I've created a game with Flex, and now I'm trying to integrate MochiAds with it. They give you a preloader to use, but most of their documentation is actionscript-centric and oriented toward Flash developers and the Flash IDE.
I tried using the preloader attribute of the mx:Application tag, but they told me that the 'main class' of the application has to be a dynamic class, which they said is impossible with MXML. Any idea how to do this? Seems like most of the Flex docs assume you're starting with an mx:Application tag as your entry point. I've asked on their developer forums as well but haven't gotten many details. Thanks
