Google Play Games plugin for Unity

The Google Play Games plugin for Unity® is an open-source project whose goal is to provide a plugin that allows game developers to integrate with the Google Play Games API from a game written in Unity®. However, this project is not in any way endorsed or supervised by Unity Technologies.

Unity® is a trademark of Unity Technologies.

iOS is a trademark of Apple, Inc.

Overview

The Google Play Games plugin for Unity allows you to access the Google Play Games API through Unity's social interface. The plugin provides support for the following features of the Google Play Games API:

sign in
friends
unlock/reveal/increment achievement
post score to leaderboard
cloud save read/write
show built-in achievement/leaderboards UI
events
nearby connections

NOTICE: This version of the plugin no longer supports iOS. Google Play games services for iOS is deprecated, and is not likely to function as expected. Do not use Google Play games services for iOS in new apps. See the deprecation announcement blog post for more details.

Features:

easy GUI-oriented project setup (integrated into the Unity GUI)
no need to override/customize the player Activity
no need to override/customize AndroidManifest.xml

System requirements:

Unity® 2017.4 or above.
To deploy on Android:
- Android SDK
- Android v4.0 or higher
- Google Play Services library, version 11.6 or above

Upgrading

If you have already integrated your project with a previous version of the plugin and wish to upgrade to a new version, please refer to the upgrade instructions.

Configure Your Game

To use the plugin, you must first configure your game in the Google Play Developer Console. Follow the instructions on creating a client ID. Be particularly careful when entering your package name and your certificate fingerprints, since mistakes on those screens can be difficult to recover from.

Copy the game resources from the console

Once you configure at least one resource (event, achievement, or leaderboard), copy the resource configuration from the Google Play Developer Console, and paste it into the setup configuration in Unity. To get the resources go to the Achievements tab, then click on "Get resources" on the bottom of the list.

Then click the "Android section".

Select all the contents of the resources window, and copy them to the clipboard.

Paste the game resources into the plugin setup dialog

Back in Unity, open the setup dialog Window > Google Play Games > Setup... > Android Setup

Enter the directory to save constants - Enter the folder for the constants file.
Constants class name - this is the name of the C# class to create, including namespace.
Resources Definition - paste the resource data from the Play Games console here.
Web client ID - this is the client ID of the linked web app. It is only needed if you have a web-based backend for your game and need a server auth code to be exchanged for an access token by the backend server, or if you need an id token for the player to make other, non-game, API calls.

The setup process will configure your game with the client id and generate a C# class that contains constants for each of your resources.

Setup Checklist

Make sure to do the following if they are relevant to your game:

Add tester email addresses to the testing section of your game on the Play Games Console.
The SHA1 fingerprint used to create the linked Android app is from the keystore used to sign the Unity application.

Add Achievements and Leaderboards

Add achievements and leaderboards to your game in the Google Play Developer Console. For each achievement and leaderboard you configure, make sure to note the corresponding achievement ID or leaderboard ID, as those will be needed when making the API calls. Achievement and leaderboard IDs are alphanumeric strings (e.g. "Cgkx9eiuwi8_AQ").

Add Events

Events allow you to track user actions in your game and report on them with Analytics. Read more about how to configure and use Events on Game Concepts - Events

Load Your Game Project

Next, load your game project into the Unity editor.

If you do not have a game project to work with, you can use the Minimal sample available in the samples directory. Using that sample will allow you to quickly test your setup and make sure you can access the API.

If you want to test a larger sample after you are familiar with the plugin, try the CubicPilot game. More information about building the samples can be found in the samples README file.

Plugin Installation

To download the plugin, clone this Git repository into your file system (or download it as a ZIP file and unpack it). Then, look for the unitypackage file in the current-build directory:

current-build/GooglePlayGamesPluginForUnity-X.YY.ZZ.unitypackage

To install the plugin, simply open your game project in Unity and import that file into your project's assets, as you would any other Unity package. This is accomplished through the Assets > Import Package > Custom Package menu item (you can also reach this menu it by right-clicking the Assets folder).

Next, make sure your current build platform is set to Android. From File > Build Settings… select Android and click Switch Platform. You should now see a new menu item was added under Window > Google Play Games. If you don't see the new menu items, refresh the assets by clicking Assets > Refresh and try again.

