CraftDen1al

The mod is a server-side plugin that refuses some crafting operations on the client. A recipe that is blocked still shows its result in the crafting grid, but the item bounces back when a player tries to take it out, so the recipe cannot be completed. Recipes are described in a craftden1al.json file that the plugin reads once it starts, and the file is matched against the shape of each shaped recipe in the grid.

Setup is handled entirely by the server owner: the pattern file is edited, the server is restarted, and players re-enter the world. Client-side loading is useful for singleplayer worlds, where the file takes effect at once, while in multiplayer the change applies only when the mod is loaded on the server. The file is written in JSON, and a syntax error or an invalid item ID makes the plugin skip the file and leaves the recipe list unchanged.

The mod is published for Legacy Fabric and for the Paper, Spigot, Bukkit and Purpur server platforms, covering 46 release versions across the 1.4 – 1.12.2 range. The latest Legacy Fabric file is 0.0.5 for 1.11.2, dated 2024-12-08. The code is released under the GNU Lesser General Public License v3.0 or later and is open source, and the source, issue tracker and wiki are public.
