Question XR Plugin Management Initialize on Startup

Hello, I'm using the new XR system, on my UWP game I have disable the option Initialize on Startup but in the final UWP master build the VR start Always when the game started, I don't know why.
In the Unity editor works properly and VR doesn't start on game start, thank you, Best regards…

Universal Windows Platform
Visual Studio 2017 community Version 4.8.03752
Unity 2019.3.0f6
new XR system

 

Yes, with the boot.config modification the VR doesn't start when the game start, but the code to enable XR at Runtime doesn't works, in the Unity editor the same code to enable/disable XR works properly, thank you, Cheers...

Code (CSharp):

1.     private void EnableVisor()
2.     {
3.       UnityEngine.XR.Management.XRGeneralSettings.Instance.Manager.InitializeLoaderSync();
4.  
5.       UnityEngine.XR.Management.XRGeneralSettings.Instance.Manager.StartSubsystems();
6.     }
7.     private void DisableVisor()
8.     {
9.       UnityEngine.XR.Management.XRGeneralSettings.Instance.Manager.StopSubsystems();
10.  
11.       UnityEngine.XR.Management.XRGeneralSettings.Instance.Manager.DeinitializeLoader();
12.     }

Use coroutines to init XR:

Code (CSharp):

1.  public IEnumerator InitXR()
2.     {
3.         yield return  XRGeneralSettings.Instance.Manager.InitializeLoader();
4.     }

Simple "XRGeneralSettings.Instance.Manager.InitializeLoader();" did not work.

 

Can anybody tell, why camera image freeze after return to 2d mode by "XRGeneralSettings.Instance.Manager.StopSubsystems();" ?

 

Hi, thank you very much for your suggestion, at this time I'm using a deprecated WMR package but soon I will update my project to use the new XR system, Cheers...

 

Also @joejo those docs have been obviously wrong in this topic for months (still are). I've asked 2 or 3 times of Unity staff on these forums what the correct docs should be, and I've so far been ignored every time, which is disappointing.

1. It says "to add/create, remove, reorder ... use these methods" ... none of those methods add, none of them create, and none of them re-order .
2. About 2 screens later on that page, you get to a section that DOES describe how to re-order, but according to the API docs it's using a setter (.loaders) that doesn't exist. It seems the API docs are wrong, since we can assign to that variable?

...but it also seems to overwrite the data in the project, instead of only at runtime, which leaves me thinking "surely this isn't the way they intend us to control which headsets are being loaded? Runtime methods that change the project assets are a nightmare and this can't be right?"

 

Hello everyone, I just started putting the CardBoard plugin in it.
I don't need to have it running as the app runs so what I do is the code posted above:

Code (CSharp):

1.  public IEnumerator InitXR()
2.     {
3.         yield return  XRGeneralSettings.Instance.Manager.InitializeLoader();
4.     }

And I call that function in the

Start()

function of my main GameObject, and then, after at least 20s I actually run

 UnityEngine.XR.Management.XRGeneralSettings.Instance.Manager.StartSubsystems();

, but as I run

StartSubsystems()

the apps crashes with no useful extra information.

Am I doing something wrong?

 

In the last week, I've @-mentioned two of the Unity team who've talked about this specifically, and had replies from neither . Plus the multiple times I've replied to them on the forums (going back ... a month? more?) requesting clear up-to-date docs on this specific topic.

At this point you're best filing a new bug, waiting 4-6 weeks, and then you can discuss it with them when they read it (based on current wait times, that's about how long it takes for XR bugs to get looked at). Hopefully you'll get a reply before you need it for your live project.

 

Same problem here, the problem is with the DeinitializeLoader() function

 

Same issue here with the DeInitializeLoader() function. The code below works when I call the function StartXR() and the function StopXR() but if I call again the StartXR() function, the app crash. I think the problem is the DeinitializeLoader() funtion.

Code (CSharp):

1.  
2. IEnumerator StartXR()
3. {
4.     yield return XRGeneralSettings.Instance.Manager.InitializeLoader();
5.     if (XRGeneralSettings.Instance.Manager.activeLoader == null)
6.     {
7.         Debug.LogError("Initializing XR Failed. Check Editor or Player log for details.");
8.     }
9.     else
10.     {
11.         Debug.Log("Starting XR...");
12.         XRGeneralSettings.Instance.Manager.StartSubsystems();
13.         yield return null;
14.     }
15. }
16.  
17. void StopXR()
18. {
19.     if (XRGeneralSettings.Instance.Manager.isInitializationComplete)
20.     {
21.         XRGeneralSettings.Instance.Manager.StopSubsystems();
22.         Camera.main.ResetAspect();
23.         XRGeneralSettings.Instance.Manager.DeinitializeLoader();
24.     }
25. }

Any help?

 

Hi joejo,

First of all, what do you mean by "provider"?

Secondly, I used the Windows terminal command "adb logcat -s Unity" to debug the app but I cannot find error or exception.
In the first one (Start1) the debug terminal show the code below:

08-07 13:56:04.266  9073  9121 D Unity   : [Subsystems] Loading plugin CardboardXrProvider for subsystem Display...

08-07 13:56:04.270  9073  9121 D Unity   : [Subsystems] Cardboard successfully registered Provider for Display

08-07 13:56:04.272  9073  9121 I Unity   : [XR] [CardboardXrInputProvider]: Lifecycle initialized

The second time I call the Initialization function (Start1 --> Stop1 -->Start2), the application flow ends with "[Subsystems] Loading plugin CardboardXrProvider for subsystem Display..." :

08-07 13:56:10.440  9073  9121 D Unity   : [Subsystems] Loading plugin CardboardXrProvider for subsystem Display...

08-07 13:56:19.775  9073  9073 I Unity   : onDestroy

Have you any idea to find a solution?

 

Google's Cardboard sdk too.. I'll check their forums

 

I use this code. I use StartXR on the start of my player once he switches to a certain scene.
But somehow eh doesn't do the 'yield return XRGeneralSettings.Instance.Manager.InitializeLoader();' correctly and i get the error " Debug.LogError("Initializing XR Failed. Check Editor or Player log for details.");"

What can I do to fix this? I use this in another project and there it works fine.

 

Ofcourse but there was nothing there.
Seemed it was the steamvr that needed an update

 

tnks , its work

 

It works smoothly to me with Oculus Quest2. Thanks Jabba!
