collider_active_events

Event handlers are user-defined callbacks used to be notified when two colliders start/stop touching. By default no collision event is generated by the narrow-phase. In order to enable a collision event for a pair of colliders, at least one of the involved colliders must have the corresponding event set as active. An event is activated for a collider by setting its corresponding active events bit to 1:

• Setting the ActiveEvents.COLLISION_EVENTS bit to 1 enables the collision events involving the collider.

The active events of a collider can be set when the collider is created or after its creation:

# Set the active events when the collider is created.
collider = rp.Collider.ball(0.5).active_events(rp.ActiveEvents.COLLISION_EVENTS).build()

# Set the active events after the collider creation.
collider = world.colliders[collider_handle]
collider.active_events = rp.ActiveEvents.COLLISION_EVENTS
assert collider.active_events.contains(rp.ActiveEvents.COLLISION_EVENTS)
