Resource Geodes & Catalysts
by DarkLotus781
Resource Geodes & Catalysts is a NeoForge world generation addon that adds renewable resource generation through configurable catalysts placed in underground geode-like structures.
What it does
Catalysts are unique blocks inspired by the ore and stone variants of the Create mod. Underground geode-style formations hold these blocks, and after activation they yield ores and other valuable resources, including materials from other mods. Activation requires an agitator: a Catalyst Agitator item in tiers 1 to 4 must meet or exceed the tier a catalyst needs. After activation, a catalyst regenerates its resources on a cooldown, and the mod shows visual feedback while the cooldown runs.
The mod is built around data. New catalyst types are declared in JSON files, which means a pack maker can add them without writing any Java; the shipped recipes remain in place, and KubeJS datapacks can replace them. Any vanilla or modded item can be set as a catalyst's agitator requirement, for example minecraft:gunpowder. The mod is open source under the MIT License and has no dependencies beyond NeoForge, with a wiki and a GitHub issue tracker. It is published for 1.21.1 only, and the server and every player need it, since the environment is client and server.
Key features
Data-driven catalysts
Catalyst types are described in JSON, covering what they generate, their activation requirements and their cooldown behavior.
Configurable cooldowns
Cooldown, shape and activation logic can be changed, so each catalyst can regenerate at its own pace.
Craftable catalyst core
A craftable item serves as the core used to create catalysts, and the default recipes can be overridden with KubeJS.
Integration with JEI and Jade
Catalysts and their blocks work with JEI and Jade out of the box, showing recipes and block information in game.

How it compares
Nether Geodes is a NeoForge option for 1.21.1 with a custom license and no open source code. Geodes Expanded is also NeoForge only for 1.21.1, but it is released under All rights reserved. RemoveGeodo goes the other way: it removes geodes rather than adding them, is open source under the MIT License, and covers 1.20.1 – 1.21.11 on Forge and NeoForge.