Android Setup

Next, set up the path to your Android SDK installation in Unity. This is located in the preferences menu, under the External Tools section.

To configure your Unity game to run with Google Play Games on Android, first open the Android SDK manager and verify that you have downloaded the following packages. Depending on if you are using the SDK manager from Android Studio, or using the standalone SDK manager, the name of the components may be different.

Google Play Services
Android Support Library
Local Maven repository for Support Libraries (Also known as Android Support Repository)
Google Repository
Android 6.0 (API 23) (this does not affect the min SDK version).

Next, configure your game's package name. To do this, click File > Build Settings, select the Android platform and click Player Settings to show Unity's Player Settings window. In that window, look for the Bundle Identifier setting under Other Settings. Enter your package name there (for example com.example.my.awesome.game).

In order to sign in to Play Game Services, you need to sign your APK file, make sure that you are signing it with the correct certificate, that is, the one that corresponds to the SHA1 certificate fingerprint you entered in the Developer Console during the setup.

Next, click the Window |Google Play Games|Setup - Android setup menu item. This will display the Android setup screen.

Enter the Constants class name. This is the name of the fully qualified class that will be updated (or created) which contains the IDs of the game resources. The format of the name is .. For example, AwesomeGame.GPGSIds

Paste the resource definition data. This is the XML data from the Google Play Developer Console which contains the resource IDs as well as the Application ID for Android.

This data is found in the Google Play Developer Console by clicking "Get resources" on any of the resource pages (e.g. Achievements or Leaderboards), then clicking Android.

After pasting the data into the text area, click the Setup button.

Note: If you are using a web application or backend server with your game, you can link the web application to the game to enable getting the player's id token and/or email address. To do this, link a web application to the game in the Google Play Developer Console, and enter the client id for the web application into the setup dialog.

Additional instructions on building for Android on Windows

If you are using Windows, you must make sure that your Java SDK installation can be accessed by Unity. To do this:

Set the JAVA_HOME environment variable to your Java SDK installation path (for example, C:\Program Files\Java\jdk1.7.0_45).
Add the Java SDK's bin folder to your PATH environment variable (for example, C:\Program Files\Java\jdk1.7.0_45\bin)
Reboot.

How to edit environment variables: In Windows 2000/XP/Vista/7, right-click My Computer, then Properties, then go to Advanced System Properties (or System Properties and then click the Advanced tab), then click Environment Variables. On Windows 8, press Windows Key + W and search for environment variables For more information, consult the documentation for your version of Windows.

Run the Project

If you are working with the Smoketest sample, you should be able to build and run the project at this point. You will see the automatic sign-in attempt, when Smoketest starts.

To build and run on Android, click File > Build Settings, select the Android platform, then Switch to Platform, then Build and Run.

ISocialPlatform Compliance

The Google Play Games plugin implements Unity's social interface, for compatibility with games that already use that interface when integrating with other platforms. However, some features are unique to Play Games and are offered as extensions to the standard social interface provided by Unity.

The standard API calls can be accessed through the Social.Active object, which is a reference to an ISocialPlatform interface. The non-standard Google Play Games extensions can be accessed by casting the Social.Active object to the PlayGamesPlatform class, where the additional methods are available.

Nearby Connections Configuration

In order to use nearby connections, a service id which uniquely identifies the set of applications that can interact needs to be configured. This is done by clicking the Window > Google Play Games > Nearby Connections setup... menu item. This will display the nearby connections setup screen. On this screen enter the service ID you want to use. It should be something that identifies your application, and follows the same rules as the bundle id (for example: com.example.myawesomegame.nearby). Once you enter the id, press Setup.

To use nearby connections, the player does not need to be authenticated, and no Google Play Developer Console configuration is needed.

For detailed information on nearby connection usage, please refer to nearby connections.

Sign in

A connection to Game services will be automatically formed when your game is opened. Once the connection is successful the player will be welcomed with a pop-up and your game is ready to begin using the Games Unity Plugin.

Note: If a user has never used Google Play Games on this device, they will be automatically taken through one-time setup operations such as creating a profile with the Play Games app.

