I’m trying to have a blueprint execute a function that the other blueprint can register. But the other blueprint actor is also being created by the first blueprint. How can I have the first blueprint get reference to the instance it is creating and tell it to execute event in it (with a string parameter attached too)?
When you spawn the “blueprint actor” drag off the return pin and search for whatever your function within the created BP is called that you want to execute. You should be able to call it from the creating BP that way.
