在天地会论坛里无意中看到,搜集来,呵呵.

在MENU里面有三个MENU。分别为
menu_mc,menu1_mc,menu2_mc.

menu.menu1_mc.y=0;
menu.menu2_mc.y=0;
menu.addEventListener(MouseEvent.MOUSE_OVER,myMouseOver);
menu.addEventListener(MouseEvent.ROLL_OUT,myRollOut);
function myMouseOver(e:MouseEvent):void
{
menu.menu1_mc.y=33;
menu.menu2_mc.y=66;
}
function myRollOut(e:MouseEvent):void
{
menu.menu1_mc.y=0;
menu.menu2_mc.y=0;
}
