Legacy Duplicator Mod

Back during the 1.12.2 modding days, I used MCreator to make a mod called the Duplicator Mod. Its purpose was straightforward: It added machines that would allow you to duplicate blocks and items. Unfortunately, sense it was made with MCreator (and way back in 1.12.2) I was pushing MCreator and causing bugs and using not so great code, which wasn't helped by how inexperienced I was. Despite this, I had uploaded it to the MCreator website, and to my shock, it got thousands of downloads and many seemed to like it! Now that I have somewhat decent modding experience and can make mods without MCreator, I have decided to remake my old mod today for 1.21.1. Featuring better code and (kind of) better textures, here's my remake of my legacy duplicator mod!

Features

Basic Duplicator

The Basic Duplicator will duplicate any block placed on top of it to underneath it when interacted with a duplicator stick. The Basic Duplicator does have some blacklisted blocks:

Item Duplicators

The Item Duplicators all have varying amounts of items they can duplicate. By placing your item in the leftmost slot and a duplicator stick in the bottom slot, you can click the duplicate button to duplicate your item. Upgrading your item duplicator will get you a bigger max capacity. Item duplicators also have some blacklisted items:

Infiniduplicator Stick Part Maker

I know it's not a great name, but it is what I called it back in the 1.12.2 version. This block will take in certain items (revealed when hovering over the i icon), and upon hitting the craft button will create a infiniduplicator stick part.

Unduplicatable Item One & Two

These are special items that are purely designed for not being duplicatable (don't ask why, apparently several years ago me really wanted them) and they cost a ridiculous amount of diamonds, at 9 diamond blocks, and then 9 of the previous item.

Infiniduplicator Stick

The most OP item in the mod, this item acts as a replacement for the duplicator stick, but lasts forever. To get this you'll need 3 infiniduplicator stick parts and 6 duplicator sticks.
