Hi Vishal,
I apologise ahead if I'm being dense here, but nobody seems to have
mentioned the obvious solution:
Looping through the mcs in your third party flash movie and checking for
hit-test with the mouse position.
var hit_array:Array = [];
for (var i:String in target_mc){
var mc:MovieClip = target_mc[i];
if (!mc instanceof MovieClip){
//not a movie clip - ignore
continue;
}
//Check for hit test
if (target_mc[i].hitTest(_root._xmouse, _root._ymouse, true)
hit_array.push(target_mc);
}
}
At the end of it you have an array of all the movie clips that "scored" a
hit test.
This code is just off the top of my head, an thoroughly untested. Also
Depending on the structure of your flash movie, you will probably want to
delve deeper and test for a hit within each movie clip that you encounter.
It's also not very efficient, especially if you have to do recursion, so I
wouldn't recommend doing it too often. (don't use onMouseMove but rather an
enterFrame event, an interval or some kind of once-off event - depending on
your application).
Alternatively, if you already know which objects should be tested, you can
do this more efficiently by hard-coding them manually into an array and
looping within the array to check for a hit test. Not pretty, but should
work.
And finally, something that occurred to me while writing this post, you
could try temporarily switching off the _visible property of the overlapping
clip just before checking for _droptarget - and then switching it on again.
This might be the least processor-intensive way of doing this.
Cheers,
Karina
