Only one per type of item system

[sluk]

sorry i dont really know how to explain it in a title so i think i will explain it here:
so for example in an RPG you cant wear 2 chest plates or even your full invetory so what i wanna say if you have already one chest plate and you want to take two there comes a warning that you cant wear 2 chest plates and and that you cant wear 2 chest plates

sorry i really dont know how explain it

usually it's done using item level. For example all chest pieces will have item level 1, all boots will have level 2, etc.
When you pick up an item, you check if you don't already carry an item with same level. If you do, you drop the picked item and write an error message.

I don't know how big level an item can have, so there may be some limitations. The other option then would be to create for example an array or hashtable where you save each item and define its class and use that for checking stuff.

It can also be done by using Warcraft 3 item types (Purchasable/Campaign/etc) or event items hp (but you need to make that nothing can damage items).

There is at least one system like that in the spell database.

EDIT: I don't seem to find it.
