Hello!

I'm new here but I'm using this forum just to read some tutorials.

I'm trying to learn about making some basics cheats to some games and I found that I could start doing in the Nation Red (steam game) game. I already have done a basic godmode and it works great (thanks for the tutorials here). I've found the base pointer to it and it works even If I restart the game.

What I'm trying to learn is how can I discover the enemy health? Let's say: in this game I dont have a health bar under the enemys and even got a number of the current enemy health. Can someone point me to the right direction?

I was reading another tutorial in here and say that I maybe have to find what access the player health adress. But I'm getting lost...

Thank you guys.

This is what I got working:

One option if you're able to pause the game, find an enemy and search unknown value.
Unpause and shoot him once
Pause and search decreased value
Repeat

This usually works to narrow down the address for that enemy but you might want to debug that address to get all the enemy health addresses.

What you could do is hoping that there is a universal "damage" function that deals damage to you and your opponents. It's at least worth trying. Right click on your health and use "find out what writes to this adress" and loose some health. A list of instructions writing to your health will be displayed (who would have guessed). Open one of those instructions in the disassembler and set a break point on it. If it also breaks when you shoot an enemy and not only if an enemy hits you, you got lucky: then this function also damages your enemys. You can, then, simply use "find out what adresses this instruction accesses" in the disassembler and it will list all the enemy's health's adresses once you shot them.

Tracking this adress to the base pointer, i asume you will find some sort of array (looking something like [eax+ecx*4]) which may be a list of enemys.

As for the array, you may also try looking into the base pointer you have allready found. If there was something like [eax+ecx*4] , its likely that you are also part of this array. You can then simply change the offset of this pointer (e.g increasing it by 4) and will find all the enemys. (In Star Wars Battlefront for example, enemys are safed in this way).

I just found the boss health here. Using your tips, thanks!

Now, I now to what writes to that adress, but really dont know what do to with it.

Here is a screeshot:

EDIT: Corruptor, thank you! This is an amazing tip. I'll take a look right now!
Thanks!
