I think he is referring to the following class from another thread. One
problem pertaining to your issue is that it doesn't take into consideration
depth. It is still more process intensive then just firing a callback on
rollOver but could be useful for you and give you some ideas:
class com.domain.RollWhileWithin extends MovieClip {
public var rolled:Boolean;
function RollWhileWithin ()
{
rolled = false;
}
public function doRollOver():Void
{
if (!rolled) {
rolled = true;
gotoAndStop("over");
}
}
public function doRollOut():Void
{
if (rolled) {
rolled = false;
gotoAndStop("up");
}
}
}
One level above it, you can manage as many clips as there are.
var checkMouseInterval:Number;
clearInterval(checkMouseInterval);
checkMouseInterval = setInterval(this, "checkMouse", 100); private function
checkMouse():Void {
var i:Number = 5;
while (i--) {
var clip:MovieClip = this["MC_RollClip" + i];
if (_xmouse > clip._x && _xmouse < clip._x + clip._width &&
_ymouse > clip._y && _ymouse < clip._y + clip._height) {
clip.doRollOver();
} else {
clip.doRollOut();
}
}
}

Subject: Re: [Flashcoders] determining which object is displayed at
agivenpoint
Ok. This is what I was missing. Thanks to Karina and Erik for
pointing out that you need to compare the entire parent chain of two
objects to figure out which one is being rendered above the other.
The only thing to add is that in addition to checking depths, the
_visible property needs to be checked for the parent chain for each
object (so if _visible is false anywhere in the parent chain, I
consider that object to be invisible). This works in all cases except
for some TextFields, where the bounding box of the textfield object is
bigger than the area actually occupied by the text. This can be
solved with a custom hitTest() implementation that uses
Textfield.textWidth and .textHeight to get the bounding box of the
displayed text. An interesting corollary is that this method would be
a way to implement onRollOver for TextFields (if that ever proves
useful to anyone).
Steven, I'm not familiar with the class you're referring to. Could
you send the link to it? I'm always looking to improve the simplicity
and efficiency of my code...
