Hi,

You cann't build a Unity3d Web Player Release, the reason for this is the Security Sand Box of the Web Player (see http://docs.unity3d.com/Manual/SecuritySandbox.html).

The following error message appears when you try to build your Unity3d project on the Web Player Platform:
ArgumentException: The Assembly System.Runtime.Serialization is referenced by SimpleJson. But the dll is not allowed to be included or could not be found....
SimpleJson is using Reflections these won't be supported by the Web Player Subset.

At the moment I'm trying to replace the SimpleJson.dll with the SimpleJSON from the Unify Community (http://wiki.unity3d.com/index.php/SimpleJSON). Maybe someone of you could give me some feedback to this decision and/or maybe someone comes up with an other idea.

Best Regards

Flo

I ended it up with error bug. Don't know exactly how to use. Sorry if can, please anyone leave me a small project. Thanks!

i have problem to use this.

when i try to emit to server, sometimes it's not call callback func.
( only application. test in editor, server send message ordinarily(pc))

why is that ?

服务器端使用Nodejs，前端使用unity3d，界面使用NGUI，通信用的unitysocketio,当我接收到服务器端返回的信息时，需要更新页面数据，但是报错了

TrySetSetString can only be called from the main thread.
Constructors and field initializers will be executed from the loading thread when loading a scene.
Don't use this function in the constructor or field initializers, instead move initialization code to the Awake or Start function.

向大家请教如何处理这个问题，是否是线程的问题还是其它的？

I narrowed down the problem to the thread using dequeuOutboundMessages. It eats more than 100% of a cpu core. Just this thread alone connected to a Node.js server which sends a message once in a while. Once a minute or less.

Hi there,

I've been playing with new socket.io 1.0.4 server side, but the current UnitySocketIO client cannot connect. It did work properly with version 0.9 of socket.io server.

Please consider to upgrade UnitySocketIO client to compatible with new socket io 1.x.

Many thanks

Hi Everyone,
I am working on video stream of a camera of a device in unity, here everything is give for how to start client can any give me hint how to start the server where this client send and receive data.
I am beginner in the this fields . So looking for your help.
Thanks in advance.

现在socket.io出到1.4.5了

Because i can't handshake with the server.

Hi,

I created a socket io server like this:

var io = require('socket.io').listen(5000);

io.sockets.on('connection', function (socket)
{
io.sockets.emit('evt', { foo: 'bar'});
});

and a pomelo client like this

using UnityEngine;
using System;
using System.Collections;
using SimpleJson;
using pomeloUnityClient;

public class TargetController : MonoBehaviour
{
private PomeloClient pclient = null;

void Start()
{
    string url = "http://localhost:5000";
    pclient = new PomeloClient(url);
    pclient.init();

    pclient.On("evt", (data)=>{
        Debug.Log("received something");
    });

    JsonObject emptyMessage = new JsonObject();
    emptyMessage.Add ("foo", "bar");

    pclient.notify("connection", emptyMessage);
}

}

and when I run the client part the server side logs this:

debug - client authorized
info - handshake authorized BPbGYLLp1TfVeVOaKZAD

And on unity client part I get nothing, zero, no error, warnings, logs, nothing.

Can you help me find out what is missing?

Ty,

We're stuck with a serious issue on iOS in that it is not able to send messages to a server (running node.js with socket.io). It receives without problems, and the very same code works for other platforms (both sending and receiving).

Anyone out there who can help with this would be highly appreciated.

private void SocketOpened(object sender, MessageEventArgs e)

should be

private void SocketOpened(object sender, EventArgs e)

we are using this plugin for multiplayer game and from last 3 days we found socket connection issue in Reliance JIO carrier in India
i am doing socket connection but socket is not connected to that server for JIO carrier rest carrier it works fine
so can you please help out for same to resolve
as we have try to connect with socket io version 2 and version 3 both
but not works

awaiting for response

Thanks

Hi,
I have been looking for the source code of the SimlpeJSON.dll over the internet , but the project seems to have updated as the latest project on http://simplejson.codeplex.com/ has namespace as Simple.Json, where as the one that has been in this project has namespace SimpleJson.SimpleJson.
Can you share the source of the dll that is used in this project ?

Thanks
Neerav
EDIT: I am new to GitHub , hence do not know how to post a question, please feel free to change it accodingly.

