If you already know a lot about AS2 and you wish to learn AS3, this video should get you past some of the simple differences.
Note:
Math.round(Math.random()*9)
should have been
Math.floor(Math.random()*10)
There are many, many other differences, such as:
_root. is now MovieClip(root).
attachMovie() is now addChild() and removeMovieClip() is now removeChild()
getBytesLoaded() is now stage.loaderInfo.bytesLoaded - Notice that it's now a property
All events have to be tracked as an event listener (see video)
_rotation is now rotation
But so far I haven't found anything you can do in AS2 that you can't in AS3.
If you need further help, consult either Google, or me ;)
