A little help about ASM

Hi, im trying to learn a little bit of ASM, so i think you guys can help me a little bit:I saw a lots of times someone saying "search for the funcion ZPostChannelChat", "search for ZCharacterManager::GetCharacterIndex", but how can i find them? I mean, how can i search for functions at ASM code? Thanks!

Download the Gunz PBP dump. I've posted it here a couple of times. Also GunzOld.exe and test.txt.txt combination will also help you.

Ok, im going to take a look at them. Thanks T6!

EDIT: Btw i searched for Gunz PBP dump and it doenst found nothing about it. I think is cuz PBP is a small word and the searh dont use it... Also searched at google and fonud nothing.

here is the PBD ^^ i dont remember who uploaded this....Hmmm well the credits go to him :p

GunzOld.txt and test.txt.txt will be of more help for finding the functions inside gunz. To know the parameters you'll need the dumps.

GunzOld + test.txt

also, to call Classes functions you first need to get the class instance (unless these functions are static) and move the instance to ECX register, for example.

CALL ZGameClient::GetInstance
MOV ECX, EAX
CALL ZGameClient::SomeFunction

this method only works if the class has the __thiscall calling convention, (the 99% of classes functions are __thiscall ), if for example, the function has the __cdecl calling conversion you must pass the instance as parameter.

PUSH Parameter1
PUSH Parameter2
PUSH Instance
CALL Someclass::Somefunction

Yay, this helped me alot! Thanks
