DimWorldBorder
by elifian
DimWorldBorder lets server administrators set a separate world border for each dimension, so the Overworld, Nether, End and other dimensions no longer share one limit.
What it does
Where most border mods apply one limit to a whole world, DimWorldBorder manages borders per dimension. An administrator can give the Overworld a different size, center and damage setting from the Nether or the End, and any other dimension a server loads can be configured the same way. The mod is built for NeoForge and Fabric and covers the 1.21.1 – 1.21.8 game versions.
Administration runs through a single command, dimworldborder (alias dwb), typed in game or from the server console. Subcommands set the border size, expand or shrink it over a given time, move its center, adjust the damage taken outside it, and configure the warning distance and warning time. A get subcommand reports the current border size.
The mod runs on the server, and players join without installing anything. Install it on a NeoForge or Fabric server running Minecraft 1.21 or later, then configure borders for each dimension in the game. Files are published under All rights reserved, and the source code is publicly available.
Key features
Per-dimension borders
Each dimension, including the Overworld, Nether, End and any other loaded dimension, keeps its own border settings.
Timed resizing
A border can expand or shrink to a new size over a set time rather than changing at once.
Border center and size
The center point and size of each dimension's border are set with separate commands.
Damage and warnings
The damage applied outside the border, the damage buffer and the warning distance and time can each be configured.

Use cases
Who it’s for: Server administrators who run NeoForge or Fabric servers on Minecraft 1.21 and want borders that differ between the Overworld, Nether, End and other dimensions.
