World Generation General

[sly forge]

but i did notice with molang terrain, if you change the function sometimes the old generation can be overwritten in the chunk you’re literally in

it’s weird

[delicate trench]

Yes, they can. Goes without saying, but whatever's evaluated latest in the feature tree is what shows up in-game. If you were to, say, also place a structure feature and tree feature that intersect with that position, assuming both placements succeed, you'll see the rest of the structure and tree feature in the surrounding positions.

[olive ridge]

I'm currently dealing with a strange bug where some world gen isn't placing anything after updating to 1.20.20, but no errors are thrown

[modern pewter]

Lots changed in 1.20.30 I'd update your files and code

[sly forge]

he already updated

[sly forge]

try 1.20.30 ig

i don’t have issues so idk

i really don’t know

[modern pewter]

I got all mine working once I moved everything to 1.20.30/1.20.40 including manifest min version. I've spawn stupid numbers of stuff.

I kept thinking it was broken because of grounded and other issues but I just dind't understand how hard it is to place stuff with a large solid fountain.

Maybe turn off gounded and test it

[sly forge]

im…having no issues with grounded

[modern pewter]

What size are your structures? Do they have solid foundations?

[sly forge]

wdym by solid foundation? and its 31x98x31

[modern pewter]

the first layer of the structure blocks. For examle my trees with a small foundation but massive branches place way better than a park or field that has a large foundation.

[sly forge]

i mean the base of the structure is like

3 blocks

but that part is underground

[sly forge]

hmm

it should work perfectly fine

[compact crescent]

what features other than ore_features can stop chorus plats from generating? ore_feature makes a lot of lag and breaks on your render distance, i am trying to clear the end dimension from everything except end gateways.

[upbeat barn]

Try single block features + scatter feature like other void generation?

[sly forge]

doesn’t work fully unfortunately

and there’s actually no way to fully get rid of the small islands, those behave similarly to a dark oak forest with a void pack

except small islands cant be disabled by feature rules

[compact crescent]

that doesn't work on chorus plants

[compact crescent]

setting ore_feature to 17 blocks seems to get rid of all chorus plants by replacing end stone with air, but it's so laggy, do you know an efficient way to do it?

[sly forge]

irdk

[modern pewter]

Question: What does branch_altitude_factor do?

[compact crescent]

geodes? is it more lag efficient than ores?

i don't have to get rid of small end islands by the way, large islands, chorus plants and end cities have to go, end gateways and small end islands may stay as long as they don't get distorted by the chorus plant clearing method. so what i want is an end dimension with only end gateways and full small islands

[raw cedar]

How to solve

[sly forge]

structure void

[mint juniper]

/give @s structure_void

fill every block that you don’t want to clip into the ground like that

[raw cedar]

Thanks

[modern pewter]

You should be able to use fill with keep if you need to do a larger area. I need to do this too.

[compact crescent]

i have dealt with the cities already, and i probably can find a way to save the small islands shape. send it to me please

[scenic harbor]

Hello, I would like to create a feature that allows me to create a Map with a spawn biome defined from coordinates A to coordinates B. Is it possible or not?

[upbeat barn]

Hey y'all, i made a feedback post about Bedrock's custom world gen system. If y'all can read it and leave feedback there that would be appreciated

Can't access the link

But would love to check it out 👍

Question: Can I only use structures in that 1 world gen type or can I use them in others too?

[raw cedar]

I need help

Structure

Feature rule

feature

In Game

What's happening

Why does it generate like this?

Because

I can't take this generational shit anymore

I just wanted to generate a village

There must be someone experienced in word generation here

[modern pewter]

Use structure voids around it, I think. Do't allow it to replace those blocks. Are 2 options

[raw cedar]

Using Structure void doesn't do any good

I'm using this shit

It's not doing anything

I've tried everything

The structure only generates faith like shit

I will have to remove the addon framework

I've been in this structure since 8 am

The structure does not create the right

It just generates like this

I don't know how to solve this

What fucking structure

I hate

[upbeat barn]

Calm down with the curse words. Open a post so it doesnt flood the channel

[raw cedar]

I got tired

I give up on this structure

[modern pewter]

How big is it?

[raw cedar]

28x10x32

[modern pewter]

try setting x/z to (-16, -15)

[limber forum]

Try splitting it into sections, and the main section have always active command blocks delayed in more or less 100 ticks that load the rest of the structures, using the /structure command

Or a dummy entity with the same idea

[raw cedar]

I already gave up on her

[worldly oxide]

where do i get info on using a random building generator throughout ?

[sly forge]

what exactly do you mean

[worldly oxide]

world gen for custom buildings

[sly forge]

idk what you mean

do you just mean a custom structure or do you mean a random-layout structure?

[worldly oxide]

Like when villages spawn or random builds.

[sly forge]

so random-layout

what exactly are you trying to make?

[royal bison]

you mean randomize a house? you could use weighted feature

[worldly oxide]

Spawning buildings.... randomly through the world when a new chunk

A chancd

Chance

Scatter or something

[royal bison]

you cant via features because of chunks limitations, use entities instead

[worldly oxide]

Chunk limitations?

I thought we were able to use structure blocks to scatter chance builds around

[royal bison]

the structure size limit is 48x48, otherwise your structure get cuts

thats what I mean

[royal bison]

you can under 48x48 size

[worldly oxide]

Oh ok

[royal bison]

you cant scatter an structure 100 blocks far for example

[bitter fog]

Is anyone else here experiencing the structures not generating thing

[royal bison]

nope, all is working ok

[bitter fog]

Huh

Cuz for me all the custom structures in my addon just doesnt generate

The mcstructure files arent being recognised

/structure command doesnt seem to spawn any structures at all (even the knes that were working

[scenic kraken]

hey, is there a way to put now blocks with rotation

in 1.20.50 they added the block rotation

for structures

[summer iris]

I think they rotate with the structure by default

[upbeat barn]

If you mean custom blocks, using the block traits should work now

[scenic kraken]

alr

[scenic kraken]

I'm trying to generate a plant with rotation naturally but for some reason it is not generated, does anyone know why?

[royal bison]

In my experience, it still doesn't work.

this happened when I used /structure with 90_degrees

same with trapdoors

and minecraft:queued_ticking stops working when I generate the customs blocks with /structure

[summer iris]

Is there any way to prevent chorus flowers from generating?

[thin fox]

Are you able to replace them with air through the final_pass

[pulsar nebula]

Is it viable to add custom stalactites and stalagmites

[delicate trench]

Growing plant features might be what you’re looking for

[modern pewter]

Question: Can you use structures in grid features?

[old minnow]

where do I find all the features?

the vanilla ones

[upbeat barn]

In the BDS zip file or your windowsapp folder

[open valve]

I have a question...

The features and features rules does work in minecraft bedrock 1.20.51.1 ?

[upbeat barn]

Update your manifest min engine version to 1.20.50

[open valve]

Nothing

[open valve]

False alarm!
Yes, it worked lol.
I just forgot to change the format_engine in the manifest.

[royal bison]

isnt 1.20.30 the min? now is 1.20.50?

[upbeat barn]

Its always good to update your min engine version 🙂

[royal bison]

true, except if a function is deleted xD

[uncut yoke]

Does anyone know how to edit world files? I'm looking for a way to have a world generate Optimally like the Java "Tunnelers Dream" except it generates all the Overworld Biomes instead of just one.

[sly forge]

i don’t think you can do that by editing world files

youll have to use molang-based terrain

[uncut yoke]

I'm not a modder, so I do not know if I am even asking the questions correctly. But what is Molang-Based Terrain?

[molten kraken]

i want to get started altering the world generation. i want to make rocks start generating on the surface

[sly forge]

it’s basically like making the terrain yourself except you use Molang, a custom language, to make the mathematical calculations to allow it to generate

similar to how Minecraft terrain is made

just…not as advanced

and you can very well make a flat world with biomes using it

just villages wont generate on top

because Mojang is dumb and wont let us modify that stuff

change it to 1.20.20

[soft turtle]

Ok

[sly forge]

both the feature and the feature rule

[sly forge]

idk then

[simple pond]

@sly forge

[sly forge]

wasnt me who said it

[compact crescent]

i think he is asking you to answer it, although i don't know why he choose you particularly?

