how to scroll automatically bit by bit

I made a scroll box and put lots of text block.
I want to scroll automatically bit by bit at runtime.
plz help me how to do this

What does it mean to scroll bit-by-bit; how much is a bit- you want a smooth scroll or skip to the next element, or by x pixels, or by x elements? With certain speed or curve based? Is it a dynamic or set amount of text boxes, are some of them off-screen? What is it for - rolling credits screen?

You’re not being descriptive enough to get a solid answer.

Hi, so not sure if I understand it right but it sounds like an auto-scrolling check the image and let me know if that is what you tried to do.
Otherwise you could use scroll into view.
