Create the text shown in the example. Make a button (see our tutorial on Building Buttons) and add the following action to it:
On (Release)
Begin Tell Target ("/blink")
Go to and Play (1)
End Tell Target
End On
Now draw the small picture
that you will use as your blinker. (I used a crescent moon/circle picture
for this purpose). Lastly, enter a stop action in the first frame of the actions
layer.
