The Block Keeps Ticking
by MagicJinn
The Block Keeps Ticking keeps block entities and crops progressing in chunks that are not loaded, so farms and furnaces continue working while a player is far away.
What it does
The mod simulates growth and processing for block entities in unloaded chunks. Furnaces, campfires and brewing stands finish their work, and passive mobs keep growing. The simulation is an approximation: some precision is lost during simulation, and decay progression is handled the same way.
Installation needs Fabric API and YetAnotherConfigLib (YACL) on the server, and Mod Menu is optional for editing settings in-game. The mod is server-side only, so players join without installing anything. Files are published for Fabric alone, with 10 release versions 1.21.6 – 26.2 and 1.2.1 for 26.2 as the latest build. The code is open source under the MIT License.
Key features
Unloaded block entity simulation
Furnaces, campfires and brewing stands keep working after their chunks unload, then catch up when they load again.
Crop and sapling growth
Wheat, carrots, potatoes, beetroots, torchflowers, pumpkins, melons, nether wart and cocoa beans grow while the player is away.
Configurable values
Server owners can adjust the simulated values in the config file at config\the-block-keeps-ticking.json, through Mod Menu or YACL.
Developer API
A small API lets other mods register their own ticking objects so they are simulated in unloaded chunks.
