Chapter 7. Implementing Collision Events
So far, we have let the SpriteKit physics simulation detect and handle collisions between game objects. You have seen that Pierre Penguin sends enemies and coins flying off into space when he flies into them. This is because the physics simulation automatically monitors collisions and sets the post-collision trajectory and velocity of each colliding body. In this chapter, we will add our own game logic when two objects come into contact: taking damage from enemies, granting the player invulnerability after touching the star, and tracking points as the player collects coins. The game will become more fun to play as the game mechanics come to life.
