Adding Particle Effects to Your Game with Emitter NodesIn the previous chapter, you refactored the orb node’s layout and saw how you could use . to move an . back and forth across the scene while making that same node rotate forever. At the end of the chapter, you looked at how you can add colorizing effects to an . using a colorize action.

Hit Testing and Collision DetectionSo far in the game you have not moved the hero, and now you need to get him up on his feet and moving around. You are going to keep this simple and use a one-finger touch to move forward and two fingers to move back. To move left and right, you will use the accelerometer.

Using Sprite Kit with a Scene Kit SceneIn the previous chapters, you worked within the Scene Kit paradigm; however, Apple has created a way for you to add a 2D scene to overlay on your 3D scenes. In this chapter, you will add a 2D scene that will be used for your timer so it can track how long it will take you and your friends to find and capture the enemy.
