This pack adds an additional new structure to your Minecraft worlds - underworld labyrinths!

These sprawling maze structures are constructed from Blackstone variants, and they generate deep underneath the mountains in normal Mountains biomes. They're filled with mobs and treasure, some of which one would typically need to build a Nether Portal to find...

Each labyrinth structure is constructed from 13 smaller maze pieces, arranged in a diamond, like so:
X
|
X-X-X
| | |
X-X-X-X-X
| | |
X-X-X
|
X

There are 64 different maze pieces that the 13 can be chosen from when the labyrinth generates. This provides for treasure and mob variance, and ensures that no two labyrinths are the same.

Each maze piece contains exactly one chest, which holds exactly one item. There is:
•a 1 in 64 chance of a Block of Netherite
•a 1 in 32 chance of a Block of Diamond
•a 1 in 16 chance of a Block of Emerald
•a 1 in 8 chance of a Block of Gold
•a 1 in 4 chance of a Block of Iron
•a slightly better than 50/50 chance of a lump of Coal



There are, of course, more mobs than treasures. The labyrinth can be a grueling and hellish place, lit only by the impossible ambient light of Minecraft's depths...

Happy hunting!



Hint: Underworld Labyrinths use the structure type "minecraft:bastion_remnant", which otherwise can't be found in Overworld; hence, /locate minecraft:bastion_remnant while in Overworld will always find you an Underworld Labyrinth.

Is this compatible with Minecraft 1.19.2?
World Generation isn't That different, but I don't want anything funny happening.

Question: how did you get the maze to have air pockets? I'm working on a custom bastion, and no matter what I do, air gets filled in with stone. Idk if you'll see this, but thanks if you do!

Before you save your structure file, you'll want to replace all minecraft:air with mincraft:cave_air. The default air functions like structure void rather than like air when structures are generated at generation time, which I suspect is a feature rather than a bug (because otherwise having multiple air versions would serve no purpose).

I confused cave air with structure air, which only exists in bedrock! Thank you so much!

Error I received. Crash to Desktop heres the report. Looks to be a simple syntax issue with minecraft block ids.

I belive it may be in the nbt files somewhere. I verified it wasnt conflicting with any other datapacks I had since With my combined datapack it wasnt even generating at all. Thats on my end. But after seperating the too and using locate basiton_remnant, This error only occured when i loaded bastion remanants with this datapack enabled and all other modifciations to the mountain.json turned off in my other datapacks. So I think its a placement issue BUT it does generate the structure. I revisted the coords after disabling your datapack and my datapack did not cause a crash but the rest of the structure was in fact generated. So it must be a nbt file thats corrupted or something.

Hey, thanks very much for catching this, and especially for the log! I was able to locate the error and iron it out; I've uploaded a fixed version of the pack, if you'd like to download again.

Thanks again :)

Of course! Its a really intresting datapack and I want to use it. I feel though that not enough people who find these sort of bugs take the time to look thru the crash logs to figure it out and report it. Im just glad the report made it easy for you to update it!

Lol true. The log was helpful for sure - it helped me identify that at least one of the 64 maze pieces had a faulty jigsaw.

While I found it pretty early (in piece #5), I still had to check all 64 pieces in case I'd done it twice lol... but thats okay. I totally agree that more people should post logs like you did, but in all fairness, this community is much better than most :).
