ChunkHopper 1.21.11

ChunkHopper Plugin - Latest Fixes & Optimizations 1. Server Crash Fix · Issue: Server would freeze (20 second hang) when items spawned in a chunk with a ChunkHopper · Cause: The onItemSpawn method was too heavy, scanning ALL tile entities in the chunk every time · Fix: · Added cache system to prevent constant chunk scanning · Rate limiting (max 10 items per second per chunk) · Try-catch blocks to prevent errors from crashing the server 2. Compilation Errors Fixed · isCancelled() doesn't exist in TileState → replaced with isPlaced() · NullPointerException with getCommand("ch") → added check if command exists · Removed unused imports (lines 42-44) · Added economy null check for depositPlayer() 3. Performance Optimizations · Cache System: Tracks which chunks have a ChunkHopper · ConcurrentHashMap: Thread-safe collections to prevent concurrency issues · Rate Limiting: Prevents items from being processed too quickly · Reduced Chunk Scanning: Only scans chunks when placing/breaking, not for every item 4. Dupe Protection · processedItems cache: Tracks which items have already been processed · Items are only processed once · Cache automatically cleans up every 2 minutes 5. Item Disappearance Fix · Issue: Items would disappear when the hopper was full · Fix: Now checks if items can fit using addItem() · If hopper is full: items stay on the ground · If hopper is partially full: only the fitting amount is collected 6. Improved Error Handling · All events have try-catch blocks · Errors are logged but won't crash the server anymore · Better null value checks 7. Faster Item Transfer · Optimization for ALL hoppers (not just ChunkHoppers) · Less heavy operations in the main thread 8. Cache Management · Automatic cache cleanup every 2 minutes · Removes invalid/broken hoppers from cache · Prevents memory leaks Current Status The plugin now: · No longer crashes · No compilation errors · Better performance than before · No more disappearing items · No more duping · Smoother item collection This version is safe to use on your server!
