🛒 Inventory-Shop System (Unity)

Inventory-Shop System is a fully modular, event-driven framework for managing inventory and shop interactions in Unity. Designed with scalability, responsiveness, and clean architecture in mind, it integrates easily into any Unity project with minimal setup.

✨ Features Overview

📦 Dynamic Inventory Management

• Track item quantities and total weight in real time.
• Dynamically spawn items with randomized values and validation checks.
• Instant UI updates reflecting inventory changes.

🛍️ Interactive Shop System

• Full-featured buy/sell logic with coin, weight, and quantity management.
• Sleek dynamic UI showing item details, prices, and quantity adjustments.
• Edge case handling for insufficient coins or over-capacity purchases.

🔁 Event-Driven Architecture

• Centralized EventService coordinates item logic and UI updates.
• Observer Pattern ensures instant updates across systems (UI, audio, logic).
• Inventory and shop fully decoupled but synchronized through events.

🧱 Modular & Scalable Design

• MVC architecture for clean separation of logic, data, and visuals.
• Reusable generic base classes shared across Inventory and Shop modules.
• ScriptableObjects define item stats (ID, type, rarity, price, weight).

🎮 Enhanced User Experience

• Toggle seamlessly between inventory and shop views using CanvasGroup.
• Real-time feedback via pop-ups, tooltips, and audio cues.
• SoundManager handles contextual SFX using a centralized Singleton service.

💡 Technologies & Architecture

🧩 Design Patterns

• Observer Pattern: Drives UI and logic updates in real-time.
• MVC Pattern: Models store data, Views handle display, and Controllers manage logic.
• Generic Singleton: Lightweight base for managers (Audio, Event, Game).

💻 Advanced C# Techniques

• Used Actions, delegates, and events for cross-system communication.
• Interfaces and generic controllers ensure high reusability and flexibility.
• Created a GenericMonoSingleton<T> to manage global services safely.

🎨 UI/UX Techniques

• Smooth transitions between inventory/shop via UI toggling logic.
• Interactive feedback: pop-ups for weight limits, invalid actions, and purchases.
• Real-time pricing, quantity validation, and error resolution in UI.

🛠️ Development Approach

• Agile & Iterative: Configurable item systems through the Unity Inspector.
• Extensible: Easily add new item types, currencies, or visual panels.
• Optimized: No polling—entire system uses event-driven updates to boost performance.
