SetUp Firebase:
1. Enter in Firebase: https://firebase.google.com/
2. Create a Project.
3. Add a Unity app and follow the steps below.
4. Make sure to initialize the services you want to use and after that, re-download the google-service.json from the project configuration / your apps / sdk configuration.
5. Now install the services you are going to use from the firebase_unity_sdk you downloaded creating the app, do not forget that this project uses FirebaseDatabase, FirebaseAuth and FirebaseStorage, although you can always comment the code that gives you an error if you do not want to use any of the services, although it is recommended not to do it with FirebaseAuth for the security of your data.
SetUp VRTemplate:
1. Import Animation rigging.
2. Import TextMeshpro Essentials.
3. Import VRTemplate.
4. Build scenes.
5. Go to VRTemplate/Prefabs/Player/VR_Player inside the prefab in Settings/VRSettingsPlayer add an Action to be able to open the menu.
6. Repeat the process in file Assets/Photon/PhotonVoice/Resources/VoiceAppsettings as in the step 11 of SetUp Photon.
7. It is time to test that everything goes well, for this it is important that you understand that the extension must always start from Offline so we will always start with LobbyScene for the tests. Open LobbyScene and press play.
Unity versions tested:
2021.3.21f1
2021.3.16f1
2020.3.46f1
Change Build version:
There are two ways to build in this template, one for VR devices and one for Window, Android and Ios (Not VR). In order to make the build in one way or another, 2 things must be taken into account.
In the LobbyScene the VRPlayer prefab must be changed to the NotVRPlayer prefab in order to make one version or the other.
ProjectSettings/XR Plugin Management must be enabled or disabled.
Build VR = VRPlayer on the first scene and XRPluginManagement enabled.
Build Not VR = NotVRPlayer on the first scene and XRPluginManagement disabled.
All this is independent of what type of build you have selected in build settings.
