Smarter Copper Golems

Smarter Copper Golems enhances the vanilla Copper Golem behavior introduced in Minecraft 1.21.9 with intelligent item sorting capabilities.

The Problem

In vanilla Minecraft, when a Copper Golem picks up an item and tries to deposit it in a chest:

• It visits up to 10 chests looking for an exact match (same item type, name, and enchantments)
• If it can't find a perfect match after 10 attempts, it wanders around aimlessly for 7 seconds
• Then it forgets all visited chests and starts over

This behavior wastes time and results in poor item organization.

The Solution

This mod makes Copper Golems smarter by implementing intelligent chest sorting:

Smart Sorting Algorithm:

• When a Copper Golem reaches 10 visited chests (or starts wandering), it evaluates all visited chests
• Each chest receives a similarity score based on its contents:
  • +100 points: Contains the exact same item (type, components, enchantments)
  • +50 points: Contains the same item type
  • +10 points: Contains items from the same category
• The golem deposits the item in the chest with the highest score
• If no suitable match is found (score = 0), it uses the first chest with available space

13 Item Categories:

• Building Blocks (planks, stone bricks, logs, wool)
• Ores & Minerals (beacon payment items, coal)
• Tools & Weapons (swords, axes, pickaxes, shovels, hoes)
• Food (all edible items)
• Redstone (redstone, repeaters, comparators, pistons)
• Plants (saplings, flowers, seeds)
• Combat (armor pieces)
• Dyes (all dye colors)
• Potions (potions, bottles, brewing items)
• Books (books, enchanted books)
• Rails (rails, minecarts, boats)
• Music (music discs, goat horns, note blocks)
• Miscellaneous (everything else)

Features

• Zero Configuration: Works out of the box - just install and play
• Vanilla-Friendly: No new items, blocks, or GUIs - pure behavior modification
• Performance Optimized: Lightweight event-based system with minimal overhead
• Multi-Version Support: Compatible with Minecraft 1.21.9, 1.21.10, and 1.21.11
• Server-Side: Works on both single-player and multiplayer servers

Use Cases

Perfect for automated sorting systems where Copper Golems:

• Organize your storage room by item type
• Sort loot from mob farms into appropriate chests
• Maintain categorized storage without complex redstone contraptions
• Create self-organizing warehouses with natural mob behavior
