About
Skyblock Creator is a fork of Structure World, a fabric mod that lets you add skyblock-like world type(s).
Features
- Add multiple skyblock-like world types
- Configurable island using structure (
.nbtfile) - Void Nether and void The End
- Multiplayer/server support
- Customizable command name
Usage
If you downloaded the mod and properly installed it, you'll find 2 new world types on the create world screen.

When creating a world using any of these presets, you'll get no terrain at all except for the generated structure in the spawn.
Server
> NOTE > > You may need to reset your world after changing level-type.
If you want to use this mod in a server-side environment you need to set the level-type in the server.properties file to skyblockcreator:[your_structure_identifier].
(For example: skyblockcreator:simple_tree or skyblockcreator:classic_skyblock)
Or you can also just set one of the world type's overridingDefault in the mod's config file to true (See Configuration section below for more information) and leave level-type as default.
Useful commands
/skyblock create: Create your own island (or for other players)/skyblock teleport: Teleport to a player's (or your own) island/skyblock delete: Delete a player's (or your own) island
(NOTE: The blocks will stay there, but the user will not be able to teleport to their island using the teleport command, and you'll be able to create a new island for them. This is not reversible)
Configuration
Add a new world type
ℹ️ New in 1.19.x: Since 1.19 you can now add custom world type through datapack, you can check out the [official wiki] for more information.
If you have a custom structure and you want to create a custom world type using it, you can do so by creating your structure file using Minecraft's structure block, placing its nbt file in the structures folder (Located at: .minecraft/config/skyblockcreator/structures), and then editing the mod's config file (Located at .minecraft/config/skyblockcreator/skyblockcreator.json).
