About this Mod
!
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.
