Latest Flash Professional has 3 kind of tweens using timeline: Motion Tween, Shape Tween and Classic Tween.
I made classic tweens using flash Tween class or external scripts like Tweener or Tweenlite.
But is it possible to create a “Shape Tween” using just AS3?
If yes, how?
No.
You’re thinking of the kind of ‘morphing’ shapetween that Flash has, right? Those are not available in AS3-code. You could try to workaround that by tweening different parts of a shape by yourself, but it will be a lot more work and I don’t think you’ll ever be able to make it look as nice.
