ive started to work on d1 udp and was wondering if somone could enlighten me with some information. I need to know what the packet format for a udp packet is and what is included in it. thanks for any help.

I posted about that earlier. I didn't give the packet format, but listed what's in it. Class, command, sequence numbers (run per class), player id, flags, checksum, among other things.

to simply get into a game with other people what things do i need to include in the udp packets to join a game and what packets are required to get into the game/how many?

Try packet logging your self joining a game, come back and share the results and maybe we can help

I don't remember exactly, but something like 10-20 different packets. Apart from the ones that you just keep sending all the time.

i have a d1 ingame bot somewhat working,for some reason the bot sends the data to the host client and the host client responds but the packets are never recieved by my bot. here is how i setup the socket


Form1.d1udp.RemotePort = port
Form1.d1udp.RemoteHost = ip
Form1.d1udp.LocalPort = 6112


any ideas?

i packet logged the bot sending the data and the host revieving the data and sending the responds but the bot never gets them. and they are on seperate comps.

Try adding:


form1.d1udp.Bind


didn't help

didn't help

make sure it's set for udp protocall.
and if your behind a router set the local port to an open one.

if i chage the port my bot listens to in the program how does the host know what port to send the data too?

i just started d1 at the same time as my bot,i started a game and packet logged d1 then i tried to join my other comps game with my bot and the other comp sent the responds to d1 instead of my bot,but even when d1 isn't running my bot still doesn't get the responds,any ideas?

i think i figured it out,thanks for help anyways

for anyone thats actually got ingame in d1 on a bot could you tell me how close this is to getting in and anything im doing wrong/missing
