Mod ZeroCore

ZeroCore, a utility library for Minecraft mods

ZeroCore is a Java Edition utility mod and development library created for other mod authors rather than for adding standalone content. It provides shared foundations for networking, GUI handling, BlockEntity synchronization, and complex multiblock machines. Its revised multiblock API is designed to work with multiple client mods while avoiding unnecessary performance penalties.

By centralizing these systems, ZeroCore helps technology mods build reliable machines, interfaces, and Minecraft server features with less duplicated code. It is especially useful as a dependency for industrial and reactor mods, remaining mostly invisible to players while improving compatibility and development efficiency. At BoxToPlay, we recommend it whenever another mod lists ZeroCore as a required library.
