Hurtborder

The barrier expands as the player takes damage. (READ THIS!)

How to install?

  2. Create new world and click More/Data Packs
  3. Click Open Pack Folder and place the downloaded .zip file into opened folder.
  4. Create your world.

Functions

  • After starting a game, the world border is set to 1x1 block, centered on the player’s spawn point.
  • Every time the player takes damage, the datapack checks the lost health and increases the border size.
  • Expansion ratio: 1 HP (half a heart) = +0.5 block to the world border.
  • The border always grows evenly in all directions from its center.
  • Don't worry about the datapack incompatibility message, because it has been tested on all versions listed in the version file.
