I have been working on a trainer in the last week or so in my spare time and I have run into a problem. I can not figure out how to separate the player's health from the enemy AI's health. From what I have read I am supposed to get the player's health address and store it in a variable, and then check when health changes to see if it is that address or not. The problem is, I have no idea how to do that and any posts I have found on the subject have been somewhat confusing to me.

Here are the scripts I am working with (have removed the game name as I am fairly certain I'm not supposed to mention that):

Yeah. you're basically just nopping the instruction and the one behind it

I assume that the access to [esi+0C] is the access to the health?

If so, go to that instruction in the disassembler and rightclick it. then choose "find out what addresses this code writes to"

Get hit first so you know your own health address and then hurt one or more enemies (DO NOT KILL THEM)

Now go to data dissect fill in your players healthaddress-0c and create a new structure.
Now add a new address and fill in the address of the enemy/enemies

Now see if you can find out how to distinguish between you and the enemy.

Perhaps a certain byte is always 0 for you and 1 for the enemy. Or there is a pointer somewhere that points to your name, or see if there is some other pointer you could make use of

Also, if you use find what accesses your health you might get a function that is called ONLY for your player (to render the health)
You can do a hook there and then check in the routines that cause damage if the health address is yours or not and if not, skip

Thanks for the reply.

So I have looked at the structures you said to create and I want to test for a value now to see if it is correct.

I have found that offset 001C a 1 for the enemy and 0 for the player. How do I check this? I am guessing it is something like:

You could always run the game in a window and debug it, but yeah, small scripts like these are usually believing that the code works and try it

As for your code it might work, but i find your use of jmp returnhete a bit like working with a sledgehammer, i think you just nopped that code without knowing what it does

Also, another spot to check is the first 2 bytes of a structure, sometimes the player has a unique value there

There is a function that calls every tick and it is checking to see if health should be increased and or increasing the health. How can I retrieve the address from that and use it in another script? I tried using a symbol to store but I think maybe I don't quite understand them very well yet as it doesn't seem to work.

This is called every tick (or close to it):

Ok I'm trying to access the symbol from another script but I'm not sure why it doesn't work. It says it can't compile the code.

I was trying:

You can not use 2 address specifiers in the same instruction, and you're comparing the value of health to the address of health

Do:
