Manitor Lib
by M123Mc_Op
Manitor Lib is a NeoForge library for 1.21.1 that supplies shared animation systems and one built-in advancement, the Sculk Catalyst achievement, for other mods to build on.
What it does
Manitor Lib is a lightweight animator library intended to be used as a dependency by other mods. It provides core animation systems so that a mod can reuse one animation framework instead of carrying its own copy of the same code. The library also includes compatibility utilities for the mods that depend on it, and the author describes it as aimed at developers who want a simple integration with an optimized base.
Manitor Lib runs on the server only, so players join without installing it. It has to be present on the server for the mods that require it to work. Files are published for NeoForge 1.21.1, and the library is released under All rights reserved, so it is not open source. The current release is 1.0.0, first published on 2026-07-24.
Purple Crystal Java requires Manitor Lib. The Purple Crystal Java mod is the only catalog mod on the Modrinth page that depends on it, and its animated content and achievement feature rely on the animation systems provided here.

A built-in advancement is granted when a player obtains a Sculk Catalyst, adding a small gameplay bonus.
Achievement framework
A framework for custom achievement grants that dependent mods can use in addition to the built-in advancement.
