how to make crafting system

how do I a make crafting system for my tarrainia shooter style game

It is possible, but really complex. Maybe @“JR 01” COuld help with this? He might know a shorter way.

Advance Inventory:

Its just knowing what is in each slot/save at a time. I plan on redoing the advance example eventually.
If you want a menu next to the player, then that’s even more work.
