Title: Improving the scrolling text
Post by: PotcFdk on April 09, 2012, 08:13:10 pm

Hey.
I made a fairly simple Text Scroller in SFML2 and I think it doesn't quite cut it.
Currently, it just scrolls horizontally... How could I improve it?
I thought about some kind of "bouncing" while moving horizontally
or something like moving each character individually...
What would be the best approach?

Thanks in advance.

I think we had enough textscrollers back in the days, I don't know if many would appreciate those eye cancer texts. ::)
But if you want to get one anyway, I don't think SFML's sf::Text etc. is the best way, since you'd have to be able to deform the characters. Maybe a shader could help there but I've no experience in that direction.
If you just want a bouncing text without deformation you could move each character on its own.

Thank you for replying, eXpl0it3r.
Moving each letter individually shouldn't be that hard.
How about deformation? Vertex Shader? Are there tutorials?

I made a class called SpriteText which is similar. Each character is an individual sprite, taking its texture subrect from a sprite sheet containing all the characters.

Applying different transformations across each character sprite can yield some interesting results.

You could probably acheive the same using sf::Text, but I went with sprites because I'm more familiar with them.
