Original Question:I want to move my GUI joy stick in a perfect circle, not exceeding defined distance. Here is my code so far, that obviously doesn't work. How can I modify this to rotate the joy stick position along an arc of defined distance?
Updated Question:
I have updated my code to where the joy stick moves around a circle. However I would like to achieve the same outcome with less code.
var joyStick:Texture; //defined in inspector
var joyRect:Rect; //defined in inspector
var maxDist:float; //defined in inspector
private var joyCenter:Vector2;
function Start(){
joyCenter = joyRect.center;
}
function OnGUI(){
var event:Event = Event.current;
if(Input.GetKey(KeyCode.Mouse0)){
var mousePos:Vector2 = event.mousePosition;
var horDist:float = Mathf.Pow(mousePos.x-joyCenter.x, 2);
var vertDist:float = Mathf.Pow(mousePos.y-joyCenter.y, 2);
var dist:float = Mathf.Sqrt(horDist+vertDist);
if(dist
