xb-physics
xb-physics is a Game development skill for AI agents, published by google in the xrblocks repository on GitHub. Skillspace rates xb-physics D (57/100) and it passed the safety scan; the rating is based on static analysis only.
Add rigid-body physics to an XR Blocks app using the Rapier3D engine — gravity, collisions, and (with xb-depth) colliders that match real-world geometry so virtual objects bounce off the floor and furniture. Use for ball pits, throwing/ dropping objects, projectiles, or any depth-aware physical interaction. Covers enabling physics via `options.physics.RAPIER`, the `initPhysics(physics)` / `physicsStep()` Script hooks, and the depth-mesh collider recipe. There is no `enablePhysics()` method — assigning `options.physics.RAPIER` is what turns it on.
