Socket.IO Client Library for Unity (mono / .NET 2.0), which is ported from the JavaScript client version 1.1.0.
SocketIoClientDotNet by Quobject is a very good project, but it does not support Unity. So I spent a few overnights to port it to mono/.NET 2.0.
Now game developers can:
- use node.js to develop game server, enjoy the powerful ecosystem of network and database, easily deploy to cloud;
- use Unity to develop game client, enjoy the poweful game engine and IDE.
- use websocket / socket.io to communicate between server/client.
Downlaod socket.io.unitypackage and then import into Unity.
Or, only download the following files in Lib and put to Unity project:
- WebSocket4Net.dll
- SocketIoClientDotNet.dll
- Newtonsoft.Json.dll
It's available on Unity Asset Store for $10, but you can also download it for FREE here.
If you are interested to dig into the source code, welcome to fork the SocketIoClientDotNet for .NET 2.0.
socket.io client for Unity has a similar api to those of the JavaScript client.
using Quobject.SocketIoClientDotNet.Client;
var socket = IO.Socket("https://localhost:3000");
socket.On(Socket.EVENT_CONNECT, () =>
{
socket.Emit("hi");
});
socket.On("hi", (data) =>
{
Debug.Log(data);
socket.Disconnect();
});
And, with Newtonsoft.Json.dll, we can easliy serialize / deserialize json object. Read more about Newtonsoft.Json.
This library supports all of the features the JS client does, including events, options and upgrading transport.
Mono, .NET 2.0
