golem

Vanilla Copper Golems move to the nearest chest and check its contents by trial and error, and they keep no knowledge between trips. Golem adds a new block, the Memory Block, that a player places to start the system. A Golem that stores an item into a chest records that chest in the Memory Block it latched onto, so later sorting of the same item can check the remembered chests first instead of scanning the room again.

When a Golem finds that a remembered chest no longer holds the item, it removes that entry from memory. After a short search with no success, a Golem gives up and forgets what it touched, which keeps the memory from growing without limit. Breaking the Memory Block clears the stored memory. Several Golems sharing one block can pass along where items went, so they spread out instead of all checking the same chest. The author describes this as an attempt to make larger storage rooms practical while still keeping items sorted.

Golem requires Fabric API. It runs on the client and the server, so the server and every player need it. Files cover 1.21.9 – 26.1.2 for Fabric, with 0.1.2 for 26.1.2 as the latest build, and the mod is released under the GNU General Public License v3.0 or later, which makes it open source. Source code and an issue tracker are public.
