Since i place a Player Start in my game my AI have started bug.So I decide to remove my Player Start but my AI do same thing. I think it relates to my Event tick but i do not know more.
Your hero variable seems to be empty becasue the cast on the event begin play failed. Judging from your second screenshot the player has no Player Character. I don’t know how but maybe your player didn’t posses any pawn.
Or your player character simply is not an instance of the class “BP_remy”. Maybe you player is spawning itself another class as pawn to posses it (look into your game mode BP or world settings)
IN oyur Target Point Police function I don’t really understand the casting of the class to another class especially since it’s a constant you put in there (is this function unfinshed?). For the spawn you usually would just select a class you want to spawn.
