World Generation General

[sly forge]

in the process of getting help with arg 3 of the lerp

[limber jewel]

nah, molang doesn't have ranges (i wish it did)

here's a basic example:

v.current_blend = 1;
v.blend_factor = 1;
v.blend_dist = 8;

loop(v.blend_dist, {
    v.current_blend = math.max(0, v.current_blend - (1 / v.blend_dist));

    !q.has_biome_tag('foo', v.worldx + v.blend_dist, 100, v.worldz)
    || !q.has_biome_tag('foo', v.worldx - v.blend_dist, 100, v.worldz)
    || !q.has_biome_tag('foo', v.worldx, 100, v.worldz + v.blend_dist)
    || !q.has_biome_tag('foo', v.worldx, 100, v.worldz - v.blend_dist)
    || !q.has_biome_tag('foo', v.worldx + v.blend_dist, 100, v.worldz + v.blend_dist)
    || !q.has_biome_tag('foo', v.worldx - v.blend_dist, 100, v.worldz - v.blend_dist)
    || !q.has_biome_tag('foo', v.worldx + v.blend_dist, 100, v.worldz - v.blend_dist)
    || !q.has_biome_tag('foo', v.worldx - v.blend_dist, 100, v.worldz + v.blend_dist) ? {
        v.blend_factor = v.current_blend;
    };

    v.blend_dist = v.blend_dist - 1;
});

it searches for the nearest non-matching biome and sets blend_factor based on its distance

[sly forge]

breh you literally just said itd work 😭

[limber jewel]

i thought you meant a range, not an actual syntax

[sly forge]

yes, 1..8

that is a range

[limber jewel]

me when i write too much rust

[sly forge]

also two of those variables appear to be doing literally nothing

[limber jewel]

you'd supply blend_factor as the last arg in math.lerp

[sly forge]

so

as i said

kinda useless

because its not 1/8

its 1 TO 8 / 8

[limber jewel]

have you tried it? it would blend the terrain at the edges

[limber jewel]

seems to work just fine (blend distance is set to 16, dirt represents custom mountain feature, stone is original vanilla terrain on a custom biome)

for reference, here's how it looks like without blending

v.current_blend = 1;
v.blend_factor = 1;
v.blend_dist = 16;

loop(v.blend_dist, {
    v.current_blend = math.max(0, v.current_blend - (1 / v.blend_dist));

    !q.has_biome_tag('hills', v.worldx + v.blend_dist, 100, v.worldz)
    || !q.has_biome_tag('hills', v.worldx - v.blend_dist, 100, v.worldz)
    || !q.has_biome_tag('hills', v.worldx, 100, v.worldz + v.blend_dist)
    || !q.has_biome_tag('hills', v.worldx, 100, v.worldz - v.blend_dist)
    || !q.has_biome_tag('hills', v.worldx + v.blend_dist, 100, v.worldz + v.blend_dist)
    || !q.has_biome_tag('hills', v.worldx - v.blend_dist, 100, v.worldz - v.blend_dist)
    || !q.has_biome_tag('hills', v.worldx + v.blend_dist, 100, v.worldz - v.blend_dist)
    || !q.has_biome_tag('hills', v.worldx - v.blend_dist, 100, v.worldz + v.blend_dist) ? {
        v.blend_factor = v.current_blend;
    };

    v.blend_dist = v.blend_dist - 1;
});

v.height = 48 * ((q.noise(v.worldx / 40, v.worldz / 40) + 1) / 2);
v.height = v.blend_factor == 1
    ? v.height
    : math.lerp(q.heightmap(v.worldx, v.worldz) - 64, v.height, v.blend_factor);

return v.height;

heightmap has to be offset since my feature rule starts Y level at 64

[austere nymph]

So what are the basics of structure generation I want to put a structure in my addon but I don't know how it works

[hard cipher]

There are two ways jigsaw and features

[austere nymph]

I'll go with features

[hard cipher]

https://wiki.bedrock.dev/world-generation/world-generation-intro

[vagrant ruin]

how would i make a feature that adjusts itself to the terrain shape?

[hard cipher]

I don't think it's exactly possible.

[vagrant ruin]

dang that's annoying

[hard cipher]

It depends on what you mean by "adapt."

If it involves changing the terrain, I'm not entirely sure, but if it involves generating the feature based on the terrain, then yes.

[limber jewel]

adjust as in "placed exactly above the highest block on the terrain"? similar to how trees and vegetation are placed?

[modest trench]

I suspect the answer is no, but is there a way to make natural caves stop spawning so I could use custom spawns of my own? I know you could create ore spawns that swap "air" for a selected block but I am wondering if there isn't a better, more elegant way.

[limber jewel]

caves are part of the initial base terrain gen pass (before biomes and features are placed), so sadly no

[modest trench]

I suspected as much, thank you

[subtle plinth]

modifying villages works

jigsaws in roads of villages seem to be sunk into the road in comparison to java where they sit on top

same thing applies to the jigsaws placing decorations

got the snowy shepherds house back in and the reference to the vanilla village/common/sheep pool went swimmily

[vagrant ruin]

no, I mean "project itself onto the terrain" kind of like how posdzol patches generate

[vagrant ruin]

yes, generating a feature based on the terrain (view above message)

[vale cliff]

Wow finally

[vale cliff]

How did you do that

[marsh ferry]

Does anyone know how to completely eliminate these generation errors? I literally have all my biomes in the air

[limber jewel]

there are a bunch of ways to do that, but the simplest would be to use vegetation_patch_feature which, contrary to its name, can place any blocks and not just vegetation blocks

[gentle raven]

anyone have a example of any biome?

so thanks

[subtle plinth]

so it's called sculk_patch_feature_ancient_city on bedrock and sculk_patch_ancient_city on java

got the shepherds house mostly working

the sheep jigsaw is broken because i forgot to set its final state

other structures fixed

time to tweak some other things

[upbeat barn]

Whats supposed to happen vs what happened?

