I need to make it so you can drop an object into a glass
cylinder, however, once it's in the cylinder I don't want the user
to be able to drag it out the sides of the cylinder...
I tried creating an invisible object with which the element
performed a hitTest and if true then stopDrag but the problem with
that is then you could no longer drag it (sorta like it was stuck
to the invisible object)...here's my code...
