag become unused.
That said — firing exactly on cooldown is deterministic, not random. Did you mean you want some randomness in the timing too? Like cooldown + a random delay (e.g. 3.0 + random 0-1s)? Or is "fires when cooldown expires" what you had in mind?
No, I just used the word randomly randomly. Your solution is right, go ahead.

Line 3246 re-arms with the old pattern — sets boomerang_ready after cooldown, but nothing triggers the fire. I need to change that to directly fire after cooldown, same as the initial setup:

Done. The boomerang now fires purely on cooldown timer — no alignment check. The boomerang_ready flag and boomerang_is_aligned method are now dead code, but I'll leave them for now since they're harmless.
Let's run the balance test again, but only of the boomerang vs. other weapons. If you have to, change the balance.bat file to allow for such an option.
Let me look at the balance loop to see where to add filtering.

I'll add a --weapon filter arg. When provided, the balance loop only runs matchups that include that weapon. Here's the plan:
- In
main.yue, readan.args.weaponand filter the matchup loops - Update
balance.batto pass--weapon=%1when an argument is given
So you'd run balance.bat boomerang to test only boomerang matchups, or just balance.bat for all.

Hmm — it ran all 15 matchups, not just the 5 boomerang ones. The --weapon filter didn't work. The print says "15.0 matchups" which means headless_filter was nil. Let me check — the issue is likely that %~1 in the bat file didn't get passed through, or an.args.weapon isn't being parsed correctly. Let me check how args are parsed.
Grep (an.args)
4310: headless_battles = tonumber(an.args.battles) or 1
4311: headless_matchup = an.args.matchup or 'dagger,sword'
4313: headless_base_seed = tonumber(an.args.seed) or 1
4317: if an.args.report
4328: elseif an.args.balance
4330: headless_parallel = tonumber(an.args.parallel) or 8
4331: headless_filter = an.args.weapon
4389: headless_parallel = tonumber(an.args.parallel) or 1
4462: if an.args
4463: visual_args.seed = tonumber(an.args.seed) if an.args.seed
4464: if an.args.matchup
4465: visual_args.player_weapon, visual_args.enemy_weapon = an.args.matchup\match('(%w+),(%w+)')
[Showing results with pagination = limit: 15, offset: 0]
The code looks right — an.args.weapon should work if the engine parses --weapon=boomerang. The problem is the bat file likely ran correctly but something else happened. Let me verify the bat file is correct and test it:
Read (E:/a327ex/emoji-ball-battles/balance.bat)

The bat file looks fine. The issue might be that bash invoked it as ./balance.bat boomerang but the argument didn't get passed through the bash-to-cmd bridge. Let me try invoking it with cmd:
Bash (cd E:/a327ex/emoji-ball-battles && cmd //c "balance.bat boomerang")

'balance.bat' is not recognized as an internal or external command,

The cmd //c approach didn't work with the path. Let me stop that and try differently:
TaskStop

Let me just add a debug print to verify the arg is reaching the Lua code, and try a simpler approach — pass the weapon arg directly:

Right — lines 4351-4371 are indented for the old double-nested for i / for j but now they're under a single for _, pair loop. I need to dedent them by 4 spaces (one level):

Let's try the following changes. The boomerang now can hit the walls. When it does, it bounces off it, but maintains its overall circular motion, with just its immediately velocity vector flipping according to the bounce. Additionally, we should add a way so that we don't fire the boomerang if it's going to go straight into a wall. So we shouldn't fire it if its 1. too close to a wall and 2. aimed at the wall. The direction of the boomerang is a bit random, so we need to calculate that first and take into account. We need to then keep trying to fire until we're safe to do so. All this after the cooldown is ready, of course.
Let me study the boomerang's movement, physics setup, and the arena walls to understand everything involved.

Now let me check what collisions the boomerang_projectile currently has — it seems like there's no physics_collision call for it, so it probably doesn't collide with walls. Let me check:
Grep (physics_collision)
236:an\physics_collision 'ball', 'wall'
237:an\physics_collision 'ball', 'ball'
238:an\physics_collision 'weapon', 'weapon'
240:an\physics_collision 'projectile', 'wall'
241:an\physics_collision 'projectile', 'weapon'
245:an\physics_collision 'spiral_projectile', 'wall'
So boomerang_projectile has no collision with wall — it currently passes right through. Now let me check what happens when projectiles hit walls (to understand the pattern):

2235→
2236→ flash_ball: (duration=0.15) =>
2237→ @ball_flashing = true
OK, now I have the full picture. Here's my plan:
1. Wall collision: Add an\physics_collision 'boomerang_projectile', 'wall' and handle the bounce in the hit method. On wall hit, reflect @boomerang_move_angle using the wall normal, but keep the circular motion going (the @boomerang_turn_rate continues unchanged).
2. Wall-safe firing: The boomerang's initial move angle is @angle + side*math.pi/4 where side is random (+1 or -1). So we need to check both possible trajectories. For each, raycast from the spawn point in that direction and check if we'd immediately hit a wall (within some short distance). If both are bad, don't fire — wait and retry. If only one is safe, use that one. If both are safe, pick randomly as before.
For the firing, this means going back to a timer\when pattern: after cooldown expires, poll each frame checking boomerang_can_fire_safely, then fire.
Does this look right? One question — for the wall bounce, should I just reflect boomerang_move_angle and let the physics handle the actual position bounce, or should I override the velocity entirely after the collision?
I think reflecting boomerang_move_angle is the key part — since the update loop sets velocity from boomerang_move_angle every frame, the physics bounce would get overwritten immediately. So on wall hit I need to reflect boomerang_move_angle and let the update loop take over from there.
Here's the code. For the wall bounce handling in projectile.hit:
elseif @projectile_type == 'boomerang'
-- Reflect move angle off wall normal
@boomerang_move_angle = math.reflect_angle @boomerang_move_angle, normal_x, normal_y
Wait, let me check if math.reflect_angle exists or if I need to do the math manually.
Grep (reflect)
583:math.reflect(angle, normal_x, normal_y) -> number
math.reflect exists. Here's the plan for all changes:
1. Physics collision setup (near line 248):
yuescript
an\physics_collision 'boomerang_projectile', 'wall'
2. Wall bounce in projectile.hit (after the spiral case, ~line 3319):
yuescript
elseif @projectile_type == 'boomerang'
@boomerang_move_angle = math.reflect @boomerang_move_angle, normal_x, normal_y
3. Safe-fire check in boomerang_fire — pick a safe side, raycast to check wall proximity:
- Try both sides (+1, -1)
- For each, compute the initial move angle (
@angle + side*math.pi/4) - Raycast a short distance (~40px) in that direction from spawn point
- If it hits a wall, that side is unsafe
- If both safe, pick randomly. If one safe, use that. If neither safe, don't fire (return false).
4. Firing logic — change from pure timer\after back to a timer\when pattern: after cooldown, poll boomerang_can_fire which checks wall safety.
Does this look right to you?
OK.

