Intro :
Tired of your cobblestone generator always giving the same block? This mod tweaks it so generators can produce various stone types and even rare ores.
Features :
- The generators don’t just make cobble, they can also give you stone, diorite and a few other blocks.
- The odds of getting ores are balanced to keep things close to vanilla progression, nothing too crazy.
- Works fine in singleplayer and multiplayer, no special setup needed.
- Super lightweight: no extra items, no menus, no configs. Just drop it in and it’s ready.
- This mod is fully datapack-driven, which means you can add your own generators without touching the code.
How To Use :
It works very simply: start by building a regular cobblestone generator and let it produce its first block. Then, replace the block under the generated cobblestone with the one you want to use as a generator.
Advanced Generators :
Some generators require special setups to work properly :
- Generators with a hopper (🔗🖼️) : The block that defines the generator type must be placed under the hopper.
- Generators with a normal piston (🔗🖼️) : You need two blocks that define the generator type placed under the piston. Both blocks are required.
- Generators with a sticky piston (🔗🖼️) : The block above the sticky piston must be a glass block (any type of glass, tinted or not). In addition, you must place two blocks that define the generator type under the piston. Both blocks are required.
Create Custom Generator :
This mod is fully datapack-driven, which means you can add your own generators without touching the code. You can find an example datapack for Biomes O Plenty at the following URL :
