CharacterController.SimpleMove

Description

Moves the character with speed.

Velocity along the y-axis is ignored. Speed is in units/s. Gravity is automatically applied. Returns if the character is grounded. It is recommended that you make only one call to Move or SimpleMove per frame.

var speed : float = 3.0;
var rotateSpeed : float = 3.0;

function Update () {
    var controller : CharacterController = GetComponent.<CharacterController>();

    // Rotate around y - axis
    transform.Rotate(0, Input.GetAxis ("Horizontal") * rotateSpeed, 0);

    // Move forward / backward
    var forward : Vector3 = transform.TransformDirection(Vector3.forward);
    var curSpeed : float = speed * Input.GetAxis ("Vertical");
    controller.SimpleMove(forward * curSpeed);
}
