[1.21.1] - 0.1.3 - 30.11.2025

Added

End Flash Effect

  • End dimension lighting: Ported the End Flash visual effect from Minecraft 1.21.10
    • Periodic sky flashes that illuminate the End dimension with a purple tint
    • Directional flash source visible in the sky with additive blending
    • Spatial audio that plays from the flash direction
    • Complete lightmap system that applies purple sky lighting and block brightness boost during flashes
    • Dragon fog compatibility: Flash intensity reduced by 1/3 during boss fight
    • Respects "Hide Lightning Flashes" accessibility option
    • Doesn’t work with shaders because End Flash doesn’t exist in 1.20.1; it was only added in 1.21.4.
    • Iris/OptiFine only provide the endFlashIntensity uniform on 1.21.4+

Fixed

Shelf Rendering

  • Banner display: Banners on shelves are now displayed larger with correct positioning

Fabric Disconnect Crash

  • Registry sync crash: Fixed client crash (NullPointerException in Screen.tick) when disconnecting from a multiplayer server on Fabric
    • Root cause: Fabric's RegistrySyncManager unmaps minecraft: namespace entries on disconnect, leaving null references
    • Solution: Cache all minecraft: namespace entries during registration and restore them before Fabric's cleanup via Mixin and event hooks

Data Load Errors

  • Tag references: Fixed golem_target_chests tag referencing old copperagebackport: IDs instead of minecraft:
  • Recipe syntax: Fixed copper_chest.json recipe using incorrect key format (raw string instead of { "item": … } object)
  • Conditional recipe: Added Fabric/NeoForge load conditions to pale_oak_shelf.json so it only loads when VanillaBackport is present

Added

Copper Golem Statue Comparator Support

  • Comparator output: Copper Golem Statues now emit a redstone signal when read by a Comparator
  • Signal strength: Returns 1-4 based on the statue's pose (Standing=1, Running=2, Sitting=3, Star=4)
  • Through-block reading: Comparators can read the statue's signal through a solid block (matches vanilla 1.21.10 behavior)

Mod Compatibility

  • Friends and Foes support: Added conversion recipes to convert Friends and Foes Lightning Rods to CopperAgeBackport Lightning Rods
    • Converts all 7 variants: Exposed, Weathered, Oxidized, and their Waxed versions
  • Lightning Rod Oxidation config: Added config option to disable Lightning Rod oxidation for compatibility with mods like Friends and Foes
    • Found in Config Menu under "Compatibility" → "Lightning Rod"
  • Amendments support: Copper Torch now works with Amendments "Torch Holding" animation
    • CopperTorchBlock now extends TorchBlock for proper mod detection
