Zine is a "Little Library" mod made to suit my (EightSidedSquare) modding needs. You may use it for your own projects but please do consider this entire library mod unstable as changes are likely.

Registration

RegistryHelper class with helper methods for all registries
RegistryQueue class for queueing the registration of values

Data Generation

Particle Texture data provider
Sound List data provider (made before Fabric API implemented a sould provider itself, I consider this one to be less verbose)

Advancements

Modify Advancement event
VanillaAdvancementModifications helper class for simple modifications to vanilla advancements (i.e. adding a food item as a requirement for the "Balanced Diet" advancement)

Animations

Extra interpolations derived from Geckolib

Sprite Atlases

Generator sprite atlas source for generating noise and gradient textures
Remap sprite atlas source for mapping multiple textures together given a base texture
Connected textures atlas source for stitching 5 textures into all connected texture permutations
Modify sources atlas source event
AtlasSourceUtil class
PalettedPermutationsAtlasSource extensions for modifying its values

Models

ModelsEvents.ADD_UNBAKED event for creating unbaked models on resource pack load
ItemModelEvents.BEFORE_BAKE event for modifying item models before baking (similar to the Fabric API implemtation, except this can resolve references to models)
ItemModelEvents.ADD_UNBAKED event for creating unbaked item models on resource pack load
Extensions for all vanilla unbaked item models for modifying their values
ConnectedBlockModel and FancyConnectedBlockModel classes
TessellatingBlockModel class

Misc

Noise-based spawn condition
Extensions for many predicates to modify their values
