I'm working on client-server-client game. Client is sending their status (position) 30 times a second. I'm using Lidgren.Network namespace for networking (server, client).

I've got two questions:

1. is: Is there a way to get whole NetIncomingMessage without manually using message.ReadString(), message.ReadInt32(), etc?

Second is a problem. On my local computer, everything works all right, position is updating fine and there are no Error Messages appearing. However, when on Linux (Using MONO on Linux side to run my server application (console appliaction)) on the remote box, I'm getting strange errors about once a second.

Received wrong pong number; got 56 expected 59 (ErrorMessage)
Received wrong pong number; got 57 expected 59 (ErrorMessage)
Received wrong pong number; got 58 expected 59 (ErrorMessage)

Googling this gave me only link to source code

Actual code taken right from source code of the Lidgren library which is giving me an error

// verify it´s the correct ping number
if (pingNumber != m_lastSentPingNumber)
{
      m_owner.LogDebug("Received wrong pong number; got " + pingNumber + " expected " + m_lastSentPingNumber);
      return;
}

possible problems:

  • Mono
  • Packet loss (which I think is more probably, but on the other side, I think this shouldn't happen as I use NetDeliveryMethod.ReliableOrdered)

For everyone interested, there's how I actually send the user's position

message.Write((byte)commandType.MOVE);
message.Write(Base.game.player.x);
message.Write(Base.game.player.y);
Client.SendMessage(message, NetDeliveryMethod.ReliableOrdered); // yes, ReliableOrdered, so I think it should loss any packets, should it?

are you sure you are expecting correct number of bytes? I mean two ints plus a byte will result in 9 bytes, where did you get 59 from? – Gajoo Jan 26 '12 at 20:29
@Gajet: It's still increasing, it's starting from 5, before that, I actually send CONNECT byte, player username, x & y before sending this frequently) – Martin. Jan 26 '12 at 20:32
Why did you pick ReliableOrdered? – Joshua Drake Apr 26 '12 at 12:33
@Joshua because it has to be shooter game, and I think that needs to be accurate – Martin. Apr 26 '12 at 13:42
Makes sense to me, but I think that it may be part of the problem. Since you chose Ordered but the packets are not being received that way. – Joshua Drake Apr 26 '12 at 13:46
