In Unity Arkit,how to show a text in UnityARHitTestExample scene until a vertical plane is found?

I am trying to show a text say "Scan for a surface" until it scans a plane surface.Once the device detects a plane surface the message should disappear and add another text.Where should I write code for this purpose.I found two instances where prefab plane is initialised ,one in UnityARGeneratePlane.cs and UnityARUtility.cs .I added a Gameobject as Text in UnityARGeneratePlane.cs and used setactive to true and false to show and hide the text.It is showing when i used it in the start method.How to hide the text is where i struggle.Where to use the code to hide the text when a plane is detected?Is it in UnityARGeneratePlane.cs or UnityARUtility.cs.

 

Hi @zyonneo ,

You would just have a GameObject with a script that does something like this:

Code (CSharp):

1. public class MyClass : MonoBehaviour
2. {
3.     // Use this for initialization
4.     void Start()
5.     {
6.         Debug.Log("waiting for first anchor");
7.         UnityARSessionNativeInterface.ARAnchorAddedEvent += AddAnchor;
8.     }
9.  
10.     void AddAnchor(ARPlaneAnchor arPlaneAnchor)
11.     {
12.         Debug.Log("added first anchor");
13.         UnityARSessionNativeInterface.ARAnchorAddedEvent -= AddAnchor;
14.     }
15. }
16.
