End-to-End Registration Tutorials

MBD2 21.1.1

These tutorials connect registration phase, authored definition, recipe creation, restart/reload behavior, and runtime verification. Follow one path from beginning to end before combining APIs.

Every tutorial ultimately produces a registered definition that opens and behaves like this editor-authored machine.

Pick a tutorial

Goal	Tutorial
Ship definitions and built-in recipes inside a Java mod	Java: machine, recipe type, and recipe
Learn the exact KubeJS startup/server split	KubeJS: registry and recipe scripts
Build a complete editor machine but keep pack recipes scriptable	Editor + Java + KubeJS hybrid

KubeJS-only boundary

KubeJS can create bare single / multiblock definitions, but 21.1.1 exposes no supported machine-authoring API for states, renderers, Traits, UI, recipe logic or multiblock patterns. A KubeJS-created shell proves registration; an operational machine comes from the editor or Java.

Machine behaviour without any of this

If what you want is behaviour rather than a new machine — redstone control, an overclock, a bonus output — bind a built-in blueprint instead. No script, no mod, no restart.
