Convert Minecraft maps to Minetest worlds

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 the required minetest mods are installed. If mods are missing, you will 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:

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. As such, there are numerous blocks that are not converted 1:1 from MC to MT. A good example is Lapis Lazuli. LL ore will be converted to plain stone, and LL blocks into blue wool, simply because there is no reasonable equivalent in MT that is an actually useful block and not something created purely to copy MC. This project also 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.

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. #

X = Approximately +16 nodes Y = Approximately -64 nodes Z = The number is approximately inverted. -16 nodes

A general [Example](https://github.com/minetest-tools/mcimport/issues/34) of converted coordinates:

Minecraft: 100, 1, -100 Minetest: 116, -63, 84

#
I took a quick look at that map's coordinates in minecraft. You'll need to teleport/fly to the following coordinates in your converted world.
