Detect if LobbyServer goes online or offline

[devomage]

Detecting if a lobby server goes offline is available via checking the error string when TNLobbyClient.onChange fires...

How do you detect when the lobby server comes back online?  If the lobby server has 0 servers TNLobbyClient.onChange doesn't fire and 'errorString' remains "Unable to connect".

In this case:  I would expect onChange needs to fire and 'errorString' needs to be cleared.

Everything works fine if there are more than 0 servers connected to the lobby server... 

Edit:  errorString does not change from "Unable to connect" when 'list' changes from 0 to 1... not that it matters if list.size > 0 -- but still seems wonky that it's not cleared.

1. Lobby Server Status:  online with 0 servers
2.  
3. >>> Pressing play:
4.  
5. TNLobbyClient.onChange:
6. errorString = ""
7. isActive = True
8.  
9. >>> Stop remote lobby server:
10.  
11. TNLobbyClient.onChange:
12. errorString = "Unable to connect"
13. isActive = True
14.  
15. >>> Start remote lobby server:
16.  
17. TNLobbyClient.onChange: (doesnt fire, vars remain unchanged)
18. errorString = "Unable to connect"
19. isActive = True
20.

You can add errorString = ""; to TcpLobbyClient's Update function where it processes Disconnect and ResposneServerList packets.

1.                                         else if (response == Packet.Disconnect)
2.                                         {
3.                                                 knownServers.Clear();
4.                                                 isActive = false;
5.                                                 changed = true;
6.                                                 errorString = "";
7.                                         }
8.                                         else if (response == Packet.ResponseServerList)
9.                                         {
10.                                                 lock (knownServers.list) knownServers.list.Clear();
11.                                                 knownServers.ReadFrom(reader, time);
12.                                                 changed = true;
13.                                                 errorString = "";
14.                                         }
