Shane's origional Post (October, 2012):

I started looking at Starling 2 days ago, and quickly realized a great truth that I'm sure you are all very familiar with: Starling MovieClip != Flash MovieClip.

Obviously, we still want to be able to create content and animations with Flash, so the typical solution is to walk through each frame of a Flash MovieClip and create a texture from it. With large and/or long animations this is a terrible waste of GPU memory. And you've lost all the display list hierarchy (if that was important to you).

So I wrote some code that attempts to really convert a Flash MovieClip to a Starling IAnimatable Sprite. It's many AS files worth of code, so I won't paste it here... but here's the basic psuedocode:

Walk through the Flash MovieClip display list: For each child If it's a container Create a Starling Sprite (IAnimatable if more than 1 frame) Start over, using the new Sprite (recursive) Else Create a Starling Texture from it. (uses CRCs to avoid dups) The code can be found here: http://DigitalLoom.org/CodeWeaver/FlashMovieClipConverter-1.4.zip Version 1.4 - Added command-line AIR app to pre-convert the Flash MovieClip. version 1.3 - Performance enhancements, and added clone() function. version 1.2 - Added typical MovieClip controls (gotoAndStop, etc.) version 1.1 - Added Texture Atlasing

Usage - Run-time conversion:

var animSprite:ConvertedMovieClip = FlashMovieClipConverter.convert( flashMC ); Starling.juggler.add( animSprite ); Usage - Pre-conversion via command-line AIR app

StarlingConverter [-noSortBitmaps] MyMovieClip.swf var clipData:XML = // Load MyMovieClip-clipData.xml var atlasBitmaps:Vector. = // Load MyMovieClip-atlas1.png (and atlas2, atlas3, etc.) var animSprite:ConvertedMovieClip = FlashMovieClipImporter.importFromXML( clipData, atlasBitmaps ); Starling.juggler.add( animSprite ); The code is quite limited... it only handles animation of position, rotation, scale, and alpha. But that's 90% of what I usually animate anyway. It was intended to convert Flash MovieClips loaded from SWF files without any AS linkage (as required by iOS), so I can't guarantee it'll work in other situations. Furthermore, I can't spend time supporting it... so if you improve it, just post it back to this thread.

Forgive me if someone else has already created something like this. The only thing I was able to find was emibap's Dynamic Texture Atlas Generator, which didn't appear to do what I wanted.

Usage

Flash Movie Clip Converter - Converts a Flash MovieClip to a Starling IAnimatable Sprite.

This code can be used in one of two ways:

1. Convert an in-memory Flash MovieClip object to a ConvertedMovieClip object:

var animSprite:ConvertedMovieClip = FlashMovieClipConverter.convert( flashMC ); Starling.juggler.add( animSprite );

2. Export the MovieClip information, then import this data at runtime.

a) Install 'StarlingConverter.air' by double-clicking it. (Windows or Mac) b) Open up a command prompt ('terminal' on Mac), and navigate to where your .swf file is located. c) Run '/path/to/installed/StarlingConverter MyMovie.swf'. Output files will be placed in the current working directory. (There is no console output) d) Optional: Multiple .swf files can be specified on the single invocation. Use the '-noSortBitmaps' to skip presorting the bitmaps before they are placed in the atlas image. e) Import with the following as3 pseudo-code:

var clipData:XML = // Load MyMovie-clipData.xml var atlasBitmaps:Vector. = // Load MyMovie-atlas1.png (and atlas2, atlas3, etc.) var animSprite:ConvertedMovieClip = FlashMovieClipImporter.importFromXML( clipData, atlasBitmaps ); Starling.juggler.add( animSprite );