Whats your feature rule?

[subtle plinth]

They doesn’t even register in the game, /place feature has got them in the list

[subtle plinth]

I’m not sure if they have one

[dense quail]

Wdym they dont register, but they appear in the list?

[subtle plinth]

they don't appear in the list

No content log errors they just straight up don't exist it seesm

I'll try registering a feature rule for them

[subtle plinth]

So I got it working but this pillar is extending upwards. Is it possible to make it go down?

[upbeat barn]

Get rid of step size and grid offset. Other than that, that should have made it go down.

[subtle plinth]

Ok I’ll try that when I get home

[subtle plinth]

now it goes up and down from where I was standing

I'm at the same level as where i was when I placed it

[upbeat barn]

Are you doing /place? That might have different placement thatn feature rule

[subtle plinth]

yeah

I am

ill try the featurerule

it tells me that I can't place the featurerule at that location

it placed 37 blocks above where i /placed it

[upbeat barn]

By that I mean natural feature rule not command.

[subtle plinth]

It doesn't generate naturally

it's not supposed to

this is something that only feature_pool_element should ever be placing rn

I'm just using /place rn

[subtle plinth]

feature pool element doesn't work with it

[subtle plinth]

Im gonna decrease iterations to 64 to see if that fixes it

well now it works

thats good

[dull pumice]

Someone have a tutorial on how to do flat biomes or something like this?

or like this?

[dull pumice]

a plain generation i want to know how to do it could someone explain me? 👀

[marsh ferry]

I can, let's talk privately

[subtle plinth]

I think feature_pool_element might be bugged

some of the jigsaws are not placing features like they are supposed to

/place is placing them fine

[jaunty osprey]

so i heard that people are starting to make perlin noise in scripting for the world gen...

[limber jewel]

i mean, there are already existing libraries for various kinds of noise in js

[sly forge]

has anyone tried to place structure voids with features?

[sly forge]

anyone?

[ornate tulip]

Hi! I'm trying to replace vanilla Oak trees with 6 custom .mcstructure trees. I've set up a weighted_random_feature and tried to override minecraft:oak_tree_feature, but it's not working—vanilla trees still spawn and mine don't.

[modest trench]

check out PavelDobCZ23's No Trees mod, it should put you on the right path

[sly forge]

vanilla tree features themselves were moved to legacy and are no longer modifiable

modify the vanilla feature rules to place your custom tree structure instead

[subtle plinth]

Placing a data mode structure block in a custom jigsaw structure doesn’t actually place the data mode block but it doesn’t do anything.

[uncut mauve]

i wanted to know if is possible to change the terrain generation using addons in the new version 26.20.26?

?

[half burrow]

Does anyone currently have a good way around the glitch where structures get cut off when 48x

[hard cipher]

It depends.

[subtle plinth]

using jigsaws or command blocks

[dull pumice]

Guys i need your help qwq

i dont know how to create paths for cities correctly.

in the next cases in "name" and "target"

case 1: straight street
case 2: curve street
case 3: cross street

because i see sometimes the cross street connects with other cross street or curve street with another curve street

https://tenor.com/view/business-cat-working-cat-boss-angry-gif-13655998

i read you guys qwq

[marble pagoda]

anyone know if its possible to prevent different jigsaws from the same addon from spawning on top of each other? my salt, separation and spacing are all different but for some reason it REALLY likes to spawn 2 structures of all places right next to each other 😭

[subtle plinth]

They need to be in the same set, otherwise no not really

[marble pagoda]

oh dang

[subtle plinth]

feature pool element is really buggy in naturally generated structures. All of those are supposed to be dirt but a lot failed to generate.

the first house failed to spawn foundations at all but the same house and the farm next to it both spawned their foundations fine for some reason

[marble pagoda]

do entities just randomly decide not to spawn in jigsaw structures? for the same structure sometimes it doesnt spawn any entity inside of it. mobspawning is on and is not peaceful difficulty. it's so dumb how inconsistent ts is 😭

[subtle plinth]

yeah sometimes some of my structures fail to generate mobs but it only happens on certain jigsaw structures of mine and very rarely. Like 1/50th of them are missing their mobs.

[marble pagoda]

the worst part is how do u even make a bug report for this becoz its so inconsistently not reproducable

[vale cliff]

How to make something like this spawn naturally , can we make like this? If yes can anyone tell how

[subtle plinth]

this is what placing a structure with /place looks like if the structure can only overwrite non air blocks lol

[uncut mauve]

i wanted to know if is possible to change the terrain generation using addons in the new version 26.20.26?

?

[fickle elm]

idk if anyone knows this but you can put fog levels in the negative and it puts a tint on your screen, its fire if you want more biome atmosphere

[limber jewel]

has anyone played around with the new noise features on the latest preview?

-# i can't check yet since my windows installation broke :c

[strong tendon]

I haven’t worked with jigsaws yet, but is it possible to split a large structure into pieces and generate it using jigsaws in a way that ensures each piece spawns next to the others? From the documentation, it looks like jigsaws don’t guarantee correct placement or even that all pieces will generate.

