Architecture Overview
The Type Game Engine implements a sophisticated multi-engine architecture with Entity Component System (ECS) design patterns. This page provides a comprehensive overview of the engine's architectural decisions and design patterns.
TypeEngine - Central Coordinator
The TypeEngine serves as the main coordinator that manages all sub-engines through dependency injection:
Data Flow Architecture
The engine follows a clear data flow pattern that ensures separation of concerns:
ECS Architecture
The Entity Component System is built with three core layers:
Simplified Layer Structure
Complex System-Component Relationships
Design Principles
1. Separation of Concerns
Each sub-engine has a single, well-defined responsibility:
- RenderEngine: Only handles visual rendering
- PhysicsEngine: Only manages physics simulation
- EntityEngine: Only manages entities and components
2. Dependency Injection
All sub-engines receive their dependencies through constructors, enabling:
- Easy testing with mocks
- Flexible configuration
- Clear dependency relationships
3. Event-Driven Communication
Sub-engines communicate through the EventEngine, providing:
- Loose coupling between components
- Extensible communication patterns
- Easy debugging and monitoring
4. Modular Systems
Game logic is implemented through systems that:
- Operate on specific component types
- Have configurable priorities
- Can be enabled/disabled dynamically
Performance Considerations
ECS Optimization
- Component Locality: Components are stored efficiently for cache performance
- System Priorities: Systems execute in optimal order
- Batch Operations: Multiple entities processed together
Rendering Performance
- Sprite Batching: PIXI.js handles sprite batching automatically
- Culling: Off-screen sprites are culled from rendering
- Asset Management: Efficient texture loading and caching
Physics Performance
- Spatial Partitioning: Matter.js uses efficient collision detection
- Sleep States: Inactive bodies are automatically optimized
- Update Scheduling: Physics updates run at optimal frequency
Architecture Benefits
This multi-engine approach provides excellent modularity, testability, and performance while maintaining clear separation of concerns throughout the codebase.
