[Game] VoxeLibre (formerly known as MineClone2) [0.86]

[GamingAssociation39]

I'm working on a program that converts minecraft worlds to minetest worlds, using MineClone 2 as the target 'game'.

That already exists viewtopic.php?f=12&t=13709. It doesn't have MineClone2 as the target game, but I am sure it can be modified to such.

Well it doesn't have the correct names and only converts minecraft to minetest worlds. A Mineclone 2 world is different from a minetest world

It would need a lot of work so that you'll be able to do it on Windows and Linux and that it will work on all types of worlds big and small.

[YoukaiCountry]

Thanks for pointing out the python project for converting worlds!

My program (MC2MT) was something I wrote a couple years ago in C#, but was never quite happy with it since I couldn't convert lots of things properly to minetest well enough to do what I wanted. Now that MineClone2 is becoming a pretty serious minecraft replacement, I dusted off the old code and re-targeted it.

MC2MT is working well enough to convert most worlds in the old alpha format, and the new format, and it can convert even large worlds in a fairly reasonable amount of time using multi-threading (seems to take ~2 minutes per 100mb of minecraft world on my modest machine, which is pretty fast, I think), and it does work on Linux and Windows as it is.

I'm going to keep plugging away at it since it's already giving me good enough results to wander around reasonable facsimiles of the original worlds. I plan on open sourcing it (even though the code is pretty messy), and releasing it very soon, but the issues mentioned in my above post are really holding it back from truly functioning.

[azekill_DIABLO]

so your program is called MC2MC2

[InterVi]

how to install? lot a errors

[Wuzzy]

Yeah, there isn't a program to convert Minecraft worlds to MineClone 2 worlds. Yet.

The programs we have only convert to Minetest Game (the default subgame).

But I'm not a huge fan of C# because it's not really cross-platform and not Linux-friendly. Yes, there's Mono, but Mono really sucks, has a lot of bugs, it's not even a complete re-implementation of .NET. I can proudly say that my machine is a .NET- and Mono-free zone. :-)

Best long-term solution would be to re-write it in a different language which doesn't have said problems. Especially if the program code is of low quality anyway.

Heh, I like it.

I'm going to have to politely disagree with you about Mono. I'm primarily a Linux user, and I can say that Mono has been pretty solid for the past couple of years. It had a rocky start but it's made huge strides since then. It's also currently feature complete through C# version 6.0, with 7.0 in the works.

But regardless of technology disputes: a rewrite is probably in the future, but what I have is so tantalizingly close to spitting out usable Minecraft worlds in MineClone 2 that I'm at least going to get this working before I move on.

That said, the main issue holding me back is the dungeon generator placing things in the worlds as you move around. I haven't found a good way to turn them off without patching MineClone 2 or writing a seperate mod to do it. Am I overlooking something such as a way to stop dungeons generating by defining something in the world files? It'd be a huge help to this version and any future rewrite. Thanks!

Would it be easy to generate over the MC dungeons and they'll become MC2 dungeons?

[YoukaiCountry]

Would it be easy to generate over the MC dungeons and they'll become MC2 dungeons?

MC dungeons that already exist in the map being converted will carry over, but there is no way to tell MC2 that those are existing dungeons and to just use them as such, unfortunately. Even if that was the case the MC file format doesn't seem to store the location of where it generated dungeons as such, just the blocks it placed, so some kind of pattern recognition would need to be used.

I'm not really sure what the answer to this problem is yet, and I'm not 100% sure why it's spawning dungeons inside of blocks that should be marked as generated. The thought just occured to me that the problem could be that I am not setting the already-generated flag properly in the map data. Going to look into that later tonight.

Edit:
I think that is exactly what was going on. Great, I'm going to work on it a bit more and I'll make a thread with a release in the next few days.

Edit 2:
Nope, still seems to be generating dungeons :p

what about if you try to add this line to the minetest.conf https://github.com/minetest/minetest/bl ... mple#L1300

Gave it a shot, but it didn't seem to help. I'm not sure what is going on. I verified via a hex editor that the generated flag I am setting matches up with what the documentation says it should be, as well as what the other MC converter outputs.

