How to set up two character controllers on one client?

I am making a 2D fighting game when both players play on the same machine. I have 1 controller working easy, but how do I set up the second one, so that one characters checks the WASD for movement, while the other checks the arrow keys?

Thanks a lot!

You should not use Input.GetAxis but Input.GetKey instead, e.g.:

Input.GetKey (KeyCode.UpArrow) for player one and Input.GetKey (KeyCode.W) for player two.

(Input.GetAxis is by default mapped in the Input Manager to the WASD and Arrow buttons.)
