I have this problem with my bluetooth controller ( it's the game sir G3) where it's difficult to map the camera controls to the analog stick ( left stick and right stick). First off, when mapping the controller, pressing left on the analog stick made the camera turn right and pressing right made the camera turn left. I fixed this by swapping the left and right control mappings. The big problem is that if you map the camera controls where Right = Left, Left = Right, Up = Up, and Down = Down, which is what you would expect to work, but the camera will be completely messed up completely, depending on the order you mapped them in. For instance, if you map left first, the controls will be as follows. left = left and down, right = right and down, up = up and right, and down = down and right. Also a bizarre thing that happens is that diagonal movement overrides this issue, for instance, up and left = up and left, down and right = down and right, and vice versa. Also the camera can only move in eight directions, and i'm not sure if it's supposed to be analog.
also it works fine if maped to anything else
