Cheat Engine

I'm learning about memory and modifying it etc, so I thought it would be a good idea to do something simple: Monitoring a player's health in Runescape and whenever it goes below a threshold, click food. Nothing big.

I've managed to be able to find a pointer which leads to the health variable and it works fine inside cheat engine, I can see it move up and down as the health does and modifying it modifies the health. However, I can't work out how to get the offset for it even after hours of searching.

Anyway, I've scanned for the variable and found it. Two instructions were found:

mov[edx+ebx*4+0C],eax
mov ecx,[ebx+ecx*4+0c]

How do you work out an offset from this? I tried subbing in the values I received after double clicking on each and had no success.

I then scanned for a pointer and got one working, here is information about it should that be useful:

Ok, thanks. I didn't realize that java was not possible to get a static address for... I've decompiled the client before but they have strong obfuscation accross multiple clients, when a client connects a random version of the client is sent over which makes it harder to get rid of the obfuscation :/

pointers work in java game, assuming the process only has one java game, and everyone used the same jvm version. It's just that the pointer paths tend to be a lot longer in java games

alternatively, you could play with openjdk
