BackPackSSS

🛡️ Industrial-Grade Stability Thread-Safe Snapshot Saving: Implemented inventory snapshotting. Inventory contents are now cloned on the Main Thread before being passed to asynchronous SQLite tasks, completely eliminating data corruption or item loss during high-activity movement. BackpackHolder (Custom Identifier): Introduced a custom InventoryHolder specifically for backpacks. This ensures 100% accurate identification of backpack inventories, preventing any accidental interaction with Chests, Barrels, or other GUI menus. Force-Save on Disconnect: Added a fallback mechanism to trigger an immediate save during PlayerQuitEvent (Quit, Kick, or Timeout), ensuring player data is never rolled back even during erratic disconnects. ⚡ Performance & Anti-Exploit SQLite Database Integration: Migrated from slow YAML file storage to a professional SQLite engine. All I/O operations are performed asynchronously, maintaining a stable 20 TPS even with a high player count. Anti-Dupe Opening Lock: Integrated a logic lock and a 0.1s cooldown for opening backpacks to prevent common duplication glitches caused by rapid interaction spam. Shift + Click Support: Fully enabled Shift-Click functionality, allowing users to quickly deposit or withdraw items without tedious drag-and-drop operations. 🚫 Custom Restrictions & Rules (Configurable) Nesting Prevention: Strictly blocks players from placing a backpack inside another backpack to prevent infinite storage loops. Carriage Limits: Added a configurable max-backpacks limit (default: 1) to control the number of backpacks a single player can carry. Intelligent Item Filtering: Introduced a toggleable filter to block Armor, Weapons, Tools, and Books from being stored in backpacks, ensuring balanced gameplay and reduced NBT complexity. 🎨 Compatibility & Graphics 1.21.x Hybrid Compatibility: Optimized the file structure to support both legacy 1.21 rendering and the new 1.21.4+ Item Components system. Namespace Standardization: Unified all assets under the backpacks namespace, resolving "black & purple" texture errors and ensuring smooth 3D model rendering. Tiered Crafting Progression: Refined recipes to require the previous tier's backpack as the core ingredient, creating a more rewarding upgrade path.
