dynamic joysticks solution?

Questions & Answers
1

I’m sorry I’m creating a post here for this but I just can’t seem to find anyone who has an actual answer, so i’m trying a fresh question:
Is there anyone who has managed to make the dynamic joystick thing happen?
I have managed to modify the original standard (mobile) kit code shipped with unity so that it places the joystick where i put my finger. Trouble is that it only puts the graphic there. The joystick’s ZERO is always at the x,y=zero of the screen. e.g. anywhere i click, my joystick points up+right.

Any ideas?

Thanks in advance.

Posting my solution here:
joystick.js to be attached to the joystick object

#pragma strict 

var thumb : GUITexture; 
var base : GUITexture;
var origin : Vector2;
var baseWidth : int;
var baseHeight : int; 
var position : Vector2;

var fadeInRight : boolean;  
var JoyID : int;
static  var joysticks : Joystick[];					// A static collection of all joysticks

	thumb = GetComponent(GUITexture);
	baseWidth = base.pixelInset.width; 
	baseHeight = base.pixelInset.height;  
}

	if(fadeInLeft){ 
	gameObject.Find("LeftBase").GetComponent(GUITexture).color.a=Mathf.Lerp(gameObject.Find("LeftBase").GetComponent(GUITexture).color.a,1.0,Time.deltaTime*8);
