Embedding a unity-generated swf in another one

Hello. I have two silly unity generated swfs and I want one to be loaded and displayed within the other. I’ve tryed:

ActionScript.Import("flash.display.Loader");
ActionScript.Import("com.unity.UnityNative");
ActionScript.Import("flash.net.URLRequest");

ActionScript.Statement("var myLoader : Loader = new Loader;");
ActionScript.Statement("var url : URLRequest = new URLRequest(\"Cena2Loader.swf\");");
ActionScript.Statement("myLoader.load(url);");
ActionScript.Statement("UnityNative.stage.addChild(myLoader);");

But I get the following error:

Fatal Error : RangeError: Error #1506:  
The specified range is invalid.
at com.unity::UnityNative$/NativeExt_PlayerLoop()
at com.unity::UnityContentInternal/playerLoop()
at com.unity::UnityContent/onEnterFrame()
Native_Init called while already initialized

I have also tryed creating a custom preloader swf for the second one, but no success so far. Any ideas?

Loading one Unity SWF and adding it to the stage of another Unity SWF in this way is not supported.

If you wish to load Unity content from external SWFs, you could use asset bundles for this. This would allow you to load scenes/assets etc at runtime. Using asset bundles for Flash export works the same way as other asset bundles, you just need to ensure the target is set to FlashPlayer.

If, on the other hand, you simply want to embed your Unity SWF within a standard SWF, there is an example of how to do this on the forums: http://forum.unity3d.com/threads/145294-Flash-Custom-Splash-Screen-Single-SWF

If neither of those options are viable for your project, please provide more details on the effect you’re trying to achieve and why those projects need to be separate SWFs.

Thanks for the answer. I’m building a unity system flash-targeted composed of independent SWF modules (some are 3rd party). Some of these modules are unity-made, but not all of them.

Therefore, it is necessary to load SWF modules inside my Unity project, unity-made or not.

About the use of AssetBundles, I wonder if I will be able to load content directly from the SWF, something like:

WWW("http://myserver/moduleX.swf").assetBundle.assetX

The second option will not suit me since I’m working with two unity-based SWFs.
