How to completely reset an ARKit scene in Unity

Hey guys I'm having a small issue with ARKit and Unity.

In the game that I'm making I'm reloading my scene when the player dies, however when the scene is reloaded all the GameObjects are still in the same position from the last session. I want all my objects to return to their starting positions when the scene is reloaded.

I saw that some variables regarding position and rotation are marked as "static" in the code. I tried changing them but I got a lot of compile errors.

Does anyone know a way around this?

Create this method and call it whenever you want to reset the scene:

using UnityEngine.XR.iOS;
.
.
.

public void ResetScene() {
ARKitWorldTrackingSessionConfiguration sessionConfig = new ARKitWorldTrackingSessionConfiguration ( UnityARAlignment.UnityARAlignmentGravity, UnityARPlaneDetection.Horizontal);
        UnityARSessionNativeInterface.GetARSessionNativeInterface().RunWithConfigAndOptions(sessionConfig, UnityARSessionRunOption.ARSessionRunOptionRemoveExistingAnchors | UnityARSessionRunOption.ARSessionRunOptionResetTracking);
}

I found the solution!

Add these lines of code in your ARCameraManager script in the "!UnityEditor" part.

UnityARSessionRunOption options = new UnityARSessionRunOption();
options = UnityARSessionRunOption.ARSessionRunOptionRemoveExistingAnchors | UnityARSessionRunOption.ARSessionRunOptionResetTracking;
m_session.RunWithConfigAndOptions(config, options);

Now every time you reload your scene all AR elements (planes, anchors, camera tracking data) are reset.