In the Start method of your script, listen to the result of the automatic sign-in attempt, fetch the authentication status and disable Play Games Services features if the user is not signed in.

    using GooglePlayGames;

    public void Start() {
      PlayGamesPlatform.Instance.Authenticate(ProcessAuthentication);
    }

    internal void ProcessAuthentication(SignInStatus status) {
      if (status == SignInStatus.Success) {
        // Continue with Play Games Services
      } else {
        // Disable your integration with Play Games Services or show a login button
        // to ask users to sign-in. Clicking it should call
        // PlayGamesPlatform.Instance.ManuallyAuthenticate(ProcessAuthentication).
      }
    }
}

The result code is an enum, which gives you different failure reasons that will help you understand sign-in failures better.

If you prefer using Unity’s Social platform, then you can alternatively use the code block below.

  using GooglePlayGames;

  public void Start() {
    PlayGamesPlatform.Activate();
    Social.localUser.Authenticate(ProcessAuthentication);
  }

Note that you cannot make any games API calls (unlock achievements, post scores, etc) until you get a successful return value from Authenticate, so it is good practice to put up a standby screen until the callback is called, to make sure the user can't start playing the game until the authentication process completes.

Friends

Play Games Friends allows players to create and maintain a cross-games friends list. You can request access to this friends list to help your players play your game with their friends. See the Friends concept page for more details on the friends system.

To enable Friends, use the following functions:

View friends: Request access to a player’s friends list, so you can add their play games friends to your in-game friends list
View a player profile: Let a player view the Play Games profile of another player. This is essential so a player knows who their friends are, and can connect to other Play Games players in your game. This will need to be tied to a UI element to trigger the popup. See the friends guidelines for details.

See the best practices guidelines for instructions on how best to implement these APIs.

Note: To use Friends, you need to update your PGS SDK to version 20.0.0

View friends

There are two ways to load friends, either using the ISocial framework or directly with PlayGamesPlatform.

Loading friends with the ISocial framework

Social.localUser.LoadFriends((success) =>  {
    Debug.Log("Friends loaded OK: " + ok));
    foreach(IUserProfile p in Social.localUser.friends) {
         Debug.Log(p.userName + " is a friend");
    }

However, this call will fail if the current player has not yet granted permission to the game to access this information. Use GetLastLoadFriendsStatus to check if LoadFriends failed due to missing consent.

 PlayGamesPlatform.Instance.GetLastLoadFriendsStatus((status) => {
    // Check for consent
    if (status == LoadFriendsStatus.ResolutionRequired) {
        // Ask for resolution.
    }
});

A game can ask the current player to share the friends list by calling AskForLoadFriendsResolution.

PlayGamesPlatform.Instance.AskForLoadFriendsResolution((result) => {
    if (result == UIStatus.Valid) {
        // User agreed to share friends with the game. Reload friends.
    } else {
        // User doesn’t agree to share the friends list.
    }
});

This function will show the appropriate platform-specific friends sharing UI. This UI asks the player if they want to share their friends with the game.

Loading friends with PlayGamesPlatform

Another way of loading friends is to use LoadFriends and LoadMoreFriends:

PlayGamesPlatform.Instance.LoadFriends(pageSize, forceReload, (status) => {
    // Check if the call is successful and if there are more friends to load.
});

PlayGamesPlatform.Instance.LoadMoreFriends(pageSize, (status) => {
    // Check if there are more friends to load.
});

The pageSize param represents the number of entries to request for this page. Note that if cached data already exists, the returned buffer may contain more than this size. The buffer is guaranteed to contain at least this many entries if the collection contains enough records. If forceReload is set to true, this call will clear any locally-cached data and attempt to fetch the latest data from the server. This would commonly be used for actions like a user-initiated refresh. Normally, this should be set to false to gain the advantages of data caching.

If the callback returns LoadFriendsStatus.LoadMore, then there are more friends to load. LoadFriendsStatus.ResolutionRequired signals that the user has not shared the friends list and you can directly call PlayGamesPlatform.Instance.AskForLoadFriendsResolution.

Determining friends list visibility

Use PlayGamesPlatform.Instance.GetFriendsListVisibility to check if the user has shared the friends list with the game. Possible return statuses are:

FriendsListVisibilityStatus.RequestRequired indicates you must ask for consent.
FriendsListVisibilityStatus.Visible indicates that loading the friends list should succeed.
FriendsListVisibilityStatus.Unknown generally shouldn't happen. You can set forceReload to true to refresh the data.

