Modonomicon FAQ

The Modonomicon item is typically given by the mod that ships the book, either as a starting item, a craftable item, or via a command. If you're the pack author, you can hand it out with a give command or place it in a loot table. Check the mod that provides the book for its specific acquisition method.

Hold the Modonomicon and right-click (use) it to open the guide interface. If nothing happens, make sure you're holding the correct book item and not a different mod's guide.

Blank pages usually mean the book's JSON content failed to load, often from a syntax error or a missing referenced entry. Check your datapack or mod's log for parsing errors and verify the entry and page files exist in the expected folder.

Create a JSON file for the entry in the book's data folder, then reference it from the book's category or index file. Each entry needs an ID, a title, and one or more pages with content.

Entries can be gated behind advancements, items, or other conditions defined in the entry JSON. Until the condition is met, the entry stays hidden or locked in the book. Remove the condition or grant the advancement to make it visible.

Yes, if the book content is defined through datapack JSON files rather than Java. You can add entries, pages, and categories by editing JSON, but the book itself must already be registered by a mod.

A category is a top-level tab or section in the book, an entry is a single topic within a category, and a page is one screen of content inside an entry. Entries can contain multiple pages that players flip through.

The book item only appears if the mod that registers it is loaded and the item is added to a creative tab or search index. If you're a pack author, add it to a creative tab or it won't show in search.

Modonomicon is a content and UI library, so clients generally need it installed to render the book interface. Check the mod's requirements for whether it's client-side, server-side, or both.

Modonomicon itself is lightweight since it mainly loads JSON content and renders a book UI. Lag is more likely from a very large number of entries or pages, or from other mods, rather than the book system itself.
