It's not necessarily working without compare tag, it might be picking up a different object collision so try debug the other. Here is my code: using Description Sent when another object enters a trigger collider attached to this object (2D physics only). Looks like it’s not on a similar layer. Log is doing nothing so I'm stump OnTriggerEnter is invoked when two GameObjects with a Collider component touch or overlap, and one of the Collider components has the Collider. Sphere Collider is a CircleCollider2D). I have ran the debug log and it seems to not even execute “OnTriggerEnter”. the child of that object is an empty with a sphere collider trigger that is larger than the box collider. e.
