Custom Biome by Y level minecraft datapack
Posted On: January 16, 2023

I would like anywhere under y28 in the nether to be a custom biome called "nether_depths". I tried using code from the deep dark (since it only spawns deep in the world), but it does not seem to work. How do I change the Y level of biomes?

Answer:

So I ended up figuring it out myself. First, you can set a custom check through use of a density_function with the following value:.


{.


"type": "minecraft:range_choice",.


"input": "minecraft:y",.


"min_inclusive": -32,.


"max_exclusive": 32,.


"when_in_range": 1,.


"when_out_of_range": 0.


}.


In this case, -32 to +32 will pass the check with a value of 1, otherwise the value will be 0.


Then in your corresponding noise_settings file (nether in this case) have depth reference your file (which I called depths): "depth": "minecraft:nether/depths".


Then finally, to add the biome, it's actually not done in noise_settings as I initially expected. It is instead done in the dimension folder. With something to the effect of the following:.


{.


"type": "minecraft:the_nether",.


"generator": {.


"type": "minecraft:noise",.


"settings": "minecraft:nether",.


"biome_source": {.


"type": "minecraft:multi_noise",.


"biomes": [.


{.


"biome": "minecraft:nether_wastes",.


"parameters": {.


"continentalness": 0.0,.


"depth": 0,.


"erosion": 0.0,.


"humidity": 0.0,.


"offset": 0.0,.


"temperature": 0.0,.


"weirdness": 0.0.


}.


},.


{.


"biome": "minecraft:soul_sand_valley",.


"parameters": {.


"continentalness": 0.0,.


"depth": 0,.


"erosion": 0.0,.


"humidity": -0.5,.


"offset": 0.0,.


"temperature": 0.0,.


"weirdness": 0.0.


}.


},.


{.


"biome": "minecraft:crimson_forest",.


"parameters": {.


"continentalness": 0.0,.


"depth": 0,.


"erosion": 0.0,.


"humidity": 0.0,.


"offset": 0.0,.


"temperature": 0.4,.


"weirdness": 0.0.


}.


},.


{.


"biome": "minecraft:warped_forest",.


"parameters": {.


"continentalness": 0.0,.


"depth": 0,.


"erosion": 0.0,.


"humidity": 0.5,.


"offset": 0.375,.


"temperature": 0.0,.


"weirdness": 0.0.


}.


},.


{.


"biome": "minecraft:basalt_deltas",.


"parameters": {.


"continentalness": 0.0,.


"depth": 0,.


"erosion": 0.0,.


"humidity": 0.0,.


"offset": 0.175,.


"temperature": -0.5,.


"weirdness": 0.0.


}.


},.


{.


"biome": "minecraft:nether_depths",.


"parameters": {.


"temperature": -0.6,.


"humidity": 0.0,.


"continentalness": 0.0,.


"erosion": 0.0,.


"weirdness": 0.0,.


"depth": 1,.


"offset": 0.0.


}.


}.


].


}.


}.


}.


Notice how depth is set to 0 for all biomes except my custom one. That means it is most likely out of any other biome to get placed between my specified y values (-32 to +32) as it's depth value matches the value from the check while the others do not.
