cocos2dx-js socket.io

cocos2d-x JavaScript
#1

Hi guys i am implementing a simple chat in my app using socket io…
i was able to connect to my server and emit an event. but when i build it in a native platform(exe/android)
i can still connect to the server but when i emit an event my server does not response any idea?

i thought that it is already fixed in 1.x version of socket.io

socket.io version is v1.3.7
and here is my code

in my cocos2d app

var TestScene= cc.Scene.extend({
    onEnter:function () {
        this._super();
        // connect to my node.js server
        var io = Socket.connect("localhost:3000");
         // this will send a chat message event to my server
        io.emit('chat message','a message from cocos2d!');
    }
});

in my server side (app.js)

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

app.get('/', function(req, res){
      res.sendFile(__dirname + '/index.html');
});

io.on('connection', function(socket){
    console.log("a socket connection stablished");
      socket.on('chat message', function(msg){
         console.log("chat message :"+msg);// not working on native build but working in web version
      });
});

http.listen(3000, function(){
      console.log('listening on *:3000');
});

it does not console.log my message from native build of my cocos app

I faced the same problem, I think that, function emit didn’t work.
@pandamicro and @Zinitter, please help us, thanks u:)

#3

@Pantoo

I don’t know about socket.io.
So i try summon other guys see if they can help.

@ZippoLag @thomasjab @grimfate

Any experiences or solutions on socket.io?

Thanks.

#4

they said that they updated socket.io on git, but when i try and update my cocos installation, it does emit except on android platform…

is it just an issue on jsb?

#5

@Pantoo i already make it running with the new beta version of cocos2dx…

cocos2d version : 3.9beta0
socket.io version : 1.3.6

if your gonna deploy on android the server must be running online
my server is running at c9.io its a cloud based IDE that supports nodes apps its a great tool for testing :smile:

#6

thanks u somuch, It ran successfully :smiley:

#7

@Pantoo
hahah just register a free account and create a new work space with a node js project then
it will create a sample chat app node js project for you and to run it just click the play button on the toolbar or alt+F5
its really simple… its just another editor except only its running on your browser online…

its no differ running a node on your local computer… hehe :blush:

Hi, I am new to network programming. I saw there is socketio.js in the supporting files of cocos2d framework when i create a new project. is there any step by step tutorial for how to create a simple 2 player online game for html5 platform using cocos2d js only?

#11

sorry sir @josprachi

i havent see any tutorial but they have a sample at the test folder

and you should add “socketio” in your project.json first

#12

All you have to do is go to : SocketIO.cpp file and
change
_separator = “:”;

to
_separator = “”;

#13

Can you please clarify this?
Adding socketio in project.json?
Where to add?

var SocketIO = SocketIO || window.io;

This line throws error for me.
Where is SocketIO defined?

#14

inlcude socket io first in your project.json
the io object is windo.io
declare a reference to it only when your using it…
the line var SocketIO = SocketIO || window.io; means that if SocketIO is undefined it will get window.io if not SocketIO is returned.

#15

Dear Pantoo,

Please help me !

I have a problem with socket.io - cocos2d-js.

Can you tell me example code or configuration.

Thanks so much !

#16

what ur problem?

#17

Deer Pantoo,

io.connect(“ip:port”)

When i write above code, it always timeout . 20 seconds later, it auto reconnect.

Can you share to me some example code to use socket.io, please !

Thanks so much !
