User information:

This is a library mod that provides utilities for modding Hypixel Zombies on newer versions of Minecraft. While this mod alone does track game state for Hypixel Zombies, none of the components are visible directly to the player. You should likely have been required to install this mod as a dependency of another mod, such as Zombies Utils v2.0.0+.

Developer information:

The library is actively maintained and will ideally provide all the internal functionality for Zombies, except for any HUDs / configs. The (subjectively) important components are already available!

To get started using the library, take a look at the intended interfaces in the bundled zombiesutils-api.

A maven package is available in my repository (https://git.stachel.xyz/api/packages/zombies/maven) under group id xyz.stachel and artifact name zombiesutils-api, matching the version of zombiesutils-core. See also the package in the web ui.

Major / minor version updates may change the interfaces, patch version updates may change the backend implementation but not the interfaces or their usage. Actually breaking changes to existing api are rare and most changes have been purely additive.

Most likely you want to depend on zombiesutils-api at compile time, but zombiesutils-core in your fabric.mod.json.