[uncut yoke]

So this is a 3rd party algorithm or app\service that one can use to generate customs maps like adding features like biomes to a world template like Java's "Tunneler's Dream"?

[sly forge]

she was trying to show me i said something i didn’t say is what happened

[sly forge]

no its not third-party

its part of Minecraft’s addons API

[compact crescent]

@sly forge do you mean behavior pack features and feature rules? or is it something else?

[sly forge]

???

first off what are you talking about

[simple pond]

What the.

[compact crescent]

i am replaying to this message #1067870310055022672 message

in response to this message #1067870310055022672 message

[delicate trench]

Yes, the Molang goes into features and feature rules.

[junior orbit]

I am having issues, with feature rules!!! My large structures are being cut off by the chunk bounds! Any ideas???

^^^

I have changed my Rule Distribution to strictly

      "iterations": 1,
      "scatter_chance": 100,
      "x": 16,
      "y": "query.heightmap(v.worldx, v.worldz)",
      "z": 16
    }```
So that it is placed on directly 16 / 16 instead of randomly.

[upbeat barn]

Change x and z to 0

[junior orbit]

check it

was updating

i changed to 16 / 16

still cuts off

but i dont understand why the structure directly above it, is clearly within 2 chunks, and loads fine

[upbeat barn]

It needs to be 0 and 0 so its in the corner of the chunk

16 and 16 is the chunk outside

[junior orbit]

And then, what should the scatter dist be?

can it be like:

      "distribution": "uniform",
      "extent": [
        -2,
        2
      ]
    },
    "y": 0,
    "z": {
      "distribution": "uniform",
      "extent": [
        -2,
        2
      ]
    }```

or should those be 0 as well

[upbeat barn]

Should be 0

Any other features can be extent but large structures need to be strictly loaded within chunks

[junior orbit]

Kkkk ty

[modern pewter]

oh this is my fault. I told them 16's.

[junior orbit]

No problem! Thanks for the help!

[modern pewter]

Do you by chance want to share your tree structures?

[junior orbit]

Sorry not mine to share!!

[modern pewter]

Dang, randomize tree designs are hard to make. We need a tree sharing party

[junior orbit]

Those were not random I believe. They are manually put together. Regardless a resource sharing party would be awesome

[modern pewter]

lol, yeah that's my point.

But it 10 people all gave their trees to each other. We'd have 90% that felt random to us

[uncut yoke]

Ah, okay so you're indicating that there is an API function "Called Molang" that can be used to change the way worlds generate. Okay, can you link any reference documentation to start with using Molang? Like I said I am not a modder so I've never used their API. I just looking for information to even start to know what is involved in the end goal I am looking for. Seams quite complex, which I suppose may play a part in why it looks like this really has not been done yet. Thanks.

[sly forge]

its not a function its a custom programming language created by Mojang for math calculations

also it has been done multiple times over

as for a tutorial i think theres a few on wiki.bedrock.dev

itll get yah started

[uncut yoke]

What I ment with not been done is more along a plugin\web app\set of instructions for non developers/mod builders to use to put in the perimeters they want and get an output such as an in game command\string or even world DL file that is what the user put in.

[uncut yoke]

Thanks will check this out.

[delicate trench]

@uncut yoke This might be a good starting point for you https://wiki.bedrock.dev/world-generation/heightmap-noise.html

[uncut yoke]

Thank you @delicate trench and @sly forge. This is some pretty heavy content and in time I might be able to figure it out. It seams lime there is clearly a lack of knowledge that is making this look incredibly daunting. There is clearly some thing I dont know anything about regarding this that I don't know what to ask for. It's the classic "Don't know what I don't know" connundrum. I've only barely been able to understad out how to install addons in to a dedicated server. Other than that; I've never done anything technical with MC. This looks maybe kinda similar, but I'm not sure. Again thank you for the help I'll dig in and see if I can at least figure out inteligable questions to ask later.

[sly forge]

[modern pewter]

Questions: Can I use structures in a grid feature system?

[sly forge]

uhhh yeah?

i thought everyone knew that lmao

[modern pewter]

No, I've only used them in the one structure feature

I'd like to make a town/village

and I need a grid to do it

[sly forge]

oh uhm

uhhh

i…don’t think it works like that lol

unless u want an infinite city

ur probably better off using scripts or scoreboards + command blocks

[royal bison]

I did a village by using a central structure and entities

I showcased it here
https://discord.com/channels/523663022053392405/1188004425684492288

[modern pewter]

So what are you talking about that every one knows

[sly forge]

you didn’t provide enough information

[sly forge]

this question implies you asked if you can use the grid distribution for structures

[modern pewter]

Whats the difference

[thin fox]

Using the grid is pretty common in world generation

So most people know about it

[modern pewter]

Could I use minecraft:sequence_feature instead for a town layout

[molten kraken]

is it possible to make the end / nether just a empty void?

[wide grotto]

yes

these in your dimensions folder in your BP

should do it

[upbeat barn]

Void generator only works for Overworld

[bitter fog]

Is there a way to generate a structure bigger tban 32x32?

[molten kraken]

ily bro

[wide grotto]

it worked for those dimensions

I tested it

the overworld remained unchanged while those two dimensions were void

[molten kraken]

@wide grotto can you give me a link to dimension documentation, i cant find anything

[still wing]

https://learn.microsoft.com/en-us/minecraft/creator/documents/datadrivenoverworldheight

[molten kraken]

@still wing where can i see all dimension components?

or the vanilla dimension files

[still wing]

that’s all we have currently

[molten kraken]

damn

[still wing]

also vanilla dimension are not data driven yet

[molten kraken]

does it mean we cant change anything else, or does it mean we have to find that by ourselfes

[still wing]

we can’t change anything else

[molten kraken]

sad

can i make overworld generation in nether tho?

[still wing]

I don’t think you can

it might be possible using features? but I doubt you will have the exact overworld generation

[civic niche]

did i do something wrong with my code here? I cant seem to have the structures generate anywhere but im not getting any content logs telling me the code is messed up. Im pretty new to this stuff so any help would be awesome

[modern pewter]

Question: Anyone else had structures just not validating for features? Hordes of mine did after this last update.
[FeatureRegistry][error]-edited Structure_Gallery_07232 | olctd:lw_tree_b1_feature | minecraft:structure_template_feature | structure_name | Structure mystructure:olc_tree_b1 does not exist

[bitter fog]

im also having problems generating stuff in the nether

idk if its the biome tags

[royal bison]

I want my structure to be generated with the same probability as the vanilla villages, what value should I put in scatter chance?

[pulsar nebula]

is the Geode feature broken by chance

[jolly ember]

No. It should be working just fine.

[candid cape]

uuuhhh... why?

[upbeat barn]

Upgrade your min engine versino to 1.20.50

[summer iris]

what vanilla feature rule handles placement of suger cane

[velvet spade]

reeds feature

it still uses the oldschool name as its feature and rules

[royal bison]

Hello! Im using command blocks to spawn entities on my structure but some times its not spawning nothing and I have to place the command block manually again, how can I solve that?

[limber forum]

Did you put the command in Always Active?

[royal bison]

obviously

it works, but sometimes not

[limber forum]

Try adding tick delay

[royal bison]

it has

[summer iris]

tick delay 2 and ensure the fucntion works

[royal bison]

The function works, a very low tick delay causes the function to be executed many times until it loads the chunk and then the command block it is deleted so I put a tick delay of 999

could that be the problem?

[summer iris]

use tick delay 2

that value you set is way too high, causing it to take long

[royal bison]

And how do I solve the problem I told you about?

a very low tick delay causes the command block to be executed several times before being removed

[summer iris]

i use tick delay 2 in all my structures and it works great

if the tick delay is below 2, the command block will try to execute as soon as the thing is placed in a chunk you are yet to enter. Tick dealy 2-4 prevents that

[royal bison]

I used 3 and had the problem I told

then I changed to 10 and same problem

[summer iris]

you sure the command block is always active?

