Global blur

[soaup]

Hello and sorry for bad english! I had tried implement blur on all game screen, to visualize game pause. For this i call RenderWindow::capture() by pressing key, and draw captured image. But capture() it takes too much time. And call window->draw(spritem &shader) for all objects it leads to the fact that all the sprites with blur look different. Please answer - how to make global blur?

Did you try to use a RenderTexture instead of capture?

Draw everything you have to a RenderTexture instead of a RenderWindow and then draw a Sprite with that RenderTexture and your blur.

Probably the better way to implement blur is shaders, it will looks much better with dynamic effects
