[flexcoders] Why is my preloader slow and jumpy?
So I'm trying to do a simple preloader for my application. I'm going the implements IPreloaderDisplay route. I have an intro animation for my preloader (it simply tweens onto the stage usinging TweenLite). After the intro animation completes, the progress bar does it's job and then shows the app. The problem I run into is when the intro animation is playing it is real jumpy. Sometimes all I end up seeing is two key frames of the animation. It is supposed to play for 1 sec. Here is my base preloader class: http://pastie.org/453038 And here is the main preloader class that handles the animation and such: http://pastie.org/453041 I'm assuming that the memory Flash/Flex is using is bogging down the machine, so the tween does not render smoothly. Is there a way to delay the start of the rest of the application loading until the intro animation has finished? Best, Adam Duro
