Scene Physics Composition

scene_physics is the 3D runtime composition satellite exposed as scenePhysics. bindGeneratedColliders(world3D) routes later procgen collider publications into the same caller-owned gameplay World3D used for stepping and queries. Scene and procgen remain independent producers/consumers; the physics artifact provider owns only its published bodies and shapes.

isGeneratedColliderWorldBound() reports whether the shared collider world is still live. unbindGeneratedColliders() removes an empty live binding; it is a no-op when already unbound and raises a script error when committed or staged publications still exist.

Binding requires an empty collider provider. Unbinding also requires no committed or staged publications. Destroying the caller-owned world makes existing collider records observably stale rather than retaining a raw world pointer. Clear publications before an orderly unbind.
