I almost just gave the pdf for chapter 3 (sample chapter in webpage for book); but, the Drill and practice section is not included. Calling class methods/if-statements Ex. 3.31: In your stickman scenario, make the stickman move to the right, so that when you run your scenario, he walks over to the right side of the screen. Ex. 3.32: Using an if-statement and the microphone input method you found above (Ex. 3.26 given below), make the stickman move right only when you make some noise. Experiment with different values for the noise level. This will depend on your microphone and your environment. A good starting point is to make him move when the microphone level is greater than 3. Test. Ex. 3.33: Make the stickman move left when you make some noise, but move continuously right if there is no noise. Test. Try to keep him near the center of the screen by shouting. Defining methods Ex. 3.34: Move the code that moves left when you make noise into its own method. Call this method moveLeftIfNoise. Test. Make sure it works as before. Ex. 3.35: Add another method to your class called gameOver. This method should be called if the stickman reaches the edge of the screen. When called, the method plays a game-over sound and stops the scenario.

This is what it says: Bouncing ball practice Ex. 4.35: Create a new scenario. In it, create a World and an Actor class called Ball. (Give it a ball-like image.) Program the ball so that it moves at constant speed and bounces off the edges of the world.
