Detecting tag on Android Hittest.

Questions & Answers
1

The code Im using is working fine, but I have to assign the script to every GUItexture I want to use as a button. I’m overhauling my entire menu system, so I want to simplify everything by just attaching this script once to an empty gameobject, then on hittest, look for tag, then run if statements to direct the flow from there. Such as

if(****.tag == "Chapter1"){
*Go to chapter 1 level select*
}
if(*****.tag == "Chapter 2"){ etc...

But I don’t know how to detect tag on hittest. If it’s even possible. Here is the code Im using now.

#pragma strict

var startButton : GUITexture;
public var deleteSave : boolean = false;
public var Chapter : int;

function Start () {
startButton.color.a = 0.0f;
yield WaitForSeconds(2);
        yield Fade(0.0, 1.0, 2.0);     // fade up
      //  yield Fade(1.0, 0.0, 2.0);     // fade down
    }

function Update () 
{
AutoResize(Screen.width, Screen.height);
if(deleteSave==true){ 
PlayerPrefs.DeleteAll();
deleteSave=false;
}
       for (var i = 0; i < Input.touchCount; ++i)
       {
            if(startButton.HitTest(Input.GetTouch(i).position)){
                   if (Input.GetTouch(i).phase == TouchPhase.Began) 
               {
                        if(Input.GetTouch(i).tapCount == 1)
                        {
                        if(Chapter==1){
                       
                          }
                 
                          
                        }
               }
       }
       }
       
      
}

public static function AutoResize(screenWidth:int, screenHeight:int):void
{
    var resizeRatio:Vector2 = Vector2(Screen.width / parseFloat(screenWidth), Screen.height / parseFloat(screenHeight));
    GUI.matrix = Matrix4x4.TRS(Vector3.zero, Quaternion.identity, Vector3(resizeRatio.x, resizeRatio.y, 1.0));
}
     
    
     
    function Fade (startLevel :float, endLevel :float, duration :float) {
        var speed : float = 0.5/duration;  
        for (var t :float = 0.0; t < 1.0; t += Time.deltaTime*speed) {
            startButton.color.a = Mathf.Lerp(startLevel, endLevel, t);
            yield;
        }
    }

In order to rewrite the code the way you describe, you will need an array of guiTexture object to test. You can create that list by dragging and dropping into a public array, or you can tag them all the same and use GameObject.FindGameObjectsWithTag(). So say your array is called ‘uiElements’. If the elements are GUITextures, your code will have:

Touch t = Input.GetTouch(i);
if (t.phase == TouchPhaseBegin && uiElemens*.HitTest(t.position) {*

Debug.Log("You hit " + uiElements*.name;*
}
If you collected them using FindGameObjectsWithTag(), you will have an array of game object, and your test might look like:
Touch t = Input.GetTouch(i);
if (t.phase == TouchPhaseBegin && uiElemensguiTexture.HitTest(t.position) {
Debug.Log("You hit " + uiElements*.name;*
}
