One Big Island
Java mod listed for Minecraft 1.19–26.x. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
A datapack that changes the world to generate one big island at spawn.
Effects of the datapack
- Size of the island is around 1000 blocks across, bigger or smaller depending on the seed.
- Hills and mountain biomes are greatly increased (lower erosion value)
- Rivers often split the island up into smaller islands near it's edge
- Because the map is so small, biomes and structures are not guaranteed and unsuitable for 100% play throughs
Compatibility
Should work with other world generation mods.
Notes
This is a fork of the One Surival Island by Klinbee.
Plan to test newer versions of minecraft and add them to the filter.
