A general purpose, modularised api for beta 1.7.3. The mod adds nothing on its own, though adds a bunch of systems for modders to use, and thus many beta 1.7.3 mods may require it.

Supports modders with:

• Adding custom tiles (aka blocks), items, entities, tile entities, features, biomes, recipes, translations, and terrain
• A vanilla-checker
• A world type system which is enabled if a mod registers a custom world type
• Registries, registry remapping, registry sync
• A "decorator" system for modders who want a more modern worldgen approach
• Fabric's Event API
• Config system that uses the ZoesteriaConfig library
• Networking API
• Commands API
• Some Interaction and Lifecycle events
• An attached data system for ItemInstances and Level Properties (level.dat)
• Includes paulevs' corelib and an Atlas API by chocohead for models. These are used to power a modern-esque model json system for simple tile and item models and textures.
