Core Concepts

A quick tour of the ideas that make uxmSkyblock work. Once these click, the rest of the wiki is just detail.

Islands

An island is a region in the island world owned by one player. It has:

  • An owner and a list of members (the team)
  • A protected area centered on the island (the size is set by the size upgrade)
  • A level and points
  • A bank balance, warps, flags, and a border color

Each island lives at its own grid cell; the gap between islands is world.island-distance.

The Island World

The world is generated one of two ways, set by world.generator:

GeneratorResult
voidClassic empty uxmSkyblock — a void world; islands are pasted from a schematic
normalReal, naturally-generated terrain; islands sit on the ground (used by Chunklock)

Each island also owns a private Nether and End plot in their own void worlds, reached through real portals. See nether & end.

Points & Levels

Every block has a point value in block-values.yml:

  • Place a block → its points are added to the island
  • Break a block → its points are removed

When total points cross a threshold in levels.yml, the island levels up. Levels gate upgrades and decide your spot on the leaderboard. See Points & Levels.

Roles & Permissions

Every team member has a role. A role is a bundle of permissions — BLOCK_PLACE, CONTAINER, INVITE, BANK, and so on.

  • Built-in roles (visitor, farmer, member, architect, moderator, owner) are defined in roles.yml.
  • Custom roles can be created per-island at runtime by the owner.
  • The owner always has every permission.

See Roles & Permissions.

Flags

Flags are island-wide toggles that control what happens inside the protected area: PvP, mob spawning, creeper/TNT explosions, fire spread, visitor interaction, and whether visitors are allowed at all. Owners toggle them in /is settings. See Island Flags.

Upgrades

Upgrades improve an island over time. Each has tiers with a level requirement and (optionally) a money cost:

  • team-limit — max members
  • size — protected area size
  • crop-growth — chance to double crops
  • mob-drops — drop multiplier
  • spawner-rates — spawner speed
  • generator — what the cobble generator produces

See Upgrades.

Storage

Island data is saved to SQLite (default, zero setup) or MySQL (for networks). Switch with storage.type. See Database.

The Proxy Layer

Optional. When enabled, islands stay in sync across multiple backend servers behind Velocity/BungeeCord, using a shared MySQL database and Redis. Each island physically lives on one backend, and /is home / /is visit route players to the right server. See Cross-Server Setup.

Modules

uxmSkyblock loads add-on jars from plugins/uxmSkyblock/modules/. A module shares the core's classloader, database, and proxy messaging, and can register its own commands and listeners. See Module System and Chunklock.