[royal bison]

yes

[summer iris]

and you sure the command work? I use functions to replace the command block to air

[royal bison]

I used an entity to remove the command block

I clarify that this problem does not always happen, it happens rarely, but it happens

[summer iris]

interesting

I do not know then..

[royal bison]

I will try to use a function and try

thank you for your time

[limber forum]

use normal command block

[royal bison]

wdym by normal command block?

[limber forum]

Impulse command block

[royal bison]

What would change with that?

[limber forum]

An impulse command block is the default block type; it executes only once when activated.

A chain command block executes every time when triggered.

A repeating command block executes every game tick as long as it is activated.

[royal bison]

aah I will try then

thx

[limber forum]

np

[royal bison]

the same problem persist :(

I used functions and the same problem

[limber forum]

Honestly no clue then, sorry

Is there a list of all the placement_pass options and their order? I tried looking but couldn't find anything.

[jolly ember]

?placement pass

eh . let me copy paste .
Placement Passes
Placement passes can just be thought of as a named ordering for when placement of a feature rule’s target feature should occur. Nothing special occurs during a pass; it’s just a name.

The available passes are:

pregeneration_pass
first_pass
before_underground_pass
underground_pass
after_underground_pass
before_surface_pass
surface_pass
after_surface_pass
before_sky_pass
sky_pass
after_sky_pass
final_pass

Note that the pregeneration pass is reserved for carver features."

That looks like the right order if I'm remembering correctly. @quasi dove ^

Though note that while this should be the order, features still find ways to not abide by them. Placement passes for lack of better words, "can work in mysterious ways" but for most things work fine.

[hushed knot]

[upbeat barn]

@quasi dove

[upbeat barn]

btw, we have a new faq bot

[quasi dove]

ty ty, I appreciate it!

Also after a bit of testing it seems like feature rules are limited to loading a 3x3 chunk area around them. Which also limits any structure to 48x48. Is this correct? And if so is there a way around this?

[upbeat barn]

You can use aggregate features to place structure chunks next to each other. Other than that, you could use the cmd block workaround(the cmd block loads the other parts of the structure)

[quasi dove]

In regards to the cmd blocks, how would that work when the chunks around them are unloaded. Does it just load them when the player comes close enough to load those chunks, or does it do it generation? If it's during generation it seems like it'd still be trying to load a structure in an unloaded area and fail (or queue it which would have the same issue as the player coming near).

For the aggregate features, does offsetting the origin of a feature into a separate chunk load it? So far I've only tested with the feature rules, but if features themselves load their chunk origins that would probably solve it.

[upbeat barn]

The cmd block would be in a repeating state that executes a function. The function will load the structure than turn itself into an air block(or whatever block you prefer)

[quasi dove]

Hmm, I see. And it loads in when a player gets near enough to have the repeating cmd blocks loaded, I presume? I also just realized the way I tested kind of confirms features, at least scatter features, do not load the chunk they originate in. Just started the other day tho so I could be missing a number of things

[upbeat barn]

Yep, the structure would just load in

[quasi dove]

Gotcha, thanks! Would you mind explaining a bit more about the aggregate features method you suggested?

[upbeat barn]

https://wiki.bedrock.dev/world-generation/feature-types.html#aggregate-features Last I tried anyways, you can offset scatter features into other chunks and it will load fine

[quasi dove]

Hm, I'll take another look but I don't think it works anymore if it did previously. For small features it probably works the majority of the time b/c it would be within the 3x3 area. I made a structures with a few different sizes to test and everything outside the 3x3 chunks was cut off or if completely outside didn't spawn at all.

[junior orbit]

Hey! @modern pewter @upbeat barn Any idea what my cave issue could be!!
This is my rule, but i am not seeing any mushrooms spawn deeper into the caves, and in some large patches....Im simply looking to cover the entire ground, all levels of the cave, and then i will dial it back and tweak it.
As you can seem there are no mushroom on the lower level. or to the side. I have tried to add "deepslate" to the replaceable blocks array. And still nothing. I have tweaked a ton with the distribution, on the y pos. and the surface pass value.
At a loss...

As you can see, the y coordinate is within range of my rule distribution.

[wide grotto]

how are your frames so good with that many of those mushrooms?!

[modern pewter]

I have no idea. This is byond my current skill set.

[misty pivot]

I really don't think having that many mushrooms should lag the world...unless they all having ticking components.

[junior orbit]

im not on dev version. only loading 10 chunks or so. and a 3060ti maybe? not sure what else it'd be

[junior orbit]

damn okay, ty

[junior orbit]

yea i could lot a lot more, doesnt seem to impact it too badly

[jolly ember]

I suspect it's your biome filter. I'm guessing that not all "caves" have the "caves" biome tag. I don't see any other issue although I haven't touched a veg patch feature in over a year. Worth a test to change that to something like "overworld" or make it ubiquitous.

scatter chance is what determines how often a structure spawns. it ranges from 0-100

[summer iris]

I have mine set at 1, 2000 and it works great

[upbeat barn]

Iterations and scatter chance?

[summer iris]

Iterations on 1 and Scatter change is set to 1-2000

[delicate trench]

Why set it to anything over 100?

[sly forge]

incorrect

its set to 1 and 1/2000

scatter chance also uses fractions

and apparently decimals, but fractions give a little more control

and remember im the one who set it :p :3

do I have to create new world every time I change something in feature or feature_rule?

[upbeat barn]

You can just go to new chunks

[ionic cloak]

One message removed from a suspended account.

[dawn dune]

Working hard??

[upbeat barn]

What?

[upbeat barn]

feature rule needs to be 0 for x and z so it's chunk aligned

[dawn dune]

They actaully currently tryna fix it?

[upbeat barn]

They are yes

[upbeat barn]

You may need to ease up on the restrictions then

[summer iris]

may I ask why fixed_grid?

iirc that makes the feature generate dead center in a chunk

and there is no random placement for it in a chunk

[ionic cloak]

One message removed from a suspended account.

[summer iris]

also, is use

"extent": [0, 15]

for structures larger than 16x16, I do 0, 31

seems to work mostly, but dunno if that's the way to do it lol

[junior orbit]

Hey man any idea about this! @upbeat barn It didnt end up being biome filter either

[upbeat barn]

Just saw this, have you considered using scatter features and single block feature to place all the blocks in a chunk instead

[junior orbit]

I have not tried that.. ill get back to you

[upbeat barn]

Vegetation issue itself could be the problem

[hard cipher]

y": "variable.random = (Math.random(50, 10)); return variable.random > (query.above_top_solid(variable.worldx, variable.worldz) 40) ? -999 : variable.random;",

what's the problem with this?

I use it in feature rule, but it gives an error

and I don't know the reason for the problem

[upbeat barn]

What's the error?

[upbeat barn]

(query.above_top_solid(variable.worldx, variable.worldz) 40)
This seems to be the issue

[hard cipher]

Are they underground structures, can't the "top_solid" component be used?

[scenic cipher]

can you replace vanilla structures with custom ones?

[upbeat barn]

No

[scenic cipher]

oh rip, so there is no way to make like basically yung's better structures on bedrock?

[upbeat barn]

That is correct

[scenic cipher]

dang, well hopefully one day

Scatter chance is on a range from 1-100

Do custom biomes work, or do I need to mix and match features to get the same effect?

how to put structures near villages?

[grand silo]

Hello hello, it's been a long time since I've touched the addon I take care of (few months). I heard some things about features changed? Pretty much all of the addon relied on structures and features. What exactly changed, what do I need to change? Also, are noise biomes still viable? I heard talk of those back then as well

[upbeat barn]

Your manifest.json needs to me min engine version 1.20.50 now. Noise biome still works

[grand silo]

Thank you!

[tight ridge]

I can remove lava from nether???

[wide grotto]

like remove it or replace it

[muted ether]

You should just wait for biomes and Nether features to be fixed and released. It's not worth the performance loss right now.

