trouble with input.touches

hi everybody, i have some trouble with properly identifying touches on tablet.
basically i need to have just one tap, tap hold and rotate (or slide) and slide with two fingers...

the code i have works fine for slide with two fingers. it works when i want to rotate camera
but when i lift the finger if object is below the finger it will get selected. i want to avoid this

here is the code:

Code (csharp):

1. //IF WE HAVE TWO TOUCHES AND WE HAVE MOVEMENT OF BOTH OF THEM
2.     if(Input.touchCount>1  Input.GetTouch(0).phase == TouchPhase.Moved  Input.GetTouch(1).phase == TouchPhase.Moved){
3.    
4.         distance += Input.GetTouch(0).deltaPosition.y*0.01;
5.    
6.     //IF WE HAVE ONE TOUCH AND WE  HAVE MOVEMENT
7.     }
8.    
9.     if(Input.touchCount == 1  Input.GetTouch(0).phase == TouchPhase.Moved) {
10.    
11.         touchDeltaPosition = Input.GetTouch(0).deltaPosition;
12.        
13.         x += touchDeltaPosition.x * xSpeed*0.003;
14.         y -= touchDeltaPosition.y * ySpeed*0.003;
15.        
16.     }
17.    
18.     //IF WE HAVE JUST ONE CLICK
19.     if(Input.touchCount == 1  Input.GetTouch(0).phase == TouchPhase.Ended){
20.    
21.         var hit : RaycastHit;
22.            
23.         //CHECK IF WE HIT SOMETHING WITH RAY FROM THE TOUCH POSITION TO INFINITY
24.         if(Physics.Raycast(Camera.main.ScreenPointToRay(Input.GetTouch(0).position),hit,100)){
25.                    
26.             //DO SOMETHING
27.  
28.         }
29.        
30.     }
31.    

any ides appreciated!

 

Could you possibly add the objects you don;t want selected to a list of sorts and then disregard them if one of them is hit... or just make it so that your ray-cast does not look at those objects at all?
