Question
I’ve been testing controller input in a 3d player movement test I’m doing, and I just realized that it doesn’t work as intended when the camera is on top of the character (kinda like a bird view). When looking from that view, the character moves to the right when pressing up and/or down. the right and left inputs still work fine with the controller. I’m just having this issue with my controller and I don’t understand why.
At first, I thought it was something I did in “project settings → inputs”, but I couldn’t find anything related to the mouse or the Joypad 2 (right joystick). I then looked around and decided to add some camera input related to the right joystick, but it still gave me the input error. What am I missing?
