Okay, so I have an FLA with a series of embedded movieclips:
garden > tree > branch > twig > flower.
I want a static function -- in an as 2.0 class -- that, when given
flower, returns tree. In other words, you can give in an embedded
movieclip and it finds that clips ALMOST outermost parent.
Here's my class & function:
class com.research.StaticRecurse
{
public static function
getOuterMostParent(mc:MovieClip,mcRoot:MovieClip):MovieClip
{
if (mc._parent._name == "garden")
{
trace("inside getOuterMostParent: " + mc);
return mc;
}
else
{
getOuterMostParent(mc._parent);
}
}
}
and inside the fla, I use the following code:
import com.research.StaticRecurse;
var innerMostChild:MovieClip = garden.tree.branch.twig.flower;
var mc:MovieClip = StaticRecurse.getOuterMostParent(innerMostChild);
trace("outside getOutMostParent: " + mc);
the trace is as follows:
inside getOuterMostParent: _level0.garden.tree
outside getOutMostParent: undefined
As you can see, the first trace -- which works beautifully -- occurs
RIGHT BEFORE the return statement. But the value that's actually
returned is undefined. I've never encountered anything like this
before. To me, it seems as if I'm doing this:
function x():Number
{
var n:Number = 1000;
trace(n); //1000
return n;
}
trace(x()); //undefined
... which would be insane. I'm guessing it's a scoping issue that has
to do with recursion and the fact that this is a static function
(which it kind of has to be). Why is this happening? Is there a
workaround? Thanks!
