Traducido a AS3 tal cual, sería:
Código actionscript:
Ver originalHomePage_mc.addEventListener(MouseEvent.CLICK, ir_url);
HomePage_mc.addEventListener(MouseEvent.ROLL_OVER, m_over);
HomePage_mc.addEventListener(MouseEvent.ROLL_OUT, m_out);
HomePage_mc.addEventListener(Event.ENTER_FRAME, mov);
var over:Boolean;
function ir_url (event:MouseEvent){
navigateToURL(new URLRequest("http://www.home.html"));
}
function m_over(event:MouseEvent){over=true;}
function m_out(event:MouseEvent){over=false;}
function mov(event:Event){
if(over){HomePage_mc.nextFrame();}
else {HomePage_mc.prevFrame();}
}
Ésto lo pones en un frame en el que se encuentre el movieclip HomePage_mc (puedes crear una capa llamada actions)
Espero que te sirva, Salu2
