Beginning iOS 5 Games Development: Using the iOS 5 SDK for iPad, iPhone, and iPod Touch

Summary

In this chapter we looked at a technique to create actors in our game that are drawn programmatically. We created a new class call VectorRepresentation to handle the details of create a UIView for our code to draw on. We used these new vector-based actors to create a health bar and a simple bullet. The chapter continued by showing two simple examples of creating particle systems. The first example reused the art for the asteroids to create a sense of debris when we exploded the asteroids. The second example used vector-based particles to create acomets with glowing tails. The actors created in this and the previous chapter will be used to create a complete game in Chapter 10.
