Summary
In this chapter, we've learned how to draw 2D images, move them around and use sprite animation. With this knowledge, we could go a lot further: we could make the enemy move and drop rocks (that fall because they are subject to "gravity" and "explode" on impact). We won't do that in this chapter as it uses the same knowledge as we've gained so far, but it is available in the resources that come with this book. If you want, you can take a look at it.
In the next chapter, we will leave the realm of 2D, and add an extra dimension. Let's start drawing 3D models!
