About this project
What does MonoLib add?
**Use the most recent version of your preferred mod loader!
MONOLIB DOES NOT PROVIDE ANY NEW GAMEPLAY, BLOCKS, ITEMS, OR ENTITIES.**
MonoLib is the cornerstone library for mods published by Lupin and authored by Jason13, designed to decrease code repetition across many projects. This library is open for use by anyone, but it's designed around our needs specifically. This mod has many similarities to Botania by Vazkii, Collective by Serilum, and Bookshelf by DarkhaxDev; from event callbacks and commands to registration binding, there's plenty of utility provided.
MonoLib is released as loader-specific jar files, which can be imported via CurseMaven.
MonoLib only being supported for Minecraft versions 1.20.1, 1.21.1, and 26.1.2 currently.
Common is now easily consumable, as it is released via GitHub Releases! Check out the source code for how to use it in your project, or open an issue/contribute!
This project was made possible via these previous works:
Collective, a shared library with common code for all of Serilum's mods https://github.com/Serilum/Collective
Botania, a tech mod themed around natural magic https://www.curseforge.com/minecraft/mc-mods/botania
Bookshelf, a collection of code, frameworks, utilities, and other resources https://www.curseforge.com/minecraft/mc-mods/bookshelf
Forgix, a Gradle plugin/an Architectury addon to merge mod-loaders into one jar! wahh technology https://github.com/PacifistMC/Forgix
