Question

我正在尝试使用Google Play游戏在Android中编写多人游戏。一切都适用于自动匹配，但我无法弄清楚如何决定何时开始邀请游戏。

我的网络管理员有一个像这样的shouldStartGame（）函数：

boolean shouldStartGame(Room room) 
{
    int connectedPlayers = 0;
    for (Participant p : room.getParticipants()) {
        if (p.isConnectedToRoom()) ++connectedPlayers;
    }
    return connectedPlayers >= this.totalRequestedPlayers;
}

当游戏是自动匹配游戏时，这很好 - 当选择玩家对话框返回时，totalRequestedPlayers会填充onActivityResult

public void onActivityResult(int request, int response, Intent data) {
if (request == NetworkManager.RC_SELECT_PLAYERS)
{
final ArrayList<String> invitees = data.getStringArrayListExtra(Games.EXTRA_PLAYER_IDS);

// get auto-match criteria
Bundle autoMatchCriteria = null;
int minAutoMatchPlayers = data.getIntExtra(Multiplayer.EXTRA_MIN_AUTOMATCH_PLAYERS, 0);
int maxAutoMatchPlayers = data.getIntExtra(Multiplayer.EXTRA_MAX_AUTOMATCH_PLAYERS, 0);

if (minAutoMatchPlayers > 0) 
{
    autoMatchCriteria = RoomConfig.createAutoMatchCriteria(
            minAutoMatchPlayers, maxAutoMatchPlayers, 0);
} 
else 
{
    autoMatchCriteria = null;
}

this.oNetwork.setTotalRequestedPlayers(invitees.size() + minAutoMatchPlayers);
RoomConfig roomConfig = roomConfigBuilder.build();
Games.RealTimeMultiplayer.create(getApiClient(), roomConfig);

// prevent screen from sleeping during handshake
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

然而，当响应来自其他玩家的邀请开始比赛时，我找不到任何询问房间或configBuilder的方法来找出需要多少玩家...

protected void onCreate(Bundle _savedState)
{   
String invitationID=this.getIntent().getExtras().getString(NetworkManager.EXTRA_ROOM_ID);
if(invitationID.equals(""))
{
    //invite some people
    this.oNetwork.beginInviteFriends(); 
}
else
{
//we have been invited to a room
    RoomConfig.Builder roomConfigBuilder =
            this.oNetwork.makeStandardRoomConfigForGameType(this);
    roomConfigBuilder.setInvitationIdToAccept(invitationID);

    RoomConfig c = roomConfigBuilder.build();

    this.oNetwork.setTotalRequestedPlayers(999);  // <-  need to figure out how to get this info
    Games.RealTimeMultiplayer.join(getApiClient(), c);

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}
}

我需要找出被命名的＆＃39;的总数。来自原始邀请的玩家，加上自动匹配请求的数量

功能

@Override
public void onRoomConnected(int arg0, Room _room)
{

}

告诉您所有被邀请或自动匹配的用户是否已连接到会议室。
