Are there any examples of a project using Flash for UI (store, choosing game, etc.), then switching to Unity webplayer “onGameStart” in the same page? Then back to the Flash UI “onGameComplete”?
I’ve put together an example project which is available on the forums: http://forum.unity3d.com/threads/136242-Flash-Example-Flash-UI-over-Unity-SWF-Content. This has a very basic example of how you can have Flash UI’s over your Unity published swf content.
Please note that rendering Flash content on top of the Unity swf in this way can have a large performance impact.
You can create UI elements in Flash and send messages from them to the Unity published SWF in the same way as done in the Preloader example. I am working on a full UI example which I should be able to upload tomorrow.
