One Block Server Datapack, Own Island per Player
by MD22
One Block Server Datapack gives each player an island of their own when they join a server, starting from a single block in an empty void.
What it does
Each new player who joins gets a personal OneBlock skyblock island, placed automatically in the void. The starting block drops a random item at a set interval, and the drops follow a fixed progression covering wood, stone, food, ore and tools. Everything a player collects can be used to build a supply chain of their own over time, and a configurable spacing setting lets players share one island or receive separate ones.
The mod is a data pack rather than a loader-specific library, so it is installed by placing the .zip into the world's datapacks folder. Servers need it, while players join without installing anything. Fabric API is required on Fabric, and files are published for Fabric and NeoForge, with builds covering 1.18 – 26.3 and the latest Fabric file for 26.2. The code is licensed under the MIT License, and the mod is not open source.
Key features
Own island per player
Each player who joins receives a separate OneBlock island, so progress is kept apart.
Random item drops
The starting block releases a random item every few seconds, giving a steady source of resources.
Shared island option
With spacing set to 0, every player lands on one block and a single item drops per interval.
Setup from the world screen
The .zip is dragged in on the world-creation panel, or placed in the datapacks folder of an existing world.

Skyblock servers
Server owners can run a OneBlock skyblock server where every new player starts with a private island.

Who it’s for: Server owners who want a OneBlock skyblock server with per-player islands, and players who join those servers.

What the author says
You start on a single grass block floating in an empty void. Everything you will ever own falls out of it. A random item drops every few seconds. That is your entire supply chain. Wood, stone, food, ore, tools — whatever the block decides to give you, and nothing else.