Now update the firing trigger to use timer\when that keeps retrying until boomerang_fire succeeds. The issue is that boomerang_fire now returns early if not safe, so I need the trigger to keep polling. Let me change the approach — use timer\when with boomerang_can_fire as the condition:

Now I need to fix boomerang_fire — since we're back to using boomerang_ready, I should reset it in boomerang_fire, and the boomerang_can_fire check in timer\when already guarantees it's safe, so boomerang_fire doesn't need to re-check. But the timer\when condition calls boomerang_can_fire which returns two values — however in a boolean context only the first matters. The side still needs to be determined at fire time. Let me keep the check in boomerang_fire since it also picks the side:
Read (E:/a327ex/emoji-ball-battles/main.yue)
2231→ safe_minus = @\boomerang_check_side_safe -1

2240→ boomerang_fire: =>

2242→ return unless can_fire

2252→ projectile_type: 'boomerang'
2253→ direction: @angle
2254→ team: @team

Good — boomerang_fire calls boomerang_can_fire itself to get the side, and returns early if somehow not safe. I should also add @boomerang_ready = false back so the cooldown cycle works properly:

Ready for you to test.
Convert the new Wood sounds to .ogg, normalize them according to the values in the sound loading portion of the file, make it so that one of them plays randomly whenever the boomerang hits a wall. Keep the particles that spawn when a boomerang hits a wall the same, but make their color 193, 105, 79 (brown).

I see the pattern. The normalization comment shows the dB level and a target volume factor. Let me first measure the dB of the Wood Heavy files, convert them to ogg, normalize, then wire them up.
Bash (which ffmpeg 2>/dev/null || which sox 2>/dev/null || echo "no audio tools found")
/c/Users/adn/bin/ffmpeg
Bash (ffmpeg -i "E:/a327ex/emoji-ball-battles/assets/Wood Heavy 8.wav" -af volumedetec...)
[Parsed_volumedetect_0 @ 000001a7636b6880] mean_volume: -25.3 dB
Now I need to understand the normalization pattern. Looking at the comments, the reference level seems to be the quietest sound in a group getting factor 1.0. Let me look at the concrete sounds (since those are the current wall-hit sounds) for reference. The pattern is: the quietest sound (highest dB magnitude) gets normalized to 1.0, and louder ones get scaled down proportionally.
For the wood sounds, I'll normalize to the quietest one (-26.8 dB = Wood Heavy 2):
- Wood Heavy 2: -26.8 dB → 1.0
- Wood Heavy 8: -25.3 dB → 10^((-26.8 - (-25.3))/20) = 10^(-1.5/20) = 0.84
- Wood Heavy 6: -22.8 dB → 10^((-26.8 - (-22.8))/20) = 10^(-4.0/20) = 0.63
Let me convert all three to ogg:
Bash (ffmpeg -y -i "E:/a327ex/emoji-ball-battles/assets/Wood Heavy 8.wav" -c:a libvorb...)

There's already a brown color defined as 195, 105, 77 — very close to the requested 193, 105, 79. Let me use the exact requested values. I'll update the existing brown or just use inline. Actually, the existing brown is close enough that I should ask — but the user gave specific values. Let me just update the brown color definition to match exactly and use brown in the handler.

Weapon UI should flash white, spring (if the original projectile also does) and have particles spawned in the same way whenever the boomerang hits the wall. The hit circle + particles should be spawned randomly around the weapon UI boomerangs position.

Now let me check the projectile's spring/flash behavior on spawn (the original projectile):

3196→ @boomerang_sound_angle = 0
3197→ @\add collider 'boomerang_projectile', 'dynamic', 'box', @w, @h
The projectile has a spring that gets pulled on hit (@spring\pull 'hit', 0.5*intensity, 3, 0.5 in projectile.hit). So the weapon UI should also spring and flash.
Now I need to add a method to weapon_ui for the boomerang wall bounce effect. Let me add a boomerang_wall_hit method that: flashes the weapon white, pulls the weapon spring, and spawns brown hit_circle + hit_particles around the weapon UI position.
Edit (E:/a327ex/emoji-ball-battles/main.yue)

Now I need to call this from the boomerang wall collision handler. The projectile needs to reach its owner's weapon_ui. Let me check how the projectile finds its owner:

Great to hear! The boomerang changes worked out well — firing on cooldown instead of on alignment, wall bouncing with the reflect + safe-fire check, and the 3s cooldown all came together to a balanced state.
