How can I implement finite state machines in C++ for game AI?

To implement finite state machines (FSM) in C++, you can start by defining states and transitions. Each state can be a class or struct, and you can use a switch-case or a map to handle transitions.

Can you give me an example of a simple FSM for a game character?

Sure! You can create a CharacterState class with states like Idle, Walking, and Attacking. Each state would have methods like Enter(), Update(), and Exit() to manage behavior.

How do I handle transitions between these states?

You can use a method in your CharacterState class to check conditions for transitions. For example, if the character is walking and the attack button is pressed, you can transition to the Attacking state.

What are some common pitfalls when designing FSMs?

Common pitfalls include overly complex state machines, not handling transitions properly, and failing to account for all possible states. Keeping it simple and well-organized is key.
