first person mouse look

as a standard first person game, when you move the mouse in a direction (besides up and down) the character moves in the direction you rotated to. i added the mouse look script but all it does is rotate the camera, not the char. what do i have to add to it to make the char move in the direction the mouse is looking towards?

this wil learn you how to make a simple fps. this is the fist thing i ever made in unity. it is very basic but you wil learn the basics quite fast.
