Roll SpriteKit Node Around Phone Screen Using Core Motion Accelerometer Data

This was a fun little project I made to learn about SpriteKit and Core Motion, and I think it gives a cool visual effect. In this iOS project, we’ll use SpriteKit and Core Motion to create a node that will roll around the phone screen using data from the accelerometer.

Here’s an outline of the article:

First, let’s set up our project. Open Xcode, go to File → New → Project to create a new project. Then select the Game template under the iOS tab. Next, name your product, and make sure to select SpriteKit as the Game Technology.

Since we won’t be needing the default SpriteKitScene files for this project, we can delete the two .sks files that Apple provided us with.

First, let’s remove all the default code that Apple provided us with in GameScene.swift. We will only be using didMove and update method. We should also clear the code in the didMove method.

didMove will be called when your scene is about to be presented by a view. Here, we can create the scene’s contents.The update method tells the app to perform…
