Preload random items

Hello everyone,

I am making this game, and I am missing something that I cannot figure out. I want to make a preloader that loads random items from different urls, like:

url.com/1.swf
url.com/2.swf
url.com/3.swf

And after it loads it shows up in an empty movieclip. But even tough i have the right idea, i cannot figure out how to script this…:frowning:

Thanks in advance,
Nico
