In this chapter, we focused our efforts on incorporating playability in the game that we initialized in Chapter 1, The First Step toward SpriteKit.
We explored the different ways through which we can handle touch interaction, and we used them to detect where the user touched the screen and deploy it on the movements of the main character.
In order to make the rabbit move, we had a look at the methods provided by the SKAction
class in order to create and manage actions. Thanks to these utilities, we managed the rabbit's lateral movement and the looped movement of the wall and doors. In this way, we created a group of objects that the user will need to avoid.
Next, we added one of the bases of all games, namely collision detection. As the rabbit will need to avoid the wrong doors, we had to find a way to check whether a collision took place. So, we saw how to detect whether a collision happened and how to handle it in order to convert it into a success or failure.
We used this collision...
