This circular preloader can be used as self loading, which means you just put it on first frame, and your content on second, or you can use it for loading external content(jpg, pngs, swfs… ). For preloading external content all you need is to place this circular preloader somewhere on scene, and define target movieclip by setting one variable in preloader. This Circular Preloader will listen your clip and automatically start preloading when catches some data to being loaded to this clip. It will also auto center self on that clip, so you don’t need to do anything.
