Inventory hacking for pointermap peasant

[seergaze]

Hi legends, I'm a cheat engine peasant who only recently learned pointermap scans and I've managed to make simple HP/ammo/money/damage cheat tables

However I am having trouble finding stuff that doesn't change its value much, for example, grenades where you can only hold a maximum of 1, or rare items in RPGs that u only get once per play through

Basically I want to make "unlimited usable/crafting item cheats"

I would like some advice on how to approach making unlimited inventory cheats, bearing in mind I'm a complete noob when it comes to coding.
