🌍 ShadowBorders
ShadowBorders is a powerful per-dimension world border system for Minecraft Fabric servers. It allows server administrators to configure independent borders in each dimension, block player actions outside the defined area, and enforce custom behavior across portals, collisions, entity interactions, and more.
✅ Features:
- Per-Dimension Borders – Each dimension (Overworld, Nether, End, custom) can have its own unique border size and center.
- Full Vanilla Compatibility – Integrates seamlessly with Minecraft's native world border mechanics.
- Persistent Borders – Borders are saved per dimension and persist across server restarts.
- Teleportation Adjustments – Portals and spawn points are automatically clamped within border limits.
- Safe Zone, Damage, and Warnings – Fully configurable damage behavior and warning zones per dimension.
- Permission-Based Commands – Full support for permission systems like
LuckPerms. - Reloadable Config – Update borders without restarting the server.
