Hi ya!

To learn a bit about Cheat Engine and assembly, I am trying to make a trainer for a game.

Now I stumbled on a problem.
In this game there is a player (me, obviously) and the AI. The units in the game need to eat and have a "hunger bar".

It was easy finding the addresses (screenshot 1).

Now if I check what wrote the "Player health" address it showed me "sub dword ptr [esi+1C],01", now this makes sense.

When I open the Auto Assembler and add the "Cheat Table framework code" and the "Code injection" template, I comment the subtraction away and add it to my table.

When I activate it, it works fine. However the AI's units also do not get hungry anymore (the bastards).

When I dissect the data I find similarities though. (Screenshot 2)

As you can see the 0008 goes from 0 to 1 and 2. Now I might be wrong but I guess that this is the player or AI number.

How can I implement this in my code injection that it only affects my units.

Thanks in advance,

IMT

Hi

If you try to beat CE tutorial step 9 you will learn how to do it Very Happy There are many ways to achieve this:

- Stackview info
- struct dissect
- registers compare

First try to beat step 9, if you continue with problems I will help you more deeper.

EDIT: Your 2nd screenshot is a bad dissection point, you must dissect ESI, not ESI+1C

EDIT2: Use groups in dissection tool, CE will tell you (using colors) which offset is used to difference the player or IA

Thanks for the reply.

I did the tutorial (needed YouTube though) but now I get it.
Already found it, thanks for helping.

And for dissecting I used "0B19737C", "0B197404" and "0B19748C".

Anyway thanks for helping me out.

Just a tip:

0B19737C is the address of player health, you showed [ESI+1C]. This means:

ESI = B197360 = Player Base Structure
+1C is the offset pointing to Health
+24 is the offset that determine player or IA

Then just add this:

Code:
label(enemy)
cmp [esi+24],0
jne enemy
//here, [esi+1C] will point at player's health
mov [esi+1C],A //set player's healt  = 10
jmp return
enemy:
//here, [esi+10] will point to a enemy health
mov [esi+1C],0 //set enemy's healt  = 0
jmp return


It's better to use the base pointer (ESI) in the structure dissect rather than ESI+OFFSET. You used ESI+1C, imagine that the offset to determine player or IA is located at ESI+2... doing this you will never find that offset on the tool

Smile

anyway; Congrats Very Happy

But how do I know what ESI is? Because I searched for the value of health and got that address.

Edit: Already found it. Embarassed
