How to make a OneBlock server

1What's in the OneBlock template

What the OneBlock template sets up

Server	Paper 26.2, build 129
Java	25
Memory	3 GB, 2.2 GB of it for Java
Rules	Normal difficulty, PvP off, up to 20 players
Plugin	Multiverse-Core 5.8.1 · BSD-3-Clause
Plugin	OneBlock 1.6.3 · MIT
Checked	28 Sep 2026: created and started on Playkeeper 0.4.2, ready in 13 seconds with every plugin enabled

2Make the OneBlock world first

OneBlock doesn't make its islands on its own: the plugin's README has an operator create a world with its generator, then mark where the first block goes. In the Console, then in the game:

# In the Console: a world made with OneBlock's generator
mv create OneBlock normal -g Oneblock
# In the game, as an operator, standing in that world
/ob set 500

/ob set 500 puts the first block where you stand and spaces islands 500 blocks apart; without a number they're 100 apart.

3How players start and team up

• /ob takes a player to their own island, and a bar shows how far they are through the level.
• /ob invite Alex asks a friend to share the island; they type /ob accept.
• /ob listlvl lists the levels, from the first grass block to the End.

4Defaults to look at

From the config OneBlock wrote on the test server:

• Protection is off, so players can walk onto each other's islands. /ob protection true keeps them home.
• Nobody is sent to the OneBlock world on joining. /ob autojoin true starts players on their island as they arrive in it.
• Islands are laid out in a circle, and the Nether is allowed. Both are in plugins/Oneblock/config.yml.

5Open it in one click

Playkeeper runs your server on a VPS you rent. Install it with one command:

1. 1

   Open the template below

   Your dashboard shows Multiverse-Core and OneBlock before anything installs.

2. 2

   Create and start it

   It runs in 3 GB: a single block at a time is light work.

3. 3

   Run the two setup commands

   Then send friends an invite link and tell them to type /ob.

6The same server by hand, with Docker

# OneBlock: Paper 26.2 on Java 25, 3 GB in all
docker run -d --name oneblock -p 25565:25565 \
  --memory 3G --memory-swap 3G \
  -e EULA=TRUE -e TYPE=PAPER -e VERSION=26.2 -e MEMORY=2304M -e USE_AIKAR_FLAGS=TRUE \
  -e DIFFICULTY=normal -e PVP=false -e MAX_PLAYERS=20 \
  -e MODRINTH_PROJECTS=multiverse-core,oneblock_bukkit \
  -v oneblock-data:/data itzg/minecraft-server:java25

Open TCP 25565 in your provider's firewall.
