About this Mod
Skyblock Creator
A fabric mod that lets you add skyblock-like world type(s).
NOTE
This mod development is on halt due to personal reasons, this mod requires much more time to maintain compared to my other mods.
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.
(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).
Here is how the default config file should look like:
{
"structureWorldConfigs": [
{
"structureIdentifier": "simple_tree",
"biomeIdentifier": "minecraft:forest",
"structureOffset": [
-2,
0,
-2
],
"playerSpawnOffset": [

}
],
"createPlatformPermissionLevel": 0,
"teleportToPlatformPermissionLevel": 0,
"platformDistanceRadius": 1000,
"commandName": "skyblock",

}
[1.19.x Only] Here is what a world type (called world_preset internally) file looks like:
{
"dimensions": {
"minecraft:overworld": {
"type": "minecraft:overworld",
"generator": {
"type": "skyblockcreator:structure_chunk_generator",
"biome_source": {
"type": "minecraft:fixed",
"biome": "minecraft:plains"
},
"dimension": "overworld",
"playerSpawnOffset": [0, 3, 0],
"structureOffset": [-3, 0, -1],
"structure": "classic_skyblock",
"fillmentBlock": "minecraft:air",
"enableTopBedrock": false,
"enableBottomBedrock": false,
"isBedrockFlat": false
}
},
"minecraft:the_end": {
"type": "minecraft:the_end",
"generator": {
"type": "minecraft:noise",
"biome_source": {
"type": "minecraft:the_end"
},
"settings": "minecraft:end",
"dimension": "the_end"
}
},
"minecraft:the_nether": {
"type": "minecraft:the_nether",
"generator": {
"type": "minecraft:noise",
"biome_source": {
"type": "minecraft:multi_noise",
"preset": "minecraft:nether"
},
"settings": "minecraft:nether",
"dimension": "the_nether"
}
}
}
}
Create new dimension
In Minecraft version 1.16 or newer, anyone can create a new dimension via datapacks.
When using this mod, you can make your custom dimensions work as structure worlds and even have multiple structure worlds in the same server.
Here is what a dimension file should look like:
{
"generator": {
"type": "skyblockcreator:structure_chunk_generator",
"structure": "simple_tree",
"structureOffset": [-2, 0, -2],
"playerSpawnOffset": [0, 8, 0],
"biome_source": {
"type": "minecraft:fixed",
"biome": "minecraft:plains"
}
},
"type": "skyblockcreator:test_dimension_type"
}
More information about custom dimensions in 1.16+ can be found in the official wiki.
Override default dimension
If you want the structure world generator to always be the main generator in the modpack, you can set the overridingDefault property to true in the mod's config file.
By doing that, all the worlds created by the client will default to the configured world type, and creating a new server will also set the level-type to it.
