You are right that it could create some issues - but nothing that cant be solved easily. You could just have a variable that keeps track of whether the door is open or closed so the player doesn’t open a door while its already open. In the end I think we need more information from Roginich on what exactly does he want.
@Roginich, do you want the door to open on proximity? Do you want the player to face the door and press a button? There are many different ways to get this working based on your design
