Socket.io遊戲。如何添加新字符

我是使用Socket.io編寫遊戲的，我有問題，當服務器創建新的img（新字符）時，我只能在一臺計算機上看到它。我想在這種情況下，對於每個連接計算機上看到更好的圖像相同數量的，如果你看看這個感謝每個幫助Socket.io遊戲。如何添加新字符

SERVER：

var handler = function(req, res) { 
    fs.readFile('./index.html', function (err, data) { 
     if(err) throw err; 
     res.writeHead(200); 
     res.end(data); 
    }); 
} 
var app = require('http').createServer(handler); 
var io = require('socket.io').listen(app); 
var fs = require('fs'); 
var port = 3250; 

app.listen(port); 
var postacie = []; 
var ile=0; 

// socket.io 
io.sockets.on('connection', function (socket) { 
    postacie[ile]=createChar(); 
    ile++; 
    io.sockets.emit("tworz", postacie); 


    socket.on("disconnect", function() 
    { 
     postacie.splice(0, 1); 
     io.sockets.emit("tworz", postacie); 
    }) 

}); 


function createChar() 
{ 
    var postac = { 
     src: "http://img703.imageshack.us/img703/1416/2st.gif", 
     id: "character" 
    } 
    return postac; 
}

我重構你的代碼位。希望它可以幫助您在正確的方向移動：

主要思想是用3個基本信息：

加盟 - 當新的客戶端連接服務器發送信息關於新手到所有其他客戶端;
list - 當新客戶端連接服務器時，向他發送已連接的客戶端列表;
休假 - 當有人斷開連接斷開連接客戶端的服務器發送ID

服務器：

var handler = function(req, res) { 
    fs.readFile('./index.html', function (err, data) { 
     if(err) throw err; 
     res.writeHead(200); 
     res.end(data); 
    }); 
} 

var app = require('http').createServer(handler); 
var io = require('socket.io').listen(app); 
var fs = require('fs'); 
var port = 3250; 

app.listen(port); 
var postacie = []; 
var idGenerator = 0; 

// socket.io 
io.sockets.on('connection', function (socket) { 
    var pId = idGenerator++; 
    socket.emit("list", postacie); 

    var postac = createChar(pId); 
    postacie.push(postac); 
    io.sockets.emit("join", postac); 

    socket.on("disconnect", function() 
    { 
     var sId = "character" + pId; 
     for (var i = 0,n=postacie.length; i < n; ++i) { 
      var postac = postacie[i]; 
      if (postac.id == sId) { 
       io.sockets.emit("leave", {id:postac.id}); 
       postacie.splice(i, 1); 
       break; 
      } 
     } 
    }); 

}); 


function createChar(id) 
{ 
    var postac = { 
     src: "http://img703.imageshack.us/img703/1416/2st.gif", 
     id: "character" + id 
    }; 
    return postac; 
}
