WorldPainter support?

[Captain_Chaos]

Well this all sounds very encouraging. I think I can come up with something relatively simple, yet useful. I'll probably support v25 of the serialization format, the sqlite backend and the minecraft_game block set (insofar as they overlap with Minecraft), at least initially. I'll need people to test once I have something up and running. I don't know when that will be yet, but I'll keep you guys posted.

[TheReaperKing]

My students and I would be happy to test it!

[toby109tt]

I would love to test it!

[sfan5]

About required files you should be fine with only map.sqlite, world.mt and map_meta.txt (for disabling the default mapgen).

[Captain_Chaos]

What is the "ignore" block for? When should I be generating it instead of air blocks?

[Nore]

"ignore" is used for unloaded blocks or nodes. You should never generate it.

[Captain_Chaos]

That is nice and clear, thanks. I will refrain for now. ;)

[toby109tt]

That is nice and clear, thanks. I will refrain for now. ;)

Can you post updates on progress? I'm really curious in the process behind the scenes
It's the good opportunity to ask now :)

[Captain_Chaos]

"ignore" is used for unloaded blocks or nodes. You should never generate it.

Should it exist on disk? The reason I know about it is that I see it in a dumps of a test map I made with Minetest. Usually the only other nodes in the block are leaf or air nodes.

I'm curious how it is used, exactly, as there might be circumstances in which it would be useful for WorldPainter to generate them, for example perhaps around the edges of the generated area for objects which extrude outside the generated area.

[Nore]

Hmm, I am surprised that it may even exist on disk. You can try to do as you say, but beware that it may have strange consequences, so try to avoid it if possible.

[Captain_Chaos]

Hmm, I am surprised that it may even exist on disk. You can try to do as you say, but beware that it may have strange consequences, so try to avoid it if possible.

Maybe some day; it seems clear that initially I shouldn't bother with it. But if it's not supposed to exist on disk you might want to look into that, as I'm seeing it quite a lot. Let me know if you need details.

[Captain_Chaos]

Check out the buildbot script. That script and the 32-bit pendant download cross-compiled libraries for MinGW and compile the binary automatically.

What environment is that script made for? I'm trying to compile Minetest on Windows.

It says that it's for Windows (but apart from that I dunno sorry I can't help)

[Wayward_One]

It says that it's for Windows (but apart from that I dunno sorry I can't help)

Yes, it's for compiling Minetest for Windows, but that script is meant to be run on Linux.

[toby109tt]

How does that make any sense whatsoever?

[twoelk]

It is called "cross-compiling" and is done quite often or did you really think all them apps for Android where all programmed on smart phones ;-P

Quit often the target OS of an apllication doesn't even have a development environment so that it may need to be compiled on a different OS. Think off all the other devices and robots used in the industry or your smart toaster or whatever.

Compiling Minetest on a MS-Windows system seems to be a lot more difficult and resource demanding than on a Linux system. Therefore some executables for Windows or Android systems are cross compiled on Linux operating systems that seem to have easier access to all the libraries needed.

For example the Windows-Builds provided by sfan5 are built on Linux while those provided by Krock have been built on Windows-XP.

[Captain_Chaos]

So is anyone building Minetest on Windows? I've still not managed to do it. I actually get quite far with Bash on ubuntu on Windows 10, which compiles and links the executable, but it won't run due to missing libraries. Somewere, someone must be building Minetest on Windows, right?

[twoelk]

...
while those provided by Krock have been built on Windows-XP.

also you might want to wade through the Builds thread
Getting hold of people like Krock, Addi and maybe Jordach might be the best idea though

[Captain_Chaos]

Progress report:

[Captain_Chaos]

Alright, I have a first test version for people to try out and give me feedback. This is still in heavy development and nowhere near finished, so there will be bugs, missing functionality, usability problems, etc.

Also, if you are already a regular WorldPainter user, don't edit your existing worlds with this version. The regular version of WorldPainter will not be able to load any worlds which you have saved with this version!

First, you have to install Java, of the right number of bits for your OS if you are on Windows. You can download Java here. For 64-bit Windows pick the version with the name ending in -x64.exe.

Then, download and install WorldPainter. You'll need this snapshot; the plugin won't work on the regular version of WorldPainter:

64-bit Windows
32-bit Windows
Mac OS
UNIX/Linux

Install it, run it, and open the plugins folder from the Tools menu. Then, download the Minetest support plugin from here and place it in the plugins folder (do not extract it).

Restart WorldPainter and you should now be able to select Minetest as the map format on the New World screen (Ctrl+N or File-> New World...) or the Export screen (Ctrl+E or File->Export->Export as new Minecraft map...; obviously that text will have to change ;) ).

If you try it out let me know how you get on and what you think about it!

Caveats:

• WorldPainter is first and foremost, and will probably remain for the foreseeable future, a Minecraft map generator. The available block types and terrain types are geared towards Minecraft, and many of them won't be available on Minetest. This first version of the plugin tries to map blocks to minetest_game insofar it has the same, or very similar, blocks. Other blocks are left as is and will be rendered as unknown nodes in Minetest. In the future I'll probably add some way to customise the block mapping so that you can change it or add blocks from other mods.
• The Minetest format does not support the Nether or End dimensions, so if you load an existing WorldPainter world which has those dimensions you won't be able to select the Minetest format. If you delete those dimensions via Edit->Dimensions you should then be able to export it.
• There doesn't appear to be an easy way for WorldPainter to set the spawn point, and since WorldPainter maps tend to be higher (because they start at y=0 and have their water level at y=62 by default) Minetest will probably spawn you in the void outside the map, or in a cave.

Downloading the latest 64 bit appears to fix that for me. (Not directly from java main download page)

But WorldPainter (Windows 64bit) (EDIT: Win 10) crashes (with no error message) when starting up :/

(not sure if im doing the debugging thing right)

On Windows 7 64 bit I was able to install WorldPainter just fine but upon loading I see the splash screen but nothing else happens. I am using the 64 bit version of WorldPainter.

[Captain_Chaos]

Clearly I need to do some more work... ;) I'll have a new build out soon!

[Captain_Chaos]

OK, I uploaded a new build of WorldPainter. There was a dependency missing, but now it should work. The download links are still the same; for the links and instructions, see my previous post. Please try again and let me know how it goes!

Again: for Windows, make sure to install the right version of Java with respect to the number of bits. *-i586.exe for 32-bits; *-x64.exe for 64-bits.

[Badger]

Have updated java. Installed WorldPainter. But doesn't start. (Linux 64bit)

Have updated java. Installed WorldPainter. But doesn't start. (Linux 64bit)

And you have redownloaded it? That's odd, that error is exactly the one I fixed. I'll see if I can run it on Linux.

Edit: in fact I can tell from the timestamp in the error message that that is not the new version. Try downloading it again and reinstalling.

Another edit: it occurred to me that I didn't make clear I uploaded a new build of WorldPainter, not of the plugin. Sorry if I caused any confusion. Although it never hurts to download and install them both every time.

[Captain_Chaos]

I have another question for the developers: how is the lighting information stored in the map? It seems like the light propagates the same or similar in Minetest as it does in Minecraft, and I can already calculate the light for Minecraft so it would probably be easy to adapt, if I only knew how it was stored.
