Yung’s API is a world-generation API commonly used by Yung’s mods and a variety of other mods. It has collections of shared methods and data abstractions for data-related stuff including JSON.

For players, just install this like any other mod. For developers, you can include the files in your developer environment. The mod by itself does very little but is used for other mods.

This was originally designed for Yung’s mods, but Yung encourages use for other mod developers. Some of the features held by Yung API are:

A new Jigsaw Manager that has a custom pool of element types with various settings that perform better (Can see in Yung’s Better Dungeons Source code)
Automatic Registration on 1.18 via an annotation (@AutoRegister and a bunch of children annotations/interfaces or classes) that lets you register with just a field so long as you include the value() method.
Features for locating structures
Codec Helper making new Codecs more easily
JSON Parsers templates as Java Interfaces which can be used for making things like Java Beans
Various Java Services
Maths utilities focusing on Vectors and Columns positions
Noise Library
Block and Item randomisers called BlockStateRandomizer and ItemRandomizer make it easy to have different variations of blocks or items in a structures
Newer versions in some cases (at least in Fabric), also come with Javassist for Manipulation and Reflection Utils and a bunch of other stuff

If you need support, you can always join Yung’s Discord Server . It is compatible with both Minecraft Forge and FabricMC/QuiltMC and uses the MultiLoader Template to target all 3, as does most of Yung’s other mods (Yung is likely one of the biggest users of the MultiLoader Template) meaning that is likely the recommended way to use it, though you can likely use it in almost any environment.

The Official Yung Mods that use this are:

YUNG's Better Caves v1.1 and on 1.16.4 and newer
YUNG's Better Mineshafts v2.0 and on 1.16.4 and newer
YUNG's Better Portals []
YUNG's Better Strongholds
YUNG's Better Dungeons
YUNG's Better Desert Temples
YUNG's Better Ocean Monuments
YUNG's Better Witch Huts
YUNG's Bridges
YUNG's Extras
Traveler's Titles []
Paxi [](Despite not having anything to do with world generation)

Some non-Yung mods use this such as add-ons for Yung Mods.
