3. 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

4. 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

5. 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

6. Use templates when creating new projects:

   • templates/project-structure.md

     - Standard project structure

   • templates/cmake-config.md

     - CMake configuration examples

Doc mapping (one-to-one with official documentation)

• See examples and API files → https://docs.cocos.com/cocos2d-x/v4/manual/zh/

Core Concepts

Node System

• Scene: Root node of the scene graph
• Sprite: Image display node
• Label: Text display node
• Node hierarchy: Parent-child relationships

Coordinate System

Important Notes

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