How can finite state machines be used in C++ game AI?

Finite state machines (FSMs) are a powerful way to manage game AI behavior. They allow you to define states and transitions, making it easier to control character actions based on game events.

Can you give me an example of a finite state machine in a game?

Sure! For instance, in a simple enemy AI, you might have states like 'Patrol', 'Chase', and 'Attack'. The enemy starts in 'Patrol', switches to 'Chase' when it sees the player, and then to 'Attack' when in range.

What are the benefits of using FSMs over other AI techniques?

FSMs provide clear structure and are easy to debug. They also simplify the implementation of complex behaviors by breaking them down into manageable states.

Are there any limitations to using finite state machines?

Yes, FSMs can become complex and hard to manage if there are too many states or transitions. They may also struggle with behaviors that require more fluidity or adaptability.
