In our next chapter, we will get into issues such as bullet/bomb/player/enemy collisions. For now, however, we want to make sure that you understand how images work and how to control them. In this chapter, we learned about graphics and visuals, as well as how to display images programmatically, move them around on the screen, and how to do a basic sprite animation. From a programming standpoint, we learned how to create a new object class and the basics of linking them and calling them from other classes. We also learned how to call a specific method from a new class that we created.
In the next chapter, we will learn about NSObjects, basic object, oriented programming, game logic, state machines, creating your enemy class, and more.
