Title: sf::RenderWindow::OptimizeForNonOpenGL(true) not in SVN?
Post by: aisman on April 22, 2008, 07:43:34 pm

Use the SFML SVN with VC2008.

Get compiler error:
'OptimizeForNonOpenGL' : is not a member of 'sf::RenderWindow'

You should check the SVN logs, or at least the class header... ;)

In short : OpenGL states are no longer preserved by default (so the default behaviour is more intuitive), and you must call PreserveOpenGLStates if you want SFML to take care of external states.

So "OptimizeForNonOpenGL" is default now? Or what are you saying?

The default behaviour has changed from having 'PreserveOpenGLStates(true)' by default and calling it with false to turn it off to being 'PreserveOpenGLStates(false)' by default and requiring you to call the function if you want the functionality turned on.

Don't know what "PreserveOpenGLStates" means, but having the default value set to false means it's the same as when you used to set  OptimizeForNonOpenGL to true? I have never used OpenGL, I'm sorry if I'm slow :)

Default (preserve = false, or optimize = true) is OK for you if you don't use OpenGL.

It means that if you manage some OpenGL states on your side (ie. if you mix SFML rendering and OpenGL rendering), SFML won't mess them up with its own states.

Correct ;)

Ok, thanks, maybe there still is hope  :D
