If you bought the iPhone Game Development course already, your download link from last week should still be active and have the updated link. Also I’ll upload part 2 of session 3 tonight and email everyone a brand new download link again.
Last night’s update teaches using the accelerometer in the iPhone to make a virtual table to roll a ball on. So if you tilt the phone, a ball will roll until it collides with the edge of the plane. Relatively easy, and darn cool to play with when the app is on your phone.
