I also encountered this issue. In their manual Designing with Cameras and Controls, it was stated, and I quote:
-“In order for players to be able to aim their weapons and have their characters change direction, a Player Controller device is placed in the level with the default settings.”
But I still don’t understand how to add the “Player Controller” to my level. I couldn’t find it in the list of devices.
Can anyone explain how to do this?
