Hello @DevKaiUnreal , from what you wrote, i suposse you want to recive a notification when the movement is completed. I think this thread will be usefull, the idea of the solution is to use a PlayerController and a AIController. The PlayerController listen to the input and send instructions to the AIController, and the AIController control your character. Other threads that may be helpfull are this and this .
I hope this is usefull (also, UAIBlueprintHelperLibrary::SimpleMoveToLocation recive a AController and a vector, and both, APlayerController and AAIController, inherit from AController, probably that is why the method can work with non-AI controller).
