从 Google Play 服务、Unity 插件获取所有回合制比赛信息答案

【问题标题】：Get All TurnBased Matches Info from GooglePlayServices, Unity Plugin从 Google Play 服务、Unity 插件获取所有回合制比赛信息
【发布时间】：2015-04-19 09:19:33
【问题描述】：

我使用 TicTacToss 代码作为 Unity 中基于 android 的回合制游戏的基础，使用以下代码：https://github.com/playgameservices/play-games-plugin-for-unity

一切都运行良好，但没有任何功能可以返回当前用户正在参与、活跃和完成的游戏列表。我需要将它用于主 UI，这样我就可以向用户展示他们正在玩什么游戏、与谁玩等等。如果没有，这个 API 似乎很缺乏。

有没有人能够做到这一点？在我看来，功能可能在那里，因为有一个名为 GetAllTurnbasedMatches() 的函数，但我的 C# 不够强大，无法理解它是如何工作的。（见https://github.com/playgameservices/play-games-plugin-for-unity/blob/master/source/PluginDev/Assets/GooglePlayGames/Platforms/Native/PInvoke/TurnBasedManager.cs）

【解决方案1】：

我设法将以下内容添加到 NativeTurnBasedMultiplayerClient.cs：

public void GetAllTBMatches(Action<TurnBasedMatch, TurnBasedMatch.MatchTurnStatus> callback)
{
    mTurnBasedManager.GetAllTurnbasedMatches(allMatches =>
    {
        foreach (var match in allMatches.MatchesMyTurn())
        {
            var converted = match.AsTurnBasedMatch(mNativeClient.GetUserId());
            Logger.d("MY turn : Passing converted match to user callback:" + converted);
            callback(converted, TurnBasedMatch.MatchTurnStatus.MyTurn);
        }
        foreach (var match in allMatches.MatchesTheirTurn())
        {
            var converted = match.AsTurnBasedMatch(mNativeClient.GetUserId());
            Logger.d("Their Turn : Passing converted match to user callback:" + converted);
            callback(converted, TurnBasedMatch.MatchTurnStatus.TheirTurn);
        }
        foreach (var match in allMatches.MatchesCompleted())
        {
            var converted = match.AsTurnBasedMatch(mNativeClient.GetUserId());
            Logger.d("Completed : Passing converted match to user callback:" + converted);
            callback(converted, TurnBasedMatch.MatchTurnStatus.Complete);
        }

        callback(null, TurnBasedMatch.MatchTurnStatus.Unknown);
    });
}

public void GetAllTBInvitations(Action<Invitation> callback)
{
    mTurnBasedManager.GetAllTurnbasedMatches(allMatches =>
    {
        foreach (var invitation in allMatches.Invitations())
        {
            var converted = invitation.AsInvitation();
            Logger.d("Passing converted invitation to user callback:" + converted);
            callback(converted);
        }

        callback(null);
    });
}

您还需要在 TurnBasedManager.cs 中编辑以下内容

internal class TurnBasedMatchesResponse : BaseReferenceHolder {
    internal TurnBasedMatchesResponse(IntPtr selfPointer) : base(selfPointer) {
    }

    protected override void CallDispose(HandleRef selfPointer) {
        C.TurnBasedMultiplayerManager_TurnBasedMatchesResponse_Dispose(SelfPtr());
    }

    internal CommonErrorStatus.MultiplayerStatus Status() {
        return C.TurnBasedMultiplayerManager_TurnBasedMatchesResponse_GetStatus(SelfPtr());
    }

    internal IEnumerable<MultiplayerInvitation> Invitations()
    {
        return PInvokeUtilities.ToEnumerable(
            C.TurnBasedMultiplayerManager_TurnBasedMatchesResponse_GetInvitations_Length(SelfPtr()),
            index => new MultiplayerInvitation(C.TurnBasedMultiplayerManager_TurnBasedMatchesResponse_GetInvitations_GetElement(SelfPtr(), index)));
    }

    internal IEnumerable<NativeTurnBasedMatch> MatchesMyTurn()
    {
        return PInvokeUtilities.ToEnumerable(
            C.TurnBasedMultiplayerManager_TurnBasedMatchesResponse_GetMyTurnMatches_Length(SelfPtr()),
            index => new NativeTurnBasedMatch(C.TurnBasedMultiplayerManager_TurnBasedMatchesResponse_GetMyTurnMatches_GetElement(SelfPtr(), index)));
    }

    internal IEnumerable<NativeTurnBasedMatch> MatchesTheirTurn()
    {
        return PInvokeUtilities.ToEnumerable(
            C.TurnBasedMultiplayerManager_TurnBasedMatchesResponse_GetTheirTurnMatches_Length(SelfPtr()),
            index => new NativeTurnBasedMatch(C.TurnBasedMultiplayerManager_TurnBasedMatchesResponse_GetTheirTurnMatches_GetElement(SelfPtr(), index)));
    }

    internal IEnumerable<NativeTurnBasedMatch> MatchesCompleted()
    {
        return PInvokeUtilities.ToEnumerable(
            C.TurnBasedMultiplayerManager_TurnBasedMatchesResponse_GetCompletedMatches_Length(SelfPtr()),
            index => new NativeTurnBasedMatch(C.TurnBasedMultiplayerManager_TurnBasedMatchesResponse_GetCompletedMatches_GetElement(SelfPtr(), index)));
    }

    internal static TurnBasedMatchesResponse FromPointer(IntPtr pointer)
    {
        if (PInvokeUtilities.IsNull(pointer)) {
            return null;
        }

        return new TurnBasedMatchesResponse(pointer);
    }
}
