Having just had a failed attempt at getting a scrolling game working in HTML5, I went to Flash, the gold standard of web games expecting to see an amazing improvement in my simple vertical scrolling game. But alas, I must be doing something dreadfully wrong.
I built the simplest example I could just to see an endless stream of obstacles move top down for the player to avoid, but the scrolling is very choppy. Flash must be better than this so it has to be something fundament I'm doing wrong. I experimented with a variety of FPS (what is recommended?) and adjusting the value of the Y position on each step.
I have attached the project files (except the FLA which is forbidden apparently) for reference as it could be a setting or my approach of using addChild and then adjusting the Y value during the ENTER_FRAME event. Any guidelines that could improve this scrolling would be greatly appreciated.
