GetAllPlanes() proper usage

Hi.

I'm having trouble figuring out the proper way to use ARPlaneManager.GetAllPlanes().

I need to collect the position of the AR Planes in my scene. More specific I need to update an output position that I need for object placement.

I've pasted my update function below. When I run this on m device the currentPlanes.count keeps printing 0.

Code (CSharp):

1. private void Update()
2.     {
3.         if (planeDetectionIsLive)
4.         {
5.             arPlaneManager.GetAllPlanes(currentPlanes);
6.             Debug.Log("Plane Count: " + currentPlanes.Count);
7.  
8.             if (currentPlanes.Count > detectedPlanesCount)
9.             {
10.                 if (!planeIsDetected)
11.                 {
12.                     planeIsDetected = true;
13.                 }
14.  
15.                 // Set plane position to last plane in currentPlanes
16.                 planePosition = currentPlanes[-1].transform.position;
17.  
18.                 detectedPlanesCount = currentPlanes.Count;
19.  
20.                 Debug.Log("New plane is detected, amount of planes: " + detectedPlanesCount);
21.  
22.             }
23.         }
24.     }
25.  

 

I have a similar problem with the planeAdded, planeUpdated and planeRemoved events. They are never called.

Code (CSharp):

1. public void StartPlaneDetection()
2.     {
3.         if (arPlaneManager == null)
4.         {
5.             arPlaneManager = AR_SESSION_ORIGIN.GetComponent<ARPlaneManager>();
6.         }
7.  
8.         arPlaneManager.enabled = true;
9.         planeDetectionIsLive = true;
10.  
11.         arPlaneManager.planeAdded += ArPlaneManager_PlaneAdded;
12.  
13.         Debug.Log("Start AR Plane Detection");
14.  
15.     }
16.  
17.     void ArPlaneManager_PlaneAdded(ARPlaneAddedEventArgs obj)
18.     {
19.         Debug.Log("Plane is added with y pos: " + obj.plane.transform.position.y);
20.     }
21.  

 

I'm going to guess that GetAllPlanes is from an old version of AR Foundation. I believe to manipulate planes, it's best to use the Enumeration function here: https://docs.unity3d.com/Packages/c...rackable-managers.html#enumerating-trackables
