【问题描述】：

我们想使用 google play 游戏在 Unity 中备份/恢复我们的 android 游戏。为此，我们使用play-games-plugin-for-unity 。使用 github 中引入的 ShowSelectUI() 方法，用户可以手动删除保存的游戏。现在的问题是我们想在 UI 中提供一个按钮，通过单击用户可以删除保存的游戏，有没有办法以编程方式进行删除操作？提前致谢。

如果您知道要删除的已保存游戏实例的名称，则可以调用 Open，然后在获得 savedData 的元数据后，调用 Delete：

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

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

我最终按照上面的@claytonWilkinson 实现了这个。然后我添加了 DeleteGoogleCloudSave() 来点击一个按钮：

public void DeleteGoogleCloudSave(){
    #if UNITY_ANDROID && !UNITY_EDITOR
    Debug.Log("Opening save...");

    if (isGooglePlayGamesConnected()){
        ((PlayGamesPlatform)Social.Active).SavedGame.OpenWithAutomaticConflictResolution("Filename", GooglePlayGames.BasicApi.DataSource.ReadCacheOrNetwork,ConflictResolutionStrategy.UseLongestPlaytime, DeleteSavedGameOpened);
    }
    #endif
}

void DeleteSavedGameOpened(SavedGameRequestStatus status, ISavedGameMetadata meta)
{
    #if UNITY_ANDROID && !UNITY_EDITOR

    Debug.Log("Running SaveGameOpened...");

    if(status == SavedGameRequestStatus.Success)
    {
       DeleteSavedGame();
    }
    #endif
}

void DeleteSavedGame() {
    ISavedGameClient savedGameClient = PlayGamesPlatform.Instance.SavedGame;
    savedGameClient.OpenWithAutomaticConflictResolution("Filename", DataSource.ReadCacheOrNetwork,ConflictResolutionStrategy.UseLongestPlaytime, OnDeleteSavedGame);
}

public void OnDeleteSavedGame(SavedGameRequestStatus status, ISavedGameMetadata game) {
    ISavedGameClient savedGameClient = PlayGamesPlatform.Instance.SavedGame;
    if (status == SavedGameRequestStatus.Success) {
        // delete the game.
        savedGameClient.Delete(game);
        Debug.Log("Google Cloud Save Game has been deleted...");
    } else {
        // handle error
        Debug.LogError("Google Cloud Save Game has NOT been deleted...");
    }
}
