obb-collider
Collision system using Oriented Bounding Boxes based on THREE.OBB.
It checks collision accross all entities with the obb-collider component. It emits events when bounding boxes start and stop intersecting.
Example
<a-entity obb-collider></a-entity>
|
Set showColliders to true on the scene to render colliders for debugging purposes:
<a-scene obb-collider="showColliders: true"></a-scene>
