AS3 - Tweening bitmapData or alternative?

2009-07-09

Hello,

I am working on a kind of pro bono site right now that I could use some advice on.

You can see the site here.

My problem is when you hit the books button and the site scrolls to the right it's a little bit jerky.

I know it is because I am using a bitmapdata fill for the background and bitmap data only like whole pixels. I am using TweenMax.

I tried building a simple tween engine using the Timer making the bitmapdata land on whole pixels but for some reason it is even more jerky.

If anyone could offer suggestions for a good method to make this happen it would be greatly appreciated.

Thanks in advance.

I don't think there is much you can do apart from increasing the frame rate. The image tearing/ripping can't be avoided, Flash's refresh rate isn't synced to the system graphics card so they don't redraw at the same time.

Thanks Nutrox,

It's not to bad, but I was just wondering if there was a trick to smooth it out or even an alternative to using the bitmap fill. I could just use a png, but the books are added dynamically through an xml file so I need the background to be the length of the tweened movie clip no matter how long it is.
