c# - AS3 Socket/服务器 MMO 通信

Question

我正在使用 c# 服务器开发 Flash MMO。我有一个简单的套接字消息传递协议(protocol)。当客户加入时，他会发出以下信息:

 "%|clientId|need"

职位更新如下:

 "$|clientId|xPosition|yPosition"

由于某种原因，这不起作用。我将所有头像存储在一个数组中，头像类只是扩展了movieclip。这应该将所有客户端添加到房间中，但它不起作用。有任何想法吗？

编辑:错误可能在上面的客户端代码中，我认为这与我将头像存储在数组中的方式有​​关。

这是我的代码:

id.text = String(Math.random());
import flash.net.Socket;
import flash.events.MouseEvent;
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.utils.Dictionary;

var avatars:Array = new Array();

 var _socket:Socket = new Socket();
 _socket.addEventListener(ProgressEvent.SOCKET_DATA,socketData);
 _socket.addEventListener(Event.CONNECT,socketConnected);
 _socket.addEventListener(IOErrorEvent.IO_ERROR,socketError);



_socket.connect("192.168.1.4",8000);

function sendText(msg:String):void {
 if (_socket.connected) {
  _socket.writeUTFBytes(msg);
  _socket.flush();

 } else {

 }
}

function socketConnected(e:Event):void {
 chat.appendText("Connected. \n");
 sendText("%|" + id.text + "|need");
 //chat.scrollV = chat.maxScrollV;
}

function socketError(e:IOErrorEvent):void {
 chat.appendText("SYSTEM MSG:"+e.text+"\n");
 //chat.scrollV = chat.maxScrollV;
}

function socketData(e:ProgressEvent):void {
 var str:String = e.currentTarget.readUTFBytes(e.currentTarget.bytesAvailable);
 trace(str);
 //var xml:XML = new XML(str);
 chat.appendText(str + "\n");
 //[pos]|50|334
 if(str.search("$")){
  var positionArray = str.split("|");
  avatars[str[1]].x = str[2];
  avatars[str[1]].x = str[3];
 }
 if(str.search("%")){
  var miniArray = str.split("|");
  avatars[miniArray[1]] = new Avatar();
  addChild(avatars[miniArray[1]]);
  dump.text = miniArray[1];
 }

}



me.addEventListener(MouseEvent.MOUSE_DOWN, drag);
me.addEventListener(MouseEvent.MOUSE_UP, sDrag);

var timing:Boolean = false;
var t:Timer = new Timer(1);
t.addEventListener(TimerEvent.TIMER, tick);

function tick(e:TimerEvent){
 if(timing){
  sendText('$|'+id.text+'|'+me.x+'|'+me.y);
 }
 else{
 }
}

t.start();


function drag(e:MouseEvent){
 me.startDrag();
 timing = true;
}

function sDrag(e:MouseEvent){
 me.stopDrag();
 timing = false;
}

编辑:根据其他信息更改答案。

解决代码后，您遇到了一些问题。首先是您使用 if(str.search)... $ 和 % 可以解析为正则表达式。此外，由于您的字符索引为 0，因此这些 if 可能不成立。最后，您使用的是 str[1] 而不是 positionArray[1] 等。下面是工作代码，在不使用套接字服务器的情况下进行了一些黑客测试。当您遇到此类问题时，可能会向您展示一些有关如何进行重点测试的技巧。
