Sky Archipelago adds a new floating-islands world generation type for Minecraft 1.21.1, with configurable island shapes, height distribution, ocean layer options, and structure placement rules and much more!

While intended for sky island world generation, it is more than capable of creating ocean worlds with islands spanning far from each other. What world you create, is all up to you!

The mod currently only support NeoForge for 1.21.1, as it was built towards Create Aeronautics airship gameplay.

How do I get the Sky Archipelago world to generate? First set the level-type in the server.properties file to

level-type=sky_archipelago\:sky_islands

Under the /config folder (after the server has ran once) Open sky_archipelago-common.toml and paste the values. (Can be made easy via the Export Dedicated button that will copy your preset to your clipboard and you can paste it directly into the file, or via in-game export command /skyarchipelago preset export_dedicated )

What can you currently do with the mod?

As of the 1.0.0 release update you can do the following;

- A new world generation type **Sky Island** + Customize configuration
- Set the island spawning density
- Set the spacing of cluster islands
- Set island sizing mode
- RANDOM = Give min/max value and the terrain generator will roll the dice for each island
- SPECIFIC = Allows setting of small, medium and large island sizes (each min/max and % weight to spawn)
- Island Y spawning range (min/max for where islands are allowed to spawn)
- Island Y spawning brackets
- Low/mid/high bands that you assign the weights for where islands should spawn more or less
- Set whether ocean is enabled or void enabled
- Set ocean block type water or lava

Some advanced configurations available
- Island archetype toggles and weighting
- Classic islands (A default island shape)
- Bowl/Crater
- Terrace
- A toggle to relax the structure spawning rules. (As the mod provides its own structure spawning logic, to try and place structures better on islands)

Preset management - What are presets?

Presets is the makeup of all the configuration that you can save and share with others. If you found your perfect configuration and you want to share it with others, a preset lets you do exactly that.

- Dedicated Preset Menu
- Save/Load/Delete Presets
- Sharing of presets with others via pure-text (JSON)

And finally 3 in-game commands that can only be currently used by OP users.
- `/skyarchipelago preset create <name> [description]` Description is optional
- `/skyarchipelago preset overwrite <name> [description]`
- `/skyarchipelago preset export` (gives you that configuration text you can paste)

And the plan is to add more configuration in the future as well.

-----------------

What does this not provide just now?

Currently the mod does not have any fancy ocean biome logic, so its just a fill of water. Islands do not come with rivers/lakes currently but are planned in the next update to come.

While survival is possible, this was intended for creative-mode for now as of 1.0.0 and will be tailored towards survival-mode as a follow-up release later.

Underground biomes are not fully supported, they will spawn as normal islands with biome data applied to them. (Plans are in place for a cool way to integrate them)
