Thanks!
I’m almost at my goal now. I went back and redid everything in a new way. I have gotten the harvest event to work, but unfortunately only on Actor Collission (see video). So right now it starts the harvest event when my character physically touches the Harvest Actor, how can I easiest make this happen on key input.
Is it possible to Fire a SphereTrace that activates “Event OnHit”?
I tried by just adding a Key Input (when pressed) but this would no activate branch 1 on screenshot (is it because its not in my BP_PlayerCharacter?
Whats the easiest way for me to press a key and execute the first branch in the screenshot (highlighted in blue) in the other actor? 
My player character is called BP_PlayerCharacter and I’m trying to activate a function in BP_Harvest_Actor
I’m sooooo close now!!!
