    Hi
    my project has been on hold for the last 5 months. Do i need to be aware of any upgrades to VR implementation for google cardboard, either from Unity or the SDK?
    thanks

    Highly unlikely. Pretty much nobody (including Google) does Cardboard anymore.

    @mgear thanks for the update. Does this fix the problem of toggling between 2d and VR mode? My app was crashing whenever i did this previously. Also does it include a replacement for GVRreticlepointer? So I can navigate in game in the editor?
    thanks for your efforts

    most of the help is coming from this topic
    https://github.com/googlevr/cardboard/issues/140

    for testing in editor,
    have to make own script apparently, i'm using this: (left alt down and move mouse to rotate cam)
    https://github.com/UnityCommunity/U...ssets/Scripts/Camera/EditorCardboardCamera.cs

    reticle:
    i'm actually still in 1.6, haven't checked if better reticle got added,
    for the timer i used UI 360 slider image with small script that sets the fill amount.. (raycast to detect if hover over target)
    and for the circular white expanding part, i used old reticle code (the one that builds circular mesh and expands it from shader)

    2d/vr mode switch:
    i had crashing also, their main example for switching mode doesnt work..
    i'm using some messy code like, and app is set to NOT have vr enabled at start (so its disabled from xr settings)

    thanks very much for that code - will give it a go... I have avoided upgrading to 2020 and am still on 2019.4.0f1... is that the best version to stick with?
    thanks

    i'm definitely staying with 2019.4.x on this one,
    and in general, avoiding 2020/2021, editor feels too sluggish..

    Hi I have implemented this code and it works the first time but the app crashes when i try to go back into VR. Any ideas? (I had to comment out the cam.* lines as they gave up errors in my editor)

    Code (CSharp):
    1. using System.Collections;
    2. using UnityEngine;
    3. using UnityEngine.XR.Management;
    4.  
    5.  
    6. public class VRToggle : MonoBehaviour
    7. {
    8.  
    9.     public bool vrOn;
    10.  
    11.     public void Start()
    12.     {
    13.         if (vrOn)
    14.         {
    15.            StartCoroutine(VRStart());
    16.  
    17.         }
    18.         else
    19.         {
    20.             VRStop();
    21.         }
    22.     }
    23.     public  IEnumerator VRStart()
    24.     {
    25.         var xrManager = XRGeneralSettings.Instance.Manager;
    26.         if (!xrManager.isInitializationComplete)
    27.         {
    28.             yield return xrManager.InitializeLoader();
    29.             xrManager.StartSubsystems();
    30.             Screen.sleepTimeout = SleepTimeout.NeverSleep;
    31.  
    32.         }
    33.        
    34.     }
    35.     public void VRStop()
    36.     {
    37.         var xrManager = XRGeneralSettings.Instance.Manager;
    38.         if (xrManager.isInitializationComplete)
    39.         {
    40.             xrManager.StopSubsystems();
    41.             xrManager.DeinitializeLoader();
    42.  
    43.             //cam.ResetAspect();
    44.             //cam.fieldOfView = defaultFov;
    45.             //cam.ResetProjectionMatrix();
    46.             //cam.ResetWorldToCameraMatrix();
    47.             Screen.sleepTimeout = SleepTimeout.SystemSetting;
    48.         }
    49.  
    50.     }
    51. }

    my app has xr disabled at start:
    upload_2021-10-7_13-42-53.png

    StartXR, not sure if much difference to yours:
    Code (CSharp):
    1. private IEnumerator StartXR()
    2. {
    3.     Debug.Log("Initializing XR...");
    4.     if (!XRGeneralSettings.Instance.Manager.isInitializationComplete) yield return XRGeneralSettings.Instance.Manager.InitializeLoader();
    5.     yield return 0;
    6.  
    7.     if (XRGeneralSettings.Instance.Manager.activeLoader == null)
    8.     {
    9.         Debug.LogError("Initializing XR Failed.");
    10.     }
    11.     else
    12.     {
    13.         Debug.Log("Starting XR...");
    14.         XRGeneralSettings.Instance.Manager.StartSubsystems();
    15.     }
    16.  
    stopXR
    Code (CSharp):
    1. Debug.Log("Stopping XR...");
    2. if (XRGeneralSettings.Instance != null) XRGeneralSettings.Instance.Manager.StopSubsystems();
    3. Camera.main.ResetAspect();

    yes - that is unchecked at the start since user begins in 2d screens
    I swapped my code for your and now see this error when I try going back into VR
    Initializing XR Failed.
    UnityEngine.Debug:LogError(Object)
    <VRStart>d__2:MoveNext() (at Assets/MyStuff/Scripts/VRToggle.cs:33)
    UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)

