Chapter 5: System's Behavior Layer

Data is only half the story. In Chapter 5, we transition from static components to the active Behavior Layer of V-Engine. We explore how to implement logic-heavy systems that are decoupled, testable, and optimized for cache-friendly execution. In this video, we cover: • The Role of Systems: How systems iterate over specific component signatures to transform game state. • The BaseSystem Contract: A deep dive into the unified lifecycle—init(), update(dt), and shutdown(). • Singleton Pattern & CRTP: Why core systems use the Singleton template for thread-safe global access. • SystemManager Orchestration: How we enforce deterministic update orders using priority levels (Critical to Lowest). • Inter-System Communication: When to use Direct Reference (tight coupling), the Event System (loose notifications), or the Job System (parallel tasks). • Catch2 Testing: Best practices for validating system behavior and handling edge cases. Technical Highlights: • BaseSystem inheritance and initialization order. • EnTT view iteration for high-speed logic updates. • DOD-friendly patterns like Frame Skipping and Lazy Resource Loading.
