I added more options to PhotonVRManager I might change some scripts later but this is what I got.

Disclaimer

Fchb1239 please check my code if it works. I'm not perfect at coding.

There might be some bugs in the code. Please have mercy with me.

I tested it in my game and it worked.

I only edited PhotonVRManager so just copy and paste this into your PhotonVRManager.

Stuff I added

I added a dev region choice. Meaning if your apk is a development build, it's going to connect to the dev region.

        [Tooltip("The region that people connect to if the apk is a development build (check your build settings).")]
        public string DevRegion = "";

I also added a Offline mode bool. Meaning that it simulates an online connection. PUN can be used as if it was in an online connection.

        [Tooltip("Simulates an online connection.\nPUN can be used as usual.")]
        public bool StartInOfflineMode = false;

I also also added more connection states for more debugging.

    public enum ConnectionState
    {
        Disconnected,
        Connecting,
        Connected,
        JoiningRoom,
        InRoom,
        Error,
        Generating_Roomcode,
        Switching_Scenes,
        Setting_Up_Settings
    }

I just basically made it more easy so you don't have to go manually into the Photon server settings and just be able to control Photon from one script.

I am adding some stuff to PhotonVRManager.

[TMTimeVR]

I also also ALSO added a TMP that you can assign and it will say what's going on.

        [Tooltip("Basically a tmp that says what PhotonVRManager is doing.")]
        public static TextMeshPro LogText;

            if (Manager == null)
            {
                Manager = this;
                Manager.State = ConnectionState.Setting_Up_Settings;
                LogText.text = "Setting Up Settings..."; //Here
                PhotonNetwork.PhotonServerSettings.DevRegion = DevRegion;
            }
            else if (StartInOfflineMode == true)
            {
                PhotonNetwork.PhotonServerSettings.StartInOfflineMode = true;
            }
            else if (StartInOfflineMode == false)
            {
                PhotonNetwork.PhotonServerSettings.StartInOfflineMode = false;
            }
            else
            {
                Debug.LogError("There can't be multiple PhotonVRManagers in a scene");
                Manager.State = ConnectionState.Error;
                LogText.text = "ERROR: There can't be multiple PhotonVRManagers in a scene."; //Also here
                Application.Quit();
            }

this entire function should never have been changed

[TMTimeVR]

I think that was bc I changed photon vr version 0.0.5 or 0.0.4

[CoolPuppyKid]

the cases under the error case are just not needed

[TMTimeVR]

This pull request is pretty old. I will create a new one in a few days (or hours) where I fix the bugs in my code.
