Mod Lionfish-API

Lionfish API, Very Light Animation API

Lionfish API is a technical library mod for Minecraft Java Edition that provides a lightweight framework for animated entities, models, and related visual behaviors. It is designed for other mods rather than adding standalone blocks, items, mobs, or dimensions, so its main role is to support a smoother and more consistent Minecraft server experience when a compatible project needs its animation functions.

Created for L Ender’s mod ecosystem, Lionfish API builds on ideas from Mowzie’s Mobs’ internal animation API and Citadel, while aiming to avoid unnecessary overhead. It supports Forge and NeoForge, works on the client and server, and is distributed under LGPL 3. BoxToPlay makes it a practical library for modpacks that depend on animated content.
