How it works

1. Press K in-game to open the editor.
2. + Add Recipe to pick a recipe type
3. Click a slot to search or type an id, set a tag/fluid, count, chance, or data components. Right-click a slot to clear it
4. Set recipe parameters on the side panel
5. Hit Export and review the generated files, then write them to kubejs/server_scripts/.

Adding your own recipe types

Third-party mods or datapacks can register their own recipe types by dropping a JSON layout file under assets/<namespace>/kjsgen_layouts/ (slot positions, decorations, and a template string with {slot:KEY} / {inputs} / {outputs} / {param:KEY} placeholders), or by firing a Java codegen handler off RegisterRecipeTypesEvent on the mod bus.
