Learning XNA 3.0

What You Just Did

Stop right here and give yourself a nice, hefty pat on the back. Solid software design is hard to master. Far too many developers dive into code without thinking ahead, and the result is a mass of spaghetti code that quickly becomes unmanageable. Let's review what you've done here:

• You created an inheritance hierarchy for sprites, including a base class handling animation and two derived classes handling user input and automated movement.

• You learned about GameComponents, which can be used to create a modular design of interchangeable components.

• You created a SpriteManager class that handles updating and drawing of sprites as well as checking for collisions.

• You cleaned up the Game1 class to facilitate future development in coming chapters.
