🛡️ Border — High-Performance Custom World Border Engine
Border is a next-generation, high-performance world border management plugin engineered for modern Minecraft servers (Paper / Purpur 1.20+).
Unlike standard worldborder solutions, Border introduces custom animated shader textures, realistic collision pushback physics, and a built-in HTTP daemon that automatically delivers the client resource pack upon join — completely eliminating the need for third-party hosting or external CDNs.
✨ Key Features
- 🎨 Custom Shader Textures — Render animated honeycomb shader barriers with smooth wave effects or seamlessly switch back to classic vanilla worldborder walls.
- ⚡ Dynamic In-Game Controls — Smoothly shrink, expand, set radius, relocate center coordinates over time, and toggle geometric shapes (
circlevs.square) in real time. - 📦 Built-in Resource Pack Server — Integrated lightweight HTTP micro-server automatically streams
pack.zipto connecting players with zero external setup. - 🛡️ Boundary Physics & Knockback — Configurable pushback velocity force, strict anti-exit barrier prevention, particle bursts, sound cues, and actionbar alerts.
- 🌈 Universal Color & Text Engine — Full native support for Hex codes (
#0088FF), Adventure MiniMessage tags, RGB, and legacy formatting (&c,&l) across standing, shrinking, and expanding states. - 📊 PlaceholderAPI Integration — Comprehensive real-time placeholders for your scoreboard, tab list, actionbar, and bossbars.
- 🚀 Zero Tick Overhead — Highly optimized asynchronous routines designed for high-traffic networks, SMP events, and competitive UHC tournaments.
