Swipe gesture - unable to measure distance

Hello.

I've been having a bit of a problem in my attempt to create proper swipe controls.

This is my script:

 var minTouchDistance    : float        = 500;

function Start () { }

function Update () {

if (Input.touchCount > 0){ var touch = Input.touches[0]; switch (touch.phase){

 case TouchPhase.Began:
 print("wow, stepping into a new world");
 var touchPosition = touch.position;
 break;
 
 case TouchPhase.Moved:
 print("Just Cruisin");
 break;
 
 case TouchPhase.Ended:
 var endPosition = touch.position;
 var totalDistance = (touchPosition - endPosition).magnitude;
 print(touchPosition+" " +endPosition+ " " +totalDistance+ " " + touch.position);
 
 if(totalDistance > minTouchDistance){
         //Do stuff
     }
 print("noooo ! don't untouch meh !");


 break;
 }
 }
 

}

I realise this script is unfinished, but for now I just want the swiping itself to actuallyw ork - The early print, where I print multiple values, was an attempt to locate the problem. It seems that my original touch position in the "began" case, always returns 0. Which is very weird, while the second value returns the vector 2 value on screen which is fine. But if value 1 is zero at all times, it doesn't seem possible to measure the distance the user has moved from the original point since the original point, no matter where it is, is 0.

Thanks for taking the time to read this, and possibly help me with this issue :)
