About this project
What does Onioning API add?
🧅 Onioning API (1.21.1 / NeoForge)
Onioning API is an advanced command-scripting engine that transforms standard Minecraft commands into a powerful, multi-layered visual programming language for magic, automation, and server administration.
By utilizing a nested "onion-skin" syntax, this utility allows developers, mapmakers, and server admins to nest functions inside one another, cache persistent coordinates to disk, and deploy fully standalone RPG spells directly inside item NBT data.
