Triggers

Colliders can be set as triggers, this allows them to detect collisions without being affected by them.

This example shows a box collider that is set as a trigger and a falling box.

When the falling box collides with the trigger, a message will be logged to the console.

this.world!.config.collisionClasses.push({ name: 'Trigger' });

new TRigidBodyComponent(
  { mass: 0, isTrigger: true },
  createBoxCollider(1, 1, 1, 'Trigger'),
);

this.events.addListener(
  TEventTypesPhysics.COLLISION_START,
  'Trigger',
  (event: TCollisionStartEvent) => {
    if (event.payload.entityA === box) {
      console.log('Collision started', event);
    }
  },
);
