Follow the specific instructions in that example file for syntax, structure, and best practices

Each example file contains:
- Instructions: Overview and usage guidelines
- Syntax: API syntax and parameters
- Examples: Complete code examples with explanations
- Reference: Links to official documentation
Generate C++ code following Cocos2d-x v4 conventions:
- Use USING_NS_CC; for namespace
- Use CREATE_FUNC() macro for create functions
- Follow Cocos2d-x naming conventions
- Include proper error handling
- Use smart pointers where appropriate
Reference the official documentation:
- Official manual: https://docs.cocos.com/cocos2d-x/v4/manual/zh/
- API reference: Check api/ directory for detailed API documentation
- Examples: Check examples/ directory for code examples
Use templates when creating new projects:

Core Concepts

Node System

Node: Base class for all display objects
Scene: Root node of the scene graph
Sprite: Image display node
Label: Text display node
Node hierarchy: Parent-child relationships

Coordinate System

Origin at bottom-left (OpenGL style)
Anchor point for positioning
Local and world coordinates

Action System

Action: Base class for node transformations
Sequence: Chain multiple actions
Spawn: Run actions simultaneously
Repeat: Repeat actions multiple times
Ease: Apply easing functions

Scene Management

Scene transitions
Scene lifecycle (onEnter, onExit)
Director for scene management

Input Handling

Touch events (single and multi-touch)
Mouse events
Keyboard events
Event dispatcher system

Platform Support

Cocos2d-x v4 supports:

Desktop: Windows, macOS, Linux
Mobile: Android, iOS
Web: (via Cocos Creator)

Important Notes

Version: This skill covers Cocos2d-x v4 specifically
Language: C++ is the primary development language
Build System: CMake is required for building projects
Platform: Ensure platform-specific dependencies are installed
Examples: All code examples use C++ syntax
Memory Management: Cocos2d-x uses reference counting, be careful with retain/release cycles
Coordinate System: Uses OpenGL-style coordinates (origin at bottom-left)
Thread Safety: Most Cocos2d-x operations must be performed on the main thread
