javascript - Socket.io emits to non-existing room -

i'm writing game , using socket.io. every map in game represented room in socket.io.

it works this. user runs client , joins main room (lobby) empty room "" in socket.io, there, user can create room, roomid number, starting 0 (0,1,2,3, etc). when user joins room, starts timer - countdown till end of current map.

 __starttimer:function() {     this.__timerid=setinterval(this.__ontimertick.bind(this), 1000); },  __ontimertick:function() {     var string="timer event in room "+this.__roomid+", list of socket.io rooms:";     console.log(string);     console.log(g.socketio.sockets.manager.rooms);      this.__duration--;     g.socketio.sockets.in(this.__roomid).emit(g.messages.fight_timer_tick_event, {time: this.__duration});     if(this.__duration==0)     {         clearinterval(this.__timerid);         this.__fightend();     } }, 

the problem that, when users close client, leaves room, , if there no more users in room, destroyed. when user runs client again, joins lobby, socket.io starts emitting timer event lobby room. emiting wrong room.

log:

i think problem in this: "starting 0". dont use 0 room name.
