✦ Usage

Open Xaero's World Map and use the region controls:

  1. R opens the region drawing workflow on Xaero's map screen when the player is an operator in creative mode.
  2. Middle mouse click places polygon points while drawing.
  3. T opens the region manager while in normal camera/game view.

Commands are available only to players who are currently in Creative mode.

Hide a region for one player

/region hide <player> <region>

Show a hidden region again

/region visible <player> <region>

Create a point marker

/region createpoint <player> <mode> <iconname> <label> <x> <y> <z>

Arguments:

  • <player>: target player who will see the marker.
  • <mode>: marker lifetime mode.
  • <iconname>: predefined pixel icon. The command suggests available icon names while typing.
  • <label>: text shown under the marker. Use quotes for labels with spaces.
  • <x> <y> <z>: block coordinates for the marker.

Modes:

  • waitenter: the marker disappears for the target player when they enter the marker's chunk.
  • waitcommand: the marker stays until it is removed with /region delpoint.

Delete a point marker

/region delpoint <player> <x> <y> <z>

✦ What It Does

  • Lets operators in creative mode draw freeform polygon regions on Xaero's World Map.
  • Supports named regions, ARGB colors, alpha/opacity, optional categories, predefined icons, and custom PNG icons.
  • Stores all region data on the server and syncs it to every connected client.
  • Restricts create, edit, delete, and icon upload packets on the server to players who are both operators and in creative mode.
  • Respects Xaero's explored-map data so regions only render where the player has already explored the map.
  • Fades newly revealed region portions in over about 1.5 seconds.
  • Shows region entry titles when a player crosses into a region, with optional Traveler's Titles reflection support and an internal fallback overlay.
  • Persists regions and custom icon metadata through world SavedData.
