OK so I am completely new to UE4 and game development for that matter. I have a variable from another blueprint, that I bound to an actor. I want to import that into several other blueprints, which I have accomplished with getAllActorsOfClass. But when I try to set a variable from that actor, i need a reference to that actor? I dont know what im meant to put there. Screenshot below
Yes, the variable that you are Setting needs to know what specific actor the variable is attached to. If you are Setting within the actor that owns the variable, that reference would be Self. If you are Setting a variable in another actor, you need a reference to that actor that owns the variable. When you GetAllActorsOfClass, you are presented with an array of actors. One or all of those actors would be the reference actor that would plug into the reference of the Set node. (If more than one actor in the array, you will have to Loop through each actor in the array).
