How do I handle user input in a C++ game?

In C++, handling user input typically involves using libraries like SDL or SFML. You can capture keyboard and mouse events through event polling.

Can you give me an example of handling keyboard input?

Sure! Here's a simple example using SDL:

if (event.type == SDL_KEYDOWN) {
    switch (event.key.keysym.sym) {
        case SDLK_UP:
            // Move player up
            break;
        case SDLK_DOWN:
            // Move player down
            break;
    }
}

What about mouse input?

For mouse input, you can check for mouse button events like this:

if (event.type == SDL_MOUSEBUTTONDOWN) {
    if (event.button.button == SDL_BUTTON_LEFT) {
        // Handle left mouse click
    }
}

Are there any best practices for input handling?

Yes! It's best to separate input handling from game logic, use a state machine for different game states, and ensure input is responsive.
