hi there, i normally make codes for the games myself, but there's this one game that has a really tricky address, the knives address in the game mentioned above. I found the address of the knives value, 100% authentic, but the problem is, when i tried to increase the value, for example, the original amount of knives i have is 5, to an amount of 10, after i used finish the 5 i initially had, when i try to use till the 6th, it will crash the game immediately. Anyone has any ideas how to solve this problem? Help appreciated.

You can read here http://forum.cheatengine.org/viewtopic.php?p=5216239#5216239. That was a long battle.
First infinite knives codes were simple. But buggy (disappearing sword, etc). Then I fixed this with "mov al,5 ". Still, there were bugs. Then I made huge script, it was slow, but working.

Then I made this (cons? no more Very Happy

does your script work against the check that was used in the game? it's sort of like comparing the knives value against some other address, if the game calculates that your knives value has already reached zero, but you changed the value via cheat engine, it will immediately crash when u try to use the extra knives that you have just given yourself...

This game is not using live.

i realised something, the address that i hooked to is the opcode writing the address, while there's another opcode that is accessing the address, and the crash is caused by the accessing address. now if i use the accessing address to change the value instead, it is all good... Very Happy

thanks for all your help!

Could you paste AA script?

i overwrote it with another game's cheat table -_- but nevermind i will try to reproduce it. but first of all, can you tell me how to make it non-full screen? by using 3d ripper, it crashes so often.

hmm that method crashes alot for me... when i try to use toggle breakpoint, after it breaks and i got the value i want, i removed the breakpoint and closed the viewer, when i go back to the game, either the camera gets stuck, or the whole game gets stuck.

EDIT:
ok after a lot of trouble i managed to come up with a script that's almost bugless... do help me test if there's any bugs with it Very Happy

You are sure about this thing?

esp thing:
if the hook is done at a spot with no stackframe setup yet (so no pushes) this routine can be used to find out if the function was called from a specific address (or else if it contains the pushed address of a function table it's useful as well)
And word would be used to deal with the exe/dll address randomization

Nevermind. He has different AC:B version. For me, it would be
"cmp word ptr [esp],6639"

"cmp ecx,esi and je" isn't necessary (no difference if you use this or not)

But this "movzx eax,byte ptr [ecx+02]" sets 76 knives for me, for him 19. This would be better: "xor eax,eax; mov al,5" (or "mov eax,5").
