Kore

What Kore is

Kore is a Kotlin library for generating ordinary Minecraft datapacks from Kotlin code. It runs during the build and outputs vanilla datapack files, so the server does not need Kore or a Kore plugin. Typed game data helps catch typos in items, blocks, sounds, and commands at build time. The project lists 65+ typed commands, 50+ JSON resource types, and 80+ generated registries. Supported datapack features include commands, recipes, loot tables, advancements, and custom dimensions; Kotlin functions, loops, and variables can help generate repeated content. When the typed interface does not cover a command, function bodies can include raw command lines. Existing datapacks can be migrated gradually, with handwritten sections continuing alongside generated content. Kore is published as a Maven Central dependency, and the maker recommends a JDK and Kotlin IDE. An optional Gradle plugin can build, link, and reload a datapack when files are saved. A browser playground can generate a datapack ZIP. Kore currently does not provide mod bindings or generate resource pack assets such as textures and models.
