About this Mod
This mod adds a single block to the game, the "Generator". By default, it passively generates Cobblestone every second while having lava and water buckets inside.
You can view how the generator works in the Gallery page.
It also offers a new recipe type, so that you can create your own recipes via datapacks! The format is as follows:
{
"type": "generator:generator_recipe",
"ingredients": [
{
"item": "minecraft:lava_bucket"
},
{
"item": "minecraft:water_bucket"
}
],
"time": 20,
"output": {
"count": 1,
"item": "minecraft:cobblestone"
}
}
Note: The ingredients are not positional- they can be in either of the slots
It also supports Create's limestone from lava + honey and scoria from lava + chocolate natively and doesn't need to be setup. This mod has also been tested with Create's chutes, belts, funnels, etc.
Please note: this is my first ever public Fabric mod, so issues/bugs are to be expected

Generator server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.2). You can switch loaders with one click in the panel.
Is Generator compatible with fabric?
Generator officially supports fabric for Minecraft 1.20.2, 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Generator – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Generator consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
