Game Protocol FAQ

How are the news.txt and map checksums computed?

They both use a CRC32 algorithm. The popular zlib library has these functions.

Why do I get disconnected for no data?

Once you have entered an arena you must send position packets regularly to stay connected.

Why do I sometimes get two position packets with the same timestamp?

Chances are you got two 0x05 weapon packets or one 0x05 weapon and a 0x28 position. It is possible to fire a weapon right after the client has just sent a position.

Can I get LVZ by using the VIE protocol?

Yes, but you can either get all the LVZ, or none. You do not have a choice when it comes to optional LVZ. This currently only works on ASSS. See Game Protocol's login packet.
