Question Destroying one way platform

Hi,

Using the one way platform effector is very simple and straightforward, that's great, however I can't figure how to use colliders to detroy the platform when it is outside the screen.

My favorite idea was to use a edgeCollider2D trigger attached to the camera's lower bound, so any platform passing through would be destroyed from OnTriggerEnter2D. The problem is this callback is not called because of the platforms' effector.

Instead I could check the platform position and detect wether it is out of screen, but I prefer not to do so for performance concerns.

 

I'm pretty sure an event fires when an object goes off screen.

Code (CSharp):

1.  void OnBecameInvisible() {
2.          Destroy(gameObject);
3.      }

 

Are you even experiencing performance issues if you don't apply this potential fix?
