What problem does it solve? Building 3D scenes and games in React typically requires writing verbose imperative Three.js code by hand. This Skill lets you define entire 3D scenes, physics simulations, and game levels as declarative JSON prefabs that render through React Three Fiber, WebGPU, and Rapier Physics. ## Core Features & Use Cases - JSON-First Scene Definition: Describe GameObjects with Transform, Geometry, Material, Physics, Model, Light, and Text components in a simple JSON schema, then render them with PrefabEditor or PrefabRoot. - Physics & Game Events: Configure Rapier rigid bodies (dynamic, fixed, kinematic), sensors, and collision events, and wire gameplay logic through a typed game event system. - GLB Export & Editor Tooling: Author scenes visually with transform gizmos, then export the result to GLB format programmatically via exportGLBData. - Use Case: Ask the agent to generate a JSON prefab for a platformer level with a floor, walls, a bouncy ball, and a coin pickup sensor, then export the rendered scene as a GLB asset. ## Quick Start Ask the agent to generate a JSON prefab for a 3D scene with a textured floor, a red box with dynamic physics, and a spotlight, then render it with PrefabEditor.
