Question

Timeline vector animation in flash for iOS is...

Actually suprising smooth!

I've made about 40 full screen animated vector animations and they all run at my target 15 frames per second (which is fine for cartoons). I have not had to make very many compromises. It works really well.

And it runs great on the iPad 1, my slowest iOS device.

Thanks Adobe!

Hi!

I have a question: what SDK do you use naw and what is did  you find any difference in animation performance between AIR 3.1 and the next SDK?

Thank you in advance

Timeline vector animation works ok in Direct render mode, except perhaps on iPad Retina if the changing area is too large. In my apps that use a lot of vector animations, and Direct render mode, I have iPad 3 disabled in the XML, so it runs at non-Retina sizes. If you tried all unique frame animations in GPU render mode you would run into GPU memory limits.

If your animation is reusing lots of symbols, rather than being all hand drawn unique frames, you can get away with using GPU render mode, and then even get 60 fps.

Sorry to revive this discussion.. but I have a legacy app that uses all classic display list and lots of vector animations, but the frame rate requirement is very low, its all 12 fps fixed.  We ported to iOS and we use CPU mode because back when Air for iOS was very young, we tried GPU mode and it was a complete disaster.. memory leaks and all manner of problems, never mind that classic filters didnt work.

This is before Direct mode even existed. Is direct mode safe(r) to use than GPU mode for "classic" timeline animations?  I ask because now I want to implement a front-end for the applicaiton and I'd love to use Starling/Feathers. But it requires Direct mode.  I played with it a little bit and things seemed to be working but I can't afford to cause instability or memory issues for the sake of performance.

The animations will be part of my app "Phonics and Reading" and the app "Phonics and Reading Lite" (free version). The animations are part of an update I'm working on and I should have it online in a couple weeks. I'll keep ya posted
