Migrating from ARKit to ARFoundation problems

Hello

I'm migrating a project from ARKit to ARFoundation but I'm running into some problems:

1) What are the equivelants of:

Code (CSharp):

1. UnityARSessionNativeInterface.ARFrameUpdatedEvent += ARFrameUpdated;
2. UnityARSessionNativeInterface.ARSessionInterruptedEvent += ARWasInterrupted;

2) The AR Default Plane shows up very weirdly, kind of a stingray fish


3) I added AR Default Point Cloud to my scene: particles are nowhere to be seen?

 

OK here's my final code on the ARFoundation-version of the FocusSquare.cs. It's not As fancy (i.e. no animation for the findingsquare) but should get you going!

Code (CSharp):

1. //A FocusSquare script to be used in combination with ARFoundation 1.0
2.  
3.  
4. using System.Collections;
5. using System.Collections.Generic;
6. using UnityEngine;
7. using UnityEngine.Experimental.XR;
8. using UnityEngine.XR.ARFoundation;
9.  
10.  
11. public class FocusSquareARF : MonoBehaviour
12. {
13.  
14.     public enum FocusState { Found, Finding, Initializing };
15.     public FocusState SquareState = FocusState.Initializing;
16.     public ARSessionOrigin m_SessionOrigin;
17.     Ray ray;
18.     static List<ARRaycastHit> s_Hits = new List<ARRaycastHit>();
19.     public GameObject focusSquareFinding; //mesh of a plane as child of the gameobject this script is on, shown when no features were found.
20.     public GameObject focusSquareFound;  //mesh of a plane as child of the gameobject this script is on
21.     public TrackableType whatToTrack;
22.  
23.  
24.     void Update()
25.     {
26.         ray = Camera.main.ScreenPointToRay(new Vector3(Screen.width / 2, Screen.height / 2, 0));
27.         if (m_SessionOrigin.Raycast(ray, s_Hits, whatToTrack))
28.         {
29.             //Debug.Log("hit");
30.             Pose hitPose = s_Hits[0].pose;
31.             transform.position = hitPose.position;
32.             transform.rotation = hitPose.rotation;
33.             SquareState = FocusState.Found;
34.             focusSquareFinding.SetActive(false);
35.             focusSquareFound.SetActive(true);
36.  
37.         }
38.         else{
39.  
40.             SquareState = FocusState.Finding;
41.             focusSquareFinding.SetActive(true);
42.             focusSquareFound.SetActive(false);
43.         }
44.     }
45. }

Hi @JelmerV ,
Have you found the equivalent of UnityARSessionNativeInterface.ARFrameUpdatedEvent += ARFrameUpdated;

I couldn't find events documentation of ARFoundation.