[modern pewter]

Is there any way to disable all world gen but 1 custom one

I have an empty world in flat. I want to world gen 1 structure. But if I turn on world gen it all turns on. Can I disable all of it but the custom ones?

[muted ether]

Do you mean features, like foliage and ores? You can't really disable vanilla structures or biomes right now.

[modern pewter]

Yeah I want nothing.

[cosmic wing]

How can I make a custom dimension that used the end portal block?

My plan for my addon is making end portal frames crack and you shove something like a Ech Shard in it to make a custom dimension.
How can I do so?

[upbeat barn]

Custom dimensions are not possible

[royal bison]

custom dimensions are not possible, but you can simulate them with complex noise system in world generation

[muted ether]

Sorry then. Looks like they're working on things, though. Maybe later this year?

[simple pond]

that's our thing.

[royal bison]

wdym?

[cosmic wing]

Like make generation in a dimension like the over world?

[royal bison]

in the end

and in coordinates extremlly high

[cosmic wing]

Ok, but how would I give it's own vibe?
(Like sounds, shaders and lighting?)

[royal bison]

use fog

[cosmic wing]

Like force someone when joining this "dimension", it feels like it's own atom sphere

[royal bison]

the shaders cant be modified in-game

[cosmic wing]

Can you give me link?

[royal bison]

its a command

[cosmic wing]

Oh

[royal bison]

you can also create custom fog

[cosmic wing]

I'm just a bit new in making dimensions

Then, how would I prevent anyone from sneaking off the dimension and make it unnoticed?

[bitter fog]

Does anyone know how to generate structures in the nether?

[sly forge]

you cant

srry

[simple pond]

you can

have you even watches our dev process

or is intentionally hiding our method from others

[steep socket]

hey

I got a problem with my minecraft world, is this the correct channel to ask at 😅

[simple pond]

Is it addon related ?

[steep socket]

nope, my world vanishing

my world just randomly disappeared from the mc menu but it still exists in the mc world files..

[simple pond]

then this isn't the place

[steep socket]

I can tell, perhaps where or what would the place be..

[sly forge]

#off-topic

or possibly the official minecraft discord in the bedrock mechanics channel

[steep socket]

thanks

[young nest]

is editting minecraft village structure nbt files affects how village generate?

[upbeat barn]

You can't edit vanilla structures

[bitter fog]

Hey guys is there a way to allow certain blocks to intersect with structures?

Im not sure how

[simple dust]

Guys, I want to start to learn world generation, so today what can we do for the world generationmodding

[undone lagoon]

is it possible to change the grass colour of a biome?

[upbeat barn]

Not feasibly. You can edit the colormap in RP iirc

[undone lagoon]

oh alright

cool

[summer iris]

How would I make a feature not place below 500 x or z coords from spawnpoint, but have it place above 500 x or z coords with an iteration of 16?

[muted ether]

In iterations, something like: math.abs(v.originx) >= 512 || math.abs(v.originz) >= 512 ? 16

[summer iris]

Thanks :)

[inland panther]

Quick question, I believe you aren't able to put features and feature rules into subfolders

Did that change since they made them stable?

[upbeat barn]

Uh no you can

You can always do that, but the id needs to match

[inland panther]

Really? Thought they had to match file path and all so you couldn't

[upbeat barn]

Wdym?

[delicate trench]

You can, just make sure the identifier of the feature is the file path starting after "features" (ex: namespace:folder/folder/custom_feature

[upbeat barn]

^^^

[inland panther]

Ah

Thanks

[delicate trench]

And the name of the file should stay custom_feature or whatever the equivalent is

[inland panther]

Related question if my structure's path is structures/test/build.mcstructure, do I need to do /structure load test/build

[upbeat barn]

yes

[inland panther]

Alr thanks

[muted ether]

You actually have to include the path as part of the identifier for features. For feature rules, only the file name must match, not the whole path.

[inland panther]

Thanks

[round cosmos]

Very real

[junior orbit]

@upbeat barn yoyoyo!
Any idea why my structures are not spawning with the correct "void blocks" inside the structure?
Grass / etc keeps spawning inside.
As you can see, my saved structure is covered / filled with void blocks.
just the inside seems to have objects spawn.
Attahced is the rule as well.
testing with lighthouse / outpost, you can disregard that mixup

Figured it may be the placement_pass. but messed around with those and nothign

[upbeat barn]

Void blocks means you're allowing blocks to intersetc with it, your insides should be filled with air when youre exporting the structure

[abstract carbon]

Where do I get the vanilla biomes? And also how I add my custom blocks like custom grass and dirt blocks?

[ember adder]

How could I generate structures in 1.20.50?

[bitter fog]

Features + feature rules?

[ember adder]

✍️

[karmic barn]

Is it no longer possible to edit vanilla biomes in 1.20.60?

[simple pond]

try using chungus feature biome template

[karmic barn]

I'm currently only trying to edit a vanilla biome such as the plains biome, which worked fine before 1.20.60, but after the update it stopped working. Editing a vanilla biomes surface_parameters and surface_material_adjustments no longer have an effect along with other components.

[abstract carbon]

How do I add trees or structures in that addon?

[misty axle]

i had a quick question does anyone know how to remove spawners from dungeons and things like that in world generation ?

[wide grotto]

You can't edit vanilla structures

[bitter fog]

Just wondering, what are the biome workarounds?

[simple pond]

You do Big chunguses 😄

[bitter fog]

Aight

[bitter fog]

So I ah, did a big oopsie

I'm using big chungus' noise biome generator

It's floating

[bitter fog]

So I feel like is messed up the feature placement order of any feature file under biome

[junior orbit]

@upbeat barn yoyo what rule values do you suggest to fix these super structures from cutting off.
Id like them to be in the air like this. And im trying to create them on x:0, z:0. what else do i need to change so they dont get cut off?

@muted ether ^ 😄

[muted ether]

Busy, sorry!

[dense crow]

@leaden furnace @junior orbit I, like you, tried all sorts of ways to fix the problem of the cut structure

For a while I thought this was a bug

The jigsaw block can help solve this problem but the bad news is that mojang doesn't update it for Bedrock

The good news is we can wait for this, I'm so excited

[upbeat barn]

Add the grounded constraints

[acoustic horizon]

the what

like this?

"constraints": {
      "grounded": {}
    }

[upbeat barn]

Yep

[acoustic horizon]

Yup that fixed it, thanks!

Now, how can I actually edit the vanilla ones?

I pretty much want to replace vanilla trees in forests with my custom ones

And this kinda seems like I am adding new structures to forest rather than replacing the existing ones

[leaden furnace]

Maybe try to replace minecraft:air with minecraft:oak_log, if it has the grounded constraint maybe it would replace the logs and place the structure(if your new tree is bigger than oak trees). I'm not sure how is evaluated "grounded " tho. According to the wiki :
"The optional "grounded" component ensures the base of a structure is not overhanging into open space — air, water, or lava. All non-structure void, non-air blocks along the bottom layer of the structure are considered; if air, water, or lava is beneath even one such block, generation will fail."
As the bottom layer below logs will be likely grass or dirt it would maybe worth to give a try?

[round cosmos]

Apologies if this is a dumb question, but how can I generate patches around a structure feature? I seem to recall some kind of old feature like a sequence, but I don't know if that has since been removed. Thanks!

[round cosmos]

I have a patch feature based off the wiki example, and that generates fine by itself. I also have a structure feature, again based off the wiki example, which also generates fine.

