Building a Complex Inventory System

This inventory took a lot. The code behind it is huge. Honestly,

I never thought I'd be able to write that much code in a single script. For someone who's

not a full-time programmer, it feels like a big milestone. Talking about functionalities,

you can drag items around, split stacks while holding shift, and merge them back

again. There are special types of items too. Ones that can be equipped,

and of course, some that can't. You can't equip something unequippable, like an empty vial.

Makes sense, right?
