Why does my simple collision test with the screen not work?

[zombiekiller222]

                public virtual bool IsOnScreen()
                {
                        FloatRect rect1 = new FloatRect(Sprite.Position.X - Sprite.Origin.X, Sprite.Position.Y - Sprite.Origin.Y, Sprite.Width, Sprite.Height);
                        FloatRect rect2 = new FloatRect(Program.Camera.Center.X - Program.Camera.Viewport.Width / 2, Program.Camera.Center.Y - Program.Camera.Viewport.Height / 2, Program.Camera.Viewport.Width, Program.Camera.Viewport.Height);
                       
                        if (rect1.Intersects (rect2))
                        {
                                return true;
                        }
                       
                        else
                        {
                                return false;
                        }
                       
                }

I get that this is not the best or simplest way to do it, I've tried

return Sprite.SubRect.Intersects(Program.Camera.Viewport);

Yet that does not work (even if I convert the Sprite IntRect to a FloatRect).

I'm not exactly sure what your Program.Camera is.
You just need to make sure that both rectangles have absolute coordinates.

Keep in mind that the SubRect() of a sprite has nothing to do with it's position. It defines the show rectangle on the sf::Image which it holds. So you could make animations by first showing only a part of a image and then just move the subrect on the image to get another result.

Also I'd advise you to switch to SFML 2rc.

Switching to the RC now (how could you tell I wasn't using it?). Anyhow, Program is the main class, and Camera is a global variabe pointing to a Camera, basically my extension of a View.

EDIT: Wow, using this code I get 0 FPS.

return Program.Camera.Viewport.Intersects (Sprite.GetGlobalBounds ());

What is wrong?
