Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21.9–1.21.10Newest
Minecraft 1.21.6–1.21.8
Minecraft 1.21.5
Minecraft 1.21.2–1.21.4
Minecraft 1.21.1

⬇ Download for 1.21.9–1.21.10 ⬇ Download for 1.21.6–1.21.8 ⬇ Download for 1.21.5 ⬇ Download for 1.21.2–1.21.4 ⬇ Download for 1.21.1

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

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

Example: Example of LuckPerms settings

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