That's it! We just made a game in 20 minutes or so, which shows you just how fast SpriteKit is. I even showed you how per-pixel collision detection works (it's so easy!), how to advance particle systems so they start life with some history behind them, how to run code repeatedly using
Timer, and how to adjust linear and angular damping so that objects don't slow down over time.
Anyone can sit through a tutorial, but it takes actual work to remember what was taught. It’s my job to make sure you take as much from these tutorials as possible, so I’ve prepared a short review to help you check your learning.
One of the best ways to learn is to write your own code as often as possible, so here are three ways you should try your new knowledge to make sure you fully understand what’s going on:
touchesEnded()to make it work.
gameTimerbefore giving it a new value, otherwise you end up with multiple timers.
