Ace's 1.10 Complete PacketList
This packet list includes definitions and will (pretty soon btw) include examples.
Credits go to Gayak and the "others" that made the first ever packetlists, and to Thohell for creating d2hackit, which I'm using to create the examples and get some extra info.
This list has the following format:
Index:
- Variable types
- SENT packets
- RECV packets [not yet]
- Definitions
Variable types: What kind of data goes inside the packets?
BYTE = XX (from 00 to ff)
WORD = 2 bytes
DWORD = 4 bytes
*char = Array of bytes each representing a letter
SENT packets: What does each packet do?
Definitions: What does each packet parameter mean?
[WORD x]
2 bytes containing a x coordinate (first byte is usually "zone" and second is coord inside that zone)
[WORD y]
Same than x but with y coordinate
[DWORD entity kind]
[DWORD entity id]
Every entity in the game has its own id, it's like its identification number that makes it different from other entities...
[*char message]
Group of characters containing the message, 1 byte per letter (hex ASCII)
[DWORD item id]
Every item has its own id, it's the same thing that happens with entities
[DWORD xpos]
x position in a buffer starting from 0 (XX 00 00 00) (when putting an item, the coords define the upper-left corner of the item). Inventory goes from x=0 to x=9
[DWORD ypos]
y position in a buffer starting from 0 (YY 00 00 00) (when putting an item, the coords define the upper-left corner of the item). Inventory goes from y=0 to y=3
[DWORD buffer]
00 00 00 00 = Inventory
[WORD body position]
01 00 = Head
02 00 = Amulet
03 00 = Armor
04 00 = Left hand
05 00 = Right hand
06 00 = Left ring
07 00 = Right ring
08 00 = Belt
09 00 = Boots
0a 00 = Gloves
[DWORD belt position]
0c 0d 0e 0f
08 09 0a 0b
04 05 06 07
00 01 02 03 <- Lower line (the one you always see)
[DWORD option]
UNKNOWN
[DWORD NPC tab]
When buying it's always 00 00 00 00, when selling it varies
[DWORD cost]
When sniffing, it will tell you how much buying an item costed (in hex), when sending the packet it's not needed
[DWORD merc id]
As entities and items, mercs also have ids, nothing to say.
[BYTE stat]
00 = Strength
01 = Energy
02 = Dexterity
03 = Vitality
[BYTE skill]
Every skill has its "id", from 00 to FF (note: some assassin skills are out of that range, being [XX 01], when this happens, XX will go in the [BYTE skill] place, and the 01 will add to the next byte. I know this is not clear enough but I'll explain in next "releases" or edits of this post.
[WORD soundmessage]
19 00 = Help [0]
1a 00 = Follow me [1]
1b 00 = This is yours [2]
1c 00 = Thanks [3]
1d 00 = Sorry [4]
1e 00 = Bye [5]
1f 00 = DIE! [6]
20 00 = Run [7]
This PacketList was made by TheAce, you can copy it and post it anywhere else as long as you state that I did it. If you edit it, you still have to say that the original was made by me.
CM, if you are around, sticky this or something, but leave it editable because I'll be adding stuff everyday. I hope the PacketList helps people who want to start with hacking but don't know where to start.
