Now i want to read it in c# :

Code:

if ((current.Opcode == 0x3015))
                            {
                                    current.ReadUInt32();
                                    current.ReadUInt8();
                                    current.ReadUInt8();
                                    current.ReadUInt8();
                                    current.ReadUInt8();
                                    current.ReadUInt8();
                                    current.ReadUInt8();

                            }

But after first ReadAscii i have error (can't read when packet ends).

What am i doing wrong?

Each character near you have different number of items, active buffs and so on. So first you need to parse that before you can get UniqueID.

hmm. maybe is there other way to get player ID and Nick ?

Nope.

04/19/2014 19:33 lewy1000#5

Maybe can you tell me how to do this?

04/19/2014 20:09 DaxterSoul#6

Search for source code from bot projects (zBot)
Maybe you'll get an idea how it works...

04/19/2014 20:21 lewy1000#7

Ohh thx! :)

04/19/2014 21:48 zeteris#8

Yeah you can check source codes I've released

[Only registered and activated users can see links. Click Here To Register...]

I don't know if links are still alive. These sources were very buggy ( I used wrong method for parsing everything, but it should help you).

GL on what you're doing :)

i check your source code but still can't finde how to get players CharName from packet
o.O
Uhh... maybe sample or some help?

Use this if it helps, most complete parsing of the player spawn packet around.

Code:

    [dword] pk2 (char)
     [byte] volume_height
     [byte] flag (quest_rank)
     [byte] flag (icon)

How so? It's only missing 5 bytes (which I rarely saw ever change) and it takes into accounts other variables such as riding transport, stalls and un-equip timer. Find me a more complete one.

Edit:

Code:

if(buff) {
    [dword] pk2 (skill/item)
    [dword] Duration (ms)
}

--> Add:
            foreach(ActiveBuff)

                RefSkillID
                Duration

                    1   byte    Creator
                }
            }

I'm not trying to offend you, just corrections. I might have some mistakes as well :D
Thanks for guild_war and pk_status, i'll check them.
You are doing great job at least if you're parsing them yourself and not collecting them together :P
