this is my script in this i want to simple camera walk through using andriod

#pragma strict

function Start () {

}

function Update () {

//------------------Code for Zooming Out------------

if (Input.GetAxis(“Mouse ScrollWheel”) <0)

   {

if (Camera.main.fieldOfView<=100)

Camera.main.fieldOfView +=2;

if (Camera.main.orthographicSize<=20)

                               Camera.main.orthographicSize +=0.5;

   }

//----------------Code for Zooming In-----------------------

if (Input.GetAxis("Mouse ScrollWheel") > 0)

   {

if (Camera.main.fieldOfView>2)

Camera.main.fieldOfView -=2;

if (Camera.main.orthographicSize>=1)

                            Camera.main.orthographicSize -=0.5;

   }

//-------Code to switch camera between Perspective and Orthographic--------
if (Input.GetKeyDown(“down”))

{

if(Camera.main.transform.localPosition.x>-3&&Camera.main.transform.localPosition.x<=3){
Camera.main.transform.localPosition.x -=.1;
}

}

 if (Input.GetKeyDown("up"))

{

if(Camera.main.transform.localPosition.x>=-3&&Camera.main.transform.localPosition.x<3){
Camera.main.transform.localPosition.x +=.1;
}

}

 if (Input.GetKeyDown("left"))

{
if(Camera.main.transform.localPosition.z>=11&&Camera.main.transform.localPosition.z<16){
Camera.main.transform.localPosition.z +=.1;
}

}
if (Input.GetKeyDown(“right”))

{
if(Camera.main.transform.localPosition.z>11&&Camera.main.transform.localPosition.z<=16){
Camera.main.transform.localPosition.z -=.1;
}

}

}

Check out the documentation for advice about using the touch screen on mobile devices. And try this code:

function OnGUI() {
	GUI.Label (Rect (10, 10, 100, 35), "Touches");
	for (var i : int = 0; i < Input.touchCount; ++i) {
		var t : Touch = Input.GetTouch(i);
		var p : Vector2 = t.position;
		GUI.Label (Rect (10, 35*(i+1), 500, 35), "Touch " + i + ": (" + p.x + ", " + p.y + "){"+ t.fingerId+"}" + t.phase);
	}
}

That should allow you to see the touches, their positions etc as you touch the screen.
