[1.21.1] - 0.1.2 - 29.11.2025

Changed

Namespace Migration (Vanilla Backport Preparation) - 698 file changes

• Registry namespace changed: All vanilla backport features now use minecraft: namespace instead of copperagebackport:
• Affected items: Copper Tools, Copper Armor, Copper Nugget, Copper Horse Armor, Spawn Egg
• Affected blocks: Copper Chests, Copper Golem Statues, Shelves, Copper Torch, Copper Lanterns, Copper Chains, Copper Bars
• Affected entities: Copper Golem
• Copper Buttons: Remain at copperagebackport: as they are not in vanilla Minecraft 1.21.10
• Backwards compatibility: Old worlds with copperagebackport: IDs are automatically migrated on load
• Resource files: All recipes, loot tables, tags, models, and textures updated to use minecraft: namespace

Copper Chest Recipe (Vanilla 1.21.10 Style)

• New recipe: Copper Ingots surrounding a Chest now craft a Copper Chest (matches vanilla 1.21.10)
• Removed recipes: Exposed, Weathered, and Oxidized Copper Chest crafting recipes removed
• Oxidation only: Oxidized chest variants can now only be obtained through natural oxidation over time

Added

Lightning Rod Weathering (Backport from 1.21.10)

• Weathering system: Vanilla Lightning Rod now oxidizes over time like other copper blocks
• 8 new variants: Exposed, Weathered, Oxidized + Waxed versions of each
• Mixin integration: Vanilla minecraft:lightning_rod is extended to support weathering
• Waxing support: Use honeycomb to prevent oxidation
• Scraping support: Use axe to remove wax or revert oxidation
• Full functionality: All variants retain lightning attraction and redstone output

Copper Armor Trims

• Smithing Table support: Copper Armor can now be trimmed in the Smithing Table
• Darker trim variant: Copper Trim on Copper Armor uses a darker color palette for visibility (matches vanilla behavior)

Mod Support

• Amendments compatibility: Copper Lanterns now extend LanternBlock for automatic Amendments support (wall placement, falling behavior)
• SophisticatedStorage support (NeoForge): Copper Golem can now use SophisticatedStorage Chests and Barrels as item destinations (works with all tiers: Wood, Copper, Iron, Gold, Diamond, Netherite)
  • Chests play opening/closing animations when accessed by Copper Golem
• IronChests support (NeoForge): Copper Golem can now use Iron Chests containers as item destinations (works with all types: Copper, Iron, Gold, Diamond, Crystal, Obsidian, Dirt + trapped variants)
  • Chests play opening/closing animations when accessed by Copper Golem
• ConnectibleChains support (Fabric only): Copper Chains can be connected between fences and walls like vanilla Iron Chains
  • Note: No NeoForge version available as ConnectibleChains is Fabric-only for 1.21.1

Localization Support

• Crowdin integration: Added automatic translation download from Crowdin during build process
• Community translations: Everyone can help translate the mod at https://crowdin.com/project/copper-golem-legacy

Fixed

Copper Golem

• Container selection order: Fixed Copper Golem selecting containers in wrong order when multiple containers are equidistant. Now correctly matches vanilla 1.21.10 behavior by sorting BlockEntities by BlockPos.hashCode() in descending order. This also fixes selection across chunk boundaries.

Copper Chest

• Loot table behavior: Fixed Copper Chest to match vanilla behavior - chest contents now drop on the ground when mined instead of being stored in the item (like normal chests, not like Shulker Boxes)

Copper Button

• Oxidation while pressed: Copper Buttons no longer oxidize while they are pressed, preventing them from getting stuck

Build System

• BOM detection and removal: Added automatic UTF-8 BOM detection and removal task for all mod files across all versions. This prevents encoding issues that could cause compilation problems or runtime errors.
