BjornLib
BjornLib is a shared code library for Forge and NeoForge, offering helper systems that other mods build on: abilities, particles, lightning and leveling.
What it does
Most of BjornLib is generic code meant for other mods to call rather than a set of blocks or items for players to use directly. It provides an ability registry that handles some related events, a particle builder that can render glowing particles with a magic style and includes several default particles, a lightning builder for generating lightning effects, and a leveling builder that can apply level-ups to mobs.
The library runs on client and server, so both the server and every player need it when a mod that depends on it is installed. Files are published for Forge and NeoForge across three game versions, 1.20.1 – 1.21.1, with 1.0.20.11 for 1.20.1 as the latest Forge file and 1.0.88 for 1.21.1 as the latest NeoForge file. BjornLib is not open source and is released under All rights reserved. An issue tracker is available for reporting problems.
Key features
Ability registry
A registry for abilities that also handles some related events, so dependent mods can attach ability behavior without writing their own event code.
Particle builder
Builds particle effects with glowing rendering and a magic style, and includes several default particles ready to use.
Lightning builder
Creates lightning effects through a builder interface, for mods that need configurable bolts.
Leveling builder
Gives mobs level-up behavior, letting dependent mods define how creatures gain levels.

Use cases
Mods that need shared helpers
Mod authors can call BjornLib's builders instead of duplicating particle, lightning or leveling code in each project.
Who it’s for: Mod developers who want ready-made particle, lightning, ability and leveling helpers, and players who run mods that depend on BjornLib, such as Dragon Mounts: More Dragons, SoulLight and The Gifted.