[royal bison]

Hey! is there a way to stop vines generating on my jigsaw structure? I tried all steps and isnt working

[fickle elm]

you could put command blocks in it and make them run a function that gets rid of vines that are nearby

[royal bison]

thats not optimized

[subtle plinth]

I don’t think so

[subtle plinth]

Yeah it is, template pools are mostly meant for randomization but you can also just put only one valid option in the template pool and it’ll work just fine.

[strong tendon]

Thank you! What if 1 structure fails, can I cancel the whole jigsaw?

[subtle plinth]

Nope

[strong tendon]

hmm interesting, so its possible that it'll miss some parts. anyways, thanks for your response. I'll try to read more in the docs

edit: oh wait I got it working now and I think I'm wrong nvm

[velvet spade]

weird tree using a tree feature.

[thick sandal]

is there a way to make partial biome replacements more like smooth?

  }
}

very basic stuff, experimenting for now

[upbeat barn]

Up the noise_frequency_scale. In the MS docs example they did 25

Can also lower the amount.

[thick sandal]

I mean it still generates with those ugly chunk borders

[upbeat barn]

Never experienced that before. The chunk borders, is it the plains biome or a different biome?

[thick sandal]

how can I now for sure? Idk
But there's like those random squares

[strong tendon]

Are feature rules placed after the jigsaws?

[upbeat barn]

Theres probably like a bajillion f3 biome detector on mcpedl likely.

[upbeat barn]

Yes!

That was a PITA when it wasnt back during experimental 🥴

[subtle plinth]

depends on the step that the structure and the feature rule are placed on

[uncut mauve]

I wanted to know if using minecraft:noise_gradient and minecraft:surface_builder that were added in 25.20.23 I could change the way the terrain is generate

[limber jewel]

umm, the only way that can happen is if the chunk gets stored in disk, which means you're not recreating the world after every biome/feature file change (which is something i recommend doing)

[limber jewel]

does anyone have ideas on how to decrease the performance overhead of Dimension.placeFeatureRule()?

actually probably not the best question to ask here

[strong tendon]

Is there a way to disable jigsaw random rotation

[upbeat barn]

No.

[vale cliff]

Does anyone know why these come

[exotic plank]

is there any tutorial to convert a structure into a jigsaw structure (i dont really get/need the jigsaw part its just 1 whole structure) since i need it to to be locatable using /locate

[upbeat barn]

Just have the start piece be your only structure then.

[exotic plank]

any way to force it to generate on flat ground? the structure has an offset of -10

[upbeat barn]

Your terrain adaptation seems to be the cause

[exotic plank]

i thought i need to use bury as the structure needds to be buried by -10, is it not that?

[upbeat barn]

No. You just need to add the offset. Terrain adaptation changes the terrain around it.

[exotic plank]

ah alright, what do you recommend i set it to?

"beard_thin"?

[upbeat barn]

None.

[exotic plank]

thanks, ill try it out

[surreal knoll]

So I'm trying to use jigsaw structures to spawn in structures larger than 48x48 (by splitting them into smaller parts and connecting them with jigsaws.

However I run into the issue that some of the structures crash my game during world gen or when manually placing them with the the /place jigsaw command.
For context, before the split the structures were at most 64x64x64 in size, after the split each jigsaw structure is at most 32x64x32 in size. I have one "base corner structure" that loads its neighbors, and one of those neighbors load the last corner. So the jigsaws never run deeper than 2 iterations.

Loading the structure pieces manually with the /structure command causes no crashes whatsoever, and the /place jigsaw command sometimes works and sometimes crashes me (sometimes a structure can work and sometimes the same structure crashes my game).

Are there any known problems that might cause this kind of behavior?

[half burrow]

Anyone know of a way to give a jigsaw block the ability to have several targets

So for example instead of it generating a hallway it generates a dungeon room

or know how to do it specially within the code?

[subtle plinth]

Just put multiple things in the template pool it is targeting

[half burrow]

I just realized, thank you so much! Hopefully I’m on the right track

[half burrow]

If I don’t choose a target name will it choose randomly based off of whatever’s in the template pools file?

[subtle plinth]

No

You have to set a target name which has to match the name of the jigsaw block or blocks if you have multiple that you want to be connectable to.

[half burrow]

I’m a bit confused,

I have a starting point which targets the pool hallways, and in that same jigsaw it targets jigsaws with the name hallways. I then have a hallway in which I specify the name.

All of this works and connects, however i’m getting lost here: Say I set both of the hallways jigsaw to have the target name hallways, it will generate the hallway jigsaw forever. How do I make it so that it can also for example generate a treasure room instead of just another hallway?

sorry for all the questions, but once this is figured out this will set me up for understanding the rest

I’m going to test something rq and see if it works

[subtle plinth]

In all the hallways you can just set the name field of their jigsaws to id:hallway and the target name of the jigsaw spawning them to id:hallway. The parent jigsaw will go to the target pool (template pool) and look for jigsaws with the name field matching its target name and pick one at random.

[half burrow]

Gotcha, I figured it out thanks to you

It’s confusing because it kind of makes you think a bit differently

[wooden topaz]

i have a geode feature and custom buds, but how do i make them rotateable based on where they we're placed

[half burrow]

One last question for you, do jigsaws need to be in 16x16 chunks like structures do?

As in where the structures can get bugged if too big and cut off

[subtle plinth]

Nah they can be 64x64 for each structure piece. The entire structure can be up to 256 blocks across as diameter.

[half burrow]

Wow, that’s sick

[half burrow]

Could you technically make a starting pool structure and have it be 64x64 and just generate that alone?

