I've seen a few people asking how you can create a UI/HUD in Flash and have that appear on top of your Unity published SWF content. Here is a basic example which was based upon the existing Flash Preloader example. The basic preloader screen, button, text fields etc seen in the demo were created in Flash and published to a swc. I've then used the same sendMessage functionality from the preloader demo to show you how the HUD/UI can communicate with your Unity SWF content. The contents of the zip file are in three folders: AS3-UI - The AS3 source and SWCs required to build the UnityContentHost.swf file found in the BuiltExample folder. This swf contains the preloader and ui. I've included the fla (CS6) for reference purposes. BuiltExample - The full demo. Open the FlashUIExample.html file in your browser to run the demo. UnityContent - The Unity project used to generate UnityContent.swf in the BuiltExample folder. This should hopefully give you a good starting point for how you could build UIs in Flash. Please note that whilst it is possible to show Flash content over your Unity built SWFs, this method of creating your UIs potentially comes with a large performance impact. As mentioned before, the Flash export is still being developed so this example is subject to change at a later date. Enjoy!
