I've created this library as a Hobby project when I was experimenting with Unity. I haven't used Unity for over 2 years and I'm not able to maintain the repo. If you want to become a maintainer a keep this project running, send me an e-mail or create an issue. Thank you for understanding.
Hybrid event-driven WebSocket implementation for Unity 3D.
It automatically compiles browser or native implementation based on project's target platform. Native implementation is using WebSocketSharp library (must be downloaded separately - see below). For the browser implementation the custom emscripten JSLIB is used.
Warning: WebSocket client is intended to support only binary messages. So if you want to send or receive string messages you must convert it to/from byte array in your code.
You can get WebSocketSharp.dll from NuGet package manager. See NuGet Gallery: websocket-sharp.
Library can be installed manually. Just download the NuGet package. Then rename the file extension from .nupkg to .zip and extract it. Now you can copy lib/websocket-sharp.dll file to your Unity project into the Assets/Plugins directory.
For more info please visit official WebSocketSharp GitHub repo.
To install this plugin just copy the contents of Plugins directory to your Unity project's Assets/Plugins directory.
For example usage see Scripts/WebSocketDemo.cs file. You can import it to your project and assign it to any GameObject. Then run your project and check the console.
using System.Collections;
using System.Collections.Generic;
using System.Text;
using UnityEngine;
// Use plugin namespace
using HybridWebSocket;
public class WebSocketDemo : MonoBehaviour {
// Use this for initialization
void Start () {
// Create WebSocket instance
WebSocket ws = WebSocketFactory.CreateInstance("ws://echo.websocket.org");
// Add OnOpen event listener
ws.OnOpen += () =>
{
Debug.Log("WS connected!");
Debug.Log("WS state: " + ws.GetState().ToString());
ws.Send(Encoding.UTF8.GetBytes("Hello from Unity 3D!"));
};
// Add OnMessage event listener
ws.OnMessage += (byte[] msg) =>
{
Debug.Log("WS received message: " + Encoding.UTF8.GetString(msg));
ws.Close();
};
// Add OnError event listener
ws.OnError += (string errMsg) =>
{
Debug.Log("WS error: " + errMsg);
};
// Add OnClose event listener
ws.OnClose += (WebSocketCloseCode code) =>
{
Debug.Log("WS closed with code: " + code.ToString());
};
// Connect to the server
ws.Connect();
}
// Update is called once per frame
void Update () {
}
}When any error occours during method call then the WebSocketException is thrown. Unified both for native and browser client so you can catch it in your C# code.
