Smarter Copper Golems

In vanilla Minecraft 1.21.9, a Copper Golem picks up an item, tries to deposit it in the nearest chest and wastes time when that chest does not fit. This mod replaces that behavior with a sorting routine. The golem checks up to 10 chests for a chest matching the item type, name and enchantments. If none matches after 10 attempts, it wanders for about 7 seconds, forgets the chests it visited and starts over.

Each chest the golem evaluates gets a similarity score from its current stock. A chest holding the exact same item type with the same components and enchantments scores 100 points, one holding the same item type scores 50, and one holding items from the same category scores 10. The golem then favors the chest with the highest score, which lets chests of similar goods grow together. The mod is intended for automated sorting systems where Copper Golems carry items between storage rows.

The mod runs on Fabric and NeoForge for 1.21.9 – 1.21.11, and it is released under All rights reserved, so it is not open source. Both the server and every player need it, because the golem behavior is driven from the server side and clients must match it.
