ForgeNeoForgeServer-side onlyGNU General Public License v3.0 or laterOpen source1.19.4 – 1.21.4

What it does

The mod changes world generation through Minecraft's datapack system, with the aim of predefining the central continent, seed, temperature gradient and similar settings. Its author describes it as still in alpha, so breaking changes are expected between builds. Only the server needs it, and players join without installing anything. Forge and NeoForge files cover 1.19.4 – 1.21.4, with 0.1 for 1.20.6 as the latest Forge build and 1.0-rc3 for 1.21.4 as the latest NeoForge build. The project is open source under the GNU General Public License v3.0 or later.

Key features

  1. Position-based world rules

    Block-level rules let the mod alter how the world behaves depending on where a block sits.

  2. Predefined world layout

    Settings such as the central continent, seed and temperature gradient can be fixed in advance.

  3. Datapack foundation

    Functions are built on the datapack system, which opens possibilities for both developers and players.

What the author says

ATTENTION: This mod is still in an alpha stage of development. Breaking changes and instability should be expected. Did deserts spawning right next to snowy mountains ever feel weird to you? Or is it the fact that the climate in Minecraft is pseudo-random, so you can never know where you may find snow in the first…
