Water World

by millennIumAMbiguity

With Water World installed, the land is mostly submerged, and the sea level of the world is raised to Y=127 by a datapack that works on the server.

What it does

Sea level sits at Y=127 under this datapack, so the land of a freshly generated world ends up underwater. Biomes are adjusted so they match the new sea level, and a simple custom spawn structure is placed close to the spawn point to give players a safe place to start. Survival strategies change, since swimming and exploring the ocean become the main tasks, and ruins are built to be reached from the sea.

Water World is a datapack, so it works on a server without a loader mod. Server owners choose it as a method to transform the world, and it can be combined with other datapacks. The mod is available for 1.20 – 1.21.4 on Fabric, Forge, NeoForge and Quilt, with the latest file built for 1.21.4. Only the server needs it; players can join without installing anything. It is released under the MIT License and is open source.

Key features

  1. Raised sea level

    The sea level is set to Y=127, so the whole terrain sits under a water-filled surface.

  2. Spawn structure

    A small custom structure near spawn gives players a dry starting point in the flooded world.

  3. Adjusted biomes

    Biomes are modified to match the higher sea level, which keeps the generated terrain consistent.

  4. Underwater building

    Underwater cities and islands can be built in the flooded environment, with aquatic survival challenges.
