About this project
What does Saros Worldborder Customizer add?

Saros Worldborder Customizer gives server admins and singleplayer users full control over the look of the Minecraft world border. Change its color, make it invisible, adjust transparency, set a custom warning color, or let it pulse with animated flair — all in real time, synced instantly to every connected player, and saved across server restarts.

Custom Border Color 🎨
- Set any color using RGB values (0–255 per channel).
/saros_worldborder color <r> <g> <b>- Example:
/saros_worldborder color 255 128 0→ orange border.
Hide / Show 👻
- Make the world border completely invisible with a single command.
/saros_worldborder hide— border disappears entirely./saros_worldborder show— border becomes visible again.
Opacity Control 🔆
- Adjust the transparency of the border independently of its color.
/saros_worldborder opacity <0-255>— 0 = fully transparent, 255 = fully opaque.
Warning Color ⚠️
- Define a separate color that activates automatically when a player steps inside the border's warning distance.
/saros_worldborder warningcolor <r> <g> <b>- Works alongside Minecraft's built-in warning distance setting.
Pulse Animation 💫
- Animate the border so it smoothly pulses between the main color and a secondary color.
/saros_worldborder pulse <r> <g> <b> <speed 1-10>— speed 1 is slow, 10 is fast./saros_worldborder pulse off— disables the animation.
Instant Multiplayer Sync 🌐
- Every change is broadcast to all online players the moment the command is executed.
- Newly joining players automatically receive the current state.
Persistent Storage 🔄
- All settings are saved to the world folder (
wbcustomizer_state.json) and restored after every server restart. - Per-world: different worlds can have different border configurations.
- All settings are saved to the world folder (
Permission System 🔒
- On multiplayer servers: OP level 2 required.
- In singleplayer: all commands are available by default.
