Rust Bevy Collision Broadphase
Use this skill to make Bevy collision detection scale without mixing detection,
response, rendering, and gameplay rules into one system.
Core Workflow
- Identify the collision shapes, movement model, entity counts, and layers.
- Keep collider data small and independent from sprites, textures, and game
rules.
- Choose the cheapest broadphase that fits the scene: brute force for tiny
counts, spatial hash for uniform worlds, quad tree for clustered worlds.
- Emit candidate or collision events; let separate systems decide response.
- Test edge contacts, fast movement, layer filters, despawn cases, and
deterministic ordering.
- Benchmark before and after changing the broadphase.
