Coding for touches...performance question

Unity Engine

Well, i´m looking for a way to save performance for my game…

i have this code:

function Update () {

if (Input.touches.Length > 0){

	for (var r : int = 0; r < Input.touchCount; r++){
	
		if (this.guiTexture.HitTest(Input.GetTouch(r).position)){
		
			if (Input.GetTouch(r).phase == TouchPhase.Began)	Debug.Log("A");
			else if (Input.GetTouch(r).phase == TouchPhase.Ended)	Debug.Log("B");
			}
		
		}
	}
}

i put it on each guiTexture used to be a touch button…

i just was curious if i have 4 touches button, then this script will be instanced 4 times, if it contents Update function, i can imagine that this will not be a good idea to get a better performance.

What do you think if i just use a general script aiming to each touchButton ?

for instance:

private var touchBtn : GUITexture[];

function Awake () {
touchBtn = new GUITexture[4];
for (var g : int = 0; g <= 3; g++)  touchBtn[g] = GameObject.Find("GUI/button" + g.ToString());
}


function Update () {

if (Input.touches.Length > 0){

	for (var r : int = 0; r < Input.touchCount; r++){
	
                //If button 0 is touched
		if (touchBtn[0].HitTest(Input.GetTouch(r).position)){
		
			if (Input.GetTouch(r).phase == TouchPhase.Began)	//Do things for Button 0
			}

                 else if (touchBtn[1].HitTest(Input.GetTouch(r).position)){

                         if (Input.GetTouch(r).phase == TouchPhase.Began) //Do things for Button 1
                         }
                       
                   //... and so... until finish button [3]
		
		 }
	}
}

This script will be instanced just one time on a root gameObject…
will this help me to gain performance?..

Thanks.

Use the profiler for that (you can test with e.g. 50 on screen buttons). And I would doubt that touch handling causes any noticeable performance issues.

Yes Agent 007, the touch does not cause a bit performance issue, but i was talking about update function… it will be instanced 4 times… no matter?
