What it does

Continuum Core is a community-maintained NeoForge port of the Mantle shared library, written by justduck and built for Minecraft 26.1.2. It keeps the mantle mod id so that dependent mods continue to load against it. The port focuses on the library surface that a current Tinkers port needs, and historical integrations and APIs are only considered supported where the port has been tested.

The library includes registration helpers that wrap objects, data generation helpers for resources, recipes, tags and loot, and utility classes for fluid transfer, inventory handling and recipes. Client model helpers are updated to current NeoForge and Minecraft APIs. JEI integration is supported at compile and runtime, since the port still relies on a few Mantle-side integration points. The mod is released under the MIT License and is open source, with the original Mantle project credited to SlimeKnights, whose upstream releases remain the reference for the original code.

Key features

  1. Mantle registration helpers

    Wrappers around registered objects make it simpler for dependent mods to declare their content.

  2. Data generation helpers

    Helpers cover generated resources, recipes, tags and loot tables, with output written under src/generated.

  3. Fluid and inventory utilities

    Utility classes for fluid transfer, inventory handling and recipes are carried over from Mantle for the port.

  4. Updated client model helpers

    Client-side model helpers are adjusted to the current NeoForge and Minecraft APIs used by the port.
