Ohhhh .... i was found solution with ActionTween, all is fine with web version, but when i compile on andoid catch this:"Assert failed: target must implement ActionTweenDelegate". I see posts with this problem and promices about fix last 4 years. SAD
By the way, numbers animation really needed in game design... smooth score counter, smooth progress bar, animation change size of panel (scaling will deform all childs).
Yes i can do this with update func, but i see many problems like: setString in every update will dramaticly decrese fps, you cannot use easing easy like with actions and other small bugs and inconveniences.
So, some one have some ideas how to?
