Receiving 0x0F event EID_INFO in a Starcraft game

[Tazo]

When I create a game using Starcraft, if someone joins my game, I receive 0x0F, event 0x12 (EID_INFO). It contains the user's record.

0070   3a 00                                            :.

For some reason, if I create a game using my bot, I never receive 0x0F, and I have no way to tell if people are even joining my games. I have only tested this joining my own game using another bot. If I perform a /who on the bots, both appear to be in the game, but my "host" bot is never notified. I have no trouble starting a game using my "host" bot after I have sent my other bot in the game, even though I was never even notified of the join.

Does Starcraft do something special to request stats from the server that my bot isn't? I didn't notice anything in the packetlog.

when someone joins games your client sends /astat name

Ah, ok. I did not see it in my packetlog.

How is the client notified that someone has joined? UDP?

eh? it sends /astat to the battle.net server and receives 0x0f EID_INFO response.

Err, sorry haha, edited my post a few seconds too late. I meant how is the client notified that someone joins? How does it know to send /astat? That's mainly what I'm looking for here.

yes it's notified through this UDP message:

which is kinda weird cause the statstring is received there..

Cool, thanks

Unfortunately, I'm not sure exactly what the client does to get the server to send it this message - I tried sending PKT_CONNTEST2 when logging on, exactly how client does (server token, udp value), but I still don't receive a UDP message when someone joins. Oh well.

consider checking your create game packet, maybe you're telling the server the wrong port to which clients should send udp too or something similar
