Rotating and shooting toward the player
In the final AI system, the robot turns and fires bullets toward the player if the player is within range.
Bind the Nk^kp[Odkkp class to the Nk^kp oui^kh to see this work. The robot fires bullets in one-second
intervals. Figure 10-20 illustrates what you will see when you test the project.

You'll be happy to know that you already know 90% of the code in this class. In fact, everything from
how the object rotates to the method that fires bullets is virtually identical to the code in the Lh]uan
class. The only really new thing is the introduction of AS3.0's built-in Peian class, which is used to time
the firing of the bullets. You'll look at how the Peian class works in detail ahead.
