About One Survival Island
From ModrinthDatapack that creates a Single Survival Island in an Infinite Ocean World
One Island
You spawn on a small survival island, in the middle of an endless ocean world. There are no other islands. Additionally, the oceans generate deeper (this is primarily to stop an issue in vanilla where land generates in ocean biomes).
Island Size Changing/Removing (Datapack ONLY)
Inside the data/one_island/worldgen/density_function/spawn.json file, there are two numbers you can change to adjust the size of the islands. I've left comments in this file for clarification on instructions, but you can modify your island to be thousands of blocks long, or even remove it entirely!
Compatibility
There is a high chance this will be compatible with most packs, although the worldgen may be overridden to this island generation.
Gameplay Notes
- The ocean is deeper than normal.
- There are no Mushroom Islands.
- There will likely be no dripstone caves/deep dark, as those only generate inland.
- Sometimes your island may be overtaken by a river, you can always make a new world to test out a better seed.
I may update this in the future to have these cave biomes though if this becomes popular/requested.
Future Plans
- Allow the mod version to be configured in-game, rather than needing to configure the data pack.
