jMCX v0.2

Currently there aren't any sophisticated libraries to interact with Minecraft Anvil (more to come) files in Java (read, edit and write). And those that are around haven't been updated in a while or are directly integrated to projects like mcaselector by Querz.

With this library I want to provide an up to date and efficient (and also overengineered) way to interact with Anvil (more to come) files.

jMCX will in the near future be part of MinecraftOfflineOnlineConverter to enable UUID conversion down to entity level.

Supports

• Operations: Reading and writing (.mca from/to file)
• Compression types: LZIP, GZIP and NONE

WIP

• Operations: Editing
• Compression types: LZ4

Future

• Bedrock Region format
• GUI (BIG maybe!)

Usage

• Obviously download the jar
• Add it as a dependency to your project (dependent on your IDE)
• Take a look into the Main.java file.

Sources

• https://minecraft.wiki/w/Region_file_format
• Dependencies: jNBT
