Base Metals

Base Metals 2.6.0.112021 — Minecraft 1.12.2

Before upgrading

• Back up worlds and configuration. Install MMDLib and OreSpawn 4.1.0.112021 or newer in the 4.x line on both client and server.
• Old configurations without a content mode stay in High Fantasy. Existing items and block IDs are retained.
• OreSpawn is now the only Base Metals ore generator. Use OreSpawn overrides or world settings to disable its rules when another mod generates the ores. The old MMDLib world-generation switches no longer control Base Metals.

Gameplay fixes

• Metal nuggets and powders no longer burn as furnace fuel. Coal and charcoal forms keep their intended fuel values (#473).
• Doors and trapdoors have distinct recipes. Vanilla-material additions such as Diamond and Gold doors are registered and available as intended (#474).
• Base Metals Adamantine no longer shares the Adamant alias with TAIGA (#467).
• Fishing rods use their material's durability and retain vanilla fishing wear rules (#467).
• The Steel rail recipe produces 16 rails, matching the vanilla recipe (#467).
• Crossbows fire bolts on the server, so hits damage their targets. Launcher and ammunition materials both contribute to ranged damage. Bolts use a valid projectile texture, and picked-up Base Metals arrows keep their identity (#467).
• Armor effects count equipped pieces correctly and no longer depend on an undamaged stack. Aquarium's underwater effects and Starsteel's movement bonuses now apply as intended (#470, #450).
• Tinkers casting and alloy registration skip disabled or missing materials and fluids instead of crashing, including disabled Prismarine additions (#455).
• Hoes report the tool-material name expected by Ancient Warfare 2 (#449).
• The native OreSpawn provider replaces the old plugin and fallback generator. Its eleven rules retain their defaults and customized migration values, and can be disabled without duplicate fallback generation (#448, #428).
• Recipe-book unlocks recognize matching Ore Dictionary ingredients. Recipes are grouped by their result instead of merging whole weapon and tool families.
• Plate repair requires exactly one damaged armor piece or shield and one matching plate. It preserves NBT, rejects extra ingredients, and no longer appears as a misleading plate-only recipe in the recipe book.
• Restored the 18 historical gameplay achievements, including Juggernaut, SCUBA Diver, and Moon Walker, with saved advancement progress.

Configuration

• Added High Fantasy and Low Fantasy content modes. High Fantasy keeps the historical content; Low Fantasy limits acquisition to suitable material forms. Items remain registered and available in creative mode in both modes.
• Crafting, processing, trades, chest loot, and supported integrations respect the selected mode. Clients and servers must use the same effective mode.
• Added the configuration screen to Forge's Mods list and OreSpawn's cog. It has localized labels and help in all 18 language files, cancellation, reset controls, restart guidance, and warnings before disabling generated ores.
• Content modes are installation-wide settings. They do not change OreSpawn distributions or overwrite existing world profiles.

Build and delivery

• Modernized the Minecraft 1.12.2 build on ForgeGradle 7, Gradle 9.6.1 and checksum-pinned Java and mod dependencies.
• Added deterministic release archives, artifact auditing, Eclipse launch generation, packaged Forge runtime qualification and guarded GitHub Actions release delivery.
• Isolated ordinary Eclipse launches from compile-only integration APIs, so optional mods such as CoFH Core are not accidentally loaded without their dependencies, while preserving Forge's order-sensitive runtime classpath.
• Updated the development target to Forge 14.23.5.2859 and OreSpawn 4.1.0.112021 while retaining Java 8 game compatibility.
• Replaced the retired build services with pinned GitHub Actions checks and a guarded Maven, CurseForge, and GitHub release workflow (#468).
• Split the build scripts by purpose and cleaned up source layout and comments.

1. (@dshadowwolf) Masses of bug-fixes
2. (@dshadowwolf) Move vanilla extensions out of MMDLib - the lib should be providing anything but raw materials
