This mod is an updated and rewritten version of the original Hex Lands mod by superfluke, et. al. It has been rewritten completely for new Minecraft versions.

Features

• Adds two world type presets: "HexLands", and "HexLands (Overworld)". The former which enables hexagonal terrain generation in both the overworld and the nether, the latter which only enables it in the overworld.
• Each hex contains a single biome. Hexes of different types are bordered by walls.
• Automatic compatibility with mods that add biomes to the overworld or other world generation.
• Many options for world customization via data packs.

Configuration (Data Packs - 1.21)

Note: Due to Mojang's changes to world generation, configuration will be different depending on which Minecraft version you are using!

• For 1.19 - 1.21
• For 1.18
• For 1.17
• For 1.16

Worlds are specified by World Presets. HexLands can be customized by adding a new world preset, which uses the hexlands:hexlands chunk generator. The hexlands chunk generator has the following fields:

• type is a string identifying what generator to use. It should be hexlands:hexlands.
• settings is a Noise Settings used by the dimension.
• biome_source is the biome source, as in vanilla. It can be a known preset, such as "minecraft:overworld", or "minecraft:nether", or it can be a JSON object following the vanilla biome source format.
• hex_settings is an object with parameters defining how the hexagonal grid works. It can either be a known preset, which must be one of "hexlands:overworld", "hexlands:nether", or "hexlands:the_end", or it can be an object with the following fields:
  • biome_scale (Default: 8) is the scale at which biomes are sampled to create hexes. Higher values create more random biome layouts.
  • hex_size (Default: 40) is the size of an individual hex.
  • hex_border_threshold (Default: 0.92) is a number between 0 and 1 representing how much of a hex should be covered by the border. Larger values will lead to thinner borders.
  • top_border and bottom_border are both border settings which define how the top and bottom borders of the world are built. The borders between hexes consist of a bottom border, air, and a top border. If not present, this section of the border will consist entirely of air. If present, it must have the following fields:
    • min_height: The minimum height of the border.
    • max_height: The maximum height of the border.
    • state: A block state to generate as the border state. It must be an object with the following fields:
      • Name: The name of the block
      • Properties: An object with any block state properties, such as {"snowy": "false"} that you desire to set

Example

// Below is an example object which can be used in the `generator` field of a world preset.
{
    "type": "hexlands:hexlands",
    "settings": "minecraft:overworld",
    "biome_source": {
      "type": "minecraft:multi_noise",
      "preset": "minecraft:overworld"
    },
    "hex_settings": "hexlands:overworld"
}
