Hi everyone, can someone PLEASE show me how to apply the advanced transitions effect (found in this tutorial [http://www.kirupa.com/developer/mx2004/transitions.htm](http://www.kirupa.com/developer/mx2004/transitions.htm) ) to as3 files? i’ve been racking my brains trying to find a way around it since the \_root no longer applies to THE main timeline (only the timeline of the current swf, regardless of how many other swfs its placed into ). i thought i had it fixed when I began using

this.parent.parent.someLoader.load()

but of course it gives me an error because the loader which i am calling upon is not within the swf where i am testing the movie so i get an error of

"cannot access an object with a reference of null… "

please help, i haven’t been able to load external swfs w/ transitions since i began learning as3 4 months ago.
