Question
Movement relies on transform.basis’s basis. therefore making a mouse-based visual navigation in yaw rotation cause a axis-based strafing that’s reverse-relative to player’s movement input.
I don’t know what to do from here, it took hours to do something I want but if it comes out to this, should I declare this algorithm as unusable?
