Concepts
This mod leans extensively on Player Skills by creating and consuming the Skill-based Restrictions. Out of the box, this
mod can restrict whether an item can be equipped, held in inventory, crafted, visible in JEI or REI, and whether it can
be identified in a tooltip. Note that this does not alter interactions with placed items (e.g. a placed bed will still
be interactable by a player who can't craft one). However, Block Skills provides that complementary functionality.
When using this with JEI or REI, please be sure to disable the vanilla recipe book as the restricted items can appear
there despite being uncraftable as this mod does not remove any actual recipe. Instead of removing recipes, it restricts
the crafting result when a player tries to craft an item and hides the recipes in JEI/REI.
Caveats
JEI integration does not remove recipes related to the unconsumable flag. It does hide the recipes from right-clicking
on the ingredient. However, it does not remove the recipe itself -- only unproducible does that. That is, a crafty
player could view a recipe that produces the item, then right click on the produced item to see what recipes it can be
with which it can be consumed.
