A simple open source addon for the Xaero's World Map, which adds drawing visual chunk-based zones on the map for everyone.

IMPORTANT

The mod is currently in alpha, and at the moment it only works locally. It is expected to have a LOT of fundamental changes internally.
Don't expect a savefile to be inter-version compatible as this is a working prototype - there'll be breaking changes soon.
Don't expect support for other Minecraft versions and mod loaders until it is somewhat finished for 1.21.1 NeoForge.


World map view

✨ Features

  • Obviously, integration with the Xaero's World Map
  • Toggle all zones (local only) (not being saved on the map closure currently)
  • Click on a zone to make it active. Click on any empty spot to clear active zone
  • Draw mode (draw a new zone if no active zone is selected or add/erase to/from currently active one). Hold LMB to add, Shift + LMB to erase
  • Edit zone (rename, change border and fill appearance with a palette of 14 predefined colors). The menu could be accessed by the toolbar button and by double-clicking on a zone
  • Delete zone
  • [Planned] Multiplayer support (local only currently)
  • [Planned] Private and public zones (the exact concept is WIP)
