Okay, I’ve managed to figure out how to set up the Map - Enum and Boolean together - but do I have to create that again in order to use it in the Interact function of my Door_BP and again for the FirstPersonCharacter_BP? The guide you’ve linked does it all within the same Blueprint, so it shows up as a useable variable. In your screenshots it shows up and is used in the three different Blueprints. I’ve noticed you have a section on the left that says Interfaces and you have the Interact function in there. But I’m not sure how you get that.