PlayGamesPlatform.Instance.GetFriendsListVisibility(forceReload, (friendsListVisibilityStatus) => {});

View a player profile

To add or remove a player as a friend, use the show and compare profile function. This function triggers a bottom sheet dialog showing the Play Games profile of the user; call the function with the player Id of the requested player. If the player and friend have in-game nicknames, use them in the call to add more context to the profile UI:

PlayGamesPlatform.Instance.ShowCompareProfileWithAlternativeNameHintsUI(
    mFirstFriendId, /* otherPlayerInGameName= */ null, /* currentPlayerInGameName= */ null,
    (result) => {
        // Profile comparison view has closed.
});

Player Statistics

The Player Stats API let you tailor game experiences to specific segments of players and different stages of the player lifecycle. You can build tailored experiences for each player segment based on how players are progressing, spending, and engaging. For example, you can use this API to take proactive actions to encourage a less active player to re-engage with your game, such as by displaying and promoting new in-game items when the player signs in.

The callback takes two parameters:

The result code less than or equal to zero is success. See CommonStatusCodes for all values.
The PlayerStats object of type GooglePlayGames.PlayGamesLocalUser.PlayerStats

For more information see Player Stats.

The player stats are available after authenticating:

    ((PlayGamesLocalUser)Social.localUser).GetStats((rc, stats) =>
        {
            // -1 means cached stats, 0 is succeess
            // see  CommonStatusCodes for all values.
            if (rc <= 0 && stats.HasDaysSinceLastPlayed()) {
                Debug.Log("It has been " + stats.DaysSinceLastPlayed + " days");
            }
        });

Revealing/Unlocking an Achievement

To unlock an achievement, use the Social.ReportProgress method with a progress value of 100.0f:

    using GooglePlayGames;
    using UnityEngine.SocialPlatforms;
    ...
    // unlock achievement (achievement ID "Cfjewijawiu_QA")
    Social.ReportProgress("Cfjewijawiu_QA", 100.0f, (bool success) => {
      // handle success or failure
    });

Notice that according to the expected behavior of Social.ReportProgress, a progress of 0.0f means revealing the achievement and a progress of 100.0f means unlocking the achievement. Therefore, to reveal an achievement (that was previously hidden) without unlocking it, simply call Social.ReportProgress with a progress of 0.0f.

Incrementing an Achievement

If your achievement is incremental, the Play Games implementation of Social.ReportProgress will try to behave as closely as possible to the expected behavior according to Unity's social API, but may not be exact. For this reason, we recommend that you do not use Social.ReportProgress for incremental achievements. Instead, use the PlayGamesPlatform.IncrementAchievement method, which is a Play Games extension.

    using GooglePlayGames;
    using UnityEngine.SocialPlatforms;
    ...
    // increment achievement (achievement ID "Cfjewijawiu_QA") by 5 steps
    PlayGamesPlatform.Instance.IncrementAchievement(
        "Cfjewijawiu_QA", 5, (bool success) => {
            // handle success or failure
    });

Posting a Score to a Leaderboard

To post a score to a leaderboard, call Social.ReportScore.

    using GooglePlayGames;
    using UnityEngine.SocialPlatforms;
    ...
    // post score 12345 to leaderboard ID "Cfji293fjsie_QA")
    Social.ReportScore(12345, "Cfji293fjsie_QA", (bool success) => {
        // handle success or failure
    });

To post a score and include a metadata tag use the Play Game Services instance directly:

    using GooglePlayGames;
    using UnityEngine.SocialPlatforms;
    ...
    // post score 12345 to leaderboard ID "Cfji293fjsie_QA" and tag "FirstDaily")
    Social.ReportScore(12345, "Cfji293fjsie_QA", "FirstDaily", (bool success) => {
        // handle success or failure
    });

Note that the platform and the server will automatically discard scores that are lower than the player's existing high score, so you can submit scores freely without any checks to test whether or not the score is greater than the player's existing score.

