text scroller

"variable.scroll" and "variable.maxscroll" are the extension commands for text fields in Flash. ".scroll" is the line number of the top line in your text field and ".maxscroll" is the maximum line of your text field. An example use of the code would be in a situation where you have two buttons (ScrollUp and ScrollDown), you have a text field (text). To get the text to scroll up and down while the user presses and holds down, create a 3 frame MC for each (scrolling up and scrolling down). In the first frame put a Stop command. In frame 2, place the following:

ScrollUpMC (frame 2):
Set Variable: "textScroll" = /:text.scroll
If (textScroll > 1)
Set Variable: "/:text.scroll" = textScroll - 1
End If

ScrollDownMC:
Set Variable: "textScroll" = /:text.scroll
If (textScroll < /:text.maxscroll)
Set Variable: "/:text.scroll" = textScroll + 1
End If

On the Buttons, place the following code:

Scroll Up Button:
On (Press)
Begin Tell Target ("/scrollUpMC")
Go to and Play (2)
End Tell Target
End On
On (Release)
Begin Tell Target ("/scrollUpMC")
Go to and Stop (1)
End Tell Target
End On

Scroll Down Button:
On (Press)
Begin Tell Target ("scrollDownMC")
Go to and Play (2)
End Tell Target
End On
On (Release)
Begin Tell Target ("/scrollDownMC")
Go to and Stop (1)
End Tell Target
End On

I can't remember where I first saw this code presented. If I can find the reference, I will repost the credit. It may have been on Flashzone a few years back. If someone recognizes, please chime in.
