ECS Architecture

When to Use

Use this skill when:

• Building a game or simulation with many interactive objects
• Refactoring object-oriented game code for better performance
• Implementing data-oriented design patterns
• Creating scalable game systems with complex interactions

Core Principles

1. Composition over Inheritance: Entities are composed of components, not class hierarchies
2. Data Locality: Components store data; systems process data in contiguous memory
3. Separation of Concerns: Components = data, Systems = logic, Entities = IDs
4. Type Safety: Leverage TypeScript for compile-time guarantees
5. Performance: Cache-friendly iteration over components
