Flash 101 (part 5): Spiralling Out Of Control - Dynamic Buttons (
Page 4 of 7 )
By allowing authors to
separate animation sequences into separate movie clip symbols, Flash makes it
possible to add animation and interactivity to buttons as well.
In your
existing Flash movie, create a new button symbol named "spiral-button", and
insert an instance of the static graphic symbol "spiral-image" for the Up state
(in symbol-editing mode). Next, insert instances of the rotating movie clip
symbol "spiral-movie" for the Over and Down states. Finally, for the Hit state,
draw a filled box which encloses the entire spiral - this identifies the active
area of the button.
Now, each time the
button symbol receives a "hover" or "click" event, it will automatically
activate and play the movie clip.
Go back to the Stage, and insert an
instance of your new button symbol "spiral-button". Use Control -> Test Movie
to view the movie clip - you'll see something like this:
