# 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)
