i guess there are UDFs (includeable Scripts, like NomadMemory.au3) for doing this

try to find some by using google...
I think these UDFs will call a function from a .dll, so you might get "Cheat Engine" and simply call the function on your own if you are not able to find a Script...
Besides you could try to find the so called "Pointer", it's Addresse will nerver change, you could find a Tutorial right
