roll a ball with android

i got this script for a roll a ball built forandroid device it works fine but it's all back wards so some help would be welcome

here's the script

Code (csharp):

1. var tilt : Vector3 = Vector3.zero;
2. var speed : float;
3. private var circ : float;
4. private var previousPosition : Vector3;
5.  
6. @script RequireComponent(Rigidbody)
7. function Start()
8. {
9.     //Find the circumference of the circle so that the circle can be rotated the appropriate amount when rolling
10.     circ = 2 * Mathf.PI * collider.bounds.extents.x;   
11.     previousPosition = transform.position;
12. }
13.  
14.  
15. function Update () {
16.     tilt.x = -Input.acceleration.y;
17.     tilt.z = Input.acceleration.x;
18.    
19.     rigidbody.AddForce(tilt * speed * Time.deltaTime);
20. }
21.  
22. function LateUpdate()
23. {
24.     var movement : Vector3 = transform.position - previousPosition;
25.    
26.     movement = Vector3(movement.z,0,  -movement.x);
27.    
28.     transform.Rotate(movement / circ * 360, Space.World);
29.    
30.     previousPosition = transform.position; 
31.    
32. }

 

This maybe?

Code (csharp):

1. var tilt : Vector3 = Vector3.zero;
2. var speed : float;
3. private var circ : float;
4. private var previousPosition : Vector3;
5.  
6. @script RequireComponent(Rigidbody)
7.  
8. function Start(){
9.  
10.     //Find the circumference of the circle so that the circle can be rotated the appropriate amount when rollin
11.     circ = 2 * Mathf.PI * collider.bounds.extents.x;    
12.     previousPosition = transform.position;
13. }
14.  
15. function Update () {
16.  
17.     tilt.x = Input.acceleration.y;
18.     tilt.z = -Input.acceleration.x;
19.  
20.     rigidbody.AddForce(tilt * speed * Time.deltaTime);
21. }
22.  
23. function LateUpdate(){
24.  
25.     var movement : Vector3 = transform.position - previousPosition;
26.    
27.     movement = Vector3(movement.z,0,  -movement.x);
28.     transform.Rotate(movement / circ * 360, Space.World);
29.     previousPosition = transform.position;  
30. }

 

i got it working now but id like it to work so the phone face's you not holding the phone horizontal

 

then wouldn't you just change your axes?

 

Can this be added along with the keyboard controls?
Like I already have this code as shown in the tutorial.

Code (CSharp):

1. void FixedUpdate()
2. {
3.     float moveHorizontal = Input.GetAxis ("Horizontal");
4.     float moveVertical = Input.GetAxis ("Vertical");
5.  
6.     Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);
7.     rb.AddForce (movement * speed);
8. }

Can I just add this code and it will work for both keyboard input and accelerometer input?

Code (CSharp):

1. tilt.x = Input.acceleration.y;
2. tilt.z = -Input.acceleration.x;
3. rigidbody.AddForce(tilt * speed * Time.deltaTime);
