This is the simplest and easiest WebSocket library for Unity you can find!
System.Net.WebSockets
)Requires Unity 2019.1+ with .NET 4.x+ Runtime

into your Assets
directory.using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using NativeWebSocket;
public class Connection : MonoBehaviour
{

// Start is called before the first frame update

};

{
Debug.Log("OnMessage!");
Debug.Log(bytes);
// getting the message as a string
// var message = System.Text.Encoding.UTF8.GetString(bytes);
// Debug.Log("OnMessage! " + message);
};
// Keep sending messages at every 0.3s
InvokeRepeating("SendWebSocketMessage", 0.0f, 0.3f);

await websocket.Connect();
}

{
#if !UNITY_WEBGL || UNITY_EDITOR
websocket.DispatchMessageQueue();
#endif
}
async void SendWebSocketMessage()
{
if (websocket.State == WebSocketState.Open)
{
// Sending bytes
await websocket.Send(new byte[] { 10, 20, 30 });
// Sending plain text
await websocket.SendText("plain text message");
}
}
private async void OnApplicationQuit()
{
await websocket.Close();
}
}
1. Start the local WebSocket server:
cd Server
npm install
npm start
2. Open the NativeWebSocket/Assets/WebSocketExample/WebSocketExampleScene.unity
on Unity and Run.
Big thanks to Jiri Hybek. This implementation is based on his work.
