I am creating an autoscrolling platformer as a fun little project similar to 'Jetpack Joyride' whereby all you really control is the characters up and down movement. Also similar to the various dropdown and helicopter games.
The thing i am curious about is if anyone can advise how you make is so that the scrolling backgrounds are randomily chosen from the available backgrounds. I.e. I would create 10 differwent backgrounds, one would scroll along as you play when it ends a different background would randomily appear and so on.
