Western Heart Dev Sandbox

A mobile-first 3D dev sandbox for Western Heart and other games. Inspect real rigged models, tune jiggle, soft-body (XPBD), ragdoll (Rapier), face and visemes, foot IK, and moveset frame data, and run two-model fights with an AI test harness. Stills and video can be captured from any lab. The older 2D demos and drills are under Archive.

Gestures

  • Tap — spawn a ball (or select a body)
  • Double-tap — shockwave blast
  • Press & hold — grab a body, release to fling it
  • Drag — pull bodies around on a spring
  • Pinch — zoom the camera
  • Two-finger drag — pan the camera
  • Swipe ←/→ — switch demo scenes

Open-source stack

  • matter-js — 2D physics engine (MIT)
  • hammer.js — touch gesture recognition (MIT)
  • marked — markdown rendering (MIT)

Vendored dist files + licenses live in vendor/. Works offline once loaded (service worker).
