no not really, I thought of doing it that way but what I am having an issue with right now is that every time the marble bumps something it makes the camera shake. Example: if I am jumping the marble up stairs, when it hits the back of the stair it swings the camera.
I guess I am asking sine W,S,A,D move the marble can we lock them to the only buttons that move the camera and not when the marble collides with environments , otherwise I fear it will make the player sick if the camera jumps on ever little touch or jump.
