This is not how SFML should be used.

Uhm, sorry again if this is a stupid question, but why should it not be used like that?

General / Trying to read the value of a sf::String causes crash

« on: August 16, 2016, 11:22:25 pm »

(Note : I'm still a beginner when it comes to programming, so sorry if it's something obvious)

So, when I try to print out the value of one of my function arguments of the type sf::String my entire application crashes with the error message ;

Exception thrown at 0x0FDE6D16 (msvcp140d.dll) in SwEngine.exe: 0xC0000005: Access violation reading location 0xCCCCCCCC.

If there is a handler for this exception, the program may be safely continued.

I believe  that a conversion between a std::String (which I send in to the function parameter of the type sf::String) fails, which leads to a crash, because when i try to use this sf::String value as a window title, the title is blank.

Here's some code :

This is the function which contains the sf::String value, and here's where the program crashes.

void Window::Create(unsigned int width, unsigned int height, sf::String title)
{

        std::cout << title.toAnsiString() << std::endl; // Crashes here.

}
 

And here's how I call that function :

Window::GetInstance().Create(1024, 720, globals::GAME_NAME);

And this is what the GAME_NAME variable is :

namespace globals
{

        // The name of the game the engine is currently running.
        const std::string GAME_NAME = "SwEngine Testing";

}
 

I'm pretty confused since it says in the SFML page that it handles conversions between the 2 string automatically, so, am I doing something very wrong here?

Graphics / Re: sf::Sprite is not a drawable?

The draw function accepts sf::Sprite, but not pointers to sf::Sprite. And i.second is a pointer to an sf::Sprite.
You need to dereference your pointer.

window->draw(*i.second);

I could have sworn I already tried that... But anyways, it worked! 
Thank you!

Also, new to this forum, do you know how accepting/marking an answer works?

Graphics / [SOLVED] - sf::Sprite is not a drawable?

« on: January 11, 2016, 06:58:54 pm »

So, currently I have this :

std::map<std::string, sf::Sprite*> sprites;

and I loop trough it like this :

        for (auto const& i : sprites)
        {
                window->draw(i.second);
        }
 

But when I try to run it, it tells me that :

illegal indirection
 void sf::RenderTarget::draw(const sf::Vertex *,size_t,sf::PrimitiveType,const sf::RenderStates &)': cannot convert argument 1 from 'sf::Sprite *const ' to 'const sf::Drawable &

Reason: cannot convert from 'sf::Sprite *const ' to 'const sf::Drawable'
No constructor could take the source type, or constructor overload resolution was ambiguous

Note :
I'm pretty new to both C++ and SFML so it might be obvious.
It might not even be a SFML problem.
