BattleGround Worldborder (Blue Zone)
by Legon__
BattleGround Worldborder adds a configurable shrinking Blue Zone to NeoForge, used to run battle royale PvP minigames and custom maps.
What it does
Blue Zone applies to single-player maps as well as multiplayer servers, and it works on custom maps. Players outside the zone take 5 damage each second, and zone progress can be disabled so the boundary stays in place. Zone stages are defined with commands such as zone set and zone setnext, which fix the center, the radius and the time each stage takes. A single stage can move the radius from 50 blocks to 30 over 30 seconds, and up to 100 scheduled stages can be chained into one sequence.
The mod is meant for battle royale and PvP minigames built on custom maps, where the playable area has to contract on a timetable. Its client and server environment means the server and every player need the mod. The code is released under the Apache License 2.0, but the project is not open source. NeoForge 1.0.0 for 1.21.1 is the only published build, dated 2026-09-07, and the first release was 2026-09-04.
Key features
Scheduled zone stages
Up to 100 stages can be queued, each with its own center, radius and duration, so a match can shrink in steps.
Smooth radius changes
A zone can shrink or expand gradually to a new radius over a set number of seconds, instead of jumping.
Custom zone center
The center of each stage can be placed at any coordinate, which lets a map shift the play area away from spawn.
Damage outside the zone
Players outside the boundary take damage each second, and the amount is configurable.
Zone map overlay
A map of the Blue Zone can be shown so players can see the current boundary.

Use cases
Battle royale maps
A map author can schedule a sequence of progressively smaller zones so the play area contracts over a match.
Custom PvP minigames
Minigames that need a boundary can set the center and radius by command and skip the zone progress.
Who it’s for: Map makers and server owners who run battle royale or PvP minigames on NeoForge 1.21.1 need a configurable zone system with commands to schedule its stages.
