Cobblestone Semantics
by istrikeboomi
Cobblestone Semantics is a Forge and NeoForge technology mod centered on automating cobblestone, with generators, a melter and a lava generator that turn cobblestone into power and lava.
What it does
The mod adds generator blocks that combine cobblestone, lava and energy to produce more of each. A cobblestone generator feeds a melter and a lava generator, and the power they supply is produced automatically from the cobblestone flow, so a small setup can run without manual input. Lava output is measured at 500 mB per 200 ticks of cobblestone, and a lava bucket produces 100,000 RF or FE per 200 ticks.
Armor and tools made from cobblestone, infused cobblestone and obsidian are included, and a backpack with tiers adds storage from 9 slots up to 27. Generator tiers run from Cobblestone through Dirt, Stone, Iron, Redstone, Gold and Diamond, each holding more cobblestone and producing it faster, with Tiered progression reaching from Diamond to Netherite. Delay times and energy output can be tuned in the config.
The server and every player need the mod installed. Files are published for Forge and NeoForge, with 18 release versions 1.12.2 – 26.2, and the license is All rights reserved, so the mod is not open source. Its source code and issue tracker are publicly linked.
Key features
Automated cobblestone generation
Generators produce cobblestone on a timer, and the output can feed melters or lava generators without manual transfers.
Seven generator tiers
Tiers run from Cobblestone up to Diamond, each with a larger buffer and a faster rate, such as 2,048 cobblestone at 4 per 5 ticks at the top.
Cobblestone and obsidian gear
New armor and tools are crafted from cobblestone, infused cobblestone and obsidian, and the blocks work as a strong decorative material.
Tiered backpack
The backpack gains storage from 9 slots to 27 slots as the player advances through the upgrade tiers.
