Checklist

I have fully tested the proposed changes and promise that they will not break everything into chaos.
I have also tested the proposed changes in combination with various popular addons and can confirm my changes do not break them.
I have made sure that the proposed changes do not break compatibility across the supported Minecraft versions (1.16.* - 1.20.*).
I followed the existing code standards and didn't mess up the formatting.
I did my best to add documentation to any public classes or methods I added.
I have added Nonnull and Nullable annotations to my methods to indicate their behaviour for null values
I added sufficient Unit Tests to cover my code.

ToDo

add tests for all lines of the new code
Add comments
performance test

Slimefun preview build

A Slimefun preview build is available for testing!
Commit: 9f01d73f

Note: This is not a supported build and is only here for the purposes of testing.

Testing required

This will need just general Slimefun testing. Some areas to specifically cover:

Can use a variety of items
Can craft items in enhanced crafting table
Can build multi block
Can craft with ancient alter
Backpacks still work
Cargo can move items as normal

Boomer:

I even added teleporting, basic dust farming, tested a few nodes going thru cargo, and everything seems to work as expected. backpacks are fine. no issues on ancient altar. all i tested with though was core slimefun. no addons or outside plugins. Added multiple power generators, geo mining, teleporting with the gps pad, and everything seems to be running as expected.

the environment was 1.20.4, paper version 405. probably need to update that but, eh for now

the type check is the third check,

why do a type check again here?

Good optimization but in its current form this will break a lot of machines because it is missing a check for the amount and special handling for some items.

The "checkLore" option is ignored here

We already check lore in the method. We don’t specifically need to check for it with a boolean

The option exists in the gui yet it has no effect on the check.

Type check is the first, so items with changed item type (e.g. explosive pickaxe is diamond pickaxe, and using the improvement forge from FoxyMachines to upgrade it to netherite) will not match.
maybe we can have some sort of whitelist for tools and weapons. and other type mismatches will return immediately.

WalshyDev · 2024-02-25T15:06:27Z

An allowlist just leads to unmaintable again annoyingly

I'd say just do this when we know it isn't an Slimefun item but that will slow down a bunch...
