hi,

i try to make a trainer for my own. the game is: Thief: The Dark Project.

i have read many other tutorials, in other games works it fine but this time...


1. i search the value and find out what access this adress
2. i change the value
3. i get these infos:

004BD56F - 8B 44 24 28 - mov eax,[esp+28]
004BD573 - 83 C0 0C - add eax,0C
004BD576 - 8B 54 F9 04 - mov edx,[ecx+edi*8+04] <<
004BD57A - 8B 08 - mov ecx,[eax]
004BD57C - 89 54 24 10 - mov [esp+10],edx

EAX=02714850
EBX=00000053
ECX=02724E7C
EDX=0000001C
ESI=0271485C
EDI=0000004A
ESP=000CF704
EBP=00000000
EIP=004BD57A


4. click on 004BD576 - 8B 54 F9 04 - mov edx,[ecx+edi*8+04] << and more info
5. search for hex value ECX=02724E7C and find the adress 02714874
6. add adress manually, click pointer and fill in the adress.

Pretty easy actually, the offset is EDI*8+04.

Edi is 4A so do the math.

I don't think this game has only 1 level pointer though and it will change upon game restart. You might need to dig deep and get a 3 or 4 level pointers to get the base pointer.

I don't recall exactly but i think it was thief deadly shadows or this game that sunbeam did a really awesome series of tuts on, you might wanna search for that to get the better understanding of the game engine.