I then have this sequence feature which should spawn the patch and the structure:

{
    "format_version": "1.13.0",
    "minecraft:sequence_feature": {
        "description": {
            "identifier": "sr:pillars_feature"
        },
        "features": [
            "sr:pillars_structure_feature",
            "sr:patch_scatter_feature"
        ]
    }
}```But it only spawns the structure and then not the patch. If I reorder it so the patch is first it won't spawn anything. Seems like the patch is failing somehow

Fixed it. Patch was trying to offset itself by world height

[round cosmos]

Now we struggling with the simple things 🔥
For some reason my structure feature is only spawning facing one direction

Even though I have "facing_direction": "random"

Hm upon forcefully rotating it by setting it to some fixed value like "west" I have realized that the structure rotates from the lowest x, z coordinate, not the center. This is very annoying lmao

// features/statue_a_structure_feature.json
{
    "format_version": "1.13.0",
    "minecraft:structure_template_feature": {
        "description": {
            "identifier": "simple_ruins:statue_a_structure_feature"
        },
        "structure_name": "simple_ruins:statue_a",
        "facing_direction": "random",
        "constraints": {
            "block_intersection": {
                "block_allowlist": [
                    // ...
                ]
            },
            "grounded": {}
        },
        "adjustment_radius": 4
    }
}```I can't seem to figure this out. If anyone knows please chuck me a ping 🙏

Here's my feature file, and a screenshot in-game of 3 structures all facing the same way (every structure is facing this way lmao)

(This is with the structure outside of the sequence because I was worried that was causing it - Spoiler alert, it wasn't)

[jolly ember]

Might want to use an aggregate feature instead. Sequence features offset the feature origin by the highest point of the last feature (they work as intended now😅 ). And yes the rotation point of features is on the corner which I agree is super aggravating. Nothing seems wrong with the structure feature at cursory glance. Maybe chuck out the empty block intersection constraint. And the grounded too if that doesn't work. I can look at the full path (maybe tomorrow though, its rather late here haha.)

[round cosmos]

The block intersection isn't empty, just commented it out so it wouldn't be too long :)

No stress, thanks for the message! I'll give aggregate a go the next time I open this up

[jolly ember]

Sounds good! If you need any help or want to work through DMs feel free. It's the least I could do after getting into WG in the first place because of your FRG. That feels like so long ago now. Time flies.

[round cosmos]

Haha I know right! Shame I haven't touched world gen in so long...
Feel like a noob again 🤣

[round cosmos]

I have no explanation as to why it works now. All I did was change the scatter chance numerator and denominator

So turns out just using a float instead of the n & d object prevents the "facing the same way" issue

@jolly ember You wouldn't happen to have some pro tip for correcting centers when rotating? Due to rotating about the corner instead of the origin it makes the block patch offset from where the structure spawns. I could correct this using four variations (one for each rotation) and offsetting accordingly, but before I do just making sure there's no proper / easier way. Cheers

I mean I'm using regolith so I might as well just write a quick filter to generate these instead of doing it by hand

[jolly ember]

Unfortunately thats what I do. That is, create a scatter feature for each rotation and position it back to center. Helps avoid chunk cuts too (that is for the most part 😅 ).

[round cosmos]

Thanks for the help. I've got a decent system working, the only annoying thing is that it requires so many files lmao. Feels like early days all over again

Luckily not needing one file per block anymore though

[jolly ember]

Ah yes the 'good' & 'old' days. I think I still have some of my old stuff on a laptop... somewhere.

Also found this a bit helpful but it looks like you've got things covered. Apologies for my *advanced *chicken scratch haha.

[jolly ember]

Probably should clarify this too.

[acoustic horizon]

How to make my structures spawn a bit... rarer

too many stones

[upbeat barn]

lower your scatter chance

[leaden furnace]

With a mix between iteration and scatter_chance in the feature_rule(into distribution)
I have a frozen cabin that is spawing rarely with this
"iterations": 1,
"scatter_chance": 2,

It needs a couple of tries to find out the right setting tho

[acoustic horizon]

Thanks!!

[leaden furnace]

You could as well make different size of rock formations to get more variations, and put each structure feature into a weighted feature

[acoustic horizon]

Yes I will

[acoustic horizon]

What exactly is scatter_chance?

[upbeat barn]

The chance it will place your feature in a chunk

[ionic cloak]

One message removed from a suspended account.

[acoustic horizon]

The higher the highest the chance?

[leaden furnace]

Yep, it doesn't look like that at the first glance, but even a low scatter chance still generate some structures. My scatter chance is 1/50 chance(2 is 1 /50 as 100 is the max), but in an ice_plains biome as small as 320x256 there is already 320 chunks. Then 1/50 chance on 320 chunks is enough to have some structure(there is between 0 and 3 structures in my case depending the size of the biome)

[median spade]

what biome tag to make a structure spawn in cold caves only?

[upbeat barn]

Wdym cold caves?

[median spade]

like caves

but in cold biomes

[upbeat barn]

You could just use the cold biome tag and place it underground

[median spade]

it would have to be cold in the surface

[upbeat barn]

Caves dont have a tag unless theyre a biome

[median spade]

hmm what abt jagged peaks

like the ancient city?

would i just do the samething execpt replace the tag as jagged peaks?

[upbeat barn]

Sure

[median spade]

like this?

[upbeat barn]

Sure

[median spade]

thank you

its not working

ion see it

[leaden furnace]

You have a scatter chance of 0.8 it means less than 1% (it's between 0 and 100, the higher the better chance it will spawn the structure)

I mean between 1 and 100(I don't see why we would create a feature if there's no chance for it to appear ^^)

[median spade]

oh

ima put it at 10

[leaden furnace]

yep , even higher if you are using a test world, just to see if it spawns and figure out if your feature is working, and adjust later the scatter_chance. edit don't set it 100 if you don't want your entire biome filled lol(true story..)

[median spade]

didnt work its on surface 😭

[leaden furnace]

because you used "y": "query.heightmap(variable.worldx, variable.worldz) + 0"(meaning exactly at the surface), and maybe grounded in your structure feature. You need to remove grounded if it is in your structure feature, and change the line
"y": "query.heightmap(variable.worldx, variable.worldz) + 0", to specify the Y range you want to spawn your structure( below 63 at least, it depends how deep underground you want your structure)
Edit maybe don't remove grounded it depends how your structure is supposed to spawn.

[median spade]

bouta test that rn

[leaden furnace]

Post your structure feature as well in case of

[acoustic horizon]

How to fix:

[FeatureRegistry][error]-Feature rule minecraft:forest_surface_trees_feature can't place internal feature type.

This is my feature rule

And this is my feature

Trying to totally vanish oak forest

[upbeat barn]

Set your min engine version to 1 20 60

[acoustic horizon]

somehow I feel like I did vanish them? not replaced though

[acoustic horizon]

In the manifest no? It is already 1.20.60

[acoustic horizon]

World gen only changes never-loaded chuncks no?

I pretty much dont want to destroy what players have already mad

[acoustic horizon]

How big can a structure be?

[upbeat barn]

48x48

        ]
    }
}

Do you know what could be causing my trees not to generate?

[leaden furnace]

Is the scatter_chance default 100 when not specified ? never tried(in the feature_rule)

[acoustic horizon]

I could try it

[leaden furnace]

With one iteration if you choose 50 as scatter chance, there will be 1/2 chance to spawn one tree per chunk

more iteration equal more trees if the scatter is successful (if I'm getting it right)

[acoustic horizon]

"distribution": {
      "scatter_chance": 100,
      "iterations": 1,
      "x": 0,
      "y": 0,
      "z": 0
    }

This still doesn't work

[leaden furnace]

Here's the one I'm using for my ice_plains trees, will send a picture to show what it does
{ "format_version": "1.13.0", "minecraft:feature_rules": { "description": { "identifier": "aquila:frozentree_feature_rule", "places_feature": "aquila:frozentree_weighted_feature" }, "conditions": { "placement_pass": "first_pass", "minecraft:biome_filter": { "test": "has_biome_tag", "operator": "==", "value": "ice_plains" } }, "distribution": { "iterations": 4, "scatter_chance": 50, "x": { "distribution": "uniform", "extent": [ 0, 16 ] }, "y": "query.heightmap(variable.worldx, variable.worldz) + 0", "z": { "distribution": "uniform", "extent": [ 0, 16 ] } } } }

(when my game will be loaded.. it takes so many times sometimes 😦 )

[acoustic horizon]

I want to generate some gigantic trees

[leaden furnace]

gifantic like how

[acoustic horizon]

Though, they are all smaller than 48x48

[leaden furnace]

I have trees that are 25x35x20

Maple trees

The problem I have it is sometimes they are cut at the edges of the biomes

[acoustic horizon]

This is one of the biggest

or the biggest

[leaden furnace]

that is fine, I have double palm trees bigger than that

[acoustic horizon]

Then why it is not appearing 😠

Minecraft bad terraria better

lol

[leaden furnace]

Ignore the fact I forget to add snow layers in my saved structure 😄 but it is what it does with the feature_rule above

Ice plains are empty usually

[acoustic horizon]

That would probably cut my trees because of the size

All these plains are actually forests, no trees

[leaden furnace]

Yeah 1 iteration is enough due to the size

but you should have at least one tree per chunk imo or it will appear too empty

[acoustic horizon]

I can't even generate one tho

[leaden furnace]

scatter chance 100

[acoustic horizon]

I did try that, not generating any

[leaden furnace]

I think I found out$

It's y =0

Replace y=0 by "y": "query.heightmap(variable.worldx, variable.worldz) + 0",

[acoustic horizon]

ah yes you found it

Lovely

[jolly ember]

Yep ^ . Beat me to it. Might want to remove the block constraints due to the structure being large or it will probably appear supper rarely.

