Unity/websocket

websocket-sharpを使う

websocket-sharpをDL

git clone https://github.com/sta/websocket-sharp.git
ls websocket-sharp/websocket-sharp.sln

websocket-sharpをビルドする

1. ruby2.0以上を入れる
2. brew install mono
3. Example〜Example4を削除しwebsocket-sharp.slnないのExampleも削除する

$ xbuild websocket-sharp.sln

1. 以下が作成されることを確認

websocket-sharp/bin/Debug/websocket-sharp.dll

サーバ側websocketをインストール&起動

インストール

$ npm install -g ws

server.js作成

var WebSocketServer = require('ws').Server;
  , wss = new WebSocketServer({port: 9001})
  , connects        = [];
wss.on('connection', function(ws) {
      connects.push(ws);
      ws.on('message', function(message) {
                console.log('received: %s', message);
                broadcast(message);
      });
      ws.on('close', function () {
          console.log('stopping client send "close"');
          connects = connects.filter(function (conn, i) {
            return (conn === ws) ? false : true;
          });
      broadcast('connected sockets: ' + connects.length);
      });
      // ws.send('something');
});
function broadcast (message) {
   connects.forEach(function (socket, i) {
       socket.send(message);
   });
}

起動

$ node server.js

websocket(unity側)

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using WebSocketSharp;
public class WebSocketScript : MonoBehaviour {
	WebSocket ws;
	void Start () {
		this.ws = new WebSocket ("ws://localhost:9001");
		this.ws.OnMessage += (object sender, MessageEventArgs e) => {
			Debug.Log (e.Data);
		};
		this.ws.Connect ();
		GameObject.Find("SendButton").GetComponent<Button>().onClick.AddListener(OnClickSend);
		GameObject.Find("CloseButton").GetComponent<Button>().onClick.AddListener(OnClickClose);
	}
	void OnClickSend() {
		this.ws.Send (System.DateTime.Now.ToString ());
	}
	void OnClickClose() {
		this.ws.Close ();
	}
}
