Hi all, I'm having a weird problem where I'm trying to call the Recenterfunction. So I am currently trying to develop on the rift, and then building on the Quest. However, I am facing a problem, when I call the recenter function on the rift, everything works perfectly and as intended. However, when I test it on the Quest, the function does not seem to work at all. Does anyone have the same thing? If it matters, I'm using Unity 2018.4.0f1 LTSThanks all!

I have the same problem when developing a game player can sit to play, so the head pose recenter is every useful when loading a new scene.After digging more about those APIs, I found none of them works on my quest 2, so decide to recenter it by myself. The code is sample:1. Record the FIRST head position and rotation.2. Add a parent root for both head and hand gameobject, call it TrackingSpace.3. Set the position (Quaternion.Inverse(FirstHeadRotation) * -FirstHeadPosition) and rotation Quaternion.Inverse(FirstHeadRotation) to TrackingSpace.4. Then set head and hand position normally(directly from OVRInput or InputSystem). In order to make height of head take effect, I set the Y axis of FirstHeadPosition to zero in step 3, so player could still put their head lower or higher. Also, if player long press menu button from controller to reset the view, I also can't get called from RecenteredPose callback from SDK, but fortunately, I found OVRPlugin.GetLocalTrackingSpaceRecenterCount() will plus 1 every time I reset the view form controller, so I can check this to decide to record the latest position and rotation as FIRST head position and rotation, and then set them to TrackingSpace to finish the reset view inside game. Hope those helps.

I don't want to manually trigger a recenter. I just want to subscribe to the event for when the playspace is recentered so my app can know when the user resets their view. Pls Oculus?

if you dont mind the users still using the oculus home to reset orientation. you can also include your own code to be called when it is pressed by using this.void Start(){ OVRManager.display.RecenteredPose += PlayerPressedOculusHome;}public void PlayerPressedOculusHome(){ Debug.Log("I Have Detected a headset Reset");}

I have the same issue running on Unity2018.3.12f1 I tried UnityEngine.XR.Recenter and also OVRManager.display.RecenterPose() neither of which work. I don't see any documentation on this but there should be because of VRC.Quest.Functional.9. Now if there is no way to do it on the quest because you have reserved that functionality for long pressing your home button than that needs to be said. But if this is a bug I have a minimal project that reproduces it.

Hey guys, you should look at this post: https://developer.oculus.com/first-access/santa-cruz/post/2265251466819472/

An Oculus rep "mfmf" has confirmed the behavior was intentionally disabled on Quest:
Followup: there will not be a way for apps to manually trigger a recenter. Users are expected to know how to recenter properly. We've made recenter much easier to trigger on Quest than Rift.

Hmm, thank you for this! It was definitely driving me crazy as to why it wasn't working on the Quest...

This is unfortunate, but at least there is an answer!

I don't understand. We should at least be able to know if the user has recentered the view by himself ?
@mfmf excuse me but as you have been cited and the post is no longer available could you (or someone from the staff) maybe comment or point toward some informations please ?

For info, this post has a super useful code snippet that will set player position and y-orientation on scene load:
Grrr. can't post links so try adding your own h.t.t.p.s. protocol to the following:

I found that you are at least *supposed* to be able to tell when the boundary changes or playspace is recentered in Unity using the XRInputSubsystem.boundaryChanged and XRInputSubsystem.trackingOriginUpdated delegates.

  I wish those events would work! But for me, none of the two fire when re-centering the view on the Quest 2. Neither in stationary nor roomscale boundary.

Being able to manually trigger a recenter would actually be SUPER helpful with HandTracking only, unless I'm missing how that works natively?

It seems like a poor design if in my game they have to pull up the Oculus menu, then go to setting, then recenter..

Exact
when recenter with hand tranckin in the game with gesture menu (RawButton.Start) for example????

My solution to HandTracking recenter with Gesture Menu (RawButton.Start)

public static void RecenterHeadset()
{
#if OCULUS_PLATFORM
if (OVRManager.display != null)
{
float currentRotY = CameraManager.Main.transform.eulerAngles.y; //This refence a CenterEyeAnchor
float difference = 0 - currentRotY;
InteractionSystem.AnchorPlayer.Rotate(0, difference, 0); // InteractionSystem.Anchor This refence a Player

Vector3 newPos = new Vector3(0 - CameraManager.Main.transform.position.x, 0, 0 - CameraManager.Main.transform.position.z);
InteractionSystem.AnchorPlayer.transform.position += newPos;
}
#endif
}

I hope it helps you ;)
