    Superflat has a number of limiting factors which make it not as appealing as if they'd just flatten the world for you, so I took a stab at that.



    Caves and chasms still generate with this simple datapack making the world almost flat. Plants and structures still spawn, too. It's whatever seed you threw in, but a nearly-fixed height. Sadly, a bit of how they coded the Deep Dark with varying elevations means a lot of it happens on the surface, with another biome mere blocks of elevation away.



    I wanted this pack as a way to showcase other projects rather than trying to work on superflat worlds. Having multiple biomes present on a wide expanse unobstructed by mountains or even hills is what I' want for good pics. But if you want a flat world that isn't a superflat, you might be pleased to find that most the resources of the full game are right here. It's also nice that it maintains seeds, so if you want a superflat version of a particular structure layout, you can use this with a world you've already found - though the flat layout may generate more of varying-size structures like villages.



    Images are of a random world started with this pack, except for the last one. That is a single-biome world with this pack - bamboo jungle everywhere.


    It's not Superflat, and it may just be better.


    UPDATE: I have corrected the main issue with ground level spawning as deep dark. It now modifies two parts of the density function.




    --- TECHNICAL INFORMATION ---


    This datapack is marked as incomplete because water doesn't happen for rivers and oceans. Fixing this would likely involve much more in-depth changes that would make it less compatible with other packs, so I am unlikely to work on that unprompted.

    While this pack was made with the current version of Minecraft, it should be compatible as far back as you can use datapacks.


    This pack overrides the density function that determines overworld terrain height. It should be compatible with any pack that does not change the solid terrain generation.

    It'd be great to see a little more compatibility with oceans/water.

    You might want to check out my new upload, Builder's Plate. It's a superflat checkerboard, sized up to give a good build area and modified to have lower river/ocean depths.

    I agree. Unfortunately, that would require editing the main noise file to make ground lower in water biomes specifically. That ould make it not work with a lot of other datapacks and mods, because a lot of world generation is piled in that one spot.



    I'm not entirely sure how PMC would feel about me making a derivative mod for that, but stay tuned - I'm pretty sure I could mock one up with part of the coding I did for the checkerboard datapack. Worst that happens is they tell me not to do that again and take it down.



    As an aside, the current version of this and my checkerboard pack are compatible, but the water still isn't happening. Once I get the water fixed, it's something that would have to be manually added into any alternate world generation you're interested in running with a flat world.
