Building a stand alone exe with Google Cardboard

I have a Unity project that contains the Google VR SDK.
When I press play, everything works as it should, as well as the Oculus Rift head set displaying the correct images.

When I try to build and run, I get a series of errors. Mostly NullReferenceExceptions.

Is it even possible to build an exe for Windows with the Google Cardboard SDK?

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object
2.   at Cardboard.OnApplicationFocus (Boolean focus) [0x00000] in <filename unknown>:0
3.  
4. (Filename:  Line: -1)
5.  
6. NullReferenceException: Object reference not set to an instance of an object
7.   at Cardboard.Projection (Eye eye, Distortion distortion) [0x00000] in <filename unknown>:0
8.   at CardboardEye.UpdateStereoValues () [0x00000] in <filename unknown>:0
9.   at CardboardEye.Start () [0x00000] in <filename unknown>:0
10.  
11. (Filename:  Line: -1)
12.  
13. NullReferenceException: Object reference not set to an instance of an object
14.   at Cardboard.Recenter () [0x00000] in <filename unknown>:0
15.   at Menu.recalb () [0x00000] in <filename unknown>:0
16.   at Menu.Start () [0x00000] in <filename unknown>:0

 

You have to hack a bit the source code to enable the editor emulation in the final build. I did it for a project.

 

Any hints where to find a guide for this? I've tried googling but can't find much.

 

Open the sources and replace some #if UNITY_EDITOR by #if UNITY_EDITOR || UNITY_STANDALONE

BaseVRDevice.cs

Code (CSharp):

1. #if UNITY_EDITOR || UNITY_STANDALONE
2. device = new EditorDevice();
3. #elif ANDROID_DEVICE
4. // Rest of the code
5. #endif

EditorDevice.cs

Code (CSharp):

1.  
2. #if UNITY_EDITOR || UNITY_STANDALONE
3. using UnityEngine;
4.  
5. private bool RemoteCommunicating {
6.     get {
7.         if (!remoteCommunicating) {
8.             remoteCommunicating = EditorApplication.isRemoteConnected;
9.             // You have to comment that line
10.             //remoteCommunicating = EditorApplication.isRemoteConnected;
11.         }
12.         return remoteCommunicating;
13. }
14. // Rest of the code
15. #endif
16.  

GvrViewer.cs

Code (CSharp):

1.  
2. #if UNITY_EDITOR || UNITY_STANDALONE
3. /// Restores level head tilt in when playing in the Unity Editor after you
4. /// release the Ctrl key.
5. public bool autoUntiltHead = true;
6. // The rest of the code
7. #endif
8.  

 

demonixis thank you! Excelent hacking. That work around worked for me.

 

When I replace these 3 #if UNITY_EDITOR by #if UNITY_EDITOR || UNITY_STANDALONE, if i try to build i have an error.

Assets/GoogleVR/Legacy/Scripts/Internal/VRDevices/EditorDevice.cs(17,7): error CS0246: The type or namespace name `UnityEditor' could not be found. Are you missing an assembly reference?

Hi, I managed to fix it by using the following

Code (CSharp):

1. #if UNITY_EDITOR|| UNITY_STANDALONE
2.  
3. using UnityEngine;
4. #if UNITY_EDITOR
5. using UnityEditor;
6. #endif
7. using System.Collections.Generic;

Code (CSharp):

1. private bool RemoteCommunicating {
2.       get {
3. #if UNITY_EDITOR
4.         if (!remoteCommunicating) {
5.           remoteCommunicating = EditorApplication.isRemoteConnected;
6.         }
7.         return remoteCommunicating;
8. #endif
9. #if UNITY_STANDALONE
10.         return false;
11. #endif
12.         }
13.     }

 

Hi,
Is there any way to achieve this for the latest googlevr sdk ? As after adding the latest googlevr sdk and making PC build it says add a platform Daydream or Cardboard... but there is no such option in PC build under virtual reality supported player setting...Any help ? The old hacks told above worked great before.
