How can I implement AI in a C++ game?

You can implement AI in a C++ game using techniques like finite state machines, behavior trees, or pathfinding algorithms.

What are finite state machines and how do they work?

Finite state machines (FSMs) are models of computation that can be in one of a finite number of states. They transition between states based on inputs, making them useful for controlling game character behaviors.

Can you give me an example of a simple FSM in C++?

Sure! Here's a basic example of an FSM for a game character:

enum State { IDLE, WALKING, RUNNING };

class Character {
    State currentState;
public:
    void update() {
        switch (currentState) {
            case IDLE:
                // Handle idle behavior
                break;
            case WALKING:
                // Handle walking behavior
                break;
            case RUNNING:
                // Handle running behavior
                break;
        }
    }
};

What about pathfinding algorithms?

Pathfinding algorithms, like A*, help characters navigate through a game world by finding the shortest path from point A to point B while avoiding obstacles.
