package com.socket {
    import flash.display.Sprite;
    import flash.external.ExternalInterface;
    import flash.text.TextField;
    import flash.utils.ByteArray;

    import com.pnwrain.flashsocket.FlashSocket;
    import com.pnwrain.flashsocket.events.FlashSocketEvent;


    class client extends Sprite {
        public var socket:FlashSocket;

        public function client() {
            FlashSocket.debug = true;

            var url:String = "http://50.98.142.22:2048/";
            trace("connecting to: " + url);

            socket = new FlashSocket(url);

            socket.addEventListener(FlashSocketEvent.CONNECT, function(e:FlashSocketEvent):void {
                trace("connected");

                trace("sending request openlobby");
                socket.emit('openlobby', function(testS:String):void {
                    trace('openlobby: got back string:' + testS);
                });
            });

            socket.addEventListener('returntest', function(e:FlashSocketEvent):void {
                var s:String = e.data[0];
                trace("we have recieved" + s);
            })

            socket.addEventListener(FlashSocketEvent.DISCONNECT, function(e:FlashSocketEvent):void {
                trace("disconnect");
            });
            socket.addEventListener(FlashSocketEvent.SECURITY_ERROR, function(e:FlashSocketEvent):void {
                trace("security error");
            });
            socket.addEventListener(FlashSocketEvent.CONNECT_ERROR, function(e:FlashSocketEvent):void {
                trace("connect error");
            });
            socket.addEventListener(FlashSocketEvent.IO_ERROR, function(e:FlashSocketEvent):void {
                trace("io error");
            });
            socket.addEventListener(FlashSocketEvent.ERROR, function(e:FlashSocketEvent):void {
                trace("error");
            });
        }
