# Unity Project Rules

## Environment
- Unity 2022.3 LTS
- C# 9.0
- New Input System (Unity.InputSystem)
- Universal Render Pipeline (URP)

## Coding Conventions
- Follow Microsoft C# coding conventions
- Use PascalCase for public members, camelCase for private
- Always add [SerializeField] attribute to private Unity fields
- Use [Header] and [Tooltip] attributes for Inspector documentation

## Unity-specific Rules
- Prefer GetComponent in Awake(), not Start() or Update()
- Never use Find() or FindObjectOfType() in Update()
- Use coroutines or async/await for time-based operations
- Prefer ScriptableObjects for data configuration
