Character pipeline (tools/): - sketchfab_import.py: search/download via Sketchfab Download API with license/attribution tracking (SKETCHFAB_API_TOKEN) - autorig.py: headless Blender auto-rig — fits a Mixamo-named skeleton to unrigged humanoids, binds automatic weights - merge_animations.py: merges the shared Mixamo-skeleton animation library onto any rigged character, strips root motion, canonical names - pipeline.py: one command chains download -> rig -> animate -> register In-game skin system: - SkinManager autoload reads skins.json (auto-written by the pipeline) - SkinnedPlayerModel rewritten: canonical clips with fallback chains, blend times, speed-scaled locomotion, weapon bone attachment - First-person: full animated body for the owner, head hidden via SkeletonModifier3D; third-person: full model for other players - Skin selector in main menu; skin id synced in multiplayer - Fixed GLBLoader crash (GLTFDocument.get_animation_count doesn't exist) Multiplayer sync overhaul: - Movement is now client-authoritative: the owning peer simulates locally (no input round-trip), server keeps health/kills/death - Remote players interpolate synced_position/velocity with extrapolation and snap-on-teleport - Knockback/impulses routed to the simulating peer Audio: - AudioManager autoload: SFX/Weapons/Footsteps/UI/Music buses, pooled 3D players, variation + pitch randomization, auto-registration from assets/sounds Docs: 3D_ASSET_PIPELINE.md rewritten end-to-end, new ASSET_SOURCES.md (non-procedural animation/map/sound sources) and SOUND_DESIGN.md. Verified with debug/spawn_smoke_test.gd (headless: 24/24 checks pass). Co-Authored-By: Claude Fable 5 <[email protected]>

# Sound Design Plan
|
|
|
|
The current sounds are procedurally generated sine/noise blends
|
|
(`generate_sounds.py`) — functional, but robotic. This doc is the path to
|
|
real sound design with zero budget.
|
|
|
|
## What's in place now
|
|
|
|
`AudioManager` (autoload, `globals/audio_manager.gd`) provides the plumbing
|
|
good sound design needs:
|
|
|
|
- **Bus layout**: `Master ← SFX ← {Weapons, Footsteps, UI}`, `Master ← Music`
|
|
— created automatically at boot, so volume sliders and effects (EQ,
|
|
compression, reverb zones) can target categories.
|
|
- **Variation playback**: drop `footstep_01.wav`, `footstep_02.wav`,
|
|
`footstep_03.wav` into `assets/sounds/` and `AudioManager.play_3d("footstep", pos)`
|
|
picks one at random.
|
|
- **Pitch randomization**: every playback is pitched ±6% by default — the
|
|
single cheapest trick to stop repeated sounds sounding fake.
|
|
- **Pooled 3D players**: `play_3d()` is safe to call every frame; no node
|
|
churn, no cut-off management.
|
|
|
|
```gdscript
|
|
# anywhere in gameplay code:
|
|
AudioManager.play_3d("ak47_fire", muzzle.global_position)
|
|
AudioManager.play_ui("hit_confirm")
|
|
```
|
|
|
|
## Replacing the procedural sounds (priority order)
|
|
|
|
Sound is ~50% of "game feel" in an FPS. Replace in this order:
|
|
|
|
1. **Weapon fire** (heard constantly): layered = body (low thump) + crack
|
|
(mid transient) + tail (room reflection). Sonniss GDC packs have complete
|
|
layered gunshots. One file per weapon is fine to start; add `_01.._03`
|
|
variations later.
|
|
2. **Hit confirm + kill confirm**: short, bright, satisfying (this is the
|
|
"touchdown" pillar in the design doc).
|
|
3. **Footsteps**: 4+ variations minimum, quieter than you think, on the
|
|
`Footsteps` bus so they can be ducked while firing.
|
|
4. **Movement verbs**: slide (cloth+concrete scrape), dash (air whoosh),
|
|
wall-run loop, jump/land (land intensity scaled by fall speed).
|
|
5. **Ambience**: a quiet room tone per map kills the "dead air" feeling.
|
|
6. **UI**: menu hover/click/equip from a Kenney UI pack.
|
|
|
|
Where to get files: see [ASSET_SOURCES.md](ASSET_SOURCES.md#sounds) —
|
|
Sonniss GDC bundles first, Kenney CC0 packs second, Freesound (CC0 filter)
|
|
for gaps.
|
|
|
|
## Conventions
|
|
|
|
- Files: `assets/sounds/<event>[_NN].wav` — 44.1 kHz, 16-bit, mono for 3D
|
|
positional sounds, stereo only for UI/music.
|
|
- Ids are auto-registered from filenames at boot (`ak47_fire.wav` →
|
|
`"ak47_fire"`). Names containing `fire`/`reload` route to the Weapons bus,
|
|
`footstep` to Footsteps, everything else to SFX
|
|
(see `BUS_HINTS` in audio_manager.gd).
|
|
- Keep source loudness consistent: normalize weapon shots to about -6 dBFS
|
|
peak, footsteps/foley around -18 dBFS.
|
|
|
|
## Later polish (cheap wins, in order)
|
|
|
|
1. Distance low-pass on the Weapons bus (far gunfire sounds muffled).
|
|
2. A short duck (sidechain) on Footsteps/ambience when local weapon fires.
|
|
3. Reverb `AudioEffectReverb` per-map on SFX for indoor spaces.
|
|
4. Surface-dependent footsteps: raycast down, map material → sound id
|
|
(`footstep_metal`, `footstep_concrete`).
