Biome Rings

This mod aims to provide a json file to force the generation of a biome or a list of biomes in a specified range of the overworld center.

This mod DO NOT changes the terrain, it only forces the biome settings, what affects mob spawnings, structure generations and natural enviroment (trees, grass, flowers, etc).

It only works on new generations, this mod do not overwrites already existing chunks.

Note that this mod was only tested in vanilla 1.21.1, and probably has little to no compatiblity with any other custom biomes/terrain generation mods.

I (the author) have no plans of updating this mod any further than bugfixes, optimization and/or config file QoL. If you want to add features or compatibilities you are strongly incentivated to fork/copy the repository and do your version.

How to use / What it can do

The config file is located in ~/config/biomerings.json

Note that the config file will be auto-generated with an example code in the config.

the parameters in the config are:

Key Description Default
roundness The deformation of the rings, where 1.0 is perfectly circular 0.7
noise The repetition of the "stripes" of biome when there are many in the same range, a bigger number means more visible "stripes" 0.4
global_blacklist The list of biomes that are not meant to be overrided [...]
rules The list of rules for the generation [...]

You can force a list of biomes to appear at certain range of the overworld center, settings minimum and maximum distances and pool weigth.

For example, you can set generation to be plains from 0 to 300, pool desert, badlands and wooded_badlands between 300 and 600, and pool forest and dark_forest between 600 and 900 blocks of distance of the world center.

Example of config file 
{
  "roundness": 0.4,
  "noise": 0.5,
  "global_blacklist": [
    "minecraft:ocean",
    "minecraft:deep_ocean",
    "minecraft:warm_ocean",
    "minecraft:lukewarm_ocean",
    "minecraft:cold_ocean",
    "minecraft:deep_cold_ocean",
    "minecraft:beach",
    "minecraft:river",
    "minecraft:mushroom_fields"
  ],
  "rules": [
    {
      "biome_id": "minecraft:plains",
      "min_distance": 0.0,
      "max_distance": 300.0,
      "probability": 1.0
    },
    {
      "biome_id": "minecraft:desert",
      "min_distance": 300.0,
      "max_distance": 600.0,
      "probability": 0.4
    },
    {
      "biome_id": "minecraft:badlands",
      "min_distance": 300.0,
      "max_distance": 600.0,
      "probability": 0.3
    },
    {
      "biome_id": "minecraft:wooded_badlands",
      "min_distance": 300.0,
      "max_distance": 600.0,
      "probability": 0.3
    },
    {
      "biome_id": "minecraft:forest",
      "min_distance": 600.0,
      "max_distance": 900.0,
      "probability": 0.7
    },
    {
      "biome_id": "minecraft:dark_forest",
      "min_distance": 600.0,
      "max_distance": 900.0,
      "probability": 0.3
    }
  ]
}

You can also overwrite unwanted biomes at range of the worldspawn by setting then as whitelist of whatever you feel like, for example here i overwrite snow biomes with plains and meadow. (also frozen rivers as rivers and etc)