Wuzzy, any chance you could weight in on why MC2 might be generating dungeons inside of blocks that have the generated flag already set / is there a definitive way to just turn off dungeon generation? Thanks a ton!

[Wuzzy]

The map generator of MineClone 2 generally produces wildly different results than Minecraft. And the map generators will very likely be incompatible for a long time. That does't mean it's impossible to import worlds, but if you import a part of a Minecraft world, it will of course fail to match up at the borders.

It is not possible to disable dungeons. The dungeons in MineClone 2 are generated by the mod “mcl_dungeons”. These are not Minetest's default dungeons, so mg_flags doesn't do anything.

I don't understand the problem with generating dungeons you have right now. Do you mean dungeons suddenly appears inside land which was already there? If so, you should post seed, coords and screenshot and post a bug report.

[shy401]

Hey Wuzzy,

I am just coming across this project, but so far, I love it. I think that this project has a lot of potential and I look forward to playing it more.

Here's a tip that you might like: if ever you need a reference for implementing some minecraft features, download the Mod Coder Pack (MCP) from http://www.modcoderpack.com/ . This pack allows you to view the unobfuscated source code of minecraft for free, assuming you have a copy of the game and the jdk installed. This should help if ever you need help implementing things like map generation and whatnot.

I hope my advice helps you out. Let me know what you think. :)

[Wuzzy]

No, thanks. One of the core principles of MineClone 2 development is to perform a strict clean room implementation of Minecraft.

[shy401]

Oh, sorry. I didn't realize that.

i thought i was up to date, since i get an update every day from the dayly ppa repository.
but apparently it only updates minetest_game :P
upgrading to 4.16 didn't work, so i uninstalled it and then installed it again, now it's 4.16 =(^.^)=

[dawgdoc]

If it is of any help, here is some of my experience with MCL2 subgame.


I created a world about a week ago with a copy of MineClone2 dated from about 1 August 2017. Last night I updated the subgame and mcl_supplemental, which is the only mod enabled for the world outside of its default elements. My version of minetest is the 0.4.16 from the ubuntu stable ppa. After 25 minutes of game play I stopped and saved the log, which was 1.6 Mb in size. There are several lines that are highly redundent. Instead of posting the full log I will clip most of them out, all but one each, and post the associated line counts. I actually believe the high count lines -- those about deprecated functions, are coming from the game engine because I see much the same when playing recently created worlds in MTG and Pixture. During the time in which this log was generated I mined stone, iron ore, and gold ore. The gold ore made the correct sound for being picked up, but did not appear in my inventory. (Could this be because I was using a stone pickaxe? GOing back to this world I was able to dig and pick up the gold, redstone, emerald, and diamond when mined with an iron pickaxe.) I smelted the iron ore into iron ingots. Likewise I cooked a couple of pieces of raw chicken. Also I crafted and placed a crafting table. I used the table to make planks, sticks, and stone pickaxes. Because the gold ore was not picked up I did not mine the red stone and emerald that was present at the final mining site. A zombie was present at the door of the mine hut before and after I was mining.

I created a new world with MineClone2 and mcl-supplemental current as of last night. The debub file was similar to that above. so far I have mined and harvested a few trees. Oh, did have a creeper explode nearby. Again I have made a crafting table, from which a furnace and stone tools have been created. I will post a few lines of the 4 Mb debug log from an hours play. I didn't count lines this time and will leave out that common to the other subgames.

During the time in which this log was generated I mined stone, iron ore, and gold ore. The gold ore made the correct sound for being picked up, but did not appear in my inventory. (Could this be because I was using a stone pickaxe?

In MineClone 2, drops are different: Although almost everything can be dug by hand, not everything yields its useful item without the correct tool. Gold ore needs at least an iron pickaxe. Some blocks even have different drops depending on which tool you used.
Use the in-game help to learn more about blocks, required tools and their drops. Hint: Craft yourself a lookup tool.
The block help entries are probably fine, but I think I need to update some of the basic help entries, for example that one about digging.

Also, I always like to hear general feedback about the help system.


