Communication Patterns and Decoupling Questions

Evaluate knowledge of architectural and code patterns used to decouple game systems and maintain extensibility as complexity grows. Topics include event driven design, observer and publish subscribe patterns, message buses and command queues, dependency inversion, service locators, data flow and lifecycle of events, ordering and reliability concerns, memory and performance trade offs of messaging, testing and debugging strategies, and how these patterns impact extensibility and maintainability in single player and networked contexts.
