Making a GUI Texture tappable on iPhone

Questions & Answers
1

Disclaimer: I’ve searched everywhere for this, including the Unity documentation.

In the Unity simulator, this works fine if I add a script like this to my GUITexture in the hierarchy:

function OnMouseUp (){
		//do stuff
}

However when run on the iPhone, this doesn’t have any effect. After a bit of searching I tried:

if(Input.touchCount>0){
//do stuff
}

This doesn’t appear to do anything in the simulator or on the handset.

One thing that does work fine on the iPhone is building a GUIButton like this:

function OnGUI() {
	
    	if(GUI.Button(Rect(0,400,320,44),"I'm a code generated button!")) {
    		//do stuff		
    		}
    }

However this is code for dynamically drawing a button, not code for placing on a GUITexture game object.

Any clues? :frowning:

Actually, I fixed this by looking at some Android questions!!

Here’s the ballache answer (you need to do this per button… ):

function Update(){
	if (Input.touchCount == 1)
	{
	var touch: Touch = Input.touches[0]; 
	
	if(touch.phase == TouchPhase.Began && guiTexture.HitTest(touch.position))
	
		{
		// do amazing things
		} 
	}
}

,how do you use this with multiple touches?

Lets say you have 2 GUITextures and you want each of them to have independent touches, how do you modify the code so that you

Lets say you have 2 GUITextures and you want each of them to have independent touches, how do you modify the code so that you if you touch the 1 texture if activates, touching the other activates that one aswell and releasing either of them deactivates the one released…
Same works if they are touched independently

I have some problem, i want do something like this:

When i tap guitexture it change from texture1 to texture2, so i combine two scripts this for tap and this:

var texture1 : GUITexture;
var texture2 : GUITexture;

var someTexture : GUITexture;
someTexture = texture1;
guiTexture.texture = texture1.texture;

function Update () {
}

function OnGUI() {

    if(GUI.Button(Rect(0,0,100,40),"Cambia fondo")){
        if(someTexture == texture1) {
            someTexture = texture2;
        } else if (someTexture == texture2) {
            someTexture = texture1;
        }   

    }
}

for change GUITexture

but first what i do is check this script, it work but GUITexture are not change on screen in inspector i see changes texture1 to texture2

I want do something like this:

var texture1 : GUITexture;
var texture2 : GUITexture;

var someTexture : GUITexture;
someTexture = texture1;
guiTexture.texture = texture1.texture;


function Update(){
    if (Input.touchCount == 1)
    {
    var touch: Touch = Input.touches[0]; 

    if(touch.phase == TouchPhase.Began && guiTexture.HitTest(touch.position))

       {
        if(someTexture == texture1) {
            someTexture = texture2;
        } else if (someTexture == texture2) {
            someTexture = texture1;
        }   
       } 
    }
}

I search 2h for something and i cant find anything, so… somebody can help me?