[subtle plinth]

Yeah

[half burrow]

Now i’m super excited lol

thank you

[subtle plinth]

Np

[vale cliff]

I tried to spawn a jigsaw structure by using commands but it says the structure has spawned but it's not spawning and if i try to locate and tp to the structure is not there what r the reasons this will happen

[fickle elm]

i wish they added a "block_blacklist" feature in the structure template feature

it would be so much easier to blacklist 1 block over having to whitelist every other block in the biome but that block

[half burrow]

Do you know how to make the structures rotate?

[subtle plinth]

Vertical jigsaws can randomly rotate structures

[modest trench]

wow!

[subtle plinth]

Yeah, they can be massive

[modest trench]

@fickle elm I've had an idea of doing a mining village inside a massive geode_feature via jigsaw and if geodes weren't so damned hard to get working on bedrock I would totally do that.

[half burrow]

Is there a way to have it be random in the code, it seems to face one way most of the time

[subtle plinth]

Nope

Well

In the structure you can put multiple connecting jigsaws and it’ll randomly pick one

To connect to

[half burrow]

I have a bone structure within 64x

[subtle plinth]

You can just control pick block the jigsaw block being used to connect to other pieces and place it around the structure and when the generating jigsaw picks that piece it’ll target one of the jigsaws at random

[subtle plinth]

How is it supposed to be rotated

Horizontal jigsaws can’t rotate pieces around

[half burrow]

North south east and west, it seems to be doing it

I have it vertical

[subtle plinth]

Only vertical ones can do that around the y axis

[subtle plinth]

The jigsaw?

[half burrow]

yeah

[subtle plinth]

Then it should randomly rotate unless the toggle in the ui is on

[half burrow]

gotcha

[subtle plinth]

Joint type should be togged off for random rotation

[half burrow]

Also curious, for dungeons do people limit certain structures to certain sizes to make them generate fully properly? I’ve noticed with my dungeon test they crash into eachother (of course not though though)

[subtle plinth]

If it’s on the line on the back side of the block will always match the line on the side of the jigsaw block placing it

[subtle plinth]

Yeah

But jigsaws are programmed where the piece bounding boxes can never overlap each other

You will never find a tunnel cutting over another one

[half burrow]

Interesting

Here’s a question then, can jigsaw structures hit into and overtake other structures

[subtle plinth]

Yes

[half burrow]

So have a very unique salt value

?

[subtle plinth]

Pillager outposts and villages in bedrock can show this in bedrock

[subtle plinth]

Salt can help but it doesn’t always solve it

[half burrow]

yeah

still cool

As long as it doesn’t override the end portal

[subtle plinth]

Salt is only useful really if the seperation and spacing values are the same as another structure set

[subtle plinth]

You can put a protected blocks processor in the processor being applied to the structure to prevent end portals from being overwritten

“Processor_type”: “Minecraft:protected_blocks”, “value”: “not_feature_replaceable” should work

[half burrow]

Gotcha

I love jigsaws so much

[subtle plinth]

Ye they cool

[half burrow]

it’s just that people really did not do a great job of explaining the actual placement and values of the jigsaws and how the processors work

The code didn’t make sense until that was done

[subtle plinth]

They will get even better when we get more block tags and processor types

[subtle plinth]

Yeah processors are really complicated

[half burrow]

not the processors getting an actual dungeon style thing to generate

or. even a structure itself

There is no great explanation for the actual connecting and values

just the code

[subtle plinth]

Yeah, the actual jigsaw blocks themselves are hard to explain because they are kinda 3 types of jigsaws in the same block

[half burrow]

O, would you happen to know if you can change the loot in a chest with processors?

[half burrow]

yes that itself confused me a lot lol

[subtle plinth]

Code neon on YouTube did a good job explaining them

[subtle plinth]

Yeah, on wiki.bedrock.dev there is a example

I’ll get a link rq

[half burrow]

Thanks!

[subtle plinth]

https://wiki.bedrock.dev/loot/randomized-structure-loot#jigsaw-processors

[half burrow]

Here’s a deeper question though, what about changing loot for specific chests in a jigsaw structure?

[subtle plinth]

Not really possible for a specific chest

[half burrow]

Dang

[subtle plinth]

A processor will apply loot to every chest in the structure piece that processes is applied to

[half burrow]

Can’t I use append loot in processors? instead of nbt studio?

[subtle plinth]

You can use a nbt editor to apply loot to chests

[subtle plinth]

Yeah

Trail ruins use append loot on sus blocks and I did it with the chests on that wiki page

[half burrow]

I know a great way to fix my chest problem for that then, simply make the structures several different ones to make it unique

[subtle plinth]

Yeah

[half burrow]

yeah this is going to be sick

Just wish we could specify chests somehow using the append loot block entity modifier. That would make for an awesome feature

[subtle plinth]

Some of my structures I just have a jigsaw template pool placing chests so that I only have a chest in the structure file and don’t have to make a processor to do it

[half burrow]

Also something sick would be the ability to replace all air inside of a structure block space with structure voids in the structure block interface

[subtle plinth]

Yeah

[subtle plinth]

/fill can do that

[half burrow]

for big ones you have to do it several times, a simple button would be sick

[subtle plinth]

/fill ~~~ ~~~ structure_void replace air

[subtle plinth]

Yeah

[half burrow]

especially for 64x bone structures lol

seriously though thank you so much for all your help, i’ve got a solid grasp now. One last question to end it off, is the max depth limit 20?

