Hello,
I have an existing Flex application with MX/Spark components. But now I'd like to add a Starling component for a text animation. I can't seem to find an example which combines Starling into a "traditional" flex application. Can this be done and do you know of any examples of this?
Thanks a lot,
Frank
Hi Frank,
it seems not a good idea but it works.
Some days ago I have done a little test creating a Flex mobile project mixing Spark components with Starling stuff.
I have used Starling to create a fullscreen touchable background that in a AS3 project works at 40fps on Ipad1 (60fps on IPad3).
So I have put a Spark List ABOVE it, although people says that you should avoid it.
In fact, it seems that display list components above stage3d decrease performance on mobile device.
Anyway, when I scroll the Spark List I have about 25fps (as always, Flex componenents were never so fast). When I scroll the starling background I always get 40 fps.
So it seems to work fine.
To use Starling in Flex 4.6 you have only to set backgroundAlpha=0 in your Views.
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
backgroundAlpha="0"
backgroundAlpha="0" did the trick 
so my code was fine already, only forgot this one.
purpose of my test is to integrate a smooth scrolling text within a flex application. Because this application is sometimes processing incoming data, my scroller now blocks from time to time. That's why I want to move this into a starling component. The test can now continue.......
Thanks a lot fabiobiondi!
I'm happy you solved it
Anyway Josh is developing some cool Starling components (foxHole) but I notify him just few hours ago some performance issues on the LIST component.

If you'll read the post, you'll see I'm trying to develop my own components and I also have some performance issue developing a List with Textfield items.
On Ipad3 everything works very well. I have created a new video right now.

But on IPad1 the LIST and the Video player (that use native display list) works bad (below 15/20 fps)
If you find a good way to create a smooth list with textfield item please let'me know : )

On the topic of mixing flex components and Stage3D there is also this cookbook article that may have some interesting code samples depending upon the type of app you are building:

I'm also attempting to do this. Seemingly, the above link has expired.
I have a game written in mxml and as3. The HUD and menus are MXML components. I'd like to keep them that way to save time on implementation; and would like to use Starling for the animations and scene transitions in the game.
Is there a way to establish communication between spark-or-MXML components and starling?
For instance,
1.) on applicationComplete of an AIR WindowedApplication:
_starling = new Starling(Game, stage);
_starling.start();
2.) inside the Game class, dispatch an event and have it handled in the WindowedApplication.
3.) in the WindowedApplication, have a reference to functions inside the Game() class.
For some reason, I can't get this to work. Is there ever an instance of Game()? If not, is there a work-around to achieve the same results?
