About this Mod

Personal Borders

Fabric mod that adds player-specific world borders using LuckPerms permissions.
Two players with different borders

Features

  • Separate world borders for each player and each dimension
  • Prevent players, players' projectiles, and players' pets from crossing the border
  • Updated in real-time when permissions are changed

Configuration

Personal Borders looks for next four permission nodes in LuckPerms:

  • personal-borders: default world border, if dimension-specific border is not set
  • personal-borders.overworld: overworld border
  • personal-borders.the_nether: nether border
  • personal-borders.the_end: end border

Parameters of the border are stored in the permission node as context values that are similar to Vanilla world border command:

  • center.x, center.z: coordinates of the border center
  • distance: size of the border (diameter)
  • warning.distance: distance from the border at which the player's screen starts to tint red
  • damage.amount: damage dealt to the player per second per block when outside the border
  • damage.buffer: distance from the border at which the player starts taking damage

This mod requires Fabric API and LuckPerms to be installed on the server.
