help setting fullscreen resolution with view.

[Elgan]

Hello,

In window mode, I create the window, then I can scale it with setsize, and it scales the internal view perfectly. Allowing me to initially create a window to the size of my background and images, then have them all scaled up. In full screen mode I am struggling to do the same.

Here is my code;

Code: [Select]

int main()
{
sf::Texture texBack;
texBack.LoadFromFile("introback.bmp");
sf::Sprite sprBack;
sprBack.SetTexture(texBack);

//current video mode
sf::VideoMode DesktopMode = sf::VideoMode::GetDesktopMode();

    // Create the main rendering window
sf::RenderWindow App; //(sf::VideoMode(320, 224, 32), "SFML Graphics", sf::Style::None);
sf::View view;
App.Create(sf::VideoMode(320, 220, DesktopMode.BitsPerPixel), "SFML Graphics", sf::Style::None);
view = App.GetView();
//App.Create(sf::VideoMode(DesktopMode.Width / 2, DesktopMode.Height / 2, DesktopMode.BitsPerPixel), "SFML Graphics", sf::Style::Fullscreen);
App.Create(sf::VideoMode(DesktopMode.Width, DesktopMode.Height, DesktopMode.BitsPerPixel), "SFML Graphics", sf::Style::Fullscreen);
[color=red] view.SetSize(320 * 2, 220 * 2);
view.SetCenter(320 , 220 );
App.SetView(view);[/color]

    // Start game loop
    while (App.IsOpened())
    {
        // Process events
        sf::Event Event;
        while (App.PollEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();
        }

        // Clear the screen with red color
        App.Clear();

App.Draw(sprBack);
        // Display window contents on screen
        App.Display();
    }

    return EXIT_SUCCESS;
}



The image is 320, 220, and I want it, so when I go to full screen, it scales with the window, no matter what resolution.

now I can not get it to do this, it always just rebuilds the view and my background is tiny,

UNLESS... I add these

Code: [Select]


[color=red] view.SetSize(320 * 2, 220 * 2);
view.SetCenter(320 , 220 );
App.SetView(view);[/color]


320 * 2 is not even my monitor res.....which is 2560x1440

which make no sense to me? and mess up window sizing anyway.

Also if I want to place a sprite at the edge of the window...should I use ;

   return Window.ConvertCoords(Window.GetWidth() , Window.GetHeight());

or the view size?

[Elgan]

Any ideas?

so I can set it up like so for windowed mode (which works anyway)

Code: [Select]

App.Create(sf::VideoMode(DesktopMode.Width , DesktopMode.Height , DesktopMode.BitsPerPixel), "SFML Graphics", sf::Style::Fullscreen);
view = App.GetView();
//App.Create(sf::VideoMode(DesktopMode.Width , DesktopMode.Height, DesktopMode.BitsPerPixel), "SFML Graphics", sf::Style::Fullscreen);
view.SetSize(640 ,480 );
view.SetCenter(640 / 2 ,480/ 2  );
App.SetView(view);
//

    // Start game loop
    while (App.IsOpened())
    {
        // Process events
        sf::Event Event;
        while (App.PollEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();

// Resize event : adjust viewport
if (Event.Type == sf::Event::Resized)
{
//glViewport(0, 0, 640, 480);
view = App.GetView();
//App.Create(sf::VideoMode(DesktopMode.Width , DesktopMode.Height, DesktopMode.BitsPerPixel), "SFML Graphics", sf::Style::Fullscreen);
view.SetSize(640 ,480 );
view.SetCenter(640 / 2 ,480/ 2  );
App.SetView(view);
}
        }

        // Clear the screen with red color
        App.Clear();

App.Draw(sprBack);
        // Display window contents on screen
        App.Display();
    }

    return EXIT_SUCCESS;
}



Setting the rest, and then setting the view to the size of the image.

BUT the image is too big for the screen when I do this....what?! surly it should be fine? it makes no sense to me? the image should thus match the view

Code: [Select]


sf::Vector2f CGameEngine::GetSize()
{
return Window.ConvertCoords(Window.GetWidth() / 2 , Window.GetHeight() / 2);


The above returns place my sprites exactly where I want them :\

i still really need some help on this guys

Code: [Select]



Window.Create(sf::VideoMode(DesktopMode.Width , DesktopMode.Height , DesktopMode.BitsPerPixel), "SFML Graphics", sf::Style::Fullscreen);
sf::View view;
view = Window.GetView();

view.SetSize(640  , 480  );
view.SetCenter(640 /2 , 480 / 2);


Window.SetView(view);



how can i set it up, so that my 640x480 image is fullscreen?

windows-no problem.
fullscreen - image is zoomed in, never right.

It may be that your monitor is showing only a fraction of the screen for the resolution you are trying to use. Try to mess with its options and see if there was something hidden.

[Elgan]

been messing about for ages now.

Code: [Select]

//Window.Create(sf::VideoMode(DesktopMode.Width / devide, DesktopMode.Height / devide, DesktopMode.BitsPerPixel), "SFML Graphics", style);
Window.Create(sf::VideoMode(DesktopMode.Width , DesktopMode.Height , DesktopMode.BitsPerPixel), "SFML Graphics", sf::Style::Fullscreen);


should be "my screen size" though, right?

edit:

but, even:    Window.Create(sf::VideoMode(800, 600  , DesktopMode.BitsPerPixel), "SFML Graphics", sf::Style::Fullscreen);


doesnt show the 800x600 pic properly.

-going to try a minimal again, but I'm sure I had the same problems before (code first,2nd post)

[Ptlomej]

If view.SetSize(640 ,480 ); everytime equal the window size then the view is correct and you dont have resized images or background or anything else.

[Elgan]

sorry , I don't understand?

[Tex Killer]

Elgan, I meant for you to mess with your monitor options.

[Elgan]

Elgan, I meant for you to mess with your monitor options.

tried that too, thank you tho :\

I cant make em bigger though, 2550x1440

[Elgan]

still stuck
