Unity Android游戏可以使用Google Play游戏插件登录，但无法从排行榜加载分数

Question

在输入此问题之前，我进行了很多搜索（在此问题上停留了2周：'（），我的目标只是Unity项目中的Google页首横幅功能。我按照以下步骤操作：

1-集成的Google Play游戏插件，如以下网址所述： https : //github.com/playgameservices/play-games-plugin-for-unity

• 在我的Google Play开发者控制台中创建了一个Google Play服务游戏条目，并将其链接到我的应用程序（在同一控制台中），且其包ID为com.o6systems.zray，处于开放式Alpha测试状态。
• 我创建了凭据，并将密钥库/密钥对的SHA1插入到Google api控制台。
• 我创建了成就，1个记分牌，并将资源输入到Window / GooglePlayGames / Setup / Android设置中

我使用的密钥库与生成SHA1代码的密钥库相同。 我在播放器设置及其密码中输入了它。

我的软件包名称在所有平台上都是一致的（在Google api控制台，google play开发者控制台，在任何地方都统一）

我在控制台中将测试用户输入到测试用户。

2-我在启动画面场景中的脚本之一中输入了以下验证代码：

void Start () {
        #if UNITY_ANDROID
        ConfigureGooglePlay ();
        SignIn ();
        #endif
}

void ConfigureGooglePlay(){

            PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder()
                .Build();
            PlayGamesPlatform.InitializeInstance(config);
        PlayGamesPlatform.DebugLogEnabled = true;
        PlayGamesPlatform.Activate();
}

void SignIn () {
        Social.localUser.Authenticate (success => {
            if (success) {
                Debug.Log ("Authentication successful");
                string userInfo = "Username: " + Social.localUser.userName +
                                  "\nUser ID: " + Social.localUser.id +
                                  "\nIsUnderage: " + Social.localUser.underage;
                Debug.Log (userInfo);

            //  DisplayGPScore();
            } else
                Debug.Log ("Authentication failed");
        });
    }

3-在游戏场景中，在游戏结束时，我使用ReportScore功能将用户的高分发布到排行榜

private void OnGameOver(){
        ...
        PostScore(_gm.highScore);
        ..

        DisplayGPScore ();
    }

    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) {
                    Debug.Log("" + score.rank + ":" + score.userID); 

                }
                Debug.Log(status);
            });
    }

public void DisplayGPScore(){

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

public void PostScore(int score){
        PlayGamesPlatform.Instance.ReportScore(score, ZRayGameManager.WORLD_LEADERBOARD_ID, (bool success) => {

            if(success){
                Debug.Log("High score " + score + " posted");
            }else{
                Debug.Log("High score " + score + " could not be posted");

            }

        });

    }

我简化了代码（不相关的部分除外）

我得到以下输出

结论：

1. 用户可以进行身份​​验证，因为方法Sign In（）告知身份验证成功并打印出用户信息。

2. 用户可以将他/她的分数发布到计分板上，因为PostScore方法显示“已发布高分100”

3. 用户无法显示计分板分数，错误为

W /团结（15970）：!!! [Play游戏插件DLL] 07/17/16 18:47:10 +03：00警告：fetchScoreSummary返回的错误：GooglePlayGames.Native.PInvoke.FetchScor eSummaryResponse

我在控制台中找不到计分板的任何设置，无法授予用户对此计分板的访问权限等。

请帮忙！！ 我在这里停留了2周（但是有所改善，我无法在3天前登录）

Answer 1

要显示页首横幅，您需要调用startActivityForResult并传递意图以创建默认的页首横幅UI。 在以下代码段中， REQUEST_LEADERBOARD是请求代码的任意整数。

startActivityForResult(Games.Leaderboards.getLeaderboardIntent(mGoogleApiClient,
LEADERBOARD_ID), REQUEST_LEADERBOARD);

要获得玩家的分数：

Private void loadScoreOfLeaderBoard() {
Games.Leaderboards.loadCurrentPlayerLeaderboardScore(getApiClient(), getString(R.string.your_leaderboard_id), LeaderboardVariant.TIME_SPAN_ALL_TIME, LeaderboardVariant.COLLECTION_PUBLIC).setResultCallback(new ResultCallback<Leaderboards.LoadPlayerScoreResult>() {
@Override
public void onResult(final Leaderboards.LoadPlayerScoreResult scoreResult) {
if (isScoreResultValid(scoreResult)) {
// here you can get the score like this
mPoints = scoreResult.getScore().getRawScore();
}
}
});
}

private boolean isScoreResultValid(final Leaderboards.LoadPlayerScoreResult scoreResult) {
return scoreResult != null && GamesStatusCodes.STATUS_OK == scoreResult.getStatus().getStatusCode() && scoreResult.getScore() != null;
}

SIGN_OUT status: ERROR_NOT_AUTHORIZED

确保您拥有正确的SHA1指纹 。 由于与Google Play服务集成，因此Android上的授权请求与其他授权工作流程不同。

使用OAuth 2.0访问Google API时，所有应用程序都遵循基本模式。 在较高的级别，您遵循四个步骤：

• 从Google API控制台获取OAuth 2.0凭据。
• 从Google授权服务器获取访问令牌。
• 将访问令牌发送到API。
• 如有必要，刷新访问令牌。