[subtle plinth]

Yeah

Trial chambers needed it to be 20 so they upped it. Ancient cities only use 7 interestingly enough. 7 is what it was before 1.21

[half burrow]

There’s no way ancient cities need only 7

they probably have several starting jigsaws

if that’s even a thing, kind of wanted to test that

[subtle plinth]

They actually do

Look at mcasset.cloud

Villages use 6 for reference

I think bastions do as well

[half burrow]

since when did we have access to the full minecraft files lol

i’ve been looking for these

[subtle plinth]

https://discord.com/channels/523663022053392405/1485453695532531742

[subtle plinth]

It’s the Java ones

It’s just that ancient cities are identical between Java and bedrock

[half burrow]

ah

[subtle plinth]

I found that out when recreating ancient cities from scratch on bedrock

[half burrow]

I think it makes sense now

They have several starting points coming off of the main ancient city, and they each have their own max depth

[subtle plinth]

Yeah

[half burrow]

what confuses me is how solid they made the generation to get it to be so perfect

or rather not collide at all

[subtle plinth]

https://youtu.be/VNaGXvpE0Nw?si=KAIkHKBALuM1X0Q4 code neon has a good video about jigsaws here

Provided he uses the Java file format

The function of jigsaws is the exact same between bedrock and Java

[half burrow]

Also here’s an interesting question, can you make 3 structures always spawn in. Like for example a docking station, a laboratory, an archive.

I need 3 specific structures to spawn but am ok with the rest being random for one of my jigsaw structures, is this possible?

[half burrow]

that’s good, i’ll be watching that for sure

[subtle plinth]

Not really

I tried but it didn’t work well

Only the starting piece is guaranteed to spawn

[half burrow]

That’s kind of frustrating

You can technically garuntee a spawn but the path to it would also have to be garunteed

[subtle plinth]

Yeah

Selection priority can help but I found it’s not 100%

[half burrow]

How does that stuff even work lol

i’ve been so lost with it

Just left it alone

[subtle plinth]

https://discord.com/channels/523663022053392405/1459006306915581984 I tried making custom strongholds here

[subtle plinth]

Selection priority is if two jigsaws are trying to place a structure in the same spot the one with higher selection priority wins

If they have the same priority then it’s random

[half burrow]

But isn’t it true that if you name 2 things the same they go by the weight in the pool list?

[subtle plinth]

Placement priority is if there are more then one jigsaw that are valid to connect to in the structure file whatever one has the highest placement priority will be used unless it causes the structure to placed in a invalid position in which the jigsaw block will pick another one

[subtle plinth]

Yes

Selection priority is more having to do with the generation order

In that YouTube video I sent code neon explains it

[half burrow]

Alright

[subtle plinth]

I’m bad at explain those two fields because they are very niche

I very rarely ever use them

[half burrow]

Also is 64x really the hard limit on jigsaw single structures? kind of curious to see if it expands

[half burrow]

I will not be unless i’m forced lol

[subtle plinth]

64 is the highest a structure block can save

I don’t know what the highest a jigsaw block can place is

[half burrow]

Ah

I’m pretty sure structure blocks can go higher

if they can I gotta find out lol

[subtle plinth]

You used to be able to nbt edit them but that got removed a while ago

[half burrow]

dang

64 still massive

[half burrow]

yeah nope

[subtle plinth]

Yeah

[half burrow]

Either way seriously, you helped out a ton, and you will be in the credits of my project once it’s complete

thank you so much

[subtle plinth]

Okay this might not be the answer, but was the jigsaw you were spawning within render distance? I was working on a mcstructure display project and while it worked to a point, beyond render distance the commands wouldn't work.

This issue appears in the new version of Minecraft released today.

[uncut mauve]

Can someone tell me how to make an addon that changes the way terrain is generated, creating larger mountains?

..

[stoic owl]

I found it for the normal one it was "minecraft:roofed_tree_feature" but I am not sure how to replace htis

[stoic owl]

roofed forest

[vale cliff]

It does not spawn for me

[vale cliff]

What is name of the feature rule

[worldly moss]

Question.

Can we easily make ocean biomes with the replace biome stuff?

I havent messed with the new biome system at all

[limber jewel]

not in a straightforward way, you only get to replace existing biomes so the base terrain shape stays the same

buuut, you can create a feature rule with a bunch of "remover" features to carve out space for an ocean

there's more to it but that's the basic idea

[old minnow]

The new in beta noise stuff could be helpful there

Is there any way to prevent jigsaws from overlapping each other

[upbeat barn]

Pieces or separate structures?

[tawny cargo]

Yeah

[strong tendon]

Separete structures

[worldly moss]

[strong tendon]

Separate jigsaw systems Imean

[upbeat barn]

You can add them to the same structure set.

[subtle plinth]

This ^ otherwise, no

[strong tendon]

Yeah, that's an alternative we're considering but we don't want to lose the /locate command

And that also doesn't guarantee it from not overlapping on other jigsaw systems from another addon or vanilla structures

But just to confirm, there's no other way we can do this in the current system?

[upbeat barn]

Then unfortunately no.

[strong tendon]

Yeah unfortunate. Thanks for answering!

[solar dagger]

For Jigsaw, is it possible to spawn a structure clamped between a min and max Y value based on the world_surface projection?

I want to spawn a surface structure that is the entrance to a dungeon deep down below. But it also spawns on mountains causing the dungeon to generate in the air.

[upbeat barn]

Does dimension padding work for your use case?

[solar dagger]

Ah that should work. The tabel description of that didn’t click but now I read the paragraph in the wiki this should be very useful. Thanks

Can the pillager_outpust in vanilla Minecraft be replaced with a custom one?

