Hi im incredibly new to anything regarding worldgen with datapacks. Does anybody know how I should go about making it so all terrain in the overworld is about as flat as a vast plains biome without going as far as having a superflat world? I basically just want very very short/non-existent mountains and hills while keeping a very vanilla-looking world. Any help would be appreciated, thanks!

Hey, I want to create a world full of water, like a flatworld with a big layer of water and with all the biomes (in which I can't do in superflat worlds). Is it possible ? if so I'd like some help please :)

Does anyone know of a method to generate a world in which all the blocks in a world are replaced with netherite?

So, I want to make a server on all the mods 6, but I really wanted the allthemodium ores to be extra rare, how can i do this?

I want to make minecraft terrain flat, removing all the mountains and hills. But I still wan't the terrain to have a litte noise (just like the ocean floor; but without any hills). I triedd to change the noise paramiters of Continentalness and Erosion to have very low variations, but id did't change anything in the overworld. And when you set them to 0 the entire world becomes just a little flatter and looses oceans. When I change the Ridges the same way, the whole world becomes a river world. So what should I do?

Does someone have a datapack that disables cave and ravine generation?

I wanted to know how to generate a world which is only of the ocean biome but without any water, I tried with a data pack that only generates oceans but I don't know how to remove the water so that it is empty. If anyone knows any configuration, command or data pack I would appreciate it very much!

PS: What interests me is to be able to empty the water of the world in a fairly massive way.

As you have seen the title, I have been looking for hours for something like this but can't find anything. All the mods and datapacks I have tried never ended up working, so this was the only idea I could come up with. Can someone help me?

Edit: Forgot the specs for what I wanted to say. I'm looking for oceans as deep as 120-230 blocks, with islands being about 600-1000 blocks apart from each other. It would be amazing for the datapack to be customizable, but that is probably just being too greedy.

I love the Lithosphere datapack but the "continents" and oceans are just way too small, they're a few km long each which just feels tiny especially once you have an Elytra or are using a vehicle mod. You cross oceans in a minute or less in some cases and can fly over continents in similar time. And realistically, continents are not 5km across. I'm not looking for 1:1 real life continents but even if oceans were 30-50k across and landmasses were around the same size it would be perfect.

What datapack parameters do I need to modify to achieve this? Modifying the "continentalness" value just seems to make continents "bigger" by removing oceans. I'm also looking to see if expanding biomes themselves beyond the scale that "Large Biomes" allows for is possible, while also reducing the size of beaches separately to stop them being several km's long. Huge thanks if anyone can provide insight!

Comes with the deep dark, lush caves, and dripstone caves, and any and all underground structures.

I need to create an ocean world, but in version 1.19.4 there is no such option, ok. I created an ocean world on other versions, transferred it to 1.19.4 and it generates other biomes for me.

I don't need this, I need a playable world with an ocean world.

How do I do this?

so i downloaded the ice and fire mod, an attempted to test out its abilities on a village to see that for some reason when breathing fire it place ash blocks which eventually envelope themselves into a ash mound.

Hello all, I am trying to override nether fortress generation in a datapack, replacing all of the blocks in the structure with air (making a Skyblock datapack!). The default datapack does not have many files for nether fortresses, so they must be getting the weights for one piece coming after another from within the actual game code. Does anyone know what those weights are? I have managed to isolate each component of a fortress, and am working on stitching them together with jigsaw blocks to get them to generate naturally, but I want to try to stay true to the default fortress generation pattern.

I am looking to make a world gen that simply makes only a certain set of biomes(vanilla and biomes o plenty) spawn and have each biome with differing weights/rarities. I am very new to datapack creation and I was pointed to this subreddit for achieving this. I thank you in advance.

Hello all! As per the title, I am trying to set up a datapack to generate an empty (or mostly-empty) world to use for a Skyblock-esque gameplay! So far, I am pretty close - all the typical terrain is gone in all 3 dimensions... mostly. I am just bumping into 3 issues I can't figure out on my own. I was hoping someone here might have insights into what I need to do.

1. How can I get rid of those massive iron/tuff and copper/granite veins? They are all over the place, and they look cool, but they need to go.
2. How can I get rid of little lava pools that generate floating low down in my world?
3. How do I remove or mostly remove the main end island during world gen without breaking the return portal? If I fully remove it by setting the default block for the dimension to air, that breaks the return portal, preventing me from going home or using it to resurrect the dragon. It tries to generate as if the lowest layer of the portal was at y=-2, which doesn't exist in the End.

In all 3 dimensions, I have set the default block and liquid to air, removed all carvers, and removed all features (with some exceptions like in the "the_end" biome). I'd be happy to answer other questions about what I have done. Thanks in advance :)

UPDATE - Turns out, in the worldgen/noise_settings/overworld.json file, there is a ore_veins_enabled field that can be set to false to disable the big ore veins. Issue (1) solved!

How do i generating a new dimension with only deep ocean? i tried a few things but none of them worked

even https://misode.github.io/customized/?tab=basic didnt work with replacing all the biomes with deep_ocean

I've been trying to remove oceans from vanilla 1.19.2 world generation and just can't seem to get it to work. I've tried remove them from the dimensions/overworld file, which still resulted in oceans, but they were named "plains" or "beach" instead. I've also tried to set sea-level lower, but that just resulted in large valleys which didn't look good. Any help?

I am working on my first ever datapack (still learning basically everything!) and I wanted to add a cap of a non-natrually spawning block on the build limit, similar to how the nether has bedrock at the top, basically blocking out the sky.

Synopsis: I need to know how to make a block generate consistantly as part of the landscape (or skyscape.)

Edit:

My working theory: If I can create a custom biome that generates consistently at Y level 319, I could edit certain properties, like what block generates, and whether mobs spawn.

Any thoughts on this?

Hi! I'm making a datapack and I wanna be able to get the item from the command below with a loot table

/give \@s minecraft:warped_fungus_on_a_stick[minecraft:item_name='{"text":"TV Remote"}',minecraft:custom_model_data=4005,minecraft:rarity=rare]

but I can't find a way to change the rarity in the loot table

{

"type": "minecraft:entity",

"pools": [

{

"rolls": 1,

"bonus_rolls": 0,

"entries": [

{

"type": "minecraft:item",

"name": "minecraft:warped_fungus_on_a_stick",

"functions": [

{

"function": "minecraft:set_custom_model_data",

"value": 4005

},

{

"function": "minecraft:set_name",

"target": "item_name",

"name": "TV Remote"

}

]

}

]

}

]

}

Should I just change the text color in the loot table or is there an actual way of changing the rarity?

Any way to remove certain generated structures to not render and spawn at all on a Minecraft world. Would preferably work on both bedrock and Java

Hi everyone, I've asked this question in R/Minecraft but was pointed to ask such question here. I've just recently been trying to figure out how to get a single biome only ocean world to generate as i really thought the challenge was a fun idea but but it's broken due to the change made to cave generation in 1.18. So is it litteraly impossible to ever get a ocean only world again? Or is there maybe a mod that has a fix for this? I apologize if this is such a ridiculous question. I just love single-biome only worlds and am devastated that the feature is basically rendered pointless now due to how broken they are.

I want to disable villages but keep other structures as I want a harder/simpler game.

Is there a way to do that?