    Code (CSharp):
    1.  if (XRGeneralSettings.Instance.Manager.activeLoader == null)
    2.         {
    3.             Debug.LogError("Initializing XR Failed.");
    4.         }

    (not sure if relevant but I haven't installed the latest SDK you linked to, primarily because I can't see a unitypackage file when i download). Do I need that installed? If so how do I do this without the package manager? thanks )

    ok did it that way but still get the same error - presumably this is why it is crashing... any ideas? NB I now can't enter VR mode when i install the app on phone (android). This is both with your code and mine
    any other ideas? thanks

    Hi, it looks like you are using 1.6.0. There are some bug fixes, and improvements in the new 1.8.0 plugin.

    Hi, try this on line 27-28:
    Code (CSharp):
    1.   Debug.Log("Initializing XR...");
    2.             yield return XRGeneralSettings.Instance.Manager.InitializeLoader();
    And check "Cardboard XR Plugin, and uncheck "Initialize XR on Startup" in Project Settings/XR-Plug-in Management.

    thanks - so it looks like this:
    Code (CSharp):
    1. Debug.Log("Initializing XR...");
    2.         /*if (!XRGeneralSettings.Instance.Manager.isInitializationComplete)*/ yield return XRGeneralSettings.Instance.Manager.InitializeLoader();
    3.         yield return 0;
    (box unchecked on startup)

    I am also tring to use this code from the documentation
    Code (CSharp):
    1. Coroutine VRStart()
    2.     {
    3.         return StartCoroutine(startVRRoutine());
    4.         IEnumerator startVRRoutine()
    5.         {
    6.             // Add error handlers for both Instance and Manager
    7.             var xrManager = XRGeneralSettings.Instance.Manager;
    8.             if (!xrManager.isInitializationComplete)
    9.                 yield return xrManager.InitializeLoader();
    10.             if (xrManager.activeLoader != null)
    11.                 xrManager.StartSubsystems();
    12.             // Add else with error handling
    13.         }
    14.     }
    but how do i get the code to run? I thought you called ienumerators not coroutines?

    thanks

    I also tried the code that mgear posted adding in a bool to determine which function to run:
    Code (CSharp):
    1. using System.Collections;
    2.  
    3. using UnityEngine;
    4. using UnityEngine.XR.Management;
    5.  
    6.  
    7. public class startXR : MonoBehaviour
    8. {
    9.     public bool xrStart;
    10.     public void Start()
    11.     {
    12.         if (xrStart)
    13.         {
    14.             StartCoroutine(StartXR());
    15.         }
    16.         else
    17.         {
    18.             StopXR();
    19.         }
    20.     }
    21.  
    22.     public IEnumerator StartXR()
    23.     {
    24.         Debug.Log("Initializing XR...");
    25.         yield return XRGeneralSettings.Instance.Manager.InitializeLoader();
    26.  
    27.         if (XRGeneralSettings.Instance.Manager.activeLoader == null)
    28.         {
    29.             Debug.LogError("Initializing XR Failed. Check Editor or Player log for details.");
    30.         }
    31.         else
    32.         {
    33.             Debug.Log("Starting XR...");
    34.             XRGeneralSettings.Instance.Manager.StartSubsystems();
    35.         }
    36.     }
    37.  
    38.     void StopXR()
    39.     {
    40.         Debug.Log("Stopping XR...");
    41.  
    42.         XRGeneralSettings.Instance.Manager.StopSubsystems();
    43.         XRGeneralSettings.Instance.Manager.DeinitializeLoader();
    44.         Debug.Log("XR stopped completely.");
    45.     }
    46. }
    47.  
    I think this is the full error log entry:
    using System.Collections;

    using UnityEngine;
    using UnityEngine.XR.Management;


