I've been wondering the same thing. I have a "shop" in my game and it'd be great to have a scrolling window instead of multiple screens.

I think you want this:
you'll only need to use the y or x, which ever way you are making the text scroll.

I decided to try to make scrolling text and was successful: http://dl.dropbox.com/u/19602014/ScrollingTextv0.2.zip. I haven't commented it and it is based on quite a bit of trial and error where the math is concerned, but maybe you can find something useful from it.

Hi All,

Found this post, and it helps me a lot with my vertical (Y only) scrolling text.

However, I want it to stop being able to be scrolled when it reaches certain areas (i.e. the end)...how do I set limits to do this?

Thanks again,

I'm not entirely sure how to do that. I wasn't happy with the way it continues to scroll at the top and bottom edges, but I didn't work out a solution. I may think something up but in the meantime, anyone else (@MotherHoose) have a good idea?

I played around with self.position.y on the text actor but if I use a condition for the top edge (e.g. y=34), I can either not ever scroll or I can always scroll.

@robert.mccarthy: Okay, I solved the problem. Just needed to add a rule to the text actor that says if self.Position.Y<34 then change attribute self.Position.Y to 34; and a rule that says if self.Position.Y>440 then change attribute self.Position.Y to 440.

Here's the new version: http://dl.dropbox.com/u/19602014/Scrollingtextv0.3.zip
