Learning Objectives

By the end, you’ll have a real Item resource you can reuse across your entire game.

0/6 done
Understand common item fields (icon, name, rarity, stack size, value).
Know which fields should be exported so designers can edit them.
Use @export to expose variables in the Inspector.
Use typed exports (enums/ranges) to constrain values safely.
Build Item.gd as a Resource with clean exported fields.
Create a few .tres items (potion, sword) and confirm they share the same script.