[round cosmos]

Are jigsaws able to connect up to other existing jigsaws in this way? Imagine this tile is a single structure, it is broken up into 3x3 8x8 areas. I'd have a set of 8x8 walkway pieces (straight, t, 90 degree bend, etc). Can jigsaws be used to randomly select from my set of pieces to appropriately fill the inside of this 3x3 larger grid? Or I would assume I'd be better off using scripts since I can't guarantee the jigsaw generation won't expand out of this 3x3 tile area...

(blue stained glass is example tiles)

[rancid gull]

Hello! Messing around with some world gen here for an addon I'm working on. Currently having a couple issues.

Trying to add wild carrots (as well as beets and potatoes) into my villager trading addon. They're supposed to generate in forests, but I'm experiencing an issue to where they're generating in birch and standard forests, but not roofed or old growth birch. First image shows that my forest coal generation (coal blocks are for testing) is working fine with the same biome tag parameters.

Second and third image are showing fallen trees and leaves generating after my carrots do, making them generate on top of the feature.
Last image is the code for the feature rule. Any way I can get it to generate in the roofed/old growth birch and before the leaves/fallen trees?

I tried messing around with the placement passes but I'm not having any luck with before, after, first, or final, and can't find the default feature rule for leaf litter (or tree leaf litter) to overwrite the leaves.

[royal bison]

Hey guys! I have a question, from a jigsaw structure, if I use feature pool to place an structure and that structure has jigsaw blocks, jigsaw blocks still working? I mean still generating more pieces?

[subtle plinth]

No, jigsaw blocks in features don’t get trigged even if the feature is placed by a jigsaw

[royal bison]

damm!

thx for the answer

Im looking for detecting the difference between the origin and the terrain height, idk what to do now

[lyric olive]

how can i make a single_block features generate the block only if the two blocks above it is air?
the block is 3 blocks tall (multi block nonsense), i can only use the 'may attach to -> top = air' but it checks for one block not two

oh, the multiblock nonsense is not working properly, its only generating the bottom block without the second or the third part

ill have to use scripts to setblock instead

[upbeat barn]

Then use scatter features.

Like how vanilla does.

[lyric olive]

how exactly?

ill probably deal with it tomorrow

[upbeat barn]

Check the vanilla files.

[lyric olive]

anyways heres the current bugged single block features:

so i just have to make another scatter features to generate it?

[subtle plinth]

jigsaw blocks can place the snow block piles from villages

we can also place all these and I would presume the pumpkin pile also works. The mossy rocks from the mega taiga also work but they are very weird and place a ton of blocks offset fromthe parent jigsaw

there is the pumpkin pile

[hard cipher]

This is not a good think

[upbeat barn]

How?

Why would you expect jigsaws to work in features?

[hard cipher]

This is not a good thing.

[upbeat barn]

That doesn't answer my question.

[hard cipher]

That would be cool, maybe you want to generate a large structure in a specific position that only features can handle.

[upbeat barn]

That's a terrible use case.

If anything you should ask for more placement support instead of relying on features.

[hard cipher]

Indeed, jigsaw rely heavily on rarity and placement.

[royal bison]

because the origin is from a jigsaw structure, in my case I want to detect the terrain height using molang in a scatter feature and place an structure based on that

in java edition, modders simply extend the template pool class with coding, we cant do that on bedrock

[lyric olive]

done, but it still places the bottom block only

sorry for sending the message 3 times, my discord is lagging for some reason

[upbeat barn]

Take at look at the vanilla tall grass feature.

[upbeat barn]

Right so: #1067870310055022672 message

[lyric olive]

well, it doesnt work properly

it just places two of the same block ontop of eachother,

like it didnt really fix the issue i am facing

[upbeat barn]

So you have a feature rule that places an aggergate feature that places a scatter feature that places a single blo k feature that places different block states?

Are you sure youre setting the right block state?

[lyric olive]

as u can see

[lyric olive]

do i have to add even more features to place the second block with the other multi-block state?

sure ig, ill give it a shot

[upbeat barn]

Did you look at the vanilla tallgrass feature...

[lyric olive]

my block is 3 blocsk tall, not two

ill just do some testings ig

[upbeat barn]

The concept is there.

You should be able to learn from two and apply it to 3.

[lyric olive]

ill give it a shot ig

[lyric olive]

if all of the 3 rotations were correct, the block will appear normally and it doesnt break when u place a block near it

thats not the case if one of the blocks was rotated, placing a block will update it and instantly breaks the whole thing

[upbeat barn]

Then dont rottate it?

[lyric olive]

ig,
almost all of my blocks are two blocks tall, so i dont really want to add like +80 features for all of them

[upbeat barn]

Vanilla does that.

[lyric olive]

ig ill just use a single command to place the whole thing,

theyre pretty rare tho,

[lyric olive]

yeah that will fix the issue, but it will just look weird having all of the bones facing the same direction each time u find one

[upbeat barn]

Why not use structure featirss then?

[lyric olive]

if it works better that this, then sure

[upbeat barn]

All you need would be 1 feature.

[silk spire]

Is possible to edit the world gen of superflat worlds?

[oak cipher]

dont think so

[silk spire]

Well there goes my idea then

[lyric olive]

u could make a custom dimension that looks and works like the superflat world that u can modify freely

[silk spire]

As much as that's true, ive heard world gen in custom dimensions are quite laggy rn

[lyric olive]

yes bec theyre new

[silk spire]

Hence why I'm trying to avoid it for now

[lyric olive]

u can just wait for a bit until they become stable enough

[silk spire]

I just wanted to add biomes

[lyric olive]

u can with the custom dimensions one, so all u can do is wait for them to finish the thing.

