thanks for the tip

i'll work in a solution

hmmm, ok
but I guess the others random maps I can't generate right? they are all generated by this seed?
like cold plains in act1..

Is there any way to know what map my char is when I logon?
I mean, imagine if I'm in act1, there are 3 possible maps, how is determinated which map you're supposed to draw? Is this send by any packet?

Thanks for the help, Now I know what's the problem. I'll try to fix

Yeah, you are right, there was a mistake when I receive the packets... Apparently I received 4 compressed packets in 1 packet.
So, I would have a 1400+ lengh packet and I treated it as only 1 packet, and forgot the rest.
I'm fixing it now, thanks

Yeah, I'm noticing that. The last 0x00 bytes are nothing. this is just because my "logger" writes a whole line. If the packet ended before the line. It writes 0x00.

I've implemented a better logger now:

First packet: OK!

I don't have that packets before decompressed :/

I'm using this decompressor code: http://forum.valhallalegends.com/index.php?topic=15601.msg157328#msg157328

This code is reliable? Do you have any others decompressor codes?
I'm using c# but I know others languages, if you have another code. In c++ would be good, so I could build a .dll to use in my C# program

yeah, I'm logging the whole packet before it's parsed, then I log what my parser class did, and I check the whole packet that was logged to see if it's right

Here's the packet where I extracted de 0x0D packets:

0D 05 00 01 06 00 0F 13 00 00 0D 00 2E 00 00 5A
11 43 12 80 AC 03 00 00 00 98 00 73 11 44 12 80
10 11 08 00 AA 01 03 00 00 00 0C 69 59 F9 FF 1F
6D 03 00 00 00 73 11 44 12 80 51 02 06 00 00 00
4E 00 6B 11 23 12 00 00 51 02 05 00 00 00 25 00
79 11 43 12 02 00 51 02 04 00 00 00 23 00 6C 11
40 12 00 00 51 02 03 00 00 00 27 00 7D 11 22 12
00 00

Here's what I done

0D 05 00 01 06 00 0F 13 00 00
0D 00 2E 00 00 5A 11 43 12 80

AC 03 00 00 00 98 00 73 11 44 12 80 10 11 08 00

AA 01 03 00 00 00 0C 69 59 F9 FF 1F

6D 03 00 00 00 73 11 44 12 80

51 02 06 00 00 00 4E 00 6B 11 23 12 00 00
51 02 05 00 00 00 25 00 79 11 43 12 02 00
51 02 04 00 00 00 23 00 6C 11 40 12 00 00
51 02 03 00 00 00 27 00 7D 11 22 12 00 00

This is right?


Here's the whole packet that i got the 0x51:
51 00 00 28 00 00 59 F9 FF 1F 6D 06 00 00 00 5A
11 43 12 80 AC 03 00 00 00 98 00 73 11 44 12 80
10 11 08 00 AA 01 03 00 00 00 0C 69 59 F9 FF 1F
6D 03 00 00 00 73 11 44 12 80 51 02 06 00 00 00
4E 00 6B 11 23 12 00 00 51 02 05 00 00 00 25 00
79 11 43 12 02 00 51 02 04 00 00 00 23 00 6C 11
40 12 00 00 51 02 03 00 00 00 27 00 7D 11 22 12
00 00 07 80 03 A0 03 01 51 02 02 00 00 00 81 01
84 11 21 12 00 00 AC 02 00 00 00 09 01 80 11 25
12 80 0E 01 AA 01 02 00 00 00 0C 69 59 F9 FF 1F

I splitted like this:

51 00 00 28 00 00 59 F9 FF 1F

6D 06 00 00 00 5A 11 43 12 80
AC 03 00 00 00 98 00 73 11 44 12 80 10 11 08 00
AA 01 03 00 00 00 0C 69 59 F9 FF 1F
6D 03 00 00 00 73 11 44 12 80

51 02 06 00 00 00 4E 00 6B 11 23 12 00 00
51 02 05 00 00 00 25 00 79 11 43 12 02 00
51 02 04 00 00 00 23 00 6C 1140 12 00 00
51 02 03 00 00 00 27 00 7D 11 22 12 00 00

07 80 03 A0 03 01

51 02 02 00 00 00 81 01 84 11 21 12 00 00

AC 02 00 00 00 09 01 80 11 25 12 80 0E 01

AA 01 02 00 00 00 0C 69 59 F9 FF 1F
For me, everything's appear to be right, but that initial 0x51 packet doesn't make sense to me, I mean, there are others 0x51 packets and they are not that way

Well, I got this packets 0D:

0D 05 00 01 06 00 0F 13 00 00
0D 00 2E 00 00 5A 11 43 12 80


But the documentation for this packet is:
0x0D
D2GS_PLAYERSTOP
Lengh = 13

0D 00 XX XX XX XX 07 67 16 D8 15 00 5D
(BYTE) Object Type
(DWORD) Object ID
(BYTE) Unknown (very's from 0 to 15)
(WORD) Location X
(WORD) Location Y
(BYTE) Unknown
(BYTE) Life%

Well, I think this packet changed, do you know what are the possible information in this packet now?
I captured this 2 packets while standing in the same position, that's weird because I can't see the location WORDS, their values difference have to be small, right?

now I got this packet 0x51

51 00 00 28 00 00 59 F9 FF 1F

Previously documentation:
51 02 XX XX XX XX 25 00 59 16 A0 15 02 00
(BYTE) Object Type
(DWORD) Object ID
(WORD) Object Unique Code
(WORD) Location X
(WORD) Location Y
(BYTE) Objects State (0x00=no &HE will follow, 0x02=expect a &HE)
(BYTE) Interaction Conditions


Well, in both cases, shouldn't the IDs have lower values?

omg, you're good at this more efficient than my packet splitter class... lol

I'm gonna try to find out something about this "unknow" packets, but how do you know how to separate the packet? just intuitive? any hint for a beginner?

