[Apollounknowndev]

absolutely amazing that you're doing guides now!

[SirPankratz]

How would you set the y height for a structure?

[misode]

In 1.19 it's easy with the start_height field.

In 1.18.2 it's a bit tricky but it can be done by using the bastion_remnant structure feature type and adding an intermediate jigsaw piece to move the start. Bastion remnants always spawn at Y=33.

[ManosSef]

Will there be guides for other parts of data packs? (I mean, I won't need them, but it will be cool if they exist)

[misode]

Yes I have more guides planned, in the near future mostly focused on worldgen. Let me know if you have a specific suggestion though!

[ManosSef]

If you want, I could help with the guides for things other than worldgen, especially advancements. I love testing all kinds of different things with them and I have learned a lot.

[misode]

I'm open for PRs to contribute guides! I'll add some instructions on how to get development setup to the readme.

[AirplaneA220]

A suggestion I have is maybe how to add custom structures to the custom biomes(I mean this as like the feature placement) to kinda build off just adding new structures in the game

[xana43]

For some reason when I try this it always keeps saying "Unknown registry key in ResourceKey[minecraft:root / minecraft:worldgen/structure_feature]" I get that I need to register the structure, but how do I do that seeing as apparently that API is completely gone as of 1.18.2

[xana43]

NOTE: I'm trying to make structure generate using Fabric MC

[skerit]

I'd like to know too, getting the same error.

[misode]

If you're updating to 1.19, here is a tutorial mod for fabric: https://github.com/TelepathicGrunt/StructureTutorialMod/tree/1.19.0-Fabric-Jigsaw

[skerit]

Yup, I was still on 1.18 - I did not see the little version switcher in the top right of the article. It's working now.

[Danjhop4]

How do you add a structure that does not generate in the void in the end

[ghost]

Hi,

Brilliant work. I don't know if I would have succeeded with my plans without the things you've shared on your page.

I'd like to know if it's possible to make a structure generate in a grid, so that the structures are always an equal distance from each other. Do you know if this is possible? The 20w14infinite snapshot had it in the fleet dimension.

[misode]

You can do this by setting separation one less than spacing in the structure set.

[ghost]

I did that earlier, but it didn't work. I now retried just to be sure, and I can confirm that it didn't solve the problem. The structures are clearly placed unevenly.

Also I don't know what the "starting block" of the structure is (as in, the block that's used as the "pivot" when the structure is placed in different orientations) and what determines its coordinates inside a chunk. These certainly don't help.

[Gurkenkoenig]

Man. Just 6 months ago i found this site. I Was trying to make a village using jigsaw blocks, But i gave up. But maybe now that you write some guides i can try again. Idk how you feel about making some tutorials on utube. Thanks for your time.

[GentlemanRevvnar]

Are there any other variations beside
"terrain_adaptation": "beard_thin" ?

[misode]

Thanks for reminding me, I was supposed to list these options in the guide. For you can see the options in the generator.

[ThatRobin]

Im currently working on a structure, but each time it generates, it generates 1 block into the ground, is there a way to stop it from doing that? All of my setting match the tutorails exactly, im just using using my own structure

[misode]

If you're in 1.19 you can set "start_height": { "absolute": 1 }, if you're in 1.18.2 you just have to add an extra layer of structure voids at the bottom.

[Silabear]

Why hello there,

Is there any way to make these spawn in a nether-like dimension, since it seems to spawn on the roof for me. Thanks :D

[misode]

It's impossible right now to make a structure spawn on a surface that is not the very top surface of the world (cave or nether like dimension). If you notice both the bastion remnant and ancient city spawn at a height independent of the terrain.

[Silabear]

So essentially I can't?

[mbg206]

Where did you find this information? I am trying to figure out what each of the options for "terrain_adaptation" and "project_start_to_heightmap" do, but I can't seem to find any documentation online.

[misode]

Most of this comes from looking at the vanilla worldgen files, and from reading decompiled source code. I've just added the info for terrain_adaptation.

[mbg206]

What's the difference between "WORLD_SURFACE" and "WORLD_SURFACE_WG", and what exactly is "MOTION_BLOCKING" and "MOTION_BLOCKING_NO_LEAVES"?

[misode]

The different types are explained in a separate guide

[Lonemind]

How would one go about making half buried structures in 1.18.2?

[Lonemind]

Misode was kind enough to reply on his discord. For those looking here for answers the solution in 1.18.2 is to split your structure into two pieces, a top and a bottom and then link them with jigsaws.

Apparently, though, 1.19 has the "start_height" option which will make this easy with just a single structure.

[Gurkenkoenig]

would it be posible to make the tower guide but with a jigsawblock? i cant really get it to work, i am trying to look at other datapacks online that do stuff with jigsaw blocks but i cant figure it out.

[misode]

There's this very detailed guide for jigsaw structures by GentlemanRevvnar

[Gurkenkoenig]

Cheers man. I somehow didnt get an Email 11 days ago. I check it out when i am home.

[BluJayy728]

I've got structures generating in the world fine, but for some reason they are all sunk 1 block into the ground. Why is it doing this, and how do I fix it? I'm on 1.19 if it matters.

[Gurkenkoenig]

Is it allowed to link me your Pack? Did you use the wg generation step Method or the non wg thingy? I am at work so i cant check what the names are

[BluJayy728]

I'm using WORLD_SURFACE_WG. I'm thinking I might just need to put structure void under my structures.

