Simple Inventory + Json Save System

This asset provides a complete, high-performance, and production-ready inventory system that integrates seamlessly into any FPS, RPG, or survival game.

It is built on a clean, event-driven architecture that is easy to understand and extend, focusing on flexibility and performance.

⭐ Core Features

• Full Inventory & Hotbar UI: Separate, fully functional panels for the main bag and a quick-select hotbar.
• Intuitive Drag-and-Drop: Supports both "click-and-drag" and "click-to-grab, click-to-drop" item management.
• Stack Splitting: Hold 'Shift' while clicking or dragging to easily split item stacks.
• Dynamic Tooltips: A clean, responsive tooltip system that automatically displays item names and descriptions on hover.
• Smart Tooltip Positioning: The tooltip intelligently flips to display above or below the cursor based on its position on the screen, never going off-screen.
• Hotbar Selection: Full hotbar support with 1-6 keys and mouse wheel scrolling, complete with a customizable outline for the selected slot.
• World Interaction: Easily drop items (Q / Shift+Q) into the world from your hotbar or any inventory slot.
• Item Pickups: Includes scripts for physical item prefabs that can be picked up from the ground, with "Hotbar-first" priority logic.

🚀 Technical & Workflow Features

• Powerful ScriptableObject Database: Forget the Resources folder! Manage all your items from a single ItemDatabase ScriptableObject. This gives you full control and is more efficient.
• Automatic Database Builder: Includes a custom editor script with a "Find All Items" button. Just create your item .asset files anywhere in your project, click the button, and your database is instantly updated.
• Robust JSON Saving: Automatically saves and loads the player's entire inventory (main bag and hotbar) on quit/start using JSON.
• Performance Optimized: The "dragged item icon" and "tooltip" run on a separate, dedicated canvas to prevent costly UI rebuilding on the main inventory panel, ensuring high and stable FPS.
• Clean & Commented Code: All scripts are fully commented (in English) for easy understanding and modification.

🎮 Genre & Customization

• Genre-Ready: Perfect for Survival Games, RPGs, FPS Shooters, and any project needing robust item management.
• Easy to Customize: The UI prefabs are clean and can be easily re-skinned to match your game's art style. The event-driven logic (OnInventoryChanged) makes it simple to hook in your own systems (e.g., "play sound on pickup").