Showing the Achievements UI

To show the built-in UI for all achievements, call Social.ShowAchievementsUI.

    using GooglePlayGames;
    using UnityEngine.SocialPlatforms;
    ...
    // show achievements UI
    Social.ShowAchievementsUI();

Showing the Leaderboard UI

To show the built-in UI for all leaderboards, call Social.ShowLeaderboardUI.

    using GooglePlayGames;
    using UnityEngine.SocialPlatforms;
    ...
    // show leaderboard UI
    Social.ShowLeaderboardUI();

If you wish to show a particular leaderboard instead of all leaderboards, you can pass a leaderboard ID to the method. This, however, is a Play Games extension, so the Social.Active object needs to be cast to a PlayGamesPlatform object first:

    using GooglePlayGames;
    using UnityEngine.SocialPlatforms;
    ...
    // show leaderboard UI
    PlayGamesPlatform.Instance.ShowLeaderboardUI("Cfji293fjsie_QA");

Accessing Leaderboard data

There are 2 methods to retrieving the leaderboard score data.

Using Social.ILeaderboard

This method uses the ILeaderboard interface to define the scope and filters for getting the data. This approach allows you to configure:

The leaderboard Id
The collection (social or public)
The timeframe (daily, weekly, all-time)
The rank position to start retrieving scores.
The number of scores (the default is 25).
Filter by user id.

If the from parameter is non-positive, then the results returned are player-centered, meaning the scores around the current player's score are returned.

    ILeaderboard lb = PlayGamesPlatform.Instance.CreateLeaderboard();
    lb.id = "MY_LEADERBOARD_ID";
    lb.LoadScores(ok =>
        {
            if (ok) {
                LoadUsersAndDisplay(lb);
            }
            else {
                Debug.Log("Error retrieving leaderboardi");
            }
        });

Using PlayGamesPlatform.LoadScores()

This method uses the PlayGamesPlatform directly. This approach provides additional flexibility and information when accessing the leaderboard data.

    PlayGamesPlatform.Instance.LoadScores(
            GPGSIds.leaderboard_leaders_in_smoketesting,
            LeaderboardStart.PlayerCentered,
            100,
            LeaderboardCollection.Public,
            LeaderboardTimeSpan.AllTime,
            (data) =>
            {
                mStatus = "Leaderboard data valid: " + data.Valid;
                mStatus += "\n approx:" +data.ApproximateCount + " have " + data.Scores.Length;
            });

The parameters for LoadScores() are:

leaderboardId
start position (top scores or player centered)
row count
leaderboard collection (social or public)
time span (daily, weekly, all-time)
callback accepting a LeaderboardScoreData object.

The LeaderboardScoreData class is used to return information back to the caller when loading scores. The members are: 1. Id - the leaderboard id 2. Valid - true if the returned data is valid (the call was successful) 3. Status - the ResponseStatus of the call 4. ApproximateCount - the approximate number of scores in the leaderboard 5. Title - the title of the leaderboard 6. PlayerScore - the score of the current player 7. Scores - the list of scores 8. PrevPageToken - a token that can be used to call LoadMoreScores() to get the previous page of scores. 9. NextPageToken - a token that can be used to call LoadMoreScores() to get the next page of scores.

    void GetNextPage(LeaderboardScoreData data)
    {
        PlayGamesPlatform.Instance.LoadMoreScores(data.NextPageToken, 10,
            (results) =>
            {
                mStatus = "Leaderboard data valid: " + data.Valid;
                mStatus += "\n approx:" +data.ApproximateCount + " have " + data.Scores.Length;
            });
    }

This call may fail when trying to load friends with ResponseCode.ResolutionRequired if the user has not shared their friends list with the game. In this case, use AskForLoadFriendsResolution to request access.

Getting player names

Each score has the userId of the player that made the score. You can use Social.LoadUsers() to load the player profile. Remember that the contents of the player profile are subject to privacy settings of the players.

    internal void LoadUsersAndDisplay(ILeaderboard lb)
    {
        // get the user ids
        List<string> userIds = new List<string>();

        foreach(IScore score in lb.scores) {
            userIds.Add(score.userID);
        }
        // load the profiles and display (or in this case, log)
        Social.LoadUsers(userIds.ToArray(), (users) =>
            {
                string status = "Leaderboard loading: " + lb.title + " count = " +
                    lb.scores.Length;
                foreach(IScore score in lb.scores) {
                    IUserProfile user = FindUser(users, score.userID);
                    status += "\n" + score.formattedValue + " by " +
                        (string)(
                            (user != null) ? user.userName : "**unk_" + score.userID + "**");
                }
                Debug.log(status);
            });
    }

Recording Events

Incrementing an event is very simple, just call the following method:

    using GooglePlayGames;
    ...
    // Increments the event with Id "YOUR_EVENT_ID" by 1
    PlayGamesPlatform.Instance.Events.IncrementEvent("YOUR_EVENT_ID", 1);

This call is "fire and forget", it will handle batching and execution for you in the background.

