What it does

godzilla.sfx

Synthesized sound effects + 4-layer adaptive music for the Godzilla in San Francisco game.

All audio is pure-Luau DSP rendered to 22050 Hz 16-bit mono PCM WAV files under /zero/source/godzilla/audio/<name>.wav by M.ensureAssets() (idempotent; skips files that already exist). Playback spawns temporary entities carrying the builtin Audio component; nothing it plays is saved into the scene.

API

  • M.ensureAssets(): boolean — synthesize every missing WAV. Edit mode only (VFS writes are locked in play mode). Returns true when every file exists.
  • M.play(name, opts?): string — one-shot playback, returns the entity id. opts = { volume?, pitch?, pos = {x,y,z}?, loop? }. Spatial when pos is given. Loops (loop = true) must be stopped by despawning the returned entity id.
  • M.tick(dt) — reaps finished one-shots and crossfades music layer volumes. The game calls this every frame.
  • M.musicStart() / M.musicStop() — spawn/despawn the 4 looping music layers (calm / tense / battle / frenzy; same length, tempo, and key so they stack).
  • M.musicSetThreat(level, frenzy) — level 0..5 + frenzy boolean map to per-layer target volumes; M.tick lerps live volumes toward the targets.
  • M.setVolumes({ master?, sfx?, music? }) — 0..1 gains multiplied into every Audio component volume this module manages, applied live to running loops and music.

Sounds

roar, swipe, grab, throw, stomp, step, tail, crumble, breath_charge, breath_loop, explosion, tank_fire, jet_pass, missile, rotor, cannon, siren, chime, combo, frenzy, gameover, splash plus music layers music_calm, music_tense, music_battle, music_frenzy (6.4 s seamless loops, 75 BPM, D minor). breath_loop, rotor, and siren are seamless-loopable (exact-period oscillators + crossfaded noise).

Interface

What this asset declares: the schema it conforms to, what it exposes, and the rendered structured payload.

conforms to

zero/source-extract/v2

godzilla.sfx — synthesized WAV sound effects + 4-layer adaptive music. ensureAssets() renders every sound with pure-Luau DSP (22050 Hz, 16-bit mono PCM) into /zero/source/godzilla/audio/. Playback spawns temporary entities with the builtin Audio component; tick(dt) reaps finished one-shots and crossfades music.

Seamlessly-loopable lowpassed noise: renders n+fade samples and crossfades the tail into the head so sample n flows back into sample 1.
