- The interim cue tables and their opt-outs are gone; the native runtime is the only audio path. Old
settings/audio.json files still load ("interim" / "native" ignored). Missing native data logs an error
instead of falling back.
- Water splash from retail's mechanism (SFXObj_OffBoard start / update): Skate_Collisions 1187 / 1197 once
per water stay, 1198 when the board is in water.
- The random interim riding bed is removed; riding collision and cloth sounds compared with the recomp
(doc 11). Native output otherwise byte-identical (13 scenarios + 5 sessions).
- Published tools under tools/ (one folder per tool with a README; the recomp ones labelled for use with the
research hooks), doc 14 and PR plan bucket L.
- Docs: doc 11 (retirement, bail density measured against the recomp, collision posts), doc 13 (usage guide).

"""Extract one district's collision triangles for analysis (does not touch the install).
|
|
|
|
Usage (repo root): py -3.13 tools/collision-inspect/map_collision.py MegaPark [--disc DIR] [--work DIR]
|
|
Extracts world<District>.big from the disc into <work>/<District>/raw if needed, then writes
|
|
<work>/<District>/collision.npy (N x 3 x 3 float64, Y-up metres) and
|
|
prints the bounds and the spawn the current map_writer rule would choose.
|
|
Parks take ~1 s; city districts take minutes and a lot of memory.
