Hi, first check if Fire method is actually bound to a left mouse button, and try to increase time in debug screen message.

Hi! Yes, it is bound, added a screenshot. And increased time but can’t see the message. The method OpenCloseDoor are don’t calls by some reason

I remembered that SetupPlayerInputComponent only works with a player controller. If you set your door as default pawn then it should work.

I don’t think that is your intention to play as a door, so you need in your player controller pawn setup input component and call door open method from it

I would suggest you to do line trace here to see if nothing is coming in between. Setup Input Component is needed when you are getting the input for the player pawn or controller, don’t use that way here.
