Hello,

I have a project where it contains some entities that collide with each other and one of them should be deleted.

for example, A wall and a box (like the boxes example) and when a box hits the wall it should be deleted. I know I can set the collision in the ball, not on the wall but I have other objects when they hit the wall they also should be deleted. So, is it possible to get the id of the box so I can delete it with ( entityManager.removeEntityById(“Ball ID”) ).

Hi Asaad!

When creating entities with e.g. EntityManager::createEntityFromUrl you get the entityId of the created entity as return value of the function.

If you like to access the entity of a collision, you can do so like this:

BoxCollider {
  // ...
    fixture.onBeginContact: {
      var collidedEntity = other.getBody().target
      console.log("entityId: "+collidedEntity.entityId)
    }
}

Hope this helps!

Best,
Günther