[leaden furnace]

true as there is a lot of grass and they are not air

[acoustic horizon]

well

im in love

as a builder this is the fancier thing I have experienced with addons lmao

[leaden furnace]

Have you filled your structure with structure void(to replace air blocks)

[leaden furnace]

It's so nice 🙂

[acoustic horizon]

yes

I do that by default lol

[acoustic horizon]

Thank you!!

They are getting cut

[leaden furnace]

I am in love with custom trees, and I can relate about the feeling to see my own trees spawning naturally 🙂

[leaden furnace]

It doesn't look like there is biome edges tho.. I have also structures cut as well and some people have posted already about this and there is not much a solution emerging for now(apart replacing the structures with a command blocks always active inside a structure that load a function to spawn the structure and delete the command block) But I don't like this solution even if it works for two reasons:
The structure are not generating as far than the natural generation
Loading a lot of structures with commands create lag(with ghost placing around the structures load for a couple a ticks) while it does not with generation for some reasons

[delicate trench]

whats the structure size

[acoustic horizon]

28x21x30
12x17x12
23x22x28

[acoustic horizon]

Yeah I don’t think I want to make that

World gen only applies to non-generated chunks?

[acoustic horizon]

Unrelated question

[delicate trench]

Yes

[delicate trench]

Have you changed this file at all since you posted it here?

[acoustic horizon]

Yes, here is the updated file:

{
    "format_version": "1.13.0",
    "minecraft:structure_template_feature": {
        "description": {
            "identifier": "kai:forest_tree_variation_3"
        },
        "structure_name": "mystructure:tree_3",
        "adjustment_radius": 16,
        "facing_direction": "random",
        "constraints": {
            "grounded": {}
        }
    }
}

[delicate trench]

Set facing_direction to south for all 3 variations and see if that fixes the cutoffs

[acoustic horizon]

Seems fixed, yes

Having these trees facing the same direction will be quite unfortunate, though. There is no other fix?

[leaden furnace]

I was about to ask as well . Because it requires to create 2 or 3 versions of the structure to have it randomized

[delicate trench]

youd have to make four variations of each structure with different rotations, the facing_direction rotates from the chunk origin, not from the center of the structure

screws with what parts of the structure get cut off and what parts dont

south is the default direction, so you can at least guarantee the rotation acts normal by keeping it at south

[acoustic horizon]

I see

Thank you!

[hasty kelp]

is there an addon that replaces the 1.18 world generation into the old one? Even with just the old mountains, I personally like the old world gen better ngl

[round cosmos]

Thanks, this is great! I figured it out but I'm sure someone else will find it super useful

[steep lintel]

any Hello World example for Cusotm World Generation?

[upbeat barn]

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

[steep lintel]

does it still work?

[leaden furnace]

What is this page

[steep lintel]

i mean custom generation

not custom biome

[upbeat barn]

Everything except Custom Biomes should work

[delicate trench]

Eh, some features didn’t make it to stable

There’s still a conditional list-shaped hole in my heart :(

[upbeat barn]

Chop chop update the wiki

[delicate trench]

Feels like the wiki hasn’t been updated in at least a year

[upbeat barn]

😔

[delicate trench]

The heck’s been happening with the other pages then

[simple pond]

How do you remove small end islands

[zealous sedge]

Making a false air block and then generating it with a column or also a solid block

[simple pond]

have you tried that ?

[zealous sedge]

Ye

It's what works for me

[simple pond]

Omg then you're the first one to found a way

[zealous sedge]

What?

[simple pond]

Yeah

[upbeat barn]

Isnt this common knowledge though lol

[zealous sedge]

Ye

XD

[upbeat barn]

Afaik the method doesnt work with everything...chorus flowers, mineshafts

[simple pond]

i mean small end islands

[zealous sedge]

The chorus flowers yes

[simple pond]

people have been struggling to remove it for agess

[zealous sedge]

But you have to generate another block below that is not end stone

[simple pond]

No lol,look up all the attempts of people trying to remove small end islands with features

[upbeat barn]

Its technically common knowledge that this method exists

But see my previous comment, the method doesnt work with some features

[zealous sedge]

Because if you try to eliminate any of those things with normal air, the only thing it does is make them reappear again.

[simple pond]

@olive ridge ever thought of this ?

[upbeat barn]

at this point just wait for Mojang to resume work on custom world gen

[zealous sedge]

If I have so many limitations

[simple pond]

If you don't mind can you...forward us the method you use ? We really need it for a huge project we're doing and end island is what we are most struggling with 😭

[zealous sedge]

Alr

Give me a minute

@simple pond

Just put an air texture

[olive ridge]

yes, but that isn't always effective

[simple pond]

Still better than nothing

[olive ridge]

check the code

[simple pond]

Oh

[simple pond]

is there truly no other method ?

[ashen shadow]

How do you load a custom BP structure with the sructure command?

do you need to specify what pack somewhere?

[upbeat barn]

Just do /structure load <structure id>

[ashen shadow]

I tries, it says it doesn't recognize the structure 🫤
The id is just the name of the file ? I can't find an id defined elsewhere is the .mcstructure

[upbeat barn]

Needs to be namespace: id

[ashen shadow]

I tries...
I'll try again later

or does the structure need to have the namespace in the name?

[leaden furnace]

Do you want to generate your structures with features or just with commands, because it's different, this channel is for world generation

[ashen shadow]

just command blocks for now

but I still think here is better than #1067869288859447416 for this particular case

[leaden furnace]

There is people really good at commands there, they basically know everything. And what Smokey told you is what you need to do. If you are still struggling, post in the commands general

[junior orbit]

@upbeat barn hellooo, any idea what i could do about my command blocks only executing when within a certain range? I would like to spawn my command blocks, as structures, using feature rules, and have the command blocks automatically spawn these large structures, using the /structures load command.
And it is doing all of that! But only executing when within range, and not on start.

I know there has been a lot of talk about the command block generating large structs. Not sure if ive missed a solution. Is there anything i can do at all about the chunk generation for command blocks?

[upbeat barn]

Nothing you can do really. Until Mojang gives Bedrock functional Jigsaw blocks you're stuck with this

[abstract carbon]

Can I make custom dimensions?

[upbeat barn]

No

[abstract carbon]

Is it broken?

[leaden furnace]

It never existed, it was only fake dimension

Make a custom portal texture, a custom portal frame, detect when the player are inside the portal and teleport them somewhere else (like really high in the sky) in a custom terrain/builds trees or whatever you have made

[abstract carbon]

Oh okay but can we make dimensions by using existing features?

[abstract carbon]

That's my plan but I don't know how to make the dimensions that's all

But can I modify the vanilla dimensions?

