Question

I\'m in the process of making a game (a shmup) and I\'ve started to question the accuracy of the timers in ActionScript. Sure, they\'re accurate enough when you want to tim

Answer 1

BitmapData.scroll and BitmapData.copyPixels are the fastest way to render in flash right now, although on a few systems, using movieclips with gpu acceleration is slightly faster. Each quad is rendered as a separate texture in OpenGL, so its not what you'd expect from an ordinary GPU accelerated application. I know, because I profiled both ways in my game. One thing that you can do to improve response time is to call your game update from the input event handlers. That way, you hear correctly timed sounds even when your game's framerate is lower, and the application will feel more responsive.
