I didn't look through it all, but pretty nice.  Good work.

[Hero]

this is exactly what i've been needing, thanks

[PaiD]

Same, I needed this alot. Thanks Man!

[maldn]

i have some comments on the gameInfo packet.
about the encoded part.
i am very certain, as i stated in the other thread, that the encoded part starts after the 0x00 after the gamename. why?
1) in replays it starts there
2) some values tagged unknown by you do vanish...

example:

Code Select Expand


i let my encoded data start with 01034907... not with 997d01...

static const char enc1_raw[] =
{
0x01,0x03,0x49,0x07,0x01,0x01,0x7d,0x01,
0x99,0x7d,0x01,0xa3,0xdf,0x1d,0x43,0x4d,0x8b,0x61,
0x71,0x73,0x5d,0x29,0x35,0x29,0xcd,0x4d,0x6f,0x73,
0x75,0x55,0x65,0x6d,0xe9,0x71,0x6d,0x65,0x2f,0x77,

0x03,0x73,0x75,0x01,0x01
};


if we decode that, we get

we are interested in the first 13 bytes. after that comes gamename&creator name and a null-char/byte.
lets have a closer look (for reference look at w3g_format.txt section 4.3/4.4):

decoded gamesettings:
02 48 06 00 00 7c 00 7c 00 a3 df 1c 42

02 -> 00000010 -> fast gamespeed
48 -> 01001000 -> !hide ; !explored ; !nofog ; default ; no obs ; teams together
06 -> 00000110 -> fixed teams: on
00 -> 00000000 -> no full shared control; no rnd hero; no all rnd; no obs/refs
00 -> 00000000 -> 0
7c -> 01111100 -> unknown (0 in ladder games, but not in custom)
00 -> 00000000 -> 0
7c -> 01111100 -> unknown (0 in ladder games, but not in custom)
00 -> 00000000 -> 0
a3 df 1c 42    -> map checksum


looks good eh?
you dont have your obscure 'codedTag' and the unknown 0x7c00 anymore.

p.s. for those of you lazy looking into w3g_format.txt, here is section 4.4

Make sure you have decoded the GameSettings (see 4.3).

The game settings (extended options on create game screen) are packed using
various flags distributed over 13 bytes.
For details about the single options read the file
"support/Readme/(PC)UIMainMenus.html"
in your WarCraft III installation directory.

Denoted below are only nonzero flags.

offset | bitnr | Description
-------+-------+---------------------------------------------------------------
0x0000 |  0,1  | Game Speed: 0 = slow, 1 = normal, 2 = fast, 3 = unused
-------+-------+---------------------------------------------------------------
0x0001 |   0   | Visibility: 'hide terrain'
       |   1   | Visibility: 'map explored'
       |   2   | Visibility: 'always visible' (no fog of war)
       |   3   | Visibility: 'default'
       |  4,5  | Observer  : 0 = off or 'Referees' (see 0x0003 Bit6)
       |       |             1 = unused
       |       |             2 = 'Obs on Defeat'
       |       |             3 = on or 'Referees'

Does anyone know how the game signature is generated?

[DotA.For.Rest]

Can u post it here? plz.
i have W3G_FORMAT version 1.12
and W3G_ACTIONS version 0.97
if you have new version post actions too, i cant found them

also i've update W3GS_GAMEINFO (look first post again in this topic)

[maldn]

the game signature isnt exactly generated.
if you have had a lookk at the actual bytes you might have noticed that 0x50583357 is PX3W in ASCII.
taking byte-order into acount and you end up with W3XP -> Warcraft 3 Expansion (TFT)

as for the w3g_* files, have a look at the cvs at http://warcraft.kliegman.com/

and a minor note: i wouldn call is 'game creation counter' its more like a game-id thats more or less upcounting on new seen/created games.
but you can use whatever you want like 0xdeadbeef or so...

Updated! Added SID_GETADVLISTEX and SID_STARTADVEX3 for WAR3/W3XP games, and changed some names of fields.

thanks for link, got new versions of this files

Ah ok.  So it's the Product ID then.  Errr now I see, the guy documents the "Packet ID" as "Packet Signature".

I guess I'm just used to how BnetDocs documents packets.

It seems they use "ID" in place of "Signature".  I guess I inadvertantly associate the word "Signature" with some unique value sometimes.

Great work.  I wish my Uni port forwarded port 6112 so that I could try and write a "DL Only" bot this summer while I'm bored as hell working there.

when im  start learning english by my profession, i should understand that there is 2 different english languages, one is Speaking English, and other is Technical English. Cuz im programmer i decide learn Technical, and now i have alot of problems with speacking english ).
i telling its for explain why Data Markers means same as Data Tag, why Object ID means Signature. its same for translate but first in Speaking English, second in Technical. i have read alot of Tech Books, but none of simple. Thats how i understand all of this.

Im naming objects like it do most of Tech Books. Ofc i can name them with any names, but this more readable.
for Tech books ID used only for internal object/structures/other numerations only. Thats why Player ID/Slot ID.

Download Only BOT Cool Idea, did not thought about it. Great.

I tried to sniff 0xf735 and 0xf736 packets,
but apparently I can't get them when I create a private game on bnet.

I see these packets when someone else hosts, but not when I do...
I can see the other packets, so it's not a filter problem.
I am wondering if there could be some warcraft III FT version that does not emmit those?

Another question, are any information available about the various chat message packet ?

i am very certain, as i stated in the other thread, that the encoded part starts after the 0x00 after the gamename. why?

The 0x00 after the game name is called a null terminator. It's actually part of the game name, telling the computer where the string of bytes that identifies the name ends at.
