Fake World Border

Multiple damage-free, impassable world borders — as many as you want, anywhere you want.

Fake World Border lets you place any number of named, vanilla-looking world borders in every dimension. They look and feel exactly like the real world border — the same animated blue forcefield wall you cannot walk through — but they never deal damage, and there is no red screen tint. Perfect for arenas, adventure maps, protected zones, progression gating, and server events.

Why not just `/worldborder`?

The vanilla world border has three problems this mod solves:

Vanilla border	Fake World Border
Only one border per dimension	Unlimited named borders per dimension
Hurts and kills players outside it	Zero damage, ever
Red vignette tints the screen	No screen tint

Features

🧱 Truly solid — walls use the exact same collision resolution as the vanilla border: players, mobs, boats and minecarts are all stopped cleanly, with no rubber-banding and no tunneling at high speed.
🟦 Vanilla visuals — the familiar scrolling forcefield texture, with the same distance fade and animation as the real border.
🗺️ Per dimension — borders live in the dimension you create them in. Overworld, Nether and End each keep their own list.
💾 Persistent — borders are saved with the world and survive restarts.
🌐 Multiplayer ready — server is the source of truth; borders sync automatically on login, respawn, dimension change, and every command edit.
🇰🇷 Command feedback localized in English and Korean.

Commands (OP level 2)

/fakeborder add <name> <centerX> <centerZ> <size> Create a border (relative ~ ~ coordinates supported)

/fakeborder remove <name> Remove a border (tab-completes existing names)

/fakeborder resize <name> <size> Change a border's size

/fakeborder list List all borders in this dimension

Example — a 64-block arena around you, plus a 16-block pen at spawn:

/fakeborder add arena ~ ~ 64

/fakeborder add pen 0 0 16

Installation

Requires Minecraft 1.20.1 with Forge 47.4.0+. Install on both server and client (the client needs it to render the walls and predict collision smoothly; singleplayer just needs it in your mods folder).

No config file, no dependencies.
