I am trying to make a simple animation of a rotating ball run as smoothly on a Retina display as it does on the iPad. I have set the acceleratedrendering to true in openStack, and the layerMode of the button is set to dynamic. I even increased the number of png's I am cycling through from 25 to 50. On the Retina simulator, it looks like I am looking at it with double vision. What am I doing wrong?

Hi chelling,
Have you tried with just one image and using "angle"? Check it out in the Dictionary.

That works pretty well for the ball. Thanks Simon! It would still be nice to have a way to do the animation cycling through png files. Not all animations are simple rotations. Do you think that a movie file will have to be used in those situations?

Swapping through image files is processor intensive, not something you want to do on a mobile device.
Here a nice one from Scott Rossi

That's pretty much how I am managing the animation. There are two script local variables, one holds the number of images and the other holds the current image number. So, in the game loop, I am checking to see if the current frame + 1 is > or < the number of images, and then setting the icon of the button accordingly. This is from Game Academy. Do you think if I used less images it would run smoother on the Retina Display? I thought that swapping images was the preferred way to manage animations, so I am pretty surprised to learn that it is actually processor intensive.

Maybe memory intensive is a better description.
Now if you did a lot of work and manipulated points of a graphic object you'd be rocking.

Right - SVG support cant get here soon enough
