Trigonometry for iOS Game Developers – Part 2

Nick Lockwood continues with Part 2 in his series on using trigonometry to build iOS games.

“In this second and final part of the series, you will extend your simple space game by adding missiles, an orbiting asteroid shield and an animated “game over” screen. Along the way, you’ll learn more about the sine and cosine functions, and see some other useful ways to put the power of trig to work in your games.”
