It’s time to put your skills to the test and make your own app, starting from a blank canvas. This time your challenge is to make a shooting gallery game using SpriteKit: create three rows on the screen, then have targets slide across from one side to the other. If the user taps a target, make it fade out and award them points.
How you implement this game really depends on what kind of shooting gallery games you’ve played in the past, but here are some suggestions to get you started:
Those are just suggestions – it’s your game, so do what you like!
Tip: I made a SpriteKit shooting gallery game in my book Hacking with macOS – the SpriteKit code for that project is compatible with iOS, but rather than just reading my code you might prefer to just take my assets and use them to build your own project.
As always, please try to code the challenge yourself before reading any of the hints below.
