Play Games Multiplayer 中的等候室不显示已连接的玩家

Question

我在我的一个游戏应用中使用了 Google Play 游戏服务的实时多人游戏支持。自动匹配配置是这样指定的：

Bundle autoMatchCriteria = RoomConfig.createAutoMatchCriteria(7, 7, 0);

因此它将创建一个有 6 名玩家的游戏。我现在有以下问题：

假设已经有 4 人连接到候诊室，那么他们就不会见面了。所以他们不知道其他人已经连接了。只有当所有 7 名参与者都连接时，才会显示玩家的姓名。这种行为不会促使人们在所有玩家都连接之前留在候诊室，因为对他们来说，这就像他们独自等待一样。

下图显示了候诊室。两个人已经连接，但玩家只能看到他们自己。当房间已满时，字符串 'auto-pick' 将被替换为玩家姓名，但为时已晚。

如何向玩家展示候车室的真实状态？我不想激励他们留在候诊室。

Gradle 依赖项：

dependencies {
implementation 'com.android.support:multidex:1.0.3'
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:mediarouter-v7:28.0.0'

implementation 'com.google.android.gms:play-services-auth:16.0.1'
implementation 'com.google.android.gms:play-services-ads:16.0.0'

这就是游戏的创建方式：

   void startQuickGame() {
    final int MAX_OPPONENTS = 6;
    int min_opponents = 6;
    Bundle autoMatchCriteria = RoomConfig.createAutoMatchCriteria(min_opponents,
            MAX_OPPONENTS, 0);
    RoomConfig.Builder rtmConfigBuilder = RoomConfig.builder(this);
    rtmConfigBuilder.setMessageReceivedListener(this);
    rtmConfigBuilder.setRoomStatusUpdateListener(this);
    rtmConfigBuilder.setAutoMatchCriteria(autoMatchCriteria);
    rtmConfigBuilder.setVariant(variant);
    switchToScreen(R.id.mpGamescreen_wait);
    keepScreenOn();

    Games.RealTimeMultiplayer.create(mGoogleApiClient, rtmConfigBuilder.build());
    }

上述方法startQuickGame();在onConnected(Bundle connectionHint)方法内部被调用。 onActivityResult 看起来像：

    @Override
public void onActivityResult(int requestCode, int responseCode, Intent intent) {
    super.onActivityResult(requestCode, responseCode, intent);

    switch (requestCode) {
        case RC_SELECT_PLAYERS:
            // we got the result from the "select players" UI -- ready to create the room
            handleSelectPlayersResult(responseCode, intent);
            break;
        case RC_WAITING_ROOM:
            // we got the result from the "waiting room" UI.
            if (responseCode == Activity.RESULT_OK) {
                // ready to start playing
                Log.d(TAG, "debug Starting game (waiting room returned OK).");
                //startGameHandler(true);
            } else if (responseCode == GamesActivityResultCodes.RESULT_LEFT_ROOM) {
                // player indicated that they want to leave the room
                leaveRoom();
            } else if (responseCode == Activity.RESULT_CANCELED) {
                // Dialog was cancelled (user pressed back key, for instance). In our game,
                // this means leaving the room too. In more elaborate games, this could mean
                // something else (like minimizing the waiting room UI).
                leaveRoom();
            }
            break;
        case RC_SIGN_IN:
            Log.d(TAG, "debug onActivityResult with requestCode == RC_SIGN_IN, responseCode="
                + responseCode + ", intent=" + intent);
            mSignInClicked = false;
            mResolvingConnectionFailure = false;
            if (responseCode == RESULT_OK) {
              mGoogleApiClient.connect();
            } else {
              BaseGameUtils.showActivityResultError(this,requestCode,responseCode, R.string.signin_other_error);
            }
            break;
    }
    super.onActivityResult(requestCode, responseCode, intent);
}

API 客户端在 oncreate 中是这样创建的。请注意，某些方法已被弃用（将来应切换到 GoogleSignIn）。

        // Create the Google Api Client with access to Plus and Games
    mGoogleApiClient = new GoogleApiClient.Builder(this)
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)
        //.addApi(Plus.API).addScope(Plus.SCOPE_PLUS_LOGIN)
        .addApi(Games.API).addScope(Games.SCOPE_GAMES)
        .build();

欢迎任何提示或解决方法。

您的 RoomStatusUpdate 监听器怎么样？ RoomStatusUpdateCallback 你实现了 onPeerJoined(Room room, List参与者Ids) 方法吗？
