[C#] Sending Packet

[xTrion]

Hello

i want to send a move Packet to the game Nova Raider. I already sniffed the Packet (was pretty easy, because they are not encoded). So i send the Packet and the Packet shows up in WireShark. But nothing happens ingame.

The sniffed Packet:

 Spoiler

{\"data\":{\"qid\":\"27\",\"data\":{\"x\":\"40\",\ "x0\":\"42\",\"y\":\"8\",\"y0\":\"9\",\"time\":\"1 34\"},\"method\":\"POST\"},\"sid\":\""+sid[1] + "\",\"uri\":\"/rest/mainship/move\"}"

My function to send the Packet:

 Spoiler

            int PORT_NO = Port;
            string SERVER_IP = Server;

            TcpClient client = new TcpClient(SERVER_IP, PORT_NO);
            NetworkStream nwStream = client.GetStream();
            byte[] bytesToSend = ASCIIEncoding.ASCII.GetBytes(_data);

            rtB.Invoke((MethodInvoker)delegate
            {
                rtB.Text += Environment.NewLine + "Sending : " + _data;
           });

            nwStream.Write(bytesToSend, 0, bytesToSend.Length);

            byte[] bytesToRead = new byte[client.ReceiveBufferSize];
            int bytesREad = nwStream.Read(bytesToRead, 0, client.ReceiveBufferSize);
            rtB.Invoke((MethodInvoker)delegate
            {
                rtB.Text += Environment.NewLine + "Received : " + Encoding.ASCII.GetString(bytesToRead, 0, bytesREad);
            });

            client.Close();

You have to use the clients connection if you want to see the client affected.

Don't make a new connection, you have to use the asm send function for your packet emission

[UniveX']

Either use the game connection or make a proxy, make the game use the proxy and modify the packets however you want, since you said they are not encrypted, it shouldn't be a problem, at all.
