About this Mod

This is a core mod for all my mods. The mod does not add any new gameplay content, its only a library mod that anyone can use and makes some things for developers much easier.

What does the library:

This library-mod adds several new utilities for developers, such as helpers for recipes, loot tables in datagen and methods for blockstates and item models in datagen. It also adds a new tool tier registry that makes registry a new tool set tier much easier with much less code thanks to the ToolSetBuilder. It also adds a way by the TieredWeaponBuilder to registry a new weapon type and automatically making one weapon of the same type for each tier. The mod also adds new biome tags that include biomes of Biomes O'Plenty, Regions Unexplored and Terralith, somethind very useful for custom structures and biome modifiers.

For mod developers:

Anyone can use this mod as a dependency in your own mod, just added as a normal dependency.