[leaden furnace]

It has been made for the end, it looks hard, regarding the amount of post about it, but yes. If I would make something like that II would rather change the world height and generate new terrain/structures biome related to make variations more easily, and generate all of that at y 400

In the overworld

[abstract carbon]

I found this video where he make own biomes by using an empty world

https://youtu.be/Y0yB3WCgqiU?si=8fdaqY6M0Pi8LO1q

[abstract carbon]

Damn, that was so many works

[leaden furnace]

I have pranked my kids with the Warden portal, I told them that in the preview there is a new item to lit the portal, then they crafted it and lit the portal, then they were teleported in a special terrain I have made, it was so funny 😄

Just an illusion 😉

[abstract carbon]

Nice but I hope the next update will be that we can make our own dimensions and biomes

[leaden furnace]

At least the biome would be nice, and allow us to spawn big structures without having it cut in half...

[simple pond]

why not the end ? The end is more convienient

[leaden furnace]

Because I like the end, custom dimension for me is a new one, or a fake new one.(I have made just a few modification in the end to have it less boring but that's it). I would not say more convenient as you need to delete everything and create new stuff. In the overworld there is multiple biome tags while there is only one for the end if I'm good. Making a fake dimension in the overworld easier. Just my opinion tho

[simple pond]

How would you handle the big tree forests tho ?

[leaden furnace]

What do you mean by that?

[simple pond]

it's impossible to delete features like that via world voiding

[leaden furnace]

It's not meant to be deleted.
You just create new terrain at y400 in the overworld, 1 million block away from the spawn(where nobody will get in survival), you don't have to delete anything, generate new terrain biome related at y400 like you would have generated in the end, but as the overworld has multiple bipme tag, customisations will be easier imo

[steep lintel]

Custom World Generation on Custom Server lmao

[leaden furnace]

Insane!

[bitter fog]

guys, does the structure export button for andriod pack work anymore

I used em and well when u press the button a file exports but the file is empty

[thin fox]

Does anyone know any methods for detecting the player's current biome? (without editing player.json)

[bitter fog]

i think script api has something for that but idrk

[thin fox]

It's not stable 😔

[bitter fog]

ohh

sry then i cant help you there 😬

[scenic kraken]

only beta, so no

[jolly ember]

Well... you can place a specific block via features in the bottom bedrock level for each biome and use a block detect command in a function to apply a tag to the player. This is the method I created in order to regain control over custom fogs and particles for my noise biomes while avoiding player file editing. Although anyone else using this method makes it incompatible with my stuff😅 ) . Though I'll admit ZQ and SC would be a weird mix. Maybe use y:-63 instead of y:-64...

[thin fox]

Yeah that's the method I've been using for my Ashlands biome, but it doesn't always seem to detect correctly

[jolly ember]

Hmm. Not sure then. I have placement issues with this system, but I alleviated most of the command detect issues by pairing it with a scoreboard counter.

[misty pivot]

What about entities? Like a dummy one? They can detect what biome they're in.

[misty pivot]

Wait nvm, don't think it would work in your situation.

[thin fox]

i don't think it would either

[thin fox]

I don't want to edit any vanilla entities

[simple pond]

is there a way to fully the remove little smol end islands ?

[pale elk]

i got a error on my custom ore feature, it said "The feature uses the feature type 'minecraft:ore_feature', which is considered internal and thus not compatible with this engine version of the game."

[upbeat barn]

Set you min engine version to 1,20,60 in the manifest file

[round cosmos]

Is the trapdoor orientation in structure features bug still not fixed?

Dang looks like that's the case

[sly forge]

…i might have figured out a way to more accurately place noise biomes

instead of just a terrain map and a biome map using the same noise algorithm

why not use the terrain generation algorithm to determine what is a mountain biome, what is a regular biome, and what is an ocean biome?

and then from there, use two completely different generation algorithms, one for heat and one for humidity to control those?

i had been thinking all wrong about biomes should determine what the terrain looks like, i should have thought the other way around

i need to try this out sometime

in this way i can also have these biomes seem a little more random in their placement

omg i can also use a scoreboard randomizer function that only triggers on first join and i can use this value to control each of the different maps

i can produce seeds higher than the 64-bit limit-

this is insane

why didn’t i think of this before

its not that complicated

as long as i can get the terrain algorithm where i want it, i’ll be set

[steep lintel]

You may see some clounds in the distance

idk if i should post it here lmao, since its not vanilla bp

[delicate trench]

It’s fine honestly, this chats dead anyway lol

[delicate trench]

This is just the system Henrik Kniberg explained in his terrain video from 2 yrs ago

[steep lintel]

well i got some cool clift when i was playing with proximity and 3 layers of perlin noise

[minor girder]

What are you using to generate this? Custom server?

[steep lintel]

ya, i am learning world gen with custom server for now, bc its faster to change it bc it doesn't saves loeaded chunks

[minor girder]

awesome! what custom server software are you using?

[steep lintel]

custom custom server software

like i made my own lmao

i can share a github repo with you if you want

[minor girder]

whoa 👀

Sure, I'd love to check it out!

That's honestly so impressive

[steep lintel]

if you want to try it let me know that setup is a bit not user friendly lmao

https://github.com/bedrock-apis/bedrock-server

[sly forge]

ah well i have a problem

molang loses precision at 16777216

if i lower the offset to 100k i can only use 160 seeds for the terrain generation

which is obviously a problem

and i don’t know how i can combat this

@olive ridge youre great at worldgen, think you can help me with this custom seed problem?

[upbeat barn]

Ideally q.noise would differ base on seed

[olive ridge]

the game is unplayable out there anyways

[sly forge]

ideally yes

but unfortunately it only queries the perlin noise map, not the seed

[sly forge]

im offsetting the terrain at steps of 100k

this was the original max offset

but with that 16M limit it screws me over

i need help figuring out how to layer terrain

[olive ridge]

how would you even get to that number without an unplayable ammount of jitter

[sly forge]

like how biomes in minecraft have both a temperature and humidity map

[olive ridge]

it's just 2 perlin functions

[sly forge]

it was going to offset the terrain so you wouldn’t see the same hill or mountain every time

[sly forge]

im not sure how to layer terrain maps because theyre essentially different

the biome maps have the ability to tell what block to place based on certain number parameters, you cant really do that with a heightmap

[olive ridge]

I'm really not sure what you're asking

[sly forge]

how to layer them to determine how the terrain generates

[olive ridge]

layer what

[sly forge]

i can only have up to 160 terrain shapes at this point

[sly forge]

terrain algorithms

[olive ridge]

the climate maps determine the biome types, which determine the terrain shape

[sly forge]

im doing things the opposite way around because it seems more viable

[olive ridge]

don't

[sly forge]

its harder to map the terrain properly if i base everything off of biomes

[olive ridge]

you can get around that by running stuff for every column instead of every chunk

[sly forge]

isn’t that how custom terrain works in the first place?

[olive ridge]

yes, but there are ways to do it per chunk

[sly forge]

i don’t think ive ever done that

[olive ridge]

you can probably approximate the position of the border based on the value and derivative of the perlin noise

[sly forge]

the main reason it’s difficult is because id need to find a way for everything to transition properly

[sly forge]

oh god not calculus 💀

[olive ridge]

if you're using voronoi noise, you can approximate the edge distance and use that as a blending term

then you would also calculate the other biome and blend between the heights

[sly forge]

i don’t want to use voronoi tho, i want to make a different system

i don’t want ppl to think im ripping off ur own 💀

[olive ridge]

voronoi is just the way to do it

[sly forge]

and how would i go about this anyways

[olive ridge]

voronoi can give you the 2 closest biomes to a given point, so you just have to run the terrain for both then blend or blend the parameters

[sly forge]

i don’t know how to blend different y values

[olive ridge]

just lerp between the two

[sly forge]

i don’t even know how the lerp function works

[olive ridge]

it's literally just lerp(a,b,k) = a*(1-k) + b*k

which linearly blends between the two values based on k, which is the blend weight

so if k = 0, then you get a, and it k = 1, you get b

and for anything in the middle, you get something between a and b

[sly forge]

and how is k determined? how would i get the block values for each biome?

i don’t understand this stuff

[olive ridge]

k would be the distance to the edge of the biome

probably multiplied by some constant and clamped from 0 to 1

[sly forge]

k would be the distance in terms of what exactly?

