Islands
An overview of the island's mechanics. This guide goes into more detail about the player's experience.
Player Islands
The primary concept behind the SkyBlock genre is the generation of sky islands.
This is facilitated by this plugin through island worlds (see: World Setup)
When a player creates an island using /island create, a cell within the player_island world (configurable) is selected to generate your schematic of the default sky island.
A player can teleport to said island with /island teleport. It is up to you what this island comes with.
You could make it incredibly difficult, standard per the skyblock meta, or some custom variation.
It is recommended to use a plugin like ZNPCsPlus and place an NPC at your spawn that a player can use to make an island for simplicity.
A "cell" within your player_island world contains its own world border, to separate it from other islands and limit the expansion.
This system will respect your world border, and you can expand the amount of islands as needed.
Using the Obelisk, a block with a CustomModelData value (optional), a player can administrate the island to add defenses and view stats, among other configurations.
Faction Islands
When you create a faction, a larger island is created to house your faction, generated in the faction_island world.
This island has access to more defenses and many features from the faction system, as well as needing a separate FAWE schematic to paste (can be the same schematic if you wish).
Faction Islands come with their own separate Obelisk that everyone in the Faction can access and use (if they have the permissions - some regions of the Obelisk are restricted to certain ranks).
