LevelBorder – Multiplayer

Expand your world as you level up!

LevelBorder is a lightweight Minecraft datapack that adjusts the world border dynamically based on the combined levels of all players. Perfect for multiplayer servers or singleplayer worlds where progression affects exploration.

Features

• LevelBorder system for single- and multiplayer worlds

• World border scales based on combined player levels

• Border grows 2 blocks per level → 1 block in each direction

• Does not shrink on player death or enchanting

• Border only grows after the previous highest total level is reached

• Border is synced through all dimensions

• Supports player join/leave without breaking the border

• Known limitation: After a server restart, the border is recalculated using only the levels of currently online players. This will be addressed in a future update and is automatically corrected once all players rejoin.

• Sets worldspawn on 0, 64, 0

• Displays player levels in the tab list

• Fully compatible with vanilla singleplayer & multiplayer

Tips / Notes

• To avoid digging through stone with your bare hands you either have to generate a few seeds until you spawn ontop of a tree or set the worldborder manually with /set worldborder - - (or use /xp add -- levels to widen your border :)

• Since no mobs can spawn outside the border your best guess is to dig down and hope for a cave or some ores

• The world border is based on the combined levels of all players – coordinating in multiplayer increases growth faster

• After dying, players must regain lost levels before the border can grow again

• Works seamlessly in singleplayer and multiplayer

• No configuration required – works out-of-the-box

Future Updates

• More customization options for border growth

• Minor improvements and bug fixes
