Author Topic: Mixing opengl && sf::sprite (Read 1870 times)

Hi. I'm wondering if someone can make a tut for using opengl along with sf::sprites. I want to draw opengl polygons in top of sprite backgrounds. Is that even possible?

Thank you.

There's an example in the SFML SDK that does exactly what you want.

:oops: Oops... I'm sorry about that good Sir.
I got the thing to work, but now I have a new issue: my fps drops from 60~, to 15~ by just calling PreserveOpenGLStates(true). Even if I don't draw any polygons!!! Is that normal? I think I will just stick with 2d for now.

Thank you.

In Debug or Release mode?
