Rotating an object with touch

Questions & Answers
1

hi , I was looking for a way to rotate an object on my android app . I found a helpful video on youtube with this script . the script works right except I need to comment out the raycasting condition , it doesn’t work with raycasting and so the object rotates by touching anywhere on the screen and not just by touching the object . do you see anything wrong or have any suggestions on how to make it work with raycasting? tnx . here’s the code :

var targetItem : GameObject;
var GUICamera : Camera;
var ambient : GameObject;


/********Rotation Variables*********/
var rotationRate : float = 1.0;
private var wasRotating;

/************Scrolling inertia variables************/
private var scrollPosition : Vector2 = Vector2.zero;
private var scrollVelocity : float = 0;
private var timeTouchPhaseEnded: float;
private var inertiaDuration : float = 0.5f;

private var itemInertiaDuration : float = 1.0f;
private var itemTimeTouchPhaseEnded: float;
private var rotateVelocityX : float = 0;
private var rotateVelocityY : float = 0;


var hit: RaycastHit;

private var layerMask = (1 <<  8) | (1 << 2);
//private var layerMask = (1 <<  0);


function Start()
{
	layerMask =~ layerMask;	
}

function FixedUpdate()
{
	
	if (Input.touchCount > 0) 
	{		//	If there are touches...
			var theTouch : Touch = Input.GetTouch(0);		//	Cache Touch (0)
			
			var ray = Camera.main.ScreenPointToRay(theTouch.position);
			var GUIRayq = GUICamera.ScreenPointToRay(theTouch.position);
			
				
         	if(Physics.Raycast(ray,hit,50,layerMask))
         	{	

            	if(Input.touchCount == 1)
						{
							
							if (theTouch.phase == TouchPhase.Began) 
         					{
         						wasRotating = false;	
         					}		
         					
         					if (theTouch.phase == TouchPhase.Moved) 
         					{
          		        		
         						targetItem.transform.Rotate(0, theTouch.deltaPosition.x * rotationRate,0,Space.World);
         						wasRotating = true;
         					}		
         	
			}

thanks for all answers and responds :smiley: the problem was this line :

var GUIRayq = GUICamera.ScreenPointToRay(theTouch.position);

if I comment out this line the script will work , cause I hadn’t assigned it and the script would stop at that line .
