Note: i disable activity button write Button1,Button2 and write script in 3d object under image target

 public GameObject Button1;
 public GameObject Button2;


 // Use this for initialization
 void Start () {
     Button1.SetActive(true);
     Button2.SetActive(true);

 }
 
 // Update is called once per frame
 void Update () {
     
 }

}

@CSH92 I didn't get your question Exactly, As per i understood

-Basically in Vuforia Image Target contains DefaultTrackableEventHandler script -Find OnTackingFound Function in it -You can either Instantiate or Enable/Disable Button in this function -On button click event Instantiate or Enable/Disable your Object and hide button Hope this helps

@inovotm Thank you for your reply. First, I apologize for the poor English language. Your intention is that I want the button to be called when the AR image is loaded Your answer is appreciated, but I find it difficult to approach the solution in such a way When using that function, where should the buttons be displayed and the images to be displayed? Do buttons need to be below the image target? Or does it matter where the buttons are? thank

1) OnTrackingfound you want to display one button or image or both??

2) Button should be above the image target otherwise you won't click it or see it.

I do not know what OnTracking is. What does OnTracking mean when I found this button? The button appears as soon as I launch the app I want this button to be visible after loading the object through the image target, not when launching the app Also, I did not include the canvas with buttons anywhere

I know what you mean, but can i make the DefaultTrackableEventHandler for each image target? cause when i change the script, then the whole image target will apply from this script too. For Example i want to make text "Elephant" appear when image elephant target found, but also i need the "Horse" text visible when the image target horse found.

I'm sorry I can not speak English well. In summary, i will want to see the buttons when I recognize the image and load the object into the AR
