If you mean a frame in a layer in Flash IDE, the one with white circle, the answer is
you can't. Layers in AS3 are not saved. They are merely converted to depth order.What you can find out is if
this particular frame doesn't contain any children(when all layers are combined) as it was already mentioned usingnumChildrenproperty. If you have any shapes, bitmaps or movieclips on stage they all will be listed as children.But you also might have something drawn in your sprite’s
graphicsobject which makes it non-empty in some way. If you want to check that you have to draw it in aBitmapDataand examine its content.
