Cheat Engine

[gdCheater]

I've been making some simple hacks for Grim Dawn using Cheat Engine, C++ and AutoHotkey.
So far I managed to do game speed toggle / freeze experience and few others.

I'm a novice at this and not a very good programmer. I've been using mostly Referenced functions
but now I need to get to a function Game.GAME::Item::CanAutoPickup that's not there,
only in Enumerate DLL's and Symbols. See the screenshot below.
Also functions on the right seem to share the same incorrect address where something else resides.

Would you be so kind to give me some tips what to try further or maybe learn?
Oh and btw could you recommend some tutorials on allocating new memory in process
in the context of game hacking to reproduce more complex Cheat Engine hacks in C++?
For now I mostly overwrite the code with NOPs.
