How to make all this information displayed on the screen only after scanning the image and it should not go from that until I want to hide that from the screen?

Question

I want to make all this information displayed on the screen only after scanning the image and it should not go from that until I want to hide that from the screen.

Answer 1

Ok so once you scan it, it will appear and then you want it to disappear on a defined function?

From the image target, remove the Default trackable event handler script and attach this script.
Default trackable event handler script

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class Tracker : DefaultTrackableEventHandler

{

    override protected void Start()

    {

        base.Start();

    }

    override protected void OnTrackingFound()

    {

//Turn on the mesh renderer

 

    }

    protected override void OnTrackingLost()

    {

//turn off the mesh renderer

    }

 

}