    public class startXR : MonoBehaviour
    {
    public bool xrStart;
    public void Start()
    {
    if (xrStart)
    {
    StartCoroutine(StartXR());
    }
    else
    {
    StopXR();
    }
    }

    public IEnumerator StartXR()
    {
    Debug.Log("Initializing XR...");
    yield return XRGeneralSettings.Instance.Manager.InitializeLoader();

    if (XRGeneralSettings.Instance.Manager.activeLoader == null)
    {
    Debug.LogError("Initializing XR Failed. Check Editor or Player log for details.");
    }
    else
    {
    Debug.Log("Starting XR...");
    XRGeneralSettings.Instance.Manager.StartSubsystems();
    }
    }

    void StopXR()
    {
    Debug.Log("Stopping XR...");

    XRGeneralSettings.Instance.Manager.StopSubsystems();
    XRGeneralSettings.Instance.Manager.DeinitializeLoader();
    Debug.Log("XR stopped completely.");
    }
    }

    Perhaps easiest then to start over with a brand new project, and make it run with the demo scene?
    When the basics is up and running, then disable the "Initialize VR on Startup" and put back this custom code.

    so i followed these instructions: https://developers.google.com/cardboard/develop/unity/quickstart
    built the app but when i launch it, it launches in 2d not VR - is that right? The documentation seems to suggest it should launch in 3d

    So i added the script:
    Code (CSharp):
    1. using System.Collections;
    2.  
    3. using UnityEngine;
    4. using UnityEngine.XR.Management;
    5.  
    6.  
    7. public class startXR : MonoBehaviour
    8. {
    9.     public bool xrStart;
    10.     public void Start()
    11.     {
    12.         if (xrStart)
    13.         {
    14.             StartCoroutine(StartXR());

    No..., the demo should launch in VR. Check the "Initialize XR on Startup" for that. You should probably look at the NullReferenceException, also. Dont think it belongs to the demo scene. Just follow the steps.

    Based on earlier posts I understood this had to be unchecked on launch.
    i have checked it and still get this error:
    Please initialize Cardboard XR loader before calling this function

    Can you help me fix that?
    thanks

    Please can someone help on this? I have been bouncing around forums and threads on this all weekend but have been unable to find a solution. I have tried on a new clean app and in my existing set up but just get the same errors: Please initialize Cardboard XR loader before calling this function.

    Coping the code from the Unity Documentation:
    Code (CSharp):
    1. using System.Collections;
    2. using UnityEngine;
    3.  
    4. using UnityEngine.XR.Management;
    5.  
    6. public class ManualXRControl
    7. {
    8.     public IEnumerator StartXR()
    9.     {
    10.         Debug.Log("Initializing XR...");
    11.         yield return XRGeneralSettings.Instance.Manager.InitializeLoader();
    12.  
    13.         if (XRGeneralSettings.Instance.Manager.activeLoader == null)
    14.         {
    15.             Debug.LogError("Initializing XR Failed. Check Editor or Player log for details.");
    16.         }
    17.         else
    18.         {
    19.             Debug.Log("Starting XR...");
    20.             XRGeneralSettings.Instance.Manager.StartSubsystems();
    21.         }
    22.     }
    23.  
    24.     void StopXR()
    25.     {
    26.         Debug.Log("Stopping XR...");
    27.  
    28.         XRGeneralSettings.Instance.Manager.StopSubsystems();
    29.         XRGeneralSettings.Instance.Manager.DeinitializeLoader();
    30.         Debug.Log("XR stopped completely.");
    31.     }
    32. }
    33.  
    34.  
    Fails here:
    Code (CSharp):
    1.      if (XRGeneralSettings.Instance.Manager.activeLoader == null)
    2.         {
    3.             Debug.LogError("Initializing XR Failed. Check Editor or Player log for details.");
    4.         }
    I have created a new 3D project and followed each line of the instructions. I am running 2019.4.31fi

    In Editor
    I have tried running the sample HelloWorldVR scene and get these errors. It doesn't matter if i check the Initialise XR on start up box:
    Please initialize Cardboard XR loader before calling this function.
    UnityEngine.Debug:LogError (object)
    Google.XR.Cardboard.Api:UpdateScreenParams () (at Library/PackageCache/com.google.xr.cardboard@d9f0aa2eb0/Runtime/Api.cs:295)
    CardboardStartup:Update () (at Assets/Samples/Google Cardboard XR Plugin for Unity/1.8.0/Hello Cardboard/Scripts/CardboardStartup.cs:70)

