map_content.txt has
21 default:stone // FIXME: Lapis Lazuli

which I think is wrong. According to minecraft id lists:
21 Lapis Lazuli Ore (minecraft:lapis_ore)
22 Lapis Lazuli Block (minecraft:lapis_block)

This could be fixed by using: https://github.com/Napiophelios/LapisLazuli
Will send PR.

Hi,

I received some feedback recently regarding the possibility of this feature to simplify things for end users. That way users only need this one, the original mcimport script, but could choose between conversions.

As opposed to having one version of mcimport for MTG, and my slightly modified fork for use with MCL2: mcimport_for_MineClone2

But, before looking into how to modify the code for this, or attempting any PRs. I figured I'd ask; would y'all be open to having this feature?

Since 0.4.16 or so~~. It leaves unknown blocks on new MTG.

with this:
./mcimport.sh
./mcimport.sh: line 15: cd: /home/myuser/.minecraft/saves: No such file or directory

If I try to convert a particular Minecraft world with mcimport, I get a Segmentation Fault when I try to load it in minetest. Here's the error from minetest:

Said world can be found here, with the input and output of mcinput: https://send.firefox.com/download/1260c04323ecf744/#xyqM2fr2P49OY0bSx4KYLw

(it's a big file, so unfortunately I had to use Firefox Send. Download expires after 100 downloads or 7 days)

Unfortunately, Minetest isn't giving me much to work with to debug the problem.

I have discovered some other example Minecraft worlds that cause the same problem too if they are required.

As an enthusiastic newcomer to Minetest, I would love to bring some of my old worlds over from Minecraft. This script looks like what I'm after, but running it yields only the following error message and an exit status 1.

Home directory redacted; substituted with $HOME.

I tried it with the shell script first, but found that iterating while debugging was faster if I just ran the python script directly, and I was getting the same result either way.

I have tried it on four different worlds and get exactly the same result. One of the worlds is from MC 1.20.6 and another is from 1.12.2, so save version doesn't seem to be related. I've linked the example (from 1.19) below. (It's too large to attach apparently.)

The output folder does seem to contain some basic files, which I've attached in case it's useful.

Thank you for your time! I really appreciate it!

I can't seem to find the license. Would you add one, please? See http://choosealicense.com/ for more information.

Hi, I am trying to convert the "Witchcraft & Wizardry" Minecraft project (Light version first) from the following website.

https://gumroad.com/l/floomap
http://www.mediafire.com/file/xke143473zi4ytp/Witchcraft_and_Wizardry_-_Light.zip/file

Problem is I do get the following error during conversion:

$ python3 mcimport.py ../Witchcraft\ and\ Wizardry\ -\ Light/ ../witchcraft_and_wizardry/

I changed the logging a bit and added the output of the chunkpos, yslice, chunkpos in block.py line 92 to give some more context. Dunno if this is helpful ?

BTW: I have had to change the shebang to #!/bin/bash in your mcimport.py otherwise the resulting get_mods.sh would not run under Linux Mint / Debian.

What does the ":52:0" stand for? Any guidance what to do to improve coverage?

The README only mentions 'missing mode' which is a bit vague. How do I find out what mod I would need to install?

Im an idiot, I admit it.

but how do you run this thingy?

When starting the import, an exception occurs and creates an empty world:

python3 mcimport.py ... ...

    self.blocks = self.reverse_X_axis(section["Blocks"])
KeyError: 'Blocks'

Versions:
Minecraft: 1.15.2 (no mods)
Python: 3.6.9

On some worlds, the exception happens at the first line of the output. On other worlds, after a few correct output lines.
Here is a vanilla map, on which I have the exception at the first line (removed player data):
MTTest.zip

The mcimport.sh script is pretty simple and could be re-implemented in Python with perhaps Tkinter used for popup messages. OS specific operations such as checking if a directory exists can be done by using the Python os.path module.

This should make the code more portable and eliminate the need for users to have extra programs such as zenity and bash installed on their systems.

I keep seeing this message.
Tried to convert 10 saves. Some are very basic. So this is odd.
They all show this message and none of them are playable.
Am I doing something wrong? Are any other software required?
Very little documentation here.

Hello, every developer：

Can you develop a branch to convert maps of MCPE 1.2 or higher to Minetest maps?

If you can, I can't thank you enough.

Minetester · BingFengFSX（IFRFSX）.

What do you think about adding support for blocks provided by the MineFix modpack? Plus in the future work towards perfect Minecraft compatibility?

The conversion can take quite a bit of time. Right now the status is reported as

Saved xxxxx blocks

If the tool knows the size of the world, would it be possible to report it as

Saved xxxxx/yyyyy blocks

Ideally with some ETA. Unfortunately in blocks.py self.blocks in a generator, and hence it is a bit more involved to get the len(). Anyway, I'll give it a try.
