[Flashcoders] scoping issue (?) with static, recursive function

2007-04-24 Thread me myself 

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!

You need a 'return' before the recursive call:


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
  {
  // Add a return here:
  return getOuterMostParent(mc._parent);
  }
  }
}
