UnityException: Index out of bounds. Tried everything, any ideas why?

Hey, so how should i fix this error? "UnityException: Index out of bounds" ive tried using:

Code (csharp):

1. if(Input.touchCount > 0)
2. {
3. //My code
4. }

But it doesnt seem to work. Any ideas? The specific line that i get an error on is this one:

Code (csharp):

1.  
2.             float x = Input.GetTouch (touch2Watch).position.x / Screen.width,
3.  

-Thanks!

Full code:

Code (csharp):

1.  
2. Vector3 MoveJoyStick()
3.     {
4.         if(Input.touchCount > 0)
5.         {
6.             float x = Input.GetTouch (touch2Watch).position.x / Screen.width,
7.             y = Input.GetTouch (touch2Watch).position.y / Screen.height;
8.             position = Vector3.ClampMagnitude(new Vector3 (x-oJoyPos.x, y-oJoyPos.y, 0), maxJoyDelta) + oJoyPos;
9.    
10.             joyDelta = new Vector3(position.x - oJoyPos.x, position.y - oJoyPos.y, 0);
11.         }
12.             return position;
13.     }

 

Whats the value of touch2Watch
Presumably its greater than the number of touches

 

Its the maximum amount of touches.

 

The number in GetTouch can't be equal to or greater than the current number of touches. If touchCount > 0, then it could be as low as 1, which would mean only GetTouch(0) would work, and anything higher is out of bounds. You must always check for the current number of touches before using GetTouch.

Yeah, fixed it.

Code (csharp):

1.  
2. if(Input.touchCount > touch2Watch || Input.touchCount > touch2Watch)
3.         {
4.             float x = Input.GetTouch (touch2Watch).position.x / Screen.width,
5.             y = Input.GetTouch (touch2Watch).position.y / Screen.height;
6.            
7.             Vposition = Vector3.ClampMagnitude(new Vector3 (x-oJoyPos.x, y-oJoyPos.y, 0), maxJoyDelta) + oJoyPos;
8.            
9.            
10.             joyDelta = new Vector3(Vposition.x - oJoyPos.x, Vposition.y - oJoyPos.y, 0);
11.         }

 

This seems redundant:

This seems redundant.

 

Yeah, i guess so because you cant see the rest of the script. Im not gonna bother copying that and showing to you, but thanks for the help guys!
