Responding to rollovers with Lingo

You often want some action to occur when the user rolls the mouse pointer over a sprite or
a particular place on the Stage. You can use Lingo to specify how the movie responds to
such rollovers.
Director provides several event handlers that run when the pointer rolls over a sprite. Messages for
each of these events are sent to the sprite script, the script of the cast member, the frame script,
and then the movie script. See individual event handlers and functions in the Lingo Dictionary.
