Swift Game Development - Third Edition

Wiring up the sprite onTap events

Your games will often require the ability to run code when the player taps a specific sprite. I like to implement a system that includes all the sprites in your game so that you can add tap events to each sprite without building any additional structure. We have already implemented onTap methods in all of our classes that adopt the GameSprite protocol; we still need to wire up the scene to call these methods when the player taps the sprites.

Note

Before we move on, we need to remove the Core Motion code, since we will not be using it in the finished game. Once you finish exploring the Core Motion example, please remove it from the game by following the previous section's bullet points in reverse.
