Reusing the Pong engine

Feel free to copy and paste all the code in this section. It is nearly identical to the structure of the Pong game. What will vary is the other classes we will create (Bullet and Bob) as well as the way that we handle player input, timing, updating, and drawing within the BulletHellGame class.

As you proceed with this section, glance over the code to notice subtle but important differences, which I will also point out to you as we proceed.

Edit the BulletHellActivity class to look like this next code:

import android.app.Activity;
import android.view.Window;

// the same as the Pong project
public class BulletHellActivity extends Activity {
// An instance of the main class of this project
     private BulletHellGame mBHGame;
@Override
protected void onCreate(Bundle savedInstanceState...