    If I comment out this line it stops the errors
    Api.UpdateScreenParams();

    In app
    If I comment out this line it stops the errors
    Api.UpdateScreenParams();
    If I leave the Initialise XR on startup un checked then it doesn't launch in split screen
    If I check the box then it launches in split screen but the view doesn't change as I move my head

    If I don't comment out
    Api.UpdateScreenParams();
    HelloWorldVR works

    So I tried copying over CardboardStartup into a new VR scene
    If I turn off the toggle for Initialise XR on start up box start with a 2D screen then switch to VR, it remains in 2D it doesn't go split screen
    If I leave that toggle on and only launch my VR scene it still stays in 2D
    So I tried adding the toggle script and that made no difference.


    Is there no definitive answer on this? It seems a fair few people have hit the same problem. According to this post it was fixed about a year ago so should be part of the 1.8.0 plugin?
    https://github.com/googlevr/cardboard/issues/98


    This is doing my head and any help in resolving once and for all would be much appreciated
    thanks

    How about breaking up the StartXR into a method, thats starts Coroutine? Like this:

    Code (CSharp):
    1. bool vron;
    2. public void StartXR() {
    3.    StartCouroutine(StartXRRoutine());
    4. )
    5.  
    6. public IEnumerator StartXRRoutine()
    7.     {
    8.         if (vron)
    9.             yield break;
    10.  
    11.         vron = true;
    12.         Debug.Log("Initializing XR...");
    13.         yield return XRGeneralSettings.Instance.Manager.InitializeLoader();
    14.         if (XRGeneralSettings.Instance.Manager.activeLoader == null)
    15.         {
    16.             Debug.LogError("Initializing XR Failed. Check Editor or Player log for details.");
    17.             vron = false;
    18.         }
    19.         else
    20.         {
    21.             Debug.Log("Starting XR...");
    22.             XRGeneralSettings.Instance.Manager.StartSubsystems();
    23.         }
    24.     }

    And add vron = false; to the StopXR() method.

    i tested the sample scenes from 1.8 in empty project, switch between 2d/3d worked,
    i think it had the error message "initialize first before calling", but no crash.

    then used my vrmanager code above, to switch and fix aspect ratio, no crash, no error messages, and did disable initial VR mode, so it starts in 2D.

    I wish I could do that! I have tested on Motorola Moto G(7) and do not get this result. When you say you can switch between VR and 2d in the test project, do you mean you set up new 2d scene and added in your code? "i tested the sample scenes from 1.8 in empty project, switch between 2d/3d worked," I only see two scenes in sample project HelloCardboard VR and VrMode which I believe are both in 3D?

    I have added 2d scenes to switch between but perhaps this was unnecessary?

    VrMode scene: yeah i meant "2D" as in no-vr.

    I'll upload the project to github later, so can test.

    thanks but when I download the zip file it is empty - when I look in the folders unders "assets" I don't see Test VRMode.scene when i traverse the directory structure on github, or any scripts
    any ideas?

    Got it :) i have built and loaded the scene in 2D. When I choose the switch to VR button nothing happens. I assume it should go to split screen?

    This is an extract from the log when i try to select each button

    did you click with gaze on the button, it should turn red, then click screen with finger?

    can ignore those "Calling function OnPointerExit with no parameters but the function requires 1." (the script is attached to button so it complaints about that)

    doh - i only use gaze and pick so never occurred to me. So now this is what I get:
    A non split screen on loading - it is still controlled by moving the phone around to see the scene (not by dragging finger)
    I highlight the Enable VR button and tap on it and the screen splits
    I highlight the Disable VR button and tap on it and the screen goes back to full screen
    I can repeat this without the app crashing

    So I copied the script and the scene to my live project.
    I built with just this one scene
    I installed on my phone
    When I open the app, the full screen appears. But I can't move the screen, by rotating the phone and I can't tap the button to go into VR mode
    If I tap the enableVR button the app then crashes

    I built in debug mode but for some reason i can see the phone in the console but when I choose it it reverts to editor option

    So my assumption is that there is a problem with my environment but I have no idea where to look!

    thanks
