hello…

If you have a group of movie clips stored in an array and the movie cliops are placed on the stage randomly, and use your arrow keys to move a box on top of one of the movie clips - how can you “tell” Flash which movie clip you clicked on?

Right now I’ve got a for loop going which loops through the array that has stored the movie clip instances, presumably the hitTestObject would eventually get a hit…But this doesn’t work, especially inside an event handler where when I press the right arrow on my keyboard.

```auto

if (event.keyCode == Keyboard.RIGHT) {
   box.x += 5;
   for (var i:uint = 0; i <= numberOfClips; i++) {
      if (box.hitTestObject(arrayOfMovieClips*);
         arrayOfMovieClips*.x += 5;
      }
   }
}

```
