HelloNBT

A powerful library for reading and writing Minecraft NBT data.

It supports:

• Supports reading and writing NBT (Named Binary Tag), in both big-endian (used by Minecraft Java Edition) and little-endian (used by Minecraft Bedrock Edition) formats.
• Supports reading and writing Anvil files and region files, including chunk data over 1MiB.
• Supports reading NBT compressed by GZip, Zlib, and LZ4.
• Supports reading and writing SNBT (Stringified Named Binary Tag).
• Supports NBTPath (a query language for NBT data).

To get started, check out the following tutorials:

• Quick Start (中文)
• Advanced Tutorial (中文)

We also provide detailed documentation for all APIs, which can be found here: HelloNBT Javadoc.

This library is used for the Hello! Minecraft Launcher. The API is currently unstable.
