Controller Connection in the Scene
The Door Blueprints and the Player Controller are connected through the BPI_Doors_Interaction blueprint interface. The interface has no code in it. It just routes one actor to another actor with empty functions. Blueprints / Other / BP_DoorController
Interaction
The controller calls the Interact function in all blueprints with the same interface if the [R] key is clicked.
The door blueprints then check if the player is within the trigger box and open the door.
Variation
The keys [1] to [6] will call the Set Variation function and send the tag and choice ID to any blueprint that has the blueprint interface assigned.
The blueprints with the interface then look at the tag name and set the choice if the tag name is the correct one.
