Coding the Bat input handling
You probably remember we saw the onTouchEvent method in the Sub' Hunter project. It was provided by the Activity class. In this project, however, the input handling is not in the Activity class. If it were, we would need to somehow share values between the PongActivity and PongGame classes and things might get into a bit of a muddle. Fortunately, the onTouchEvent method is also provided by the SurfaceView class, which the PongGame class extends (inherits from).
This time, we will make our code a little bit more advanced to handle left, right, and stop as well as to trigger setting mPaused to false and start the game.
Important note
Even this more advanced touch handling code is still quite primitive compared to a professional game. We will increase the professionalism and effectiveness of our touch handling code in the final two projects. It is then left as an exercise for you to come back and improve the Pong game code.
Add all the code...
