如何在 Xamarin 中获取当前玩家的排行榜分数

Question

我需要增加当前玩家的排行榜分数。为了在java中做到这一点，我做了这样的事情：

PendingResult<Leaderboards.LoadPlayerScoreResult> result = Games.Leaderboards.loadCurrentPlayerLeaderboardScore(mGoogleApiClient,  getString(R.string.winsleaderboardid), LeaderboardVariant.TIME_SPAN_ALL_TIME, LeaderboardVariant.COLLECTION_PUBLIC);

if(result != null)
{
    result.setResultCallback(new ResultCallback<Leaderboards.LoadPlayerScoreResult>() {
        @Override
        public void onResult(Leaderboards.LoadPlayerScoreResult loadPlayerScoreResult) {
            if(loadPlayerScoreResult != null && loadPlayerScoreResult.getScore() != null)
            {
                Games.Leaderboards.submitScore(mGoogleApiClient, getString(R.string.winsleaderboardid), loadPlayerScoreResult.getScore().getRawScore() + 1);
            }
            else
            {                                 
                Games.Leaderboards.submitScore(mGoogleApiClient, getString(R.string.winsleaderboardid), 1);
            }
        }
   });
}

我似乎无法在 Xamarin 中找到 ILoadPlayerScoreResult 的接口，但我希望是这样的：

private async void IncrementLeaderBoardWins()
    {
        IResult result = await GamesClass.Leaderboards.LoadCurrentPlayerLeaderboardScore(
                    mGoogleApiClient, GetString(Resource.String.winsleaderboardid), Android.Gms.Games.LeaderBoard.LeaderboardVariant.TimeSpanAllTime,
                    Android.Gms.Games.LeaderBoard.LeaderboardVariant.CollectionPublic);

        OnResult(result);
    }

public void OnResult(ILoadPlayerScoreResult loadPlayerScoreResult)
{
    if (loadPlayerScoreResult != null && loadPlayerScoreResult.getScore() != null)
    {
        GamesClass.Leaderboards.SubmitScore(mGoogleApiClient, GetString(Resource.String.winsleaderboardid), loadPlayerScoreResult.getScore().getRawScore() + 1);
    }
    else
    {
        GamesClass.Leaderboards.SubmitScore(mGoogleApiClient, GetString(Resource.String.winsleaderboardid), 1);
    }
}

使用LoadCurrentPlayerLeaderboardScoreAsync 返回一个ILeaderboardsLoadPlayerScoreResult 与LoadCurrentPlayerLeaderboardScore，后者返回一个您需要等待和转换的IResult。

快速示例：

var myGamerID = "StackOverflowGamer";
var score = 9999;
var client = new GoogleApiClient.Builder(this).AddApi(GamesClass.API).AddScope(GamesClass.ScopeGames).Build();
client.BlockingConnect();
var result = await GamesClass.Leaderboards.LoadCurrentPlayerLeaderboardScoreAsync(client, "StackOverflowLeaderBoard", LeaderboardVariant.TimeSpanAllTime, LeaderboardVariant.CollectionPublic);
Console.WriteLine(result.Score);
GamesClass.Leaderboards.SubmitScore(client, myGamerID, score);
