Fortunately, DirectX provides several methods that make this technique viable, and we’ll examine a demonstration of this in the chapter on input techniques. Once the input has been retrieved, it is translated into events that are meaningful in the context of the game. For example, if the joystick button was pressed, the function for starting a missile or a bullet volley would be called. How the input is translated is, of course, dependent on the type of game itself. The result of such user actions will be apparent after the sprite updating segment has been called and the next frame of animation has been drawn to the screen.

If the user wanted to watch a non-interactive animation, she would have watched TV or gone to the movies. Providing a natural means of user interaction is a very important part in the overall design of a game. While a game may be pretty to look at and pleasant to listen to, if it is difficult to use, it won’t be used long. The most appropriate means of user interaction will depend on the type of game. Obviously, flight simulators would best be controlled through a joystick of some sort, while games with lots of moving pieces that can be repositioned freely should probably use the mouse.
