BlitMask scroll problem - animation looks jerky

[Chrysto]

Hi;

 

I'm building an infinite image scroller and I'm using BlitMask to scroll the images. On the start the animation is smooth, but after 2-3 cycles of the slider the animation starts to tween jerky. I test it on both mac/pc and this problem seems to occure. Here is some demo http://burnandbass.com/basstaslider/ . For blitting I used this settings:

 

var imagemask:BlitMask = new BlitMask(tempBitmap,tempBitmap.x,tempBitmap.y,tempBitmap.width,_height,false,true,0x000000,true);

 

And then tween the tempBitmap's y property with the default easing ( no easing passed ). On the beginning it is smooth, but after 1 or 2 cycles it start's to be not so smooth. Some ideas?

Hi Bassta,

 

 

The code you provided doesn't shine much light on what could be wrong. for me the demo was very unresponsive and jerky.

I'm kind of surprised as it doesn't look like anything that crazy is happening.

Can you provide more code or upload your source files?

i received your files. I have to say I think my browser was overloaded earlier of something as viewing the example from another computer looked a million times better.

 

haven't looked at the files yet.
