CobbleGen Alehouse
by choco422
CobbleGen Alehouse adds nine tiers of cobblestone generators for Fabric, built to produce cobblestone at high rates without the entity lag that drops can cause.
What it does
Each generator tier is a separate block with its own custom 3D model, so the generators fit a vanilla look rather than standing out as machines. Drops are calculated inside the generator instead of being spawned as item entities, which keeps dropped items from piling up on the ground and slowing the server. A generator pushes its output directly into a storage block placed above it, so a chest or hopper line is not needed.
The generators have a smart buffer. When the inventory above a full generator is full, cobblestone is kept in an internal buffer that can hold four times the generation rate. Output resumes once storage has room again. Tiers produce one, four and sixteen blocks per second at the lower end of the range, and the upper tiers are meant for large builds.
The mod is client and server, so the server and every player need it. It is released under the MIT License and is not open source. Files target Fabric for 1.21.8 – 1.21.11, with 1.0.2 for 1.21.11 as the latest build.
Key features
Nine generator tiers
Nine tiers of cobblestone generators are available, each with a model of its own, for players who want steady stone output.
Internal drop calculation
Drops are resolved inside the generator, so no item entities are spawned on the ground and entity lag is avoided.
Direct output to storage
Each generator pushes its cobblestone straight into the container above it, with no conveyor needed.
Smart buffer system
A full storage above keeps cobblestone in an internal buffer holding four times the generation rate until space opens.
Stone Nether Star item
A Stone Nether Star item is added as an ingredient for the upper generator tiers.
