Starcraft UDP

[Archangel]

What have to be done to connect to a Starcraft Game Host?

[UserLoser.]

First step would not be connecting, nor would any of them.  Hope this helps

[Archangel]

Well, so, the steps of joining a Starcraft Game?

[DeTaiLs]

Packet log u joining a game and do a search i remember sombody posting the broken down packet telling u what does what

[Archangel]

I already packet logged, but i dont know if im doing something wrong:
Would be: Send 0x09 - Requesting 19 users
Recieve - 0x09 - With the 19 users.

Click a game:
Request 0x09 - Requesting game info by the name.
Recieven - 0x09

Get Host and IP

Then use UDP?
UDP.Connect Host, Port

Well, i suppose thats wrong, because it not works for me..

[DeTaiLs]

here is some hope this helps

1. Game speed
2. Game type
3. Game penalty
4. Map icon
5. Map size
6. Timestamp of some sort
7. ?
------------------------------------

Game speed goes as follows:
0 = slowest
1 = slower
2 = slow
3 = normal
4 = fast
5 = faster
6 = fastest
none = default (ladder uses this, default=fast)

------------------------------------
Game type goes as follows:
2 = Melee
3 = Free for all
4 = 1 on 1
9 = Ladder
A = Use Map Settings
F = Top vs. Bottom

------------------------------------
Penalty goes as follows:
1 = no penalty on disconnected
2 = loss on disconnect

------------------------------------
Map icons go as follows:
1 = Blue Blizzard Checkmark Icon
2 = Ladder Map Icon
3 = Green GF icon
4 = KBK challenger icon
none = default (no icon)

------------------------------------
Map size goes as follows:

a) You take the number (34).
b) You take the first number (3) and multiply it by 32
c) 3 * 32 = 96

d) You take the second number (4) and multiply it by 32
e) 4 * 32 = 128

f) Your map size is now 96x128

summary:  your number is 34. (3 * 32) x (4 * 32) = 96x128

isnt that creating game?
k, thats not the problem i have, the problem is i dont know when to use the UDP, after doing what? or recivieng what?...

[Kp]

Use the UDP (or any other Force) when the time is right.  In this case, when you have the IP address and port of a game which you wish to join.  Send a hail, wait for a response, then indicate to the host that you wish to join his game.

[Archangel]

ok, you need to enable UDP before connecting to bnet? or after?
you need to connect UDP to the bnet server?
then? if you do? what fucntion to connect host? [VB]

[Kp]

In order: no, no, no (it doesn't make any sense), not applicable, not applicable, and UDP isn't connection-oriented, which you'd know if you'd read udp(7).

[Archangel]

kk, then, when i connect to bnet i bind the udp:
        .sckUDP.RemoteHost = IP
        .sckUDP.RemotePort = 6114
        .sckUDP.Bind 6114

im supposed to send 3 times 0x09, but i dont understand at all, how i am supposed to recive an answer?
