How do you create these \"loading, please wait\" splash screens with a loading bar and percentage for your swf? Does as3 have some built-in methods or should it be designe
There's a few different ways to do this.
Either you can have a two step process - create a swf file that simply loads in the main file, reporting progress (by listening to the progress-event on the loader) and then adding the loaded swf as a child.
Or, you can place all your content on frame 2, and stay on frame 1, checking the root.loaderInfo.bytesLoaded compared to root.loaderInfo.totalBytes values, reporting the percentage and then moving on to frame 2 when done.
Personally, I think method 1 is better, since you don't need to sully yourself with frames.
There is also a third way which uses some weird meta-data tags to simulate the second way, but without frames. It's a bit messy, but should be googleable.
