“… are trying to do is add the ACharacter actor to a TArray contained inside of another actor object of class AActor?” Yes. But even if i tried to get reference to variable(like float or what) inside AActor from ACharacter, I make editor crashes because i dont even know how to do that. What else can I say is that, I dont have programming in c++ since while so it could be my mistake, this project Im working on is kind of try to get used to c++ again. But really i dont have any problem since yet, this is the first one.