Hello, using M.VC#2010 Express the compiler drops an error with a duplicate dll function reference:

Error   49  The type 'System.Collections.Concurrent.ConcurrentQueue<T>' exists in both 'C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\mscorlib.dll' and 'C:\Games\Unity\UnitySocketIO-master\SocketIO\bin\Debug\SuperSocket.ClientEngine.Core.dll' C:\Games\Unity\UnitySocketIO-master\SocketIO\socketio\Client.cs 24  11  SocketIO

any idea how to fix this?

when i tried to connect to secure https server "error initializing handshake" connection is given. The server administrator gave the following as javascript method to connect

socket = io.connect('https://abcd.com:321010', {secure: true});

but the in socketio the client constructor takes only one argument, the url.How can we pass this second parameter while connecting? or in general how to connect with secure server??

thanks in advance

This library does work with Socket.io greater than v0.9. The current version is now up to v1.1. Please consider releasing an update.

When running socket in long polling mode, eg:

sio.configure(function() {
sio.set("transports", ["xhr-polling"]);
sio.set("polling duration", 10);
});

I get the following socket debug message, and none of the messages are received by Unity:

info - handshake authorized WOsMURlFxbhuWDH0Ac0c
warn - unknown transport: "websocket"

Is this a matter of changing the UnitySocketIO settings, or is xhr-polling currently not supported?

客户端使用的是UnitySocketio与服务器进行通信，与pomelo-unitychat (https://github.com/NetEase/pomelo-unitychat) 一样是基于U3D与NodeJS的项目。
但是服务器端没有用Pomelo,只是单纯的Nodejs，客户端使用UnistySocketIO。
在Unity中开发是能够正常与服务器连接，接收数据，但是打包之后就连接不上服务器。打包成什么格式都不能连接服务器。经过几次尝试之后，我很认真地参考了pomelo-unitychat，就是socket那部分，pomelo-unitychat使用PomeloClient，我的项目使用的是UnitySocketIO。
我把pomelo-unitychat运行起来的效果如下：

我做了一个测试Demo和我的项目写法是一样的，地址如下：

Hi. I'm writing a project in Unity4 and I'd love to use your great library to connect with a socket.io server but I'm running into some problems.

In Javascript I would usually write something like:

var socket = io.connect(url);
socket.emit(my_event, {my : 'data'} );

In C# (In Unity/MonoDevelop) I'm writing something like:

socket = new Client(url);
socket.Connect();
socket.Send(???)

Problems:

1. I'm getting lots of non-descript errors in the console on connection even though it tells me it has connected (I'm doing a Console.log(e.Message))
   socket error: SocketIOClient.Messages.EventMessage
   socket opened
   socket error: SocketIOClient.Messages.ConnectMessage
   (note: this also seems to keep retrying in the background even after I stop running the Unity game, and sometimes ends in a freeze/crash)
2. I have no idea how to send the (my_event, {my : 'data'} ) combination to socket.io as the 'Send' method of the Client class only takes a single argument. Do I need to join the two arguments as a single piece of JSON somehow?

Thanks for any help you can share - it would be super appreciated!
(or any examples would be great?)

Thanks (and congratulations!)
Phil

大家好，我遇到的问题是这样的：

客户端采用Unity3D，并利用UnitySocketIO和Node.js服务器通讯。在Unity3D编辑器中测试一切都正常，但编译为iOS版本后，发现可以建立连接，却无法发送消息。错误信息如下：

Can't figure out how to connect to a specific namespace.
Should be like this: http://localhost:8080/admin.

In client.cs, "using System.Collections.Concurrent;" is available in c# 4.0, not compatible with unity.

It seems that I can connect only to URLs containing IP addresses. It does handshaking successfully but after that just waits in "connecting" state forever.

For example if I try to connect ro 127.0.0.1:3700 it works, localhost:3700 doesn't.
Tried to connect to a remote server by host name — doesn't work.

Works fine on OS X.

When I tried create a new socket by doing same as how API done,It cames:
Here is my code ,just same as api:https://github.com/NetEase/UnitySocketIO

void Start () {
    string url = "http://192.168.199.128:5500";
    client = new Client(url);
    client.Opened += SocketOpened;
    client.Message += SocketMessage;
    client.SocketConnectionClosed += SocketConnectionClosed;
    client.Error += SocketError;
    client.Connect();
}

private void SocketError(object sender, ErrorEventArgs e)
{
    Debug.Log(e.Message);
}

private void SocketConnectionClosed(object sender, EventArgs e)
{
    Debug.Log(e);
}

private void SocketMessage(object sender, MessageEventArgs e)
{
    Debug.Log(e.Message);
}

private void SocketOpened(object sender, EventArgs e)
{
    Debug.Log("Socket Connected!");
}

My Server is running at a VMWare machine.

