【问题描述】：

我需要一些有关 SmartFox 服务器的帮助。

ISFSGameApi gameAPI = SmartFoxServer.getInstance().getAPIManager().getGameApi();
        List<User> invitees = new ArrayList<User>();
        invitees.add(invitee);

        CreateSFSGameSettings settings = new CreateSFSGameSettings();
        settings.setMaxUsers(2);
        settings.setMaxVariablesAllowed(5);
        settings.setGame(true);
        settings.setInvitationExpiryTime(waitingTime);
        settings.setMinPlayersToStartGame(2);
        settings.setName("rm-" + sender.getName());
        settings.setDynamic(true);
        settings.setLeaveLastJoinedRoom(false);
        settings.setAutoRemoveMode(SFSRoomRemoveMode.WHEN_EMPTY);
        settings.setInvitedPlayers(invitees);

        try 
        gameAPI.createGame(getParentExtension().getParentZone(), settings, sender);
         catch (SFSCreateRoomException e) 
            // TODO Auto-generated catch block
            e.printStackTrace();
        

在执行上述代码作为扩展时，我遇到了这个错误。任何想法都值得赞赏。我对java不太熟悉。谢谢

我的猜测是这与邀请有关，我追踪了“被邀请者”及其用户，还追踪了其他变量并且工作正常。

【参考方案1】：

改变了

settings.setMinPlayersToStartGame(2);

到

settings.setMinPlayersToStartGame(1);

而且效果很好。看起来还是很奇怪。我猜。希望它可以帮助某人。
