Hi all. I'm new on forum :) I want to develope some Game plugins for game LINEAGE 2. But I dont know how to start. How can I use game's DLLs? For start I just want to make simple app, with 1 textitem and button. on-button-click event will get player current location coordinates in game. Some similar plugin (with more features) is on that page: http://www.l2agent.de but without any source. Thanks for your help.

Hello.

I think if you want to start game-hacking, the most important part is to learn x86 intel assembly and techniques of reverse engineering.

Basically, the idea of gamehacking is to find functions the game uses to accomplish certain tasks - and integrate those functions in your own code. I guess you knew that.

Look into Dll Injection.

simple answer about dll injection:
Dll injection itself is you are making your own dll and force that into the game process.

well gl.

Theres a couple tools you can use to help you find memory address within another program. Theres the well known TSearch but its kinda dated. Then theres CheatEngine http://www.cheatengine.tk

Refer to their forum for its usage.

Some games use detection mechanisms to see if they've been injected to so DLL injection doesn't always function.

You could do a hook/callback to winsock and parse the raw data. However this would require you know the structures of the packets.

If you do the memory address approach, refer to ReadProcessMemory and WriteProcessMemory of the Win32API.
