I was wondering if anyone could explain to me what the actionscript would be if i wanted to duplicate movieClips randomly from the edge of the flash? And how i would make the hit tests for them.

Looking at the tutorial  
[http://www.kirupa.com/developer/actionscript/duplicatemovie\_mx2004.htm](http://www.kirupa.com/developer/actionscript/duplicatemovie_mx2004.htm)  
I don’t get what  
for (i=0; i\<100; i++) {  
means

and what the  
\_alpha  
is in  
{\_x:Math.random()\*300, \_y:Math.random()\*200, \_alpha:Math.random()\*50}

and does it automatically play the movieClip that you duplicated?
