What problem does it solve? Adding realistic physics to React Three Fiber 3D scenes requires wiring up the Rapier physics engine correctly—rigid bodies, colliders, forces, joints, and collision events all have specific APIs that are easy to misuse. This Skill provides complete, working patterns for every common physics scenario so you can build interactive 3D experiences without digging through documentation. ## Core Features & Use Cases - Rigid Bodies & Colliders: Create dynamic, fixed, and kinematic bodies with automatic or manual colliders (cuboid, ball, hull, trimesh, capsule, and more). - Forces, Joints & Sensors: Apply impulses and continuous forces, connect bodies with fixed, revolute, spherical, prismatic, spring, and rope joints, and detect overlaps with sensor colliders. - Collision Events & Groups: Handle collision enter/exit callbacks, filter interactions with collision groups, and access the Rapier world for gravity changes, manual stepping, and state snapshots. - Use Case: Build a physics-based game where a player knocks over stacked boxes, triggers a goal sensor, and swings from a rope joint—all configured declaratively in JSX. ## Quick Start Ask the AI to add Rapier physics to your React Three Fiber scene, for example by creating a falling box that collides with a static ground plane.
