WunderLib (Unofficial Forge Port) — Minecraft 1.20.1
This project is an unofficial port of WunderLib to Forge for Minecraft 1.20.1.
It exists to make mods that depend on WunderLib available on Forge for modern Minecraft versions.
Forge only (not Fabriс).
What this project does
Provides the WunderLib library on Forge for Minecraft 1.20.1 (a dependency/utility library used by other mods).
The goal is to keep functionality as close to upstream as possible, with only porting/compatibility changes where required.
Why download it

Required on: both client and server.
How this project differs from the original
