Enable the Rapier events you intend to read

Collision and contact callbacks need active events on the relevant collider.

Rule text

1 line
When collision callbacks appear silent in Rapier, confirm that active collision events are enabled on the collider and that the event queue is drained after each physics step.

Why it helps

The reasoning behind the entry

The event system is opt-in, so listener code alone does not make colliders emit events.