[silk spire]

I guess thats true, my plan is to make superflat survival beatable while maintaining the grind that it's known for

[lyric olive]

i was considering adding a new boss to the game, that u have to summon after killing the ender dragon (a satanic boss) and with this custom dimensions, ill just make a new hell dimension that u can have access to after the ender dragon, where u can do some hell stuff in order to get the new items/hell-a cool stuff and summon the new boss

[silk spire]

I've been wanting to add new bosses as well but I heavily lack modeling/custom AI skills

[lyric olive]

gl with that, just make sure to make strongholds generate there, alongside some villages

[lyric olive]

for me tho, by the time i finish this exploration-based addon, i will be leaving the whole coding stuff to study for some 'endgame' exams, which will take a year worth of studying, so i just hope they add everything i need by the time i finish everything,

[silk spire]

That route kills the grind, I have my own ideas tho

[lyric olive]

what i hope they add:
the ability to make the entity unable to block the blocks placement (similar to how arrows/item entity works, they doesnt block the blocks placement)
new enhanced mob AI components that i can use to make some extremely complicated bosses later on
the ability to make block-entity blocks similar to how they have coded the vanilla chests (its all about making an entity works like a block that u can mine it or move it with pistons)
being able to show/hide images in the Ui from scripts without having to use titles or chatmessages
adding custom keybind for both RP and BP, like click that button to roll or something
being able to add new slots to the player like accessories or new armor slots or new slots to the inventory in general
and lastly, the ability to open an entity inventory without interacting with an entity, its more like holding ur backpack item in ur hand and right click to open it (without summoning an entity in front of u)

i just hope they add at least one of those while i go studying

[silk spire]

It's certainly a wishlist

[lyric olive]

mojang, u had only one year to add at LEAST one of those, please do not disappoint me mojang.

[lyric olive]

a good one

[royal bison]

Yeah I agree

[lyric olive]

yeah it works like a charm!

oh btw

"iterations":1, is spawning alot of structures

can i make it smaller than 1? like 0.4 or something

bec 2 years ago, i tried setting that to 0.2 for an ore, that ore wasnt spawning at all,

[upbeat barn]

That would be scatter chance's job.

[lyric olive]

well, i dont want to add 52 more files, so ill just make the remains blocks spawn in rare and small biomes

[upbeat barn]

What?

Its a field in the feature rule.

[lyric olive]

in the structure feature rule? (my brain is a little too slow atm)

ill check it out ig

[lyric olive]

i got it, how does it work exactly?
like if i put 5 in there, the block will have a 50/50 chance to spawn or not?

[upbeat barn]

That would be 5%

0-100, chance to spawn per chunk

[lyric olive]

so 50 should do it

god damn, the 'your dad remains' block is now even rarer lmao

[lyric olive]

so if i want to make the block has a 25% of spawning, do i have to put 25 scatter chance or 75?

[upbeat barn]

25

[lyric olive]

got it

[modest trench]

I can't wait till they are stable! I am looking forward to folks bringing back older world generations 😃

[lyric olive]

can i somehow place the structure ontop of lava? currently its being placed inside the lava

    "constraints":{
      "unburied":{},
      "block_intersection":{"block_allowlist":[{"name":"minecraft:lava"}]}
    }```

i tried making the structure two blocks tall, where the bottom block is lava and the top one is air so the generation appears ontop of the lava

but it didnt work at all

as u can see

i cant really use single block features bec its bugged with the onTick/custom component stuff

[lyric olive]

got it working

[boreal spear]

[upbeat barn]

Your scatter chance is saying there is a 0.40/100 chance of spawning per chunk.
Theres no need for that all of any of filter if you only have 1.
Why is there a +0?

[boreal spear]

Well... I never paid attention to that because I've always used the same model and it's always worked...

[hard cipher]

Is it possible to position the structure_template_feature if a specific block is in the path, but without replacing that block? I know it's possible to prevent certain blocks from blocking their generation but have them replaced. I'd like to know if it's possible to make it ignore the block but not replace it.

[strong tendon]

They should add a feature in editor mode where you can generate chunks only at certain "steps" like "surface_pass", "before_surface_pass" etc.

I'm lowkey asking if this already exists

[upbeat barn]

Are you trying to debug something?

[strong tendon]

Yeah

[bronze junco]

What value do I need to edit to make my structure more or less rare/spread out?

[subtle plinth]

feature rule or jigsaw structure set?

[bronze junco]

feature rule

[subtle plinth]

i think raising the iterations number makes it rarer but im not sure

[bronze junco]

Ok I will try that then

That did not work at all

It just stacked them on top of each other

[subtle plinth]

that might be the wrong value then, I don't know a ton about feature rules so you might be better off waiting for smokey because he knows features

Lower iteration and decrease the scatter chance.

I would do scatter chance 10 which means 10% per chunk.

[bronze junco]

Ok thank you

[cunning orchid]

Is there a way to limit the amount of rooms from the same type in a jigsaw structure?

I want to make a dungeon with only 3 treasure rooms at most

[subtle plinth]

Not that I know of

[cunning orchid]

I see

I managed to do a workaround, but now I'm facing another problem

The structure is supposed to generate either an extension of a corridor or a special room, wich means the end of that path

But it just stops generating the path after a few extensions and doesn't generate the special room

Sometimes it does generate the room, and sometimes it doesn't

[cunning orchid]

I just noticed it was because of the max_depth property, but it has a max of 20

So it can still stop generating it if extends too much

Is there a way to allow it to extend as much as it needs?

