【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。

【参考方案1】：

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
    

【参考方案2】：

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...");
