Minecraft Education Edition World Loading Error #779

lanceingle · 2017-03-23T06:22:34Z

I'm trying to use MCEdit to load a world that was created with the education edition of Minecraft. My wife has been tasked with letting kids make things in Minecraft and then we export them to STL files for a 3d printer for her work.

I'm trying to follow the instructions on Mineways to convert the newer version of the world (LevelDB?) to the older PC version that Mineways can understand to finish the STL export process.

I found a comment in the issues where a dev got 1.0 to at least load. I can't seem to get that to work with the latest pull from master.

Here is a link to the .mcworld file (it's just a zip) I'm trying to load.

I guess I'm the dev you're talking about...

You may lack some .so files to use properly the current PE support. These files are included in the .app, but since I'm not an OSX expert, I'm not sure which ones you have to extract. (1)

The --debug-pe CLI option create a specific log file to see how the PE support guts are working. You can use it, of course, but be aware it can create a gigantic file.

Also, it is highly recommended to use the binary NBT support.
To get it you have two options:

Look in the MCEdit .app for OSX; search for _nbt.so and copy it to your MCEdit source install pymclevel directory.
Install Cython 0.21.2 and run python setup.py build_ext --inplace from your MCEdit source directory.

Now, lets talk about the PE support itself 😄

The current support is not exactly working. You may be able to open PE worlds with, but no guaranty about what happens (as you know). It is handled by a binary file: leveldb_mcpe.so in pymclevel subdirectory.

We're working on a new version of this support. You shall already have in your source installation: libleveldb.dylib in pymclevel subdirectory.
It is possible to use this new support, but just remember it's under development, so backup your worlds (at least)...

To use it:

Create the new_features.def file alongside mcedit.py.
Put these lines in the file:

loadNBTCompoundList
newPocketSupport
levelDBPy

Run MCEdit using python mcedit.py --new-features.

You shall be able to open the world.
Remember that PE and PC versions does not contain exactly the same blocks, so putting stuff from one version into another one may not work, and even crash MCEdit...

Please, keep in mind some people reported memory issues when trying to work with large selections.

P.S.: I've looked to Mineways documentation, and tested the MCEdit part with your world. All went fine 😄

P.S. 2: You're the first one outside the dev team who may test this new PE support on OSX, AFAIK. Any feedback is welcome 😉

(1) You will find two .so files for the NBT and PE support in two different places in the .app.
_nbt.so will be found in Contents/Resources/pymclevel/ and Contents/Resources/lib/python2.7/lib-dynload/pymclevel/; leveldb_mcpe.so in Contents/Resources/pymclevel/ and Contents/Resources/lib/python2.7/lib-dynload/.

@LaChal Yep, I was referring to you. Thanks for taking a look at this.

Quick Question: Since you went through the process defined on the Mineways docs. Is it possible to automate the conversion without the GUI. I skimmed the mcedit source and thought that it might be possible but it was getting late last night.

Your "new-features" flag did the trick. MCEdit successfully loaded my world! I was able to convert the world back to the PC version. I did hit a snag though. There was a file_dialog bug that was pretty simple to patch. The details are below.

Due to my very limited feature requirements I'm not sure I have a ton of feedback. But it does work and thank you for this. Saved me from having to read up on LevelDB. I was so excited last night when I stumbled upon your post saying you were able to read 1.0 PE. I figured once it was read and loaded that translating these simple worlds the kids would make back to classic wouldn't be that much harder.

Let me know what you think it's possible to automate this workflow.

Crash / Fix
Workflow is as follows.

Open world
Select All
Copy
Create New World <---- Crashes here
Paste
Save as PC version

Crash
It happens when I click create with the file dialog modal open. I tried it twice to no avail. Also tried with a path that has no spaces as well.
Path that I'm attempting to save to: "/Users/lingle/Desktop/untitled\ folder/"

Fix. I didn't test it very thorough but here is what I did. Seems to work.

     def get_pathname(self):
-        return path
+        name = self.filename
+        if name:
+            return os.path.join(self.directory, name)
+        else:
+            return None

A method was not correctly written in the internal file dialogs which prevented to 'save as' files and worlds. This issue has been reported in #779, and the fix is mostly lanceingle's one. Thanks to him 😄

Thanks for the fix 😄

It has been implemented!

The nes PE support is now the default one, since it's the only one which permit PE 1+ worlds to be edited. The lines: ``` loadNBTCompoundList newPocketSupport levelDBPy ``` Can be removed from the `new_features.def` file, and the CLI switch `--new-features` is no more needed. (Referencing #805, #803, #801, #779, #676, #671.)
