[D2GS] 0x22 Packet??? (S>C)

[lokis]

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

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

The second packet is D2GS_PLAYERASIGN

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

Aside, if your useing that d2gs research topic as referance, some packets arnt listed.
I think somone posted the packet lenghs on this forum somwhere, try search D2GS packet lenghs -- but they were for 1.10.
Also, its not 00 01, i posted format with out the packet id:

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'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?

Yeah intuitive and past exp, I researched the whole protocol with out knowing any of the packet lenghs, packet values or anything. D2GS Rersearch thread was a result of a few weeks after, I later continued and figgerd out almost everything via packet logs.
Player ID's were my main target, when i was trying to figger out what was what.
I have all the packet formats on my computer *somwhere*, most are in the back of my head somwhere.
Alot of the codes/values/bit fields can be found in the txt files in the mpqs (like monstats.txt etc)
I have been meaning to create a new D2GS packet thread, but just never got round to it.
Any packets your not sure about, post them and i can give a basic discription of there meanings.

[lokis]

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

Previously documentation:

(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?

Well, I got this packets 0D:

Looks like somwhere before you got them, you parsed a packet with the wrong lengh.
Remember those packet lenghs are for 1.10, a few packets changed slightly in 1.11 (not many tho)
You need to print out each message as you recv them, and back track when it brakes, to find out what message was passed with the wrong lengh, then change it to the 1.11 lengh.
When a packet gets parsed with the wrong lengh, some bits of broken data will fall into some parsers, so its a good idea to habve plenty of error checks -- always good for new patchs and detecting changes/brakes.
If you want, post the parsed messages and i can point out what and where it went wrong if you like.

That one looks like it was some location based packet -- not sure what one tho, but im seeing an X/Y location as well as NPC life percent there.

Aside, got some better documentation here for 0x0D:

(BYTE) Life Percent (Mainly for NPC's only, normaly 0 for players)
(BITS[4]) Melee/Missle sound/animation FX
(BITS[4]) Damage type sound/animation FX


Valid/Known States for a player (entity 0):
    0x06 = get hit
    0x07 = stop
    0x08 = Die (No esc)
    0x09 = Dead (Esc, corpse is replaced with dummy)
    0x12 = Nothing?
    0x13 = get hit (no animation)
    0x14 = get hit
    0x15 = Heading Change (Changes direction your character is facing)
    0x16 = nothing?
    0x17 = nothing?
    0x19 = Dodge

Valid/Known States for a NPC (entity 1):
    0x00 = Nothing (X/Y Must be 0)
    0x01 = Walks To X/Y
    0x02 = Stops walking (X/Y N/A)
    0x03 = Stops walking (X/Y N/A)
    0x04 = ???? (NPC went invisible)
    0x05 = ???? (NPC went invisible, X/Y Must be 0)
    0x06 = Takes Hit (animations useable, X/Y N/A)
    0x07 = Walks To X/Y (And auto stops)
    0x08 = Dieing (animations useable, X/Y N/A)
    0x09 = Dead (X/Y N/A)
    0x0A = Attack (X/Y Must be 0)
    0x0B = Attack At location X/Y
    0x0C = Resurrect (X/Y N/A)

    0x0E = ???? (NPC went invisible)
    0x0F = ???? (NPC went invisible, X/Y Must be 0)
    0x11 = Cast At Location X/Y
    0x12 = Dodge attack (X/Y Must be 0)
    0x13 = Get hit with no effect (X is the animation byte)
    -> higher states are just strange and effect the layout of the packet body


Missile/Melee codes:
    0x00 = Normal
    0x01 = Stab1
    0x02 = Stab2
    0x03 = Stab3
    0x04 = Stab4
    0x05 = Stab5
    0x06 = Stab6
    0x07 = Stab7
    0x08 = Wooden1 (like from staffs etc)
    0x08 = Wooden2
    0x0A = Arrow1
    0x0B = Arrow2
    0x0C = Arrow3
    0x0D = Normal?
    0x0E = Normal?
    0x0F = Normal?

Damage types:
    0x01 = Magic sound/graphic
    0x02 = Fire sound/graphic
    0x03 = Cold sound/graphic
    0x04 = Lightning sound/graphic
    0x05 = Posion sound/graphic
    0x06 = Wobble sound/graphic?
    0x07 = Knock back sound/graphic
    0x08 = Stun sound/graphic?
    0x09 = Redemtion sound/graphic?


The states and effect bitfields are the same for 0x0C, 0x69 etc

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:

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

[Ringo]

Can you post the whole logon dumps, like that?
I need to see the block of data before those blocks, to see what went wrong.
It looks like its a bad packet lengh, but it might be bad compressed message declumping.
You just posted the after math, i need to see the before and after =)
Somthings braking tho, no doubt of that.

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

[Ringo]

Looks good, but its braking at the end:

Those 3 0x00 bytes at the end will cause big problems, its probly due to sending 1 byte to many through the decompressor, or somthing of that nature.
I persioanly use this code, which is where most ports orginate from i would guess.
http://forum.valhallalegends.com/index.php?topic=585.0
I would take a guess that your problem is with the compressed header (when its 2 bytes)
If the next clump is abit messed up, it would point to bad parseing of that header, leading to the next clump to be badly offseted and some of the header going into the decompressor and twisting the data.

[lokis]

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!

Here it tryes to read a packet 0x2E, that doesn't exist


[Kp edit: killed long lines that broke the table layout.  Learn to use line breaks in your hex dumps.]

[Ringo]

Looks like your 2nd compressed packet isnt all there.
I take it your not buffering any broken TCP packets?
When you recv compressed data, call GamePacketSize(), if the lengh of the data is under returned lengh + returned offset then wait for more data
other wise you have all the compressed message and can decompress it.
And just keep on doing that, making sure all the data is there before decompressing -- other wise you will start "as new" in the middle of a compressed packet, which was causeing the twisted data:

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
