Spellcasting

Recognizing design patterns in game-engine code

This is an easy C++ question that tests whether you can identify a classic Gang of Four design pattern by reading production-like code. It's the kind of conceptual check Microsoft and other large game studios use to ensure engineers understand fundamental architectural patterns, not just syntax.

The question asks you to recognise which pattern governs a spellcasting system where actions can be queued and executed in sequence under certain constraints. Success depends on understanding how common patterns solve the problem of decoupling command issuance from execution, and how they enable undo, replay, or queueing of operations.

• Encapsulating requests as objects
• Decoupling invoker from receiver
• Queuing and sequencing actions
• Macro command composition
