So far, we have completed the first half of our game in the previous chapter. We started by developing the initial structure for the project by introducing the game objects to the screen. Currently, the paddle and ball movement is inactive, but everything displayed in the simulator is scaled according to the original game design. The last phase of completing this tutorial is to add in all the actions that will occur in the game, including object movement and updating the score.
In this chapter, we will cover the following topics:
Moving the paddle using touch events and accelerometer
Collision detection between all game objects in the scene
Removing objects upon collision detection
Ball movement within the screen boundaries
Calculating the score
Win and lose conditions
Home stretch! We can do it!
