Description
OneBlock
Survive on a regenerating block in the void. Break it to get new resources, expand, and face random events. Supports solo and multiplayer with per-player islands.
Now supports Minecraft 1.21.11 (Fabric) and all new content.
Installation
Singleplayer:
- Install Fabric Loader and Fabric API.
- Put OneBlock-<version>.jar in your mods folder.
- Create a world with level-type=oneblock:oneblock.
Multiplayer:
- Set up a Fabric server with Fabric API and OneBlock in mods.
- In server.properties:
- level-type=oneblock:oneblock
- Add oneblock:oneblock_multiplayer to initial-enabled-packs for per-player islands.
- (Optional) Add void/end/nether packs as needed with oneblock\:oneblock_void_nether, oneblock\:oneblock_void_end, or oneblock\:oneblock_no_island.
- New: Set oneblock.multiplayerIslandSpacing=<blocks> to control island distance before first world creation.
Recent Changes
- Configurable multiplayer island spacing via server.properties (set before world creation)
- Cross-player OneBlock fixes:
- Owner name and break count shown when breaking another's OneBlock
- Progression, hardness, and stats follow owner if enabled
- Respawn bug fixed: No more "Loading terrain" hang

Tip: If islands are too close/far, delete the world and set spacing before restarting.