You really helped me, thanks 

Thanks I found the lenghs, its for the 1.10, but it helps

I didn't see anything about this packets, and this values 00 01 are very weird for me.

I'm almost sure there's something wrong, I don't understand this lot of 00 bytes in the packet

Well, I make my bot enter the game and now I'm trying to read the packets I receive, but I'm having a little problem.

This is the part of a packet I decompressed, and now I'm trying to read it, but I found some problems
8F 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 59 18 00 00 00 05 42 69 67 4D 61 63 00 00 00
00 00 00 00 00 00 00 00 00 00 00 AA 00 18 00 00
00 0C 69 59 F9 FF 1F 76 00 18 00 00 00 94 08 18
00 00 00 00 00 01 02 00 01 01 00 01 D9 00 01 DA
00 01 DB 00 01 DC 00 01 03 00 01 22 00 00 18 00
00 00 DB 00 01 CB 00 22 00 00 18 00 00 00 D9 00
01 CB 00 5E 01 00 00 00 00 00 00 01 00 01 00 00
00 00 01 01 01 01 00 01 00 00 00 00 01 00 00 00
01 01 00 00 00 00 00 00 77 28 06 00 00 00 00 00

The first packet is ping response, that's OK.
8F 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00

The second packet is D2GS_PLAYERASIGN
59 18 00 00 00 05 42 69 67 4D 61 63 00 00 00
00 00 00 00 00 00 00 00 00 00 00
In this packet I'm seeing my self, so:
My player ID: 18 00 00 00
I'm a druid, so: 05
And my name: 42 69 67 4D 61 63
Well, here I didn't understand why my location is 00 00 00 00
But that's not the problem, let's move on.

Third packet:
AA 00 18 00 00
00 0C 69 59 F9 FF 1F 76 00 18 00 00 00
Well, this is packet D2GS_COMINFOADD, its lengh is determinated by its 7th byte
soh the packet lengh is 0C (12)... Ok, next packet:

Fourth packet:
94 08 18
00 00 00 00 00 01 02 00 01 01 00 01 D9 00 01 DA
00 01 DB 00 01 DC 00 01 03 00 01
This is packet D2GS_SKILLSLOG, its lengh is 6 + (byte1 * 3).
In this case the lengh is 30, right?

Fifth packet?
And now, the next packet ID is a 0x22, I don't what packet it is, I found nothing about it, so i'm almost sure I'm doing something wrong, that's why I posted everything I did here.
You guys have any idea what I'm doing wrong?

Thanks in advance

hehehe, ok, i thought your minimap was draw based on .ds1 files
I prefere building the minimap using the map files. But I need some documentation about it, if I get anything I'll share here.

Thanks, I understand now.

I was thinking the locations were relative to the map. Like, if my char was standing on map townE1.ds1 in location (150,50) of the map, the X and Y location would be that. I was thinking like in other games where the maps aren't together like Diablo.


You wrote the code to draw that minimap?
I wrote one, but my map isn't quite right yet, I don't know what is walkable and what is not, I just read the walls layer and put them as unwalkable. but this isn't right because I'm seting a whole cell as unwalkable, and a wall cell can have walkable subcells.
Do you know how to calculate exactly what is walkable and what is not?
If you knew what the 4 bytes in each cell mean, it would hep me a lot.

Yeah, but I'm trying to understand how the client make this packets

I logged the packets send by my char while I was walking around town

0000  03 46 12 C9 11                   
0000  03 42 12 C8 11                               
0000  03 3F 12 C4 11                                 
0000  03 3E 12 BC 11                                 
0000  03 3B 12 B8 11                                 
0000  03 38 12 B5 11                                 
0000  03 34 12 B4 11                                 
0000  03 32 12 B2 11                                 
0000  03 2D 12 B1 11                                 
0000  03 29 12 B3 11                                 
0000  03 28 12 B8 11

So, in the first packet my location X would be 46 12, and Y = C9 11
But these are high numbers, so the way I'm thinking isn't right

Why the second byte in locations always repeat?
I walked around all the map and the bytes 12 and 11 didn't change

The location are calculated this way right?
(0,0) ------------------------> X
|
|
|
\/   Y

Because is like that the map is read from the .ds1 file, if not, I'm being really dumb!   

Hello, I've been reading this foruns for a couple weeks now, and I started to code a "bot" in fact I just make a program that connects to Bnet and log into a game.
But now I want my char to move, and I cannot understand the 0x03 packet, I mean:

03 65 15 61 12
(WORD) X location
(WORD) Y location

How this X location and Y location are calculated?

For example, the town map in act one has:
57 cells - Width
41 cells - Height

This mean, in coordinates:
285 subcells - X
205 subcells - Y

How can i convert this X, Y based on the subcells, to the X, Y I have to send in the packet?
I need this because I draw like a minimap on the screen, and I want the char to go the location I click.
Anyone knows how to do that?

Thanks
