Title: How do I layer a sprite onto a bg?
Post by: pabloist on September 15, 2010, 06:49:20 am

I have a colored bg that I'm trying to place a sprite on top of; but the sprite I'm trying to put on top has whitespace. Is there a way for me to get rid of it? I tried using Sprite.SetBlendMode(sf::Blend::Mode::Multiply) but that causes the rest of the character to change color along with the bg.

If there's no code solution, is there a way for me to just get rid of the surrounding whitespace?

(sorry if any of this seems stupid, I'm playing around with the tutorial stuff right now. I also only have MS Paint :P)

I think the function you need is:

Code: [Select]

void sf::Image::CreateMaskFromColor(Color ColorKey, Uint8 Alpha = 0)

Performance wise, how does this compare with using transparent pngs?

I recommend to use sf::Clock to test it for yourself
