I wona to move a cube with rotate,So that the move is due to the rotation.
like this image:

my code is :

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour {
	
	
	public float speed = 6.0F;
    public float jumpSpeed = 8.0F;
    public float gravity = 20.0F;
    private Vector3 moveDirection = Vector3.zero;
	
	// Use this for initialization
	void Start () {
	
	}
    void Update() {
        CharacterController controller = GetComponent<CharacterController>();
        if (controller.isGrounded) {
			float mv = Input.GetAxis("Horizontal");
			transform.Rotate(Vector3.forward,-mv);
            moveDirection = new Vector3(mv* Time.deltaTime, mv* Time.deltaTime, 0);
            moveDirection = transform.TransformDirection(moveDirection);
            moveDirection *= speed;
            if (Input.GetButton("Jump"))
                moveDirection.y = jumpSpeed;
            
        }
        moveDirection.y -= gravity * Time.deltaTime;
        controller.Move(moveDirection * Time.deltaTime);
    }
}

how I can do it?
when when player has been rotate the Axis is not work move to forward.

Here is a bit of source that, using a Rigidbody, will roll a cube across a plane using the arrow keys. To Use:

  • Create a plane
  • Put a cube on top of the plane
  • Add a Rigidbody to the plane
  • Add the script

`

#pragma strict

private var forceAmount = 40.0;
private var rotationSpeed = 45.0;

function FixedUpdate() {
	transform.Rotate(0.0, rotationSpeed * Time.fixedDeltaTime * Input.GetAxis("Horizontal"), 0.0, Space.World);
 	rigidbody.AddRelativeTorque(Vector3(forceAmount * Input.GetAxis("Vertical"), 0.0, 0.0));
}

`

Note I had “Horizontal” and “Vertical” setup to use keys, not a joystick or mouse movement when I ran a brief test of this code. For general use, more code would be needed to address specific issues with the interaction of the cube and the physical environment.
