David, you could arrange the script?

Contact me via PM and I'll give you an email to send your project to. 

ok, your email please.

Let's try to consolidate these posts - can you PM me a link to your project?

i put this default script to the (teapot) 3d obj. But wont let the aplication to run.

the script is attach to the GUItexture.button.

here the script. name b2.js

______________________________________

var My_Texture : GUITexture;

var myObject : GameObject;

var myName : String = "teapot";

function Start(){

  myObject = GameObject.Find(myName);

}

function Update () 

{

if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)

{

if (My_Texture.HitTest(Input.GetTouch(0).position))

{

myObject.renderer.enabled = !myObject.renderer.enabled;

}

}

}

You need to set the isTracking boolean from your OnTrackingFound/Lost methods in the event handler. If this script is attached to the same object you can reference it using GetComponent, see: http://docs.unity3d.com/Documentation/ScriptReference/GameObject.GetComponent.html

If the script is on another object, like the ARCamera, you'll first need to obtain that object using GameObject.Find('obj_name');]

Once you have the component reference, set the isTracking boolean to true in OnTrackingFound and false in OnTrackingLost.

here the code with the new insert lines. But the GUITexture.button still showing the Object outside the image target if i touch.

var isTracking : boolean;

var myObject : GameObject;

var myName : String = "teapot";

function Start(){

  myObject = GameObject.Find(myName);

}

function Update () {

if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began){

//    if (guiTexture.HitTest(Input.GetTouch(0).position)){

//        myObject.renderer.enabled = !myObject.renderer.enabled;

      if (guiTexture.HitTest(Input.GetTouch(0).position) && isTracking ){

      myObject.renderer.enabled = !myObject.renderer.enabled;

        }

    }

}

how can be fix

I would add a public variable that's set from the OnTrackingFound method of your target and accessed via GetComponent().

e.g.

var isTracking : Boolean

then check this before enabling the renderer..

if (guiTexture.HitTest(Input.GetTouch(0).position) && isTracking ){

myObject.renderer.enabled = !myObject.renderer.enabled;

}
