Title: Stack around the variable "MyFont" was corrupted.
Post by: scyth3s on May 18, 2011, 04:58:40 pm

I have this code, which, for test purposes, I copied and pasted directly from the 1.6 tutorial.

Code: [Select]


     sf::Font MyFont = sf::Font::GetDefaultFont();

// Create a graphical string
    sf::String Hello;
    Hello.SetText("Hello !\nHow are you ?");
    Hello.SetFont(MyFont);
    Hello.SetColor(sf::Color(0, 128, 128));
    Hello.SetPosition(100.f, 100.f);
    Hello.SetRotation(15.f);
    Hello.SetSize(50.f);

And I get the runtime error in the title bar. I've tried having SFML load Xirod font, which I put in the project folder (VS 2010) and the executable folder. No dice.

Do NOT use the default font. Last I checked, it's completely broken and results in errors. It might just be a specific version of SFML, though.

The default font should work fine. But maybe it's the copy that is broken, try to get a reference on the default font instead of copying it.

That's odd. Isn't it just a copy of the Arial font? Should I always provide a font file instead? Sorry for the thread-hijacking, just curious.

I also tried loading Xirod TTF. Is there a specific spot on my hard drive it must be in?

As in sf::Font &MyFont = sf::Font::GetDefaultFont(); ?

I have tried both of these, and neither lent any dice. Linking with the debug libraries has yielded nothing as well.

Some more code snippets:

Code: [Select]

GButton.h
/////////////////////
/// The font that the button class will use
/////////////////////
const sf::Font *font;

Code: [Select]

GButton.cpp
GButton::GButton(sf::RenderWindow& window, std::string text, sf::Color selectedColor, sf::Color deselectedColor)
{
//set the render window
this->window = &window;

//set the colors
this->selectedColor = selectedColor;
this->deselectedColor = deselectedColor;

//reference to the default font
font = &sf::Font::GetDefaultFont();
this->text = sf::String(text, *font, 30);
}


Code: [Select]

GButton.cpp
void GButton::Draw()
{
window->Draw(text);
}


I couldn't get a module level const variable reference to compile, so I tried a pointer. Still the same runtime error. However, I did notice that no matter what I do, the font for the sf::String 'text' seems to have an invalid size

Would a minimal example (just a window, the font and a text) still reproduce the error? If so, copy it there and I'll test it.

I did some digging, and apparently, SFML was/is buggy with VS2010? I compiled my project in VS2008 and it worked all fine and dandy.

The VC2008 libs are not compatible with VC2010, you must recompile SFML to use it with VC2010.

AHA! This solved it. I never read about compiling it myself before! Interesting that it never caused me any issues until that text thing.
