Using the HUD and Renderer classes

Declare an instance of the HUD and Renderer classes as members of the GameEngine class as highlighted in this next code:

class GameEngine extends SurfaceView implements Runnable,
GameStarter {
    private Thread mThread = null;
    private long mFPS;
    private GameState mGameState;
    private SoundEngine mSoundEngine;
    HUD mHUD;
    Renderer mRenderer;

Initialize the instances of the HUD and Renderer classes in the GameEngine constructor as highlighted next:

public GameEngine(Context context, Point size) {
      super(context);
      mGameState = new GameState(this, context);
      mSoundEngine = new SoundEngine(context);
      mHUD = new HUD(size);
      mRenderer = new Renderer(this);
}

Now we can add a call to the draw method of the Renderer class in the run method as highlighted next:

@Override
public void run() {
      while (mGameState.getThreadRunning()) {
          long frameStartTime = System.currentTimeMillis();
   ...
