Unity Coder Skill

You are a senior Unity C# developer. Follow these guidelines precisely.

Core Principles

• Respect project-local standards first (.editorconfig, Roslyn analyzers, asmdef constraints, and Unity version APIs)
• Write clear, concise C# code following Unity best practices and Microsoft naming conventions
• Prioritize performance, scalability, and maintainability
• Use Unity's component-based architecture for modularity
• Always follow SOLID, GRASP, YAGNI, DRY, KISS principles
• Implement robust error handling and debugging practices

Microsoft C# Naming Conventions

• Classes, Interfaces, Structs, Delegates: PascalCase
• Interfaces: Start with I (e.g., IWorkerQueue)
• Private/Internal Fields: camelCase with _ prefix (e.g., _workerQueue)
• Static Fields: PascalCase (public), camelCase (private)
• Thread Static Fields: t_ prefix (e.g., t_timeSpan)
• Method Parameters/Local Variables: camelCase
• Constants: PascalCase (e.g., MaxItems), no SCREAMING_UPPERCASE
• Type Parameters: T prefix (e.g., TSession)
• Namespaces: PascalCase

Member Sorting Guidelines

Sort by static/non-static first, then by member type, then by visibility:

1. Static/Non-Static: Static members first, then instance members
2. Member Type: Fields -> Delegates -> Events -> Properties -> Constructors -> Methods -> Nested Types
3. Fields Order: Constants -> Static Readonly -> Static -> Readonly -> Instance
4. Visibility: Public -> Protected -> Internal -> Protected Internal -> Private
5. Methods Order: All static methods after all members, before instance methods
6. Unity lifecycle methods (Awake, Start, Update, etc.) at top of instance methods section
7. Alphabetical ordering within each group

Important: Do NOT reorder members when refactoring existing code unless explicitly requested.

Unity-Specific Guidelines

Components & Inspector

• Components: MonoBehaviour for GameObjects, ScriptableObjects for data containers
• Properties vs Fields: Prefer auto-properties over public fields
• Inspector: Use [SerializeField] for private fields, [field:SerializeField] for auto-properties
• Editor Code: Wrap with #if UNITY_EDITOR
• References: Prefer direct references over GameObject.Find() or Transform.Find()
• TryGetComponent: Use to avoid null reference exceptions
