Is there a simple way to make a BoxCollider2D ignore a specified BoxCollider2D, maybe a layer mask or something similar? Maybe i could just move the objects on the Z axis since it’s a 2D game but I don’t like that too much.
Got it… One was a polygon collider 
So using … wouldn’t work (2 box colliders)