[upbeat barn]

Wouldnt that be #1067535382285135923 ?

[royal bison]

technically is world gen also

[upbeat barn]

Not really no. It's more suited for scripting since you're using a script function to palce a structure.

[royal bison]

okay

I'll move my question then

[shy crypt]

Plz help,so i override terrain generation, but i don't know how to override structures plz help

[limber jewel]

i'm assuming you replaced everything with air? if so, then no, structures cannot be replaced as they run in a later pass during worldgen

if you want a void dimension, you should use custom dimensions

[shy crypt]

Did it keeps the normal biome spawning

[limber jewel]

no, it's just void

the default biome is the ocean rn, but that's not useful since again, it's just void

[shy crypt]

Ohhh

why does my ore feature just doesnt work

?

[upbeat barn]

What's your feature rule?

[slim dragon]

huh whats that

[upbeat barn]

You need a feature rule to generate your features.

[slim dragon]

why does the microsoft docs dont tell me anything about this..

[upbeat barn]

What article are you reading?

[slim dragon]

https://learn.microsoft.com/en-us/minecraft/creator/reference/content/featuresreference/examples/features/minecraft_ore_feature?view=minecraft-bedrock-stable

i really dont uderstand why this doesnt work

[slim dragon]

@upbeat barn sorry for the ping, if you're not busy, more help would be very apreciated

[hard cipher]

https://wiki.bedrock.dev/world-generation/generating-custom-ores

[shy crypt]

Hey there, where do i find structure distribution json

[upbeat barn]

Vanilla's? Doesnt exist.

[subtle plinth]

Trail ruins do

[shy crypt]

Is there any way to stop /override structure generation

[shy crypt]

In the bedrock samples??

[subtle plinth]

No

It was in the games apk file when the data driven jigsaw experiment existed

#1067870310055022672 message

You can find its structure set in that zip

[boreal blaze]

Quick question, anyone familiar with getting a jigsaw structure to spawn on the surface of an ice spike biome?

Seems like the spikes are interrupting jigsaw placement but I’m unsure as to how to circumvent that.

[shy crypt]

Did the file still exist or only on the preview trail ruins added

[shy crypt]

Is there any way to stop /override structure generation

[subtle plinth]

its not in the game apks but it still works to override it

[subtle plinth]

kinda yeah

but only for some structures and ive only tested it for one

[boreal blaze]

Nevermind, figured it out.

Adding both “ice_plains” and “mutated” to the biome filter tags sorted it out.

I guess that biome is a bit “special” when it comes to trying to refer to it directly, doesn’t have a specific tag like other biomes do.

[hard cipher]

Not all vanilla ones, because 99% are hardcoded.

[shy crypt]

So no way

[runic badger]

I don't understand biomes, but how can I make something similar to this?

A flat biome, with some mountains with straight edges and a few holes.

[steep gull]

Like a mesa?

[runic badger]

Yes, but something flatter and with a lower density of mountains

[steep gull]

Try using a noise parameter that goes to about 128 blocks in height Biomes can’t be any taller than 128 blocks, so it should plateau around there

also means your mountains will be very tall, but it’s the best I could come up with

https://wiki.bedrock.dev/world-generation/biomes#noise-parameters

[runic badger]

I don't really understand these documents
When I create a biome, it always mixes with another and doesn't become complete

[silk spire]

Do custom dimensions have any way to inherit stuff from other dimensions? Like if I wanted to make a modified overworld rather than a completely new dimension

[upbeat barn]

No.

[silk spire]

so I would have to rewrite all the spawn rules???

and a manual daylight cycle

[upbeat barn]

No. Custom Dimensions is just a void world. Thats all. Its the Overworld mechanics.

Your question of "can it inherit other dimensions" includes the nether and end which it cannot. It also cannot inherit biomes nor terrain gen.

[silk spire]

So technically it would be possible to create a Y = 0 centered superflat?

Just didnt know if like the custom dimension was a complete blank slate with no inbuilt spawn rules and stuff like that

[upbeat barn]

You cant do terrain gen easily but theoretically yeah.

[silk spire]

I could use structures no?

a 16x16 chunk structure that repeats every chunk

[runic badger]

They always stay like that, they just overlap the blocks and say it's a new biome

[upbeat barn]

Yes, this is how custom biomes are. They replace vanilla biome slots which they themselves place on top of terrain.

[runic badger]

Is there a way to prevent this from happening? I'm referring to several small pieces of the biome

[upbeat barn]

Mess around with the parameters. Increase noise frquency and amount.

Target more biomes.

[runic badger]

Okay, thnks

[subtle plinth]

trial chamber structure sets cant be overwritten it seems

[dull pumice]

good day guys! hey i have an issue and i need your help and ask something. what are the reasons of crashing the game because of jigsaws?

https://tenor.com/view/cat-cute-pat-tap-gif-2439682443418826228

in your experience i would love the help.

oh its actually reported:

https://bugs.mojang.com/browse/MCPE

doesnt have a fix version or resolution for now :0

[hard cipher]

Is it possible to make a feature never generate at a specific coordinate?

[upbeat barn]

if v.worldx is a number then set the iteration to 0

Same goes for v.worldz

[hard cipher]

But does this allow the feature to still be generated in the world, but never generated at the defined coordinates?

[upbeat barn]

Yes. You just have to do some Molang.

[hard cipher]

Right, thanks

[unreal lark]

Is it possible to modify vanilla villages? I want to add a chance for my custom crops to generate in these villages
