mcimport

a fork of the original 'mcimport' for the MineClone2 subgame.

This fork of mcimport converts a Minecraft world into Minetest; specifically a MineClone2 subgame.

Notes

Compatible with Minecraft Worlds up to & including v1.12.2

This is a WIP; so the conversion list is continually being refined for more accurate conversions.

Coordinate Conversion from Minecraft to Minetest:

X = Approximately the same in both.
Y = Approximately -64 nodes in MCL2
Z = The number is approximately inverted.

Example:
Minecraft: -1457,4,-1632
Minetest-MineClone2: -1439,-60,1647

MineClone 2 Info:

The process is offline. Minecraft should not be running on the world that is to be converted. The output should be an empty folder, and no map.sqlite should be present in the empty folder.

The output is a world folder that is playable, permitted that you're using the MineClone2 sub-game. This is a WIP, so you may still encounter "Unknown" blocks in the Minetest world.

This mcimport fork was created to improve on the existing mcimport project, with one significant change: This form aims to create playable minetest worlds where stuff works:

chests can be used to put stuff in
doors open and close
simple mesecons circuits may work
furnaces work

Also, the assumption is that converted maps are for multiplayer use, and that the most important motivation for using this converter is to preserve previously custom built objects and buildings, but not meant to preserve the gameplay style and feel of minecraft. This project aims to never convert blocks to "Unknown" nodes and strives to leave a playable are that is friendly for users performing a one-time conversion.

some flowers are approximations
double plants may end up being single node blocks
until fixed, fences, walls & other items are likely broken

There are a large number of things that are just never going to be convertable, and so the following will likely never work and are therefore converted to air blocks. Entities are readily spawned by several mob mods in minetest, so conversion is likely not critical to users, and left out.

Usage:

You'll need to use a Linux system and have python installed. The easiest way to invoke the converter is to run the mcimport.sh script without any parameters. This takes you through a bunch of screens that you can use to select a world and configure a few settings.