And the Unity print:

Could you help?Thanks!

Is this library cross platform? Will it work with Unity3D running on OSX? Thanks

I am struggling to get this working, I only received "handshake authorized" in my server, and socket opened event does not fire.

Server:

io.sockets.on('connection', function(socket) {
    console.log("-- Socket connected!");
    socket.emit("message", "Welcome fagget!");
});

Unity client:

        client = new Client("http://localhost:1337");
        client.Opened += SocketOpened;
        client.Message += SocketMessage;
        client.SocketConnectionClosed += SocketConnectionClosed;
        client.Error += SocketError;

        Debug.Log("Client set up, connecting..");

        client.On("message", data =>
        {
            Debug.Log("Message received!");                         
        });

        client.Connect();

i see you mention net 4.0 in your introduction.Since Unity3d use net2.0 build android, so i wonder it works for mobile platform?
forgive me, my english is not very good.

Hey there!

Thanks for making this interesting library. I've noticed you solved the "emit" problem, but the libraries have not been rebuilt. It worked just fine when I re-built them, but the current "bin/debug" is outdated.

Just putting this here in case anybody still has issues with emit. If someone can update the repo, that would probably help a few users (The ones who don't feel comfortable building them) with their problems.

Thanks!
(I'd update them myself but I figure one of the authors doing it is faster than a pull request.)

I cant seem to emit Events on my SocketIO node-js server. The Emit function doesnt seem to do anything.

I have seen some examples from pomelo clients but they use a custom protocol which SocketIO Servers dont recognize...So why is this called a SocketIO library ? Its a Websocket library using a custom protocol imo.

I can recieve Events in Unity with my own custom EventHandler, but i cant send Messages to the server.

Any help appreciated, the pomelo examples dont help me though, its a custom binary protocol.

Here is my code

using UnityEngine;
using SimpleJson;
using SuperSocket;
using WebSocket4Net;
using SocketIOClient;


public class test : MonoBehaviour{

    // Use this for initialization

    Client client = new Client("http://localhost:3998");

    void Start () {
        client.Opened += SocketOpened;
        client.Connect();
    }

    void SocketOpened(object sender, MessageEventArgs e){
        Debug.Log("connected");
    }

    // Update is called once per frame
    void Update () {

    }
}

This is my Error:

http://i.imgur.com/9NIwqhz.png

想知道为什么？？

I was following 'How to use' :

private void SocketMessage (object sender, MessageEventArgs e) {
if ( e!= null && e.Message.Event == "message") {
string msg = e.Message.MessageText;
process(msg);
}
}

But e.Message.Event is Null except if we use socket.send(string) on server.

socket.emit('loveall',{love:'emitting love'}) on server side gives null and not 'loveall' as event.

I am aware of the event handling from other issue posts, is this connected to that?
without this i need to parse the whole messagetext to get the event name.Please help
if i am doing any wrong.

Hello sir, I am an jr.Android Developer and created a socket.io client side with java. So I think you know there is v1 or v2 in client side for java. My problem is that my company use v3 in server side so I have to use v2 client (highest version in java) but I cant connect to their server. So I need to a v3 or higher server side url for test my client side for check the problem is in my side or in server side. Do you know any v3 or higher server?

Note: When I switch to v1 in client I can easly connect to other v2 servers.

Unless i'm interpreting the example wrong, I have:

"void Start () {
MyClient = new Client("http://95.232.201.42:35352"); //Custom Port
MyClient.Message += SocketMessage;
MyClient.Opened += SocketOpened;
MyClient.SocketConnectionClosed += SocketConnectionClosed;
MyClient.Error += SocketError;

    MyClient.Connect();
}

"

The socket server doesn't detect the connection, and I know it works because I've had it work with other utilities.
Either i'm not giving the correct URi/URL or this is too outdated.

        string eventName,
        Action<IMessage> action)
    {
        this.registrationManager.AddOnEvent(eventName, action);
    }

Good evening, I've tried to use the library and I am able to output the message and parse it but if I want to operate on GameObjects. Unity won't let me because the callback function is not operation from the main thread.
Has anyone found a solution?
Cheers,
Roger
