UDP接続がlanで動作しない

Question

私はクライアントとサーバをプロジェクトに設定していますが、ネットワーク上のコンピュータ間で接続していません。

クライアント：

public class GameClient extends Thread { 

private static Image image; 

private InetAddress ipAddress; 
private DatagramSocket socket; 
private Play play; 

public GameClient(Play play, String ipAddress){ 
    this.play = play; 

    try { 
     this.socket = new DatagramSocket(); 
     this.ipAddress = InetAddress.getByName(ipAddress); 
    } catch (SocketException e) { 
     e.printStackTrace(); 
    } catch (UnknownHostException e) { 
     e.printStackTrace(); 
    } 

} 

public GameClient(Play play, InetAddress ipAddress){ 
    this.play = play; 

    try { 
     this.socket = new DatagramSocket(); 
     this.ipAddress = ipAddress; 
    } catch (SocketException e) { 
     e.printStackTrace(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

} 

public void run() { 
    //boolean run = true; 
    while(true) { 
     byte[] data = new byte[1024]; 
     DatagramPacket packet = new DatagramPacket(data, data.length); 
     try { 
      socket.receive(packet); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

     this.parsePacket(packet.getData(), packet.getAddress(), packet.getPort()); 
    } 
} 

public static void getImage(Image newImage){ 
    image = newImage; 
} 

private void parsePacket(byte[] data, InetAddress address, int port) { 
    String message = new String(data).trim(); 
    PacketTypes type = Packet.lookupPacket(message.substring(0, 2)); 
    Packet packet = null; 
    switch (type) { 
    default: 
    case INVALID: 
     break; 
    case LOGIN: 
     packet = new Packet00Login(data); 
     System.out.println("[" + address.getHostAddress() + ":" + port + "] " + ((Packet00Login)packet).getUsername() + " has joined the game"); 
     PlayerMP player = new PlayerMP(((Packet00Login)packet).getUsername(), (double)200, (double)200, 65, 285, (float)0, (double)1, image, address, port); 

     play.addEntity(player); 
     play.setClientPlayer(player); 
     break; 
    case DISCONNECT: 
     packet = new Packet01Disconnect(data); 
     System.out.println("[" + address.getHostAddress() + ":" + port + "] " + ((Packet01Disconnect)packet).getUsername() + " has left the world..."); 
     play.removePlayerMP(((Packet01Disconnect)packet).getUsername()); 
     break; 
    case MOVE: 
     packet = new Packet02Move(data); 
     handleMove((Packet02Move) packet); 

    } 
} 

public void sendData(byte[] data){ 
    DatagramPacket packet = new DatagramPacket(data, data.length, ipAddress, 1331); 
    try { 
     socket.send(packet); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
} 

private void handleMove(Packet02Move packet){ 
    this.play.movePlayer(packet.getUsername(), packet.getX(), packet.getY(), packet.getDirection()); 
} 

}

明らかに、このプログラムは1台のコンピュータで動作し、ipの外観は正しい（192.0.0.XXX）しかし、私が1台のコンピュータでサーバを稼働させて、もう1台のコンピュータでサーバを稼動させないようにすると、2台目のコンピュータは最初のコンピュータに接続しません。

ありがとうございます！

ネットワークをうまくやってくれることは何でもありました。Pは、私が誤ってクライアントではなく情報を送信するためにサーバーを直接呼び出すことが判明しました。私は最初にやっていたはずだったように、サーバーを新しいプロジェクトに移動し、スタンドアロンとしてセットアップしました。しかし、助けてくれてありがとう！
