How to create Preloader in AS3

Question

My flash applications is little bit big, so i want to embed a preloader in my application, So can anyone please tell me how to create a preloader in new \'Scene\' and load

Answer 1

[Frame(factoryClass='Preloader')] no longer works in the new ASC 2.0 compiler. Instead, the preloader becomes your document class, and you need to add an Additional Compiler Argument to tell flash to include your main class on the second frame (do not reference it in the preloader):

-frame=NameDoesntMatter,Main

Does ASC 2.0 recognize [Frame] metadata tags (ex: for Preloader factoryClass)?
