Rotate on drag for IOS?

Question

Hello all, I am new to Unity and JS so bear with me.. I'm trying to change a rotate script so that it will run on an IOS device, but having a little trouble. The script I have been using to rotate an object on my computer,

 var verticalSpeed : float = 2.0;
 var horozontalSpeed : float = 2.0;
 var depth : float = 2.0;
 
 function OnMouseDrag () {
     var v : float = verticalSpeed * Input.GetAxis ("Mouse Y");
     transform.Rotate ( -v, 0, 0);
     var h : float = horozontalSpeed * Input.GetAxis ("Mouse X");
     transform.Rotate (0, 0, h);
 }

My attempt at the IOS script,

 var verticalSpeed : float = 2.0;
 var horozontalSpeed : float = 2.0;
 var mouseDown : boolean;
 
 function update (){
     if(Input.GetMouseButton(0)){
         mouseDown = true;
     }
     else{
         mouseDown = false;
     }
     if(mouseDown){
         drag();
     }
 }
 
 function drag () {
     var v : float = verticalSpeed * Input.GetAxis ("Mouse Y");
     transform.Rotate ( -v, 0, 0);
     var h : float = horozontalSpeed * Input.GetAxis ("Mouse X");
     transform.Rotate (0, 0, h);
 }

Am I even close haha? Any ideas how I might be able to get this too work would be greatly appreciated. Thanks, Garrett.

You need to look into the Input states for iOS, using touch is a bit different to mouse.

http://docs.unity3d.com/Documentation/ScriptReference/Input-touches.html

http://docs.unity3d.com/Documentation/ScriptReference/Touch.html

http://docs.unity3d.com/Documentation/ScriptReference/TouchPhase.html

(btw your Update is with a lower u)

To modify the Update for touch, something like :

 #pragma strict
 
 private var h : float;
 private var v : float;
 private var horozontalSpeed : float = 2.0;
 private var verticalSpeed : float = 2.0;
 
 function Update()
 {
     if (Input.touchCount == 1)
     {
         var touch : Touch = Input.GetTouch(0);
         
         if (touch.phase == TouchPhase.Moved)
         {
             h = horozontalSpeed * touch.deltaPosition.x ;
             transform.Rotate( 0, -h, 0, Space.World );
             
             v = verticalSpeed * touch.deltaPosition.y ;
             transform.Rotate( v, 0, 0, Space.World );
         }
     }
 }

here's some sample script I posted in the forums : http://forum.unity3d.com/threads/142758-Moving-objects-with-your-finger
