Destroy just one?

In my game, I’m trying to make it so the key door goes away if you have a key. But instead of just destroying the door you were touching, it destroys all doors. Any help? Sorry if behaviors are messy.

@“Biscuit Butter” Try this:

This will make it so the player has to collide with the door to destroy it, and only one door at a time.

Well that was way simpler than I thought. Thanks!
