Lionfish API is L_Ender's Mod's new animation API, built on the internal animation API of Mowzie's Mobs and Citadel. It was created as Citadel grew heavier with miscellaneous functions and updates could face delays. Available for Forge and NeoForge on Minecraft 1.19.2–1.21.1.
For mods that need this animation API, rent your own Minecraft server and install Lionfish API with one click from its server panel.
