Question

我正在使用socketio制作游戏服务器存储玩家数量，当游戏开始时为2，游戏开始但是，当我逐个打开两个浏览器时，只有第一个（不是后一个）接收游戏开始消息客户方：

var socket = io.connect('http://localhost:8080');
socket.on('connected', function (data) {
    $('#status').html('You are connected');
    socket.emit('1 party connected');
});

socket.on('game start', function (data) {
    $('#status').html('game start');
});

服务器端：

var app = require('http').createServer(handler)
  , io = require('socket.io').listen(app)
  , fs = require('fs')

app.listen(8080);

var connected_parties_no = 0;

io.sockets.on('connection', function (socket) {
  socket.emit('connected', { hello: 'world' });
  socket.on('1 party connected', function () {
    connected_parties_no++;
    console.log(connected_parties_no.toString()+' parties are connecting.');
    if (connected_parties_no == 2) {
      game_start(socket);
    }
  });
  socket.on('disconnect', function () {
    connected_parties_no--;
  });
});

function game_start(socket) {
  socket.broadcast.emit('game start');
}

Answer 1

socket.broadcast.emit('game start');

会将'game start'事件发送给除`socket之外的所有人。你最有可能找

io.sockets.emit('game start');

socketio广播消息只发送给一个
