Graphics / Loading a TFF with sf::Font and rendering in 3D with OpenGL?

« on: August 12, 2011, 01:31:03 pm »

Would you be able to add the ability to render sf::Text without preserving states or whatever.

So that we could render it at a 3D location, or a 2D location on the screen but at any point during our OpenGL drawing.

I'm simply only using SFML for window management, input and fonts. Thanks a bunch.

Graphics / Loading a TFF with sf::Font and rendering in 3D with OpenGL?

« on: July 24, 2011, 02:13:05 pm »

Is this possible? How would I go about doing it. My reasoning for this is that I'd rather use SFML's font loading for TTF's than write my own or get some other external lib.

Thanks!

Window / Window.GetFrameTime is returning strange values

Sorry, this was an unexpected change! Thanks a lot man!

Window / Window.GetFrameTime is returning strange values

« on: July 24, 2011, 01:46:19 pm »

I've recently upgraded SFML2 to the latest revision and now my simultation runs extremely fast and GetFrameTime returns "15" - "16" so when I calculate FPS by doing 1.0f / GetFrameTime() I'm getting "FPS" of 0.0666666667 so as you can tell something is seriously wrong.

I've still doing SetFramerateLimit(60.0f)

I have a project due in Tuesday at uni so I hope you can help!

Thanks!

Fixed by this:

Code: [Select]


static T* m_pInstance =  0;
if (!m_pInstance)
m_pInstance = new T;

return m_pInstance;


(Creating it on the heap).

Thanks for your help!

Okay yeah the "magic static place" is causing the crash, any ideas?

Code: [Select]


#include <SFML/Graphics.hpp>

class Test
{
public:
static Test* Instance();
Test() {};
~Test() {};
void Blah();
sf::RenderWindow m_window;
};

Test* Test::Instance()
{
static Test* test;
return test;
}

void Test::Blah()
{
m_window.Create(
sf::VideoMode(800, 600, 32), "Game",
sf::Style::Titlebar | sf::Style::Close
);
}

int main()
{
Test* lol = Test::Instance();

while ( lol->m_window.IsOpened() )
{
sf::Event windowEvent;

while ( lol->m_window.PollEvent(windowEvent) )
{
if (windowEvent.Type == sf::Event::Closed)
lol->m_window.Close();
}

lol->m_window.Clear();
lol->m_window.Display();
}

return 0;
}

~Test() {};
void Blah();
sf::RenderWindow m_window;
};

void Test::Blah()
{
m_window.Create(

sf::Style::Titlebar | sf::Style::Close
);
}

int main()
{
Test lol;

lol.Blah();

while ( lol.m_window.IsOpened() )
{
sf::Event windowEvent;

while ( lol.m_window.PollEvent(windowEvent) )
{
if (windowEvent.Type == sf::Event::Closed)
lol.m_window.Close();
}

lol.m_window.Clear();
lol.m_window.Display();
}

return 0;
}


Works fine... so could it be that storing sf:: objects such as RenderWindow or Image within a class that is stored in the "magic static place" e.g: my singleton Engine class causes the crash/memory violation error?

If so, can this be fixed?

Does the following code produce the same crash?

Code: [Select]

#include <SFML/Graphics.hpp>

int main()
{
    sf::Image image;
    image.Create(10, 10);

    return 0;
}

Nope, like I said my problem seems to be when sf::Image is a class member variable.

Which revision of SFML 2 are you using?

LaurentGomila-SFML-df68742 (SFML 2.0 Snapshot)

but to re-iterate I had the same problem with SFML 1.6.

Okay, let me clear a few things up:

- I've compiled for VS 2010, and am dynamically linking.
- I have all the VS 2010 compiled .dlls in the distro dir.
- I have all the VS 2010 compiled .libs linked to the project.
- I am only linking to debug libs in Debug mode, and same for release.



I have tried with both 1.6 and 2.0. I can get everything to compile and run fine, I have my window, and my 3D OpenGL cubes and spheres spinning about contently.

However:

When I want to have, say, an sf::Image as a member variable of a class (Engine, in the above picture), and then I call something like... say... LoadFromFile on it, I get an unhandled exception/access violation error when I run the executable.





Please help me somebody, I need to get this working ASAP for my university course and I'm tearing my hair out.

It would do the same thing if it were an sf::RenderWindow I was to have as a member variable.

Please don't moan at me for not searching the forum, or Google, because I assure you I've been searching the net for the past 4 hours straight and I have like 28 tabs open because of it. Yet I haven't fixed my problem.

Thank you.
