A button using co-ordinates?

1

Hi,

I’m stuck:q:

Imagine a menu system where a button is draggable, as you drag it around it doesn’t do anything until it it reaches a specific co-ordinate. Then when it crosses it, it loads an external movie.

O.k

There are rules though, the button needs to be able to have more than one set of co-ordinates, which are not single points but stretch across the movie (horizontal and vertical) , this is so it can load more than one external movie. Its basically a navigation.

here’s a pic to help you to visualise : -

Any ideas on how I can achieve this?
