Nuclear-Core Lib

by The_LostCraft

Nuclear-Core Lib gives mod developers a shared set of radiation and uranium mechanics, so nuclear-themed content can build on one foundation instead of reinventing it.

What it does

Nuclear-Core Lib is a library for developers rather than a content mod for players. Its main goal is standardization: radiation and uranium behave the same way across different mods that rely on it. Instead of each mod re-inventing its own radiation effects and uranium items, developers can build upon the shared foundation the library offers.

The library introduces radiation as a variable entity. Other mods can change that variable and use it directly, which lets them extend the shared basics in their own way. Players meet the library only through the mods that use it, and builders of nuclear content are its intended audience.

Nuclear-Core Lib is published for Forge on 1.20.1 only, with the latest file, 1.3, dated 2025-10-02. Client and server both need it. Its license is Creative Commons Attribution No Derivatives 4.0, and the mod is not open source, although its source code is publicly available.

Key features

  1. Standardized radiation

    Radiation is handled by one shared system, so mods that use it apply the same nuclear mechanics.

  2. Radiation as a variable

    Radiation is exposed as a variable entity that other mods can read and modify for their own effects.

  3. Uranium basics

    Uranium-related mechanics are provided as common groundwork that dependent mods can extend.

  4. Developer-oriented API

    The library is aimed at mod developers who want nuclear-themed content without rebuilding the basics.
