A lightweight, robust, and highly optimized Nether Portal plugin for PocketMine-MP 5 that accurately recreates vanilla Bedrock and Java Nether portal behavior while maintaining excellent server performance and stability.

• 🔗 Bidirectional Portal Linking
  Seamlessly links Overworld and Nether portals. Entering any registered portal block teleports players back to the exact paired location.

• 🏠 Fallback Lobby Support
  Unlinked Nether portals safely return players to a configurable fallback world.

• ⚡ Asynchronous Chunk Generation
  Automatically pre-generates surrounding destination chunks asynchronously before teleportation for maximum stability.

• 💾 Asynchronous SQLite Database
  All database operations run in AsyncTasks to avoid TPS drops and main-thread lag.

• 🧵 Thread-Safe PM5 Architecture
  Designed specifically for PocketMine-MP 5 multi-threading requirements using safe serialization techniques.

• 🧱 Advanced 3D Portal Detection
  Robust 3x3x3 scanning detects complete portal structures even when players enter off-center.

• ⏳ Teleport Delay & Cooldown System
  Fully configurable portal warmup delays and cooldown timers to prevent teleport loops.

• 🌍 Multi-World Support
  Easily supports survival servers using separate Overworld, Nether, and lobby worlds.

Lighting a valid Obsidian frame automatically creates a Nether Portal structure.

Players standing inside the portal trigger a configurable teleport timer.

Destination chunks are asynchronously loaded and generated before teleportation occurs.

• Existing linked portals are reused automatically.
• Missing links generate new paired portals safely.

Broken or destroyed portals are automatically removed from cache and database asynchronously.

AZNetherPortal is designed with performance as the highest priority:

• Minimal TPS impact
• Fully asynchronous database handling
• Safe teleportation logic
• Optimized chunk preparation
• Lightweight caching system
• PM5 thread-safe design

• PocketMine-MP 5.x
• PHP 8.1+
