    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!





    Hi Günther!
