BattleGround Worldborder (Blue Zone)

BattleGround WorldBorder

This mod implements the Blue Zone system from Battlegrounds in Minecraft.

It provides a configurable shrinking zone system that can be used for battle royale, PvP, minigames, and custom maps.

_Note: Blue Zone applies equally to all single-player maps (bug)_

Features

• Configurable Blue Zone
• Custom zone center
• Smoothly change the zone radius
• Schedule multiple zone stages
• Damage players outside the zone
• Enable or disable the zone at any time
• Supports up to 100 scheduled stages
• Works on custom maps and multiplayer servers

Commands

/zone center – _Sets the center of the Blue Zone._

Example: /zone center 0 0

/zone damage – _Sets the damage dealt to players outside the Blue Zone._

Example: /zone damage 5
This deals 5 damage every second to players outside the zone.

/zone disable – _Disables the Blue Zone._

While disabled, the zone does not progress and players do not take zone damage.

/zone enable – _Enables the Blue Zone._

/zone reset – _Resets all scheduled Blue Zone stages._

/zone set – _Changes the Blue Zone radius over a specified amount of time._

Example: /zone set 50 30
The zone smoothly shrinks or expands to a radius of 50 blocks over 30 seconds.

/zone setnext – _Schedules a Blue Zone stage._

Example:

• /zone setnext 1 500 30 300
• /zone setnext 2 200 50 200

In this example:

1. The zone waits 300 seconds.
2. The zone changes to a radius of 500 blocks over 30 seconds.
3. The zone then waits 200 seconds.
4. The zone changes to a radius of 200 blocks over 50 seconds.

The __ value can be set from 1 to 100.

Example Battle Royale Setup

You can create a simple shrinking-zone sequence like this:

• /zone enable
• /zone center 0 0
• /zone damage 5
• /zone setnext 1 500 30 300
• /zone setnext 2 300 45 240
• /zone setnext 3 150 60 180
• /zone setnext 4 50 45 120

This creates a sequence of progressively smaller Blue Zone stages.

Requirements

• Minecraft 1.21.1
• NeoForge 21.1.x
