FadeIn
« on: July 05, 2013, 09:26:55 pm »
Hi!
I'm asking for a fadeIn and for a fadeOut effect, of course how I could do that.
The problem is, that my background isn't regular and in some cases it is regular, but the alpha value is <255 so that a simple sprite wouldn't work.
It wouldn't be soooo hard*, if I wouldn't want to make it like this. A smooth fading from left->right and vice versa.

*I would code a class which inherits from sf::xyz and which would give me access to the letters, if possible. It was just an idea, I didn't checked if it would work or not.

Please give me suggestions!  :-\
Thanks! :)

This is not directly possible with SFML. A few ideas off the top of my head would be to implement your own sf::Text and draw each letter with a different alpha. Another option would be something similar to render masking as described in this thread.
