OpenPaC BlueMap – NeoForge Remap

This mod integrates Open Parties and Claims (OpenPaC) with BlueMap to display land claims on your web maps in real-time.

---

🚀 Major Improvements from Original

This fork includes significant enhancements over the original Fabric version:

⚡ Real-Time Updates

• Event-driven syncing using OpenPaC's IClaimsManagerListenerAPI
• Immediate claim updates – no more waiting 10 minutes for changes to appear
• Live chunk change detection with:
  • onChunkChange

🔧 Platform Migration

• Migrated to NeoForge 1.21.1 (from Fabric)
• Updated dependencies for the latest Minecraft version
• Server-prefixed JAR naming for easy identification

🛡️ Critical Bug Fixes

• Ghost chunk elimination – fixed issue where unclaimed chunks remained visible on BlueMap
• Cache-first architecture – prevents stale data from OpenPaC API
• Memory leak prevention – eliminated OutOfMemoryError crashes
• Thread-safe operations – using ConcurrentHashMap and synchronized collections

🎯 Performance Optimizations

• UUID-based marker identification for consistent tracking
• Incremental per-player updates instead of full map rebuilds
• Efficient chunk caching system
• Reduced update intervals (5-minute fallback vs. 10-minute)
