i feel like this should be really simple. but ive watched every tutorial i can find and everytime i hit the same problem. the tast is simple. there usually something like a button and a door. which is my current problem. and i cant figure out how to get the reference. so it wont work.
my ultimate goal that i need to move forward is widget contolling the door. im kinda going for a mission door where i can select a level. and the level streams in behind the door and then it opens. ive got the streaming figured out. but i cant get the door to open. because i cant figure out how to get the reference. and my biggest frustration is how everybody tells me the use get all actors of class. then tell me shortly after that i should never use it in a real game because of how expensive it is, and that there are more proper ways to do it. but nobody will every say the proper method.
can someone please help me