Saving Game State to the Cloud

For details on saved games concepts and APIs please refer to the documentation.

Displaying saved games UI

The standard UI for selecting or creating a saved game entry is displayed by calling:

    void ShowSelectUI() {
        uint maxNumToDisplay = 5;
        bool allowCreateNew = false;
        bool allowDelete = true;

        ISavedGameClient savedGameClient = PlayGamesPlatform.Instance.SavedGame;
        savedGameClient.ShowSelectSavedGameUI("Select saved game",
            maxNumToDisplay,
            allowCreateNew,
            allowDelete,
            OnSavedGameSelected);
    }


    public void OnSavedGameSelected (SelectUIStatus status, ISavedGameMetadata game) {
        if (status == SelectUIStatus.SavedGameSelected) {
            // handle selected game save
        } else {
            // handle cancel or error
        }
    }

Opening a saved game

In order to read or write data to a saved game, the saved game needs to be opened. Since the saved game state is cached locally on the device and saved to the cloud, it is possible to encounter conflicts in the state of the saved data. A conflict happens when a device attempts to save state to the cloud but the data currently on the cloud was written by a different device. These conflicts need to be resolved when opening the saved game data. There are 2 open methods that handle conflict resolution, the first OpenWithAutomaticConflictResolution accepts a standard resolution strategy type and automatically resolves the conflicts. The other method, OpenWithManualConflictResolution accepts a callback method to allow the manual resolution of the conflict.

See GooglePlayGames/BasicApi/SavedGame/ISavedGameClient.cs for more details on these methods.

    void OpenSavedGame(string filename) {
        ISavedGameClient savedGameClient = PlayGamesPlatform.Instance.SavedGame;
        savedGameClient.OpenWithAutomaticConflictResolution(filename, DataSource.ReadCacheOrNetwork,
            ConflictResolutionStrategy.UseLongestPlaytime, OnSavedGameOpened);
    }

    public void OnSavedGameOpened(SavedGameRequestStatus status, ISavedGameMetadata game) {
        if (status == SavedGameRequestStatus.Success) {
            // handle reading or writing of saved game.
        } else {
            // handle error
        }
    }

Writing a saved game

Once the saved game file is opened, it can be written to save the game state. This is done by calling CommitUpdate. There are four parameters to CommitUpdate:

the saved game metadata passed to the callback passed to one of the Open calls.
the updates to make to the metadata.
the actual byte array of data
a callback to call when the commit is complete.

    void SaveGame (ISavedGameMetadata game, byte[] savedData, TimeSpan totalPlaytime) {
        ISavedGameClient savedGameClient = PlayGamesPlatform.Instance.SavedGame;

        SavedGameMetadataUpdate.Builder builder = new SavedGameMetadataUpdate.Builder();
        builder = builder
            .WithUpdatedPlayedTime(totalPlaytime)
            .WithUpdatedDescription("Saved game at " + DateTime.Now());
        if (savedImage != null) {
            // This assumes that savedImage is an instance of Texture2D
            // and that you have already called a function equivalent to
            // getScreenshot() to set savedImage
            // NOTE: see sample definition of getScreenshot() method below
            byte[] pngData = savedImage.EncodeToPNG();
            builder = builder.WithUpdatedPngCoverImage(pngData);
        }
        SavedGameMetadataUpdate updatedMetadata = builder.Build();
        savedGameClient.CommitUpdate(game, updatedMetadata, savedData, OnSavedGameWritten);
    }

    public void OnSavedGameWritten (SavedGameRequestStatus status, ISavedGameMetadata game) {
        if (status == SavedGameRequestStatus.Success) {
            // handle reading or writing of saved game.
        } else {
            // handle error
        }
    }

    public Texture2D getScreenshot() {
        // Create a 2D texture that is 1024x700 pixels from which the PNG will be
        // extracted
        Texture2D screenShot = new Texture2D(1024, 700);

