BCLib — Guide

What It Provides

• Registration helpers for blocks and items, including whole material sets - complete wood and stone block families (planks, stairs, slabs, doors, signs, chests and more) registered from one definition.
• World-data management - per-world data storage with a save-data fixer and migration system that keeps older worlds loading safely after the mods update.
• Custom anvil recipes - a recipe type for items crafted on the anvil.
• Tag helpers - registering and populating common block/item tags shared by the team's mods.
• Config system - JSON-based configs for the team's mods (see Configuration).
• Custom portal-frame support - frame blocks tagged as portal frames are accepted by nether-portal logic, which is what lets dependent mods offer portals built in any shape.

None of this is visible in game unless a dependent mod uses it.

Which Mods Need It

Install BCLib only when another mod lists it as a required dependency:

• BetterNether - the BetterX nether overhaul - requires BCLib (and WorldWeaver).

BCLib itself requires WorldWeaver, which is listed in this post's Requires box.