[olive ridge]

blocks

on the x/z plane

[delicate trench]

Magnitude of the vector

[olive ridge]

no

technically, it isn't a true distance

[delicate trench]

He’s not using voronoi?

Oh whoops he’s not

[olive ridge]

voronoi edge distance generally isn't accurate

[sly forge]

but then where does the 0 and 1 come from

[olive ridge]

x and (1-x)

it's just to make sure it doesn't exceed a or b

[sly forge]

the point being if it were the case of it being in blocks, K would go over 1

[sly forge]

i was planning on using perlin but apparently my terrain is limited to 160 options

which is waaaay too low

[delicate trench]

You’re trying to blend biomes together?

[sly forge]

i want to hit the old bedrock edition limit MINIMUM

[sly forge]

chungus is trying to explain voronoi to me

[olive ridge]

https://www.desmos.com/calculator/p0o37sa0z4

[delicate trench]

I’m confused, are you or are you not going to use voronoi?

[sly forge]

i was going to have terrain determine what biomes can or cannot generate (i.e. at certain values you could get plains, mountains, or oceans)

[olive ridge]

https://en.wikipedia.org/wiki/Voronoi_diagram

[sly forge]

ok thats just…not necessarily good for certain biomes

[olive ridge]

it's for blending between biomes

and you don't have to blend the height

ideally, you would blend the generation settings

[sly forge]

and how would i do that 💀

[olive ridge]

lerp(biomeA.noise_scale, biomeB.noise_scale, clamp(k,0,1))

then you would do that for all of your settings

[sly forge]

and what is the noise scale?

the algorithm used itself?

[olive ridge]

no, that would be some setting you use to generate your heightmap

it could be color or anything else

[sly forge]

so basically for one biome maybe the number in front of it that determines where it generates like 96 and the lower biome was 73, this would be the noise scale?

[olive ridge]

noise scale was just an example

it isn't meant to mean anything

[sly forge]

…

then can you fully explain what you mean by “noise scale”

[olive ridge]

it means nothing

it's just an example of a property of your biome

[sly forge]

that doesn’t make much sense

because that could literally mean the algorithm itself for that biome

[delicate trench]

Could you think of it like temperature, humidity, etc.?

[olive ridge]

that's basically what it means

use the same algorithm for all of you biomes

[sly forge]

but then it would be like 4 or 5 different numbers per biome which im not sure math.lerp allows

[olive ridge]

then just change the parameters of the algorithm

[olive ridge]

you lerp each one individually

[sly forge]

so for a certain biome i could multiply the entire formula by 0.9 to get a lower y variation as a noise scale?

[olive ridge]

wouldn't reccomend it, but yes

start by writing your generator on shadertoy, then port to mc

[sly forge]

but if i wanted over a certain amount of biomes like, say, 50, wouldn’t that be a crazy rabbit hole of making each biome lerp to every other biome manually?

[olive ridge]

no

but also yes for other reasons

[delicate trench]

Each biome should really just be its own arrangement of the parameters you choose

[sly forge]

so lets say i want to make a desert dunes biome

[olive ridge]

like I said, write your code in a real language, then convert to molang

[sly forge]

heat would be between 0.85 and 0.95, humidity would be between 0 and 0.05, erosion would be between 0.1 and 0.2, continentalness would be between 0.15 and 0.25, and one other arbitrary value would be between 0.6 and 0.7

how would i blend this with a flat plains biome with all values set to 0.5?

[delicate trench]

Like chungus said, lerp the values

[sly forge]

thats a lot of values to lerp

if the plains biome had one value slightly different wouldn’t i have had to lerp the values 10 times?

[delicate trench]

No?

[sly forge]

??

seriously im stupid

[delicate trench]

You lerp the same values everytime

[sly forge]

oh

[delicate trench]

That’s how blending works

[sly forge]

so heat to heat

humidity to humidity

etc

[delicate trench]

Yes

Each biome gets assigned a “threshold” of values. You blend the values and the biome changes when those values cross over the threshold.

The blending just ensures the terrain remains continuous throughout the change

[sly forge]

but still, how would i get “k”

especially since it wont always be between 0 and 1

[delicate trench]

👆

[sly forge]

that doesn’t tell me how to get it

that explains only what it is

[olive ridge]

@sly forge https://www.shadertoy.com/view/lXSXRm

[delicate trench]

Oh I never knew shadertoy supported structs, now I feel stupid lmao

[sly forge]

i don’t understand anything thats going on here.

i understand molang more than anything thats there

ik what “vec” is (vector)

i know what for, int, float, if, else if, and return are

everything else i don’t understand and the comments don’t help

and what operator is “+=“

[olive ridge]

x += a is just x = x + a

it's supported by almost every language

[sly forge]

how can a variable equal more than itself

[olive ridge]

hash just generates a random seeded vector

[olive ridge]

it's an assignemnt

it's just add something to x, then store the result back to x

[sly forge]

oh ok

[olive ridge]

and x++ is just x += 1 is just x = x + 1

[sly forge]

where is the biomes[0] coming from

[delicate trench]

That's calling the first element in the biomes array

[sly forge]

then whats the other 3 being used for

as well as the other 3 numbers in each part of the array

[delicate trench]

Look further down in the code

The other 3 elements are rgb values that correspond to each biome

[sly forge]

there’s nothing telling what theyre assigned to

[delicate trench]

b1 = biomes[int(r*4.0)]

b2 = biomes[int(r*4.0)]

[sly forge]

again i don’t see anything that says that r, b, and g are the other 3 rows in the array

[delicate trench]

They're not part of the array, they're part of the Biome struct

And the Biome structs are what's filling the array

[sly forge]

then where are the biomes 0, 1, 2, and 3 coming from? i don’t see any code relating to what they are

and in the entire thing all i see references to is 0

Bigchungus can correct me if I'm wrong, but I think those are more for in-game use. Like in a practical scenario, that's where you'd assign values to different biomes so you know where to generate biome-specific features.

In the shader, the rgb values matter more for visuals

well im trying to understand how to set up voronoi as a whole

[delicate trench]

Just download bigchungus' pack for that ¯_(ツ)_/¯

Flip through the code and see how it works

[sly forge]

that wont explain anything

itll tell me what’s being used, not what it does

im guessing k is shown as 0_to_1 here?

and where even is his pack in the first place

[simple pond]

you're in the team -.-

just look at Chungus code jeez.

[sly forge]

looking at it now and it’s confusing asf to read

found it

…where is v.rx even coming from

welp since the only thing that’s happening is me getting confused i guess i’ll use the octaves for the seed

@upbeat barn Hey! Im curious what method you'd recommend for this "pool" look. (blue blocks)

I tried to create a basic rule, that places scatter feature. (yellow blocks), at world height + -1. So i have them in the ground correctly.
But the patches don't look very good.

I tried to replace the scatter feature, with a vegetation rule. But the vegetation rule, wasnt being placed in the ground, at -1.

Any suggestions?
Are we able to place vegetation features in the ground?

Or is there a nicer way, to get that cluster look, in the ground, with scatter feature?

Feature rule:

Scatter:

Last I tried placing blobs together I used https://wiki.bedrock.dev/world-generation/surface-builder.html something like this. Vegetation patch places a square though which is unsavoury. You got any other recomenndeations @muted ether ?

[muted ether]

Yeah, but you can kinda stack vegetation patches for a quick-and-dirty solution. Just place multiple smaller ones.

i have nice vegetation patches

sry 1 sec

@muted ether i dont mind these, but the problem is that, they arent able to be placed in ground?

id like to use the same clover patch shapes, like above.

but simpl;y have them in the ground, as single blocks. Like the "pool" reference above

[junior orbit]

with this exact rule, i simply swap scatter featuyre, for vegetation. but the vegatation is placed above the ground

not under

[muted ether]

Invisible tree trunks with ground blocks is one idea. Noise-based scatter features are another. Blob scatter features also would work.

Thank you! Got it looking well!

New question! 😄