[BluJayy728]

Yeah all I had to do was use structure voids under the structure. Thanks for trying to help though.

[TimmyChips]

What would be the best way to generate structures that use the underground_structures tag? Using WORLD_SURFACE_WG for project_start_to_heightmap doesn't seem to always generate the structures. Removing the heightmap makes it so structures will actually spawn, except sometimes when they spawn, they're by themselves and are not connected to any caves. There might not be any work around though, it might just be like dungeons, which a lot of times spawn not connected to anything.

[TimmyChips]

Ideally I would like to make structures that are on the sides of cave walls similarly to dungeons and amethyst geodes, and spawn closer to the bottom of the world.

[misode]

There's currently no way to get an underground structure to spawn like that unfortunately

[TimmyChips]

Ah gotcha, thank you for the response! I figured there wouldn't be a way to do it, but I figured I would ask. I guess you could do thin_beard to try to open it more, or a workaround would be to create several "cave carver" structures and use jigsaws to try to branch out.

[Luke652]

What's the size limit for a Structure now? I know that 1.18 had a limit of 7, but what does 1.19 have?

[misode]

It has the same jigsaw depth limit of 7. In terms of blocks there is a limit of 128 blocks out from the center.

[Alexey10240]

Will there be a tutorial on creating processor lists?

[Insane96]

There's anyway in 1.18.2 to prevent the structure from generating inside an area (E.g. 200 blocks from 0, 0)?

[misode]

Not really. You could pregen the world around 0 0 with a version of the data pack that doesn't have the structure if that works for you.

[TheeMrCheeky]

I set it to underground but still spawns ontop on the bedrock in nether ugh idk really trying to figure this out. ty in advance

[TheeMrCheeky]

how would I make a structure spawn in nether?

[TheeMrCheeky]

by this i mean they spawn but they spawn up on bedrock

[TheeMrCheeky]

I set it to underground but still spawns ontop on the bedrock in nether ugh

[fishBone000]

i guess it's related to the project_start_to_heightmap. Check vanilla nether structure files as examples.

[Alumopper]

just set "start_height" like this

"start_height": {
      "absolute": -70
    }

change the value of "absolute" to change the depth of your structures from the top.

[Youritch]

hi, how can I prevent my structure to turn (if the structure is not generate in the good angle it's break it) ??

[Aitbead]

I am copy pasting original minecraft vanilla villages and editing them to spawn in the Nether. I managed to do that, but I have some problems with the natural spawning of them. In the "name_datapack\data\minecraft\worldgen\structure" folder I can edit stuff like you mentioned above, but the villages either spawn on top of the nether (on the bedrock layer) or they spawn down within the nether, but only the city centers. Do you know a way to bypass both these problems?

[ThatHomelessGuy]

I'm in 1.19 and cannot for the life of me get any structures to spawn. My structure doesn't even show up under the locate command.

[vico93]

That's why i absolutely hate the vanilla standard about this (and worldgen in general as well). While misode did a awesome work documenting that i still can't understand well and would kill for someone to bring Pillar back to life, this time as an alternative specification for custom structure spawning.

[PansRB]

does someone know how do i make the structure and turn created structure into nbt thing?

[Insane96]

Structure blocks https://minecraft.fandom.com/wiki/Structure_Block

[stefann01]

This guy here explains.

[vico93]

Are custom structures like this ones generate in overworlds of custom world presets (in 1.20)?

[majster2nn]

So yeah the datapack is created one small issues: structures dont spawn and minecraft seem not to detect that they exist

[DaNitroNinja]

This is all of the code from the structures and worldgen folder in my datapack. The name space is impossible.

[DaNitroNinja]

Sorry, github on my computer is saying that the messages above didn't send, please can you confirm whether they have sent now?

[misode]

The folder of one of your files is incorrect. Move data/impossible/worldgen/jungle_structure/jungle_home.json to data/impossible/worldgen/structure/jungle_home.json.

And also replace the reference in the structure set to: "structure": "impossible:jungle_home",

[DaNitroNinja]

Thank you, minecraft now says it exists, but if i use '/locate' it will just give an error message saying "cannot find a structure of type impossible:jungle_home nearby.

[DaNitroNinja]

I managed to fix it!. I forgot to call the structure_set structure_set. That was stupid of me!

[DaNitroNinja]

For me if i try to use the datapack, it says that it fails validation, even on a new world.

[JjCraft909]

same

[ShdwDrgnVIIv2]

Could someone have a look at my pack and see why my structure_set files are giving me an error with the namespace? It would be much appreciated!

https://github.com/ShdwDrgnVIIv2/test_pack/tree/main/data

[JjCraft909]

I used this in my datapack and it no longer works after I added a second Structure. It shows only one error in the structure_set files: "Failed to resolve namespaced ID “sqol:undead_temple” in cache category “worldgen/configured_structure_feature”.datapack(4)". I am creating a 1.20 Datapack and would like to know what changed from 1.19 to 1.20 that causes this bug? idk how to send my code but if i did I would do so.

[codemdragon]

How do I add this to a specific dimension

[Julynx]

I'm making a "sinkhole" structure.

The "/locate structure" command autocompletes the name, but when I hit enter it just always says "Could not find a structure of type sinkhole:sinkhole nearby"

The "/place structure" command just says "Failed to place structure" every single time.

I want the sinkhole to be buried in the terrain, with only the top side open so that the hole is open from above.
