Spark Core
by SolarMoon
Spark Core is a NeoForge library that provides rigid body physics, a state machine system and a Bedrock-style model animation loader for other mods.
What it does
Spark Core bundles the ode4j rigid body physics library, the KStateMachine Kotlin state machine library, and a Bedrock version model animation loader with controllers. Mod developers can use these pieces for physics, state-driven behavior and preset animations such as walking and running. Spirit of Fight requires the library. The mod is Client and server, so servers and every player need it installed, and it is released under the MIT License as open source, with files for 1.21.1 only on NeoForge.
