Do I have to find out what accesses few adresses to do damage hack?

[ulysse31]

It's a start that makes sense.
It's probably gonna be a what's write to this adress instead of access, but access give you same and more information so that works as well.
If it's damage hack then you probably want to increase your damage.

You can either find ennemy health value with scans and see what writes it.
You can scan damage numbers (although 99% of the time it's bad idea and harder because they dont share the same location)

Can also scan for your character stat and edit these.

Say you found what write to ennemy health, now you do a code injection.

Finding enemy health looks a bit difficult. Characters stats looks easier. I have an address for my characters animal. Can I edit my damage by finding what writes/accesses to this address?

You can find out what instructions access your health while idling.
Then go through those and find out what addresses those instructions access.
Often times, several instructions will be querying enemy health too.
So this is an easy way to find the target's health immediately.
From there, you need to find out what instructions access their health but NOT yours.
You can then set their health to 1, or 0 for a kill all script.

Oh okay! Thanks for the help.

If it's one of those games that display the number of HP subtracted when hit, then you can easily make a damage hack with that. By searching the number subtracted each hit you should be able to narrow it down pretty quick.

Another way of doing it is like what the other 2 suggested. Finding the routine where health is subtracted and setting the enemies HP to 0 when hit. Like an insta-kill. If you want, post some of the code you found, and we can maybe help you a little more.
