Hi, I do not own the TPS Starter Pack. So it’s going to be a bit difficult to say what exactly prevents it’s AI from registering the player character. But the first place I’d suggest looking at would be the class responsible for tracking down the player. If the said AI uses Unreal Engine’s native AI Perception, you would have to register the tower defense player character as a stimulus source so that it can be perceived by the AI bots. If it’s using a custom threat detection system, then it would require adding the player character to it’s list of potential targets.
