Socket.emit不起作用，但socket.broadcast确实

Question

由于某种原因，socket.emit不会运行，也不知道错误在哪里。但是socket.broadcast工作。

 io.sockets.on('connection', function (socket) { // on on client connection
        socket.on('login', function (uname, pword, email) { // on event login
            SetupPlayer(socket);
        });
    });

这是一个名为

的函数

var SetupPlayer= function(socket){
    GetPlayer(socket, function(PlayerObj){
        GetQuests(socket, function(QuestObj){
            socket.room = PlayerObj.RoomID;
            socket.emit('PlayerStructure', PlayerObj, QuestObj); // notify other clients about new player also passing players daya using set data structure
            socket.broadcast.in(socket.room).emit('AddPlayer', activeusers[socket.room][socket.id]); // same as above
        });
    });  
}

然而，socket.emit没有任何结果，socket.broadcast.in(socket.room).emit确实在运行

这是客户代码，但不认为这是问题所在。

socket.on('AddPlayer', function(playerstructure) {
    console.log(playerstructure);
});
socket.on('PlayerStructure', function(playerstructure) {
    console.log(playerstructure);
});
