Ores4Gen
by aloyen07
Ores4Gen adds cobblestone, stone and ore generator blocks built from water, lava and other source blocks, and its config file controls what each generator produces.
What it does
Each generator is a block made from water, lava and a few specific source blocks, such as blue ice and soul soil for the basalt variant. Placed in the right combination, it produces cobblestone, stone, obsidian or basalt, and in some setups ore blocks including coal, iron, gold, diamond, emerald, lapis and redstone. Crying obsidian, glided blackstone and ancient debris are also among the generated outputs.
The spawn rates, ore types and other generation parameters are set in a config file, so a server owner can tune the output without changing the mod. A command reloads that config while the game runs and another shows information about the mod. The mod is aimed at players who want extra resources from generators, and it suits survival and modpack setups.
Files are published for Fabric only, for Minecraft 1.21.8. Either side can run it, and neither side needs it, so it can sit on a client, a server or both. The code is not open source and the Public links that exist are for the source code and issue tracker. Ores4Gen is released under a custom license.
