In Flash, a preloader can give a user good information about the progress of a download.
Last week, in Part 1 of this series, I demonstrated how to build a custom AssetLoader class that loaded an image and placed the image on the stage. This week, in this Part 2, I'm going to finish it up by displaying the progress of the image in the form of a progress bar and percentage text. I'll start by setting up the progress bar in Flash. I'll then create a custom class that will scale the bar to the percentage of the image that has been loaded. Lastly I'll update the progress text.
