Worlds and the border

The arena, vanilla or custom, the world border and end crystals.

The three worlds

settings:
  lobby-world-name: world
  event-world-name: 'dragonevent_end'
  worldguard-region-name: dragonportal

lobby-world-name holds the spawn players return to. event-world-name is the arena — managed and reset by the plugin. worldguard-region-name is the region containing the entry portal.

Vanilla or custom

custom-world:
  enabled: false
  type: CUSTOM
  folder-name: ""

Mode	Behaviour
`custom-world.enabled: false`	Uses the world named in `event-world-name`
`type: VANILLA`	Same — your existing end world is the arena
`type: CUSTOM`	Uses a world folder placed inside the plugin's folder, named in `folder-name`

A custom world is the better option for anything you have built. Drop the world folder into plugins/uxmDragonEvent/, name it in folder-name, and set the two spawn points with /dragon setcustomspawn and /dragon setdragonspawn.

With a vanilla end, spawn placement is controlled by settings.spawn-type instead — PLATFORM or SURFACE.

The event world gets reset

Whichever mode you use, the plugin resets event-world-name between events. Never point it at a world players build in, and never at your live end. A custom world folder is copied fresh each time, which is exactly what you want for an arena.

The world border

world-border:
  enabled: true
  size: 1000
  center-x: 0
  center-z: -30

size is the diameter in blocks, not the radius. The default is a 1000-block square centred just south of the end spawn — which is where the vanilla end island sits.

The border is what keeps the fight in one place. Without it, a dragon in the vanilla end can drift toward the outer islands and take the event with it.

Set center-x and center-z to your arena's centre if you are using a custom world, and size it to the arena rather than to the dragon's flight range — a border that is too generous is the same as no border.

End crystals

settings:
  delete-end-crystals: true

Removes every end crystal from the event world. On 1.20 and above.

Keep this on for a vanilla end: the crystals heal the dragon, and a fight where players have to break ten pillars first is a much longer fight than your dragon-event-time accounts for. If you want that fight, turn it off and raise the timer.

end-rules.disableCrystalDamage and disableCrystalDestroy control the rest of the crystal behaviour.

Structures

end-rules:
  generateStructures: false

With this off, end cities and other structures do not generate in the event world. Worth keeping off: an arena is not a place for loot, and generating structures for a world that gets reset every event is work the server does not need to do.

Resetting

/dragon reset

Rebuilds the event world now. Normally handled automatically between events; run it by hand if an event ended badly and the arena is in a state you do not want the next one to start in.
