useCollisionGroups

This hook can be used in conjunction with the component <CollisionGroups>. It uses the collision groups provided by a parent <CollisionGroups> component and lets you easily apply them to colliders.

<script>
  import { useRapier, useCollisionGroups } from '@threlte/rapier'

  const { world } = useRapier()
  const { registerColliders, removeColliders } = useCollisionGroups()

  const collider = world.createCollider(colliderDesc)

  // collider will be assigned the collision groups
  // provided by a parent `<CollisionGroups>` component.
  registerColliders([collider])

  onDestroy(() => {
    removeColliders([collider])
  })
</script>

Types

const {
  registerColliders, // (colliders: RAPIER.Collider[]) => void
  removeColliders // (colliders: RAPIER.Collider[]) => void
} = useCollisionGroups()