Thanks a lot for reporting those warnings. Yes, I might have eliminated them earlier but thanks for reminding me. xD

[dawgdoc]

Looks like I will be making more pull requests tonight, deleting old worlds, and creating a new world. ;-]

[Wuzzy]

Hello. Today I want to release version 0.27.0! Nicknamed “The Mapgen Update”.

This giant update adds support for all mapgens, and the Nether and the End (incomplete).

Compability notes

• Finally all mapgens are officially supported!
• The End is currently a preview only. It is very incomplete and will definitely change completely
• Biomes (for all mapgens except v6) are incomplete and will definitely change. The worst which could happen is that there will be visible “borders” when you continue to explore the Overworld in future versions. That's all!
• Existing v6 worlds should be unaffected, continuing to use v6 should be safe.
• The End portal is a dummy and will be completely replaced later

How to build portals
How to build a Nether portal: Build an empty upright 4×5 obsidian frame, then light a fire on the frame.
How to build an End portal: Build an empty upright 4×5 frame made of blocks of quartz, then use an eye of ender on the frame.

The changes follow:

Mapgen:

• Add support for the remaining mapgens: v5, v7, valleys and fractal
• New biomes for these mapgens: Desert, red desert, mesa, glacier, icesheet, jungle, savannah, grasslands, deciduous forest, coniferous forest, roofed forest, taiga, mushroom land.
• Add the Nether (at ca. Y=-29000), may be subject to improvements
• Add the End (at ca. Y=-27000). VERY incomplete.
• Abandoned mineshafts: Add minecarts, cave spider spawners and cobwebs
• Dungeons: Widen the openings of lonely corners to allow entry
• Add unique flat variant of the Nether when using the flat mapgen

About the new mapgen features:

• v6 mapgen will be continued to be supported and improved, but like in Minetest Game, it doesn't generate all the blocks, trees or biomes which you can now find in the other mapgens
• Like the Overworld, the End has a very generous height limit (ca. 25000 blocks; at the top you will collide with an invisible “realm barrier”)
• The Nether has a height of exactly 128

Blocks:

• Nether Portal
• End Portal
• Lava in the Nether automatically turns into Nether Lava which has an increased flowing distance
• Realm Barrier: Internal block to separate the End from the void below the Overworld
• Dark oak sapling grows into a proper dark oak now (still not 100% complete, however)
• Fire is not destroyed by flowing liquids
• Kill hanging vines below a dug vine
• Beds explode in the Nether and the End if you try to sleep
• Ice doesn't turn into water in the Nether

Mobs:

• Spawn shulkers in the End
• Spawn all Nether mobs in the Nether
• Spawn zombie pigman in Nether portals in the Overworld

Other:

• New minecart model and texture
• Water buckets can't place water in the Nether, except in cauldrons
• Fire charges now act as general igniters (you can use them to open a Nether portal, too)
• Remove all Nether-related temporary crafting recipes, and some other
• Compass and clock are confused in the Nether and the End

Bugfixes

• Fix crash when clicking on invalid item in craftguide
• Furnace: Stop cooking if output is full
• Fix generated mob spawners sometimes have pig
• Fix annoyingly “sticky” black sky when flying into the void and return to the overworld
• Fix magma blocks hurting you when you are 2 blocks above
• Fix and weaken the broken mcl_tnt dependencies
• Support Creative Mode for minecarts

Maintenance

• Update doc and doc_items mods
• Use new Minetest settings API syntax for most mods
• Update tsm_railcorridors
• Fix a couple of console warnings
• Remove worldedit_gui error message. Worldedit_gui is now officially incompatible with MCL2; it's now up to the developers of worldedit_gui to add support

The Overworld (in the v7 mapgen)







The Overworld (in the valleys mapgen)



The End (WIP)



The Nether

[YoukaiCountry]

Really exciting update, great to see the Nether in.
This update also seems to solve the dungeons generating in my pre-generated maps somehow, which is great.

Something I noticed: I understand it's a work in progress so you may be aware, but The Nether scale shouldn't be 1:1 with the Overworld.
The (X Y dimension) Nether blocks count for 8 Overworld blocks, so a portal placed at 10, 25 in the Overworld would appear at 80, 200. It makes it a great way to travel long distances.

If you need screenshots or something else, I can provide them.
