Any ideas on how this is calculated?  Is it a SHA hash (like logins)?  I've not spent too much time trying to do gamebots, but I've been interested in making a bot so you can chat in-game for a while now.  Just wondering if anyone knew, if not I'll just try my best at figuring it out.

Also, for the 4th part, what if it's an unapproved map, I assume it's just "blnk" (blank)?

Offhand, can you post a map statstring?  I'm at work.  Although, I would observe that it should be easy to tell if it's SHA or otherwise.  SHA is 128-bit, IIRC.  If it's a 32-bit value, more likely it's a 32-bit CRC.

Yes, which one are you taking about?  Game statstring or message 0x3C?  I'm assuming the game statstring one. I'm not sure where it comes from (never cared), but it definately does not come from any SHA hash, and I don't think there's any CRC code anywhere...  I could be wrong on that last part, though

I'm talking about piece 7 in the Game Statstring for STAR/SEXP games.  I'll get a log of the game statstring.


[edit]
This is it, I didn't see any others with a game statstring in it.  It's 0x09, maybe that should be posted in the game statstring page somewhere?

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

------------------------------------

If I remember I also pointed out that somone thought it was the checksum to the map being used, but I found it never changed and asume its something else that is local to the user.

the diagram warz posted is what me and moonshine put together during 1.09 or 08? so it may have changed.
