Many games involve directional playermovement without strafing. Instead we see character models rotating to face the direction of the input and move in that direction. In this script I incorporate the simple Move script within character controller and I added additional code to rotate the character model towards the direction of input.

    void Update () 
    {

       CharacterController controller = GetComponent<CharacterController>();

       if (controller.isGrounded) { //If we're on the ground

       if(movementEnabled) //When we're allowed to move
         {
            moveDirection = new Vector3(Input.GetAxis("Left/Right"), 0, Input.GetAxis("Down/Up"));
            moveDirection = transform.TransformDirection(moveDirection);
            moveDirection *= skateSpeed;


 transform.rotation *= Quaternion.AngleAxis(new Vector3(Input.GetAxis("Left/Right"), 0, 0));

Currently the transform.rotation has the error " No overload for method AngleAxis' takes1' arguments". However, it is still unclear to me for how to use quaternion for this commonly used method of player movement.

Thanks for the help!