        // Takes the screenshot from top left hand corner of screen and maps to top
        // left hand corner of screenShot texture
        screenShot.ReadPixels(
            new Rect(0, 0, Screen.width, (Screen.width/1024)*700), 0, 0);
        return screenShot;
    }

Reading a saved game

Once the saved game file is opened, it can be read to load the game state. This is done by calling ReadBinaryData.

    void LoadGameData (ISavedGameMetadata game) {
        ISavedGameClient savedGameClient = PlayGamesPlatform.Instance.SavedGame;
        savedGameClient.ReadBinaryData(game, OnSavedGameDataRead);
    }

    public void OnSavedGameDataRead (SavedGameRequestStatus status, byte[] data) {
        if (status == SavedGameRequestStatus.Success) {
            // handle processing the byte array data
        } else {
            // handle error
        }
    }

Deleting a saved game

Once the saved game file is opened, it can be deleted. This is done by calling Delete.

    void DeleteGameData (string filename) {
        // Open the file to get the metadata.
        ISavedGameClient savedGameClient = PlayGamesPlatform.Instance.SavedGame;
        savedGameClient.OpenWithAutomaticConflictResolution(filename, DataSource.ReadCacheOrNetwork,
            ConflictResolutionStrategy.UseLongestPlaytime, DeleteSavedGame);
    }

    public void DeleteSavedGame(SavedGameRequestStatus status, ISavedGameMetadata game) {
        if (status == SavedGameRequestStatus.Success) {
            ISavedGameClient savedGameClient = PlayGamesPlatform.Instance.SavedGame;
            savedGameClient.Delete(game);
        } else {
            // handle error
        }
    }

Retrieving server authentication codes

In order to access Google APIs on a backend web server on behalf of the current player, you need to get an authentication code from the client application and pass this to your web server application. This code can then be exchanged for an access token to make calls to the various APIs. For more details on this flow see: Google Sign-In for Websites.

To get the server side access code:

Configure the web client id of the web application linked to your game in the Play Game Console.
Call PlayGamesPlatform.Instance.RequestServerSideAccess once the player is authenticated to get the server side access code.
Pass this code to your server application.

  PlayGamesPlatform.Instance.RequestServerSideAccess(
    /* forceRefreshToken= */ false,
    code -> {
      // send code to server
    });

Decreasing apk size

It is possible to decrease the size of the Play Games Services Unity Plugin by removing code for the Play Games Services features that your game doesn’t use by using Proguard. Proguard will remove the Play Games Unity plugin code for features that are not used in your game, so your game ships with only the code that is needed and minimizes the size impact of using Play Games Services.

Additionally, it is possible to reduce the size of the entire Unity project using Unity’s Managed Code Stripping, which will compress your entire project. This can be used in conjunction with Proguard.

Play Games Services Proguard configuration

Go to File > Build Settings > Player Settings and click Publishing Settings section. Choose Proguard for Minify > Release. Then, enable User Proguard File. If you want the plugin to be proguarded for debug apks as well, you can choose Proguard for Minify > Debug.
Copy the content of the proguard configuration into Assets/Plugins/Android/proguard-user.txt.

(Advanced) Using the Plugin Without Overriding the Default Social Platform

When you call PlayGamesPlatform.Activate, Google Play Games becomes your default social platform implementation, which means that static calls to methods in Social and Social.Active will be carried out by the Google Play Games plugin. This is the desired behavior for most games using the plugin.

However, if for some reason you wish to keep the default implementation accessible (for example, to use it to submit achievements and leaderboards to a different social platform), you can use the Google Play Games plugin without overriding the default one. To do this:

Do not call PlayGamesPlatform.Activate
If Xyz is the name of a method you wish to call on the Social class, do not call Social.Xyz. Instead, call PlayGamesPlatform.Instance.Xyz
Do not use Social.Active when interacting with Google Play Games. Instead, use PlayGamesPlatform.Instance.

That way, you can even submit scores and achievements simultaneously to two or more social platforms:

    // Submit achievement to original default social platform
    Social.ReportProgress("MyAchievementIdHere", 100.0f, callback);

    // Submit achievement to Google Play
    PlayGamesPlatform.Instance.ReportProgress("MyGooglePlayAchievementIdHere", 100.0f, callback);
