Interaction System Module (UPM)

A lightweight, production-ready interaction system for Unity. Entirely camera-agnostic and input-agnostic, it allows you to build flexible gameplay interactions using a clean, event-driven architecture with zero external dependencies.

🚀 Key Features

• Flexible Architecture: Supports Component-based, ScriptableObject-based, and Hybrid wrapper actions. Mix and match based on your state persistence requirements.
• Mixed Discovery: Automatically scans, sorts, and lists both components and ScriptableObjects sitting on the same interactable target.
• Event-Driven Lifecycle: Rich C# and UnityEvents for discovery, selection tracking, execution, and focus loss—perfect for driving your custom UI, audio, or animation states.
• Camera-Agnostic Raycasting: Built-in decoupled raycast detection with customizable LayerMask filtering. Works out of the box with First-Person, Third-Person, or Top-down viewports.
• Extremely Lightweight: Completely standalone. No forced dependencies on specific UI frameworks, physics setups, or inventory systems. Clean code that integrates seamlessly into your existing codebase.
• No package dependant: completely self contained.
