The Cloud Functions for Firebase Unity Sample demonstrates the Firebase SDK for Cloud Functions with the Firebase Unity SDK inside the Unity Editor.

• Unity 5.3 or higher.
• Xcode 9.4.1 or higher (when developing for iOS).
• Android SDK (when developing for Android).

• Install the Firebase CLI.
• Deploy the provided functions.

  # Move to the `Assets/Firebase/Sample/Functions/.functions` subdirectory of
  # the sample.
  cd Assets/Firebase/Sample/Functions/.functions
  
  # Install all of the dependencies of the cloud functions
  cd functions
  npm install
  cd ..
  
  # Initialize the directory as your project directory.
  # * Do not select a default project.
  # * Select JavaScript as functions language.
  # * Do not overwrite packages.json and index.js files.
  firebase init functions
  # Deploy functions to your Firebase project
  firebase --project=YOUR_PROJECT_ID deploy --only functions

• Download the Firebase Unity SDK and unzip it somewhere convenient.
• Open the sample project in the Unity editor.
  • Select the File > Open Project menu item.
  • Click Open.
  • Navigate to the sample directory testapp in the file dialog and click Open.
• Open the scene MainScene.
  • Navigate to Assets/Firebase/Sample/Functions in the Project window.
  • Double click on MainScene file to open.
• Import the Firebase Auth plugin.
  • Select the Assets > Import Package > Custom Package menu item.
  • From the Firebase Unity SDK downloaded previously, import FirebaseAuth.unitypackage from the directory that matches the version of Unity you use:
    • Unity 5.x and earlier use the .NET 3.x framework, so you need to import the dotnet3/FirebaseAuth.unitypackage package .
    • Unity 2017.x and newer allow the use of the .NET 4.x framework. If your project is configured to use .NET 4.x, import the dotnet4/FirebaseAuth.unitypackage package.
  • When the Import Unity Package window appears, click the Import button.
• Import the Firebase Functions plugin.
  • Select the Assets > Import Package > Custom Package menu item.
  • From the Firebase Unity SDK downloaded previously, import FirebaseFunctions.unitypackage from the directory that matches the version of Unity you use:
    • Unity 5.x and earlier use the .NET 3.x framework, so you need to import the dotnet3/FirebaseFunctions.unitypackage package .
    • Unity 2017.x and newer allow the use of the .NET 4.x framework. If your project is configured to use .NET 4.x, import the dotnet4/FirebaseFunctions.unitypackage package.
  • When the Import Unity Package window appears, click the Import button.

Once you have done this, you can run the Unity Editor and test the application.

• Register your iOS app with Firebase.

  • Create a project in the Firebase console, and associate your iOS application.
    • You should use com.google.firebase.unity.functions.testapp as the package name while you're testing.
      • If you do not use the prescribed package name you will need to update the bundle identifier as described in the Optional: Update the Project Bundle Identifier below.

• Add the GoogleService-Info.plist file to the project.

  • Navigate to the Assets/Firebase/Sample/Functions folder in the Project window.
  • Drag the GoogleService-Info.plist downloaded from the Firebase console into the folder.
    • NOTE: GoogleService-Info.plist can be placed anywhere under the Assets folder.

• Optional: Update the Project Bundle Identifier

  • If you did not use com.google.firebase.unity.functions.testapp as the project package name you will need to update the sample's Bundle Identifier.
    • Select the File > Build Settings menu option.
    • Select iOS in the Platform list.
    • Click Player Settings
    • In the Player Settings panel scroll down to Bundle Identifier and update the value to the package name you provided when you registered your app with Firebase.

• Build for iOS

  • Select the File > Build Settings menu option.
  • Select iOS in the Platform list.
  • Click Switch Platform to select iOS as the target platform.
  • Wait for the spinner (compiling) icon to stop in the bottom right corner of the Unity status bar.
  • Click Build and Run.

• Register your Android app with Firebase.
  • Create a project in the Firebase console, and attach your Android app to it.

    • You should use com.google.firebase.unity.functions.testapp as the package name while you're testing.

      • If you do not use the prescribed package name you will need to update the bundle identifier as described in the Optional: Update the Project Bundle Identifier below.

    • To generate a SHA1, first you will need to set the keystore in the Unity project.

      • Locate the Publishing Settings under Player Settings.
      • Select an existing keystore, or create a new keystore using the toggle.
      • Select an existing key, or create a new key using "Create a new key".

    • After setting the keystore and key, you can generate a SHA1 by running this command:

      keytool -exportcert -list -v -alias <key_name> -keystore <path_to_keystore>
      

  • Download the google-services.json file associated with your Firebase project from the console. This file identifies your Android app to the Firebase backend, and will need to be included in the sample later.
    • For further details please refer to the general instructions which describes how to configure a Firebase application for Android.
• Add the google-services.json file to the project.
  • Navigate to the Assets/Firebase/Sample/Functions folder in the Project window.
  • Drag the google-services.json downloaded from the Firebase console into the folder.
    • NOTE: google-services.json can be placed anywhere under the Assets folder.
• Optional: Update the Project Bundle Identifier
  • If you did not use com.google.firebase.unity.functions.testapp as the project package name you will need to update the sample's Bundle Identifier.
    • Select the File > Build Settings menu option.
    • Select Android in the Platform list.
    • Click Player Settings
    • In the Player Settings panel scroll down to Bundle Identifier and update the value to the package name you provided when you registered your app with Firebase.
