anvil2slime

This tool is experimental.

This tool converts Anvil worlds to the Slime region format. It loads all the Anvil regions into memory and saves it as a Slime world.

Usage

Basic usage

Assuming you have an Anvil world ready, run anvil2slime WORLD. A WORLD.slime will be generated in the base directory the world is in. You can change where the output goes by using the -o flag, i.e. anvil2slime -o test.slime WORLD.

Details

anvil2slime loads an Anvil world (with each region loading concurrently) and outputs a Slime region. This tool has been tested with a few worlds and should provide a perfect mapping of your Anvil worlds to Slime.

Currently, this tool relies on a fork of Tnze/go-mc's NBT library as it does not implement functionality that is required for this tool to work.

The reason why you'd want to use this tool over the Hypixel-provided slime-tools are many:

• slime-tools saves in Slime version 1 format and thus doesn't save entities. anvil2slime saves in Slime version 3 and does save entities.
• slime-tools doesn't work on anything other than 64-bit Windows without manually injecting native libraries into the JAR. anvil2slime uses only pure Go dependencies and is thus highly portable.

The one disadvantage is that anvil2slime tends to produce larger files, however this is an artifact of the compression library used.
