UI Buttons + GetTouch

Hello, everybody.

I`m developing FPS controls for my mobile game. With new GUI, I created buttons for moving my character controller forward, back, right and left. I use, for them, and Event Trigger (PointerEnter event). This works perfectly.

In the other hand, I have an script for rotate the gameobject head (this object has attached a main camera). If I detect that user is touching the half right side of the screen, I rotate the head (and its rotates the camera). This works fine too.

My problem is that both systems dosnt work at the same time. When I use one finger for moving my character, and later I use a second finger for rotate the camera, my character stops and the camera rotates (and vice versa).

More information:

Script for camera rotation (from wiki):

Code (CSharp):

1. void Update () {
2.  
3.         if ( Input.touches.Length > 0  && Input.GetTouch(0).position.x > Screen.width/2 )
4.         {
5.  
6.             if (Input.touches[0].phase == TouchPhase.Moved)
7.             {
8.                 Vector2 delta = Input.touches[0].deltaPosition;
9.                 float rotationZ = delta.x * sensitivityX * Time.deltaTime;
10.                 rotationZ = invertX ? rotationZ : rotationZ * -1;
11.                 float rotationX = delta.y * sensitivityY * Time.deltaTime;
12.                 rotationX = invertY ? rotationX : rotationX * -1;
13.                 transform.localEulerAngles += new Vector3(rotationX, rotationZ, 0);
14.             }
15.         }
16.     }

Code for move my character controller (where cc is my character controller):

Code (CSharp):

1. cc.Move(Vector3.back * Time.deltaTime * speed);

How can I do for boths systems works together.

Thanks a lot.
