ZeroCore2 Wiki & Guide
A guide to ZeroCore2, a multiblock-structure and GUI/widget library and framework for Minecraft mods. Covers what the library provides, which mods depend on it (such as Big Reactors), and how developers use it.
Overview
ZeroCore2 (mod id zerocore) is a library and framework for Minecraft mods. Its headline feature is a complete multiblock-structure system - the code that lets a mod build a large machine out of many individual blocks that validate, assemble, and then behave as a single machine. Alongside that it bundles shared systems that mods reuse instead of writing from scratch: network and packet handling, a config system, persistence helpers, and an interface/widget toolkit for building the GUIs and control panels those machines use.
ZeroCore2 has no player-facing content of its own - it adds no blocks, items, mobs, or gameplay, and does nothing visible in-game on its own. It exists purely so other mods can build on top of it. You only ever install it because another mod lists it as a required dependency.
