Flixel - How to load and play an embedded swf file - actionscript-3

Question

I have been searching the web and all of the codes I have found are to play external swf files that have a timeline. The file that I am trying to load does not have a timeline. I am using the Flixel framework for this project and the file that I want to play is also made in Flixel(don't have the source file just the swf file).
Most of the code I have is from a cutscene template that I found on the Flixel forum. Here is what I have so far:
package
{
import org.flixel.FlxState;
import org.flixel.FlxG;
import flash.display.MovieClip;
import flash.media.SoundMixer;
import flash.events.Event;
public class SponsorsState extends FlxState
{
//Embed the cutscene swf relative to the root of the Flixel project here
[Embed(source='assets/DirtPileLogo.swf', mimeType='application/octet-stream')] private var SwfClass:Class;
//This is the MovieClip container for your cutscene
private var movie:MovieClip;
//This is the length of the cutscene in frames
private var length:Number;
override public function create():void
{
movie = new SwfClass();
//Set your zoom factor of the FlxGame here (default is 2)
var zoomFactor:int = 2;
movie.scaleX = 1.0/zoomFactor;
movie.scaleY = 1.0 / zoomFactor;
//Add the MovieClip container to the FlxState
addChildAt(movie, 0);
//Set the length of the cutscene here (frames)
length = 100;
//Adds a listener to the cutscene to call next() after each frame.
movie.addEventListener(Event.EXIT_FRAME, next);
}
private function next(e:Event):void
{
//After each frame, length decreases by one
length--;
//Length is 0 at the end of the movie
if (length <= 0)
{
//Removes the listener
movie.removeEventListener(Event.EXIT_FRAME, next);
//Stops all overlaying sounds before state switch
SoundMixer.stopAll();
//Enter the next FlxState to switch to
FlxG.state = new PlayState();
}
}
}
}
When I run this I get this error: Type Coercion failed: cannot convert SponsorsState_SwfClass#fb5161 to flash.display.MovieClip., all I want to do is play the swf file for a set frame count then move onto the next state.
Any ideas on how to do this?

Answer 1

Try to replace the following:
[Embed(source='assets/DirtPileLogo.swf', mimeType='application/octet-stream')]
private var SwfClass:Class;
//This is the MovieClip container for your cutscene
private var movie:MovieClip;
into
//Mark your symbol for export and name it => MyExportedSymbol
[Embed(source='assets/DirtPileLogo.swf', symbol = "MyExportedSymbol")]
private var SwfSymbol:Class;
//Make sure that MyExportedSymbol base class is MovieClip
private var movie:MovieClip = new SwfSymbol;
Basically, you mark your symbol for export, give it a name and use that in the embed code. You will embed that symbol only.

Answer 2

You are incorrectly setting a mimeType on your embed. Remove the mimeType and it should work properly. See the docs on embedding assets for more information.

Answer 3

I believe the solution you are looking for is to use the Loader class.
[Embed (source = "assets/DirtPileLogo.swf", mimeType = "application/octet-stream")]
private var content:Class;
private var loader:Loader;
public function Main():void
{
var data:ByteArray = new content();
loader = new Loader();
addChild( loader );
loader.loadBytes( data, new LoaderContext(false, new ApplicationDomain() ) );
// ... add listener to loader if necessary, etc...
}
