Smooth text scrolling?

[benkyoto]

Is there any way to make a long text scroll smoothly using AS? I tried using a dynamic text field, but that only seems to work with integer line increments so the movement feels jumpy.
Thanks in advance for your time/help.

Nope, this was not exactly what I was looking for. This uses a sprite and a mask to do the scrolling, not the text field iteslf, so you could do the same thing in the authoring environment by tweening text with a mask applied to it.
The problem with this is that as text advances, the animation becomes jumpy, making it quite unreadable (perhaps the cpu overhead of calculating every frame of the *very large* masked object).
The kind of text I'm talking about here is LONG. Like 20+ screen heights. And I would like it to move automatically; think movie end credits.
Any other ideas?
