Draw Missing!?

[qsik]

i just updated to the latest SVN and for some reason my [window name].Draw function is missing!? what should i do?

[qsik]

nvmd, i needed a renderwindow instead of a window to draw images...when did that change?

[Laurent]

That never changed, there's nothing related to 2D graphics in sfml-window.

[qsik]

using VS 2008 + SVN version...its been awhile since ive used SFML

im getting a debug assertation, but im pretty sure im using the code right

i load the image here in the header file

Code: [Select]

int LoadImages()
{
if (!Opening.LoadFromFile("C:/Jeopardy/Other/Opening.jpg"))
return EXIT_FAILURE;

wrap up the function in the same file

Code: [Select]


int Load()
{
LoadImages();

then assign the image to a sprite in the main .cpp file

Code: [Select]

int main()
{
sf::RenderWindow App(sf::VideoMode(800, 600, 32), "Jeopardy!", sf::Style::Fullscreen);
Load();
OpeningImage.SetImage(Opening);

and display it after the event loop

Code: [Select]


App.Clear();
App.Draw(OpeningImage);
App.Display();

what am i doing wrong?

[Laurent]

What is the assertion message ? On which line is it happening ?

[qsik]

it happens when i get to the

Code: [Select]

App.Draw(OpeningImage);

breaking out of the program leads me to this section of code but points specifically to the line with _DEBUG_ERROR...

Code: [Select]

#if _HAS_ITERATOR_DEBUGGING
if (size() <= _Pos)
{
_DEBUG_ERROR("vector subscript out of range");
_SCL_SECURE_OUT_OF_RANGE;
}

error-debug assertation failed, line 779, vector subscript out of range

[Laurent]

Line 779 of which file ? Can you run it in debug mode and get the callstack ?

Basically, I'm almost sure there isn't any "out of range" error with vectors in SFML, so the problem might come from your code.

[qsik]

the file that breaking out of the program leads to is vector.h (the vc 2008 sdk file i think)

[Laurent]

Ok, I've found the bug. There's no protection when creating an OpenGL texture from an empty image, I'll fix this. By the way, this means one of your images failed to load.

[qsik]

failed to load due to a bug or due to my code?

[Laurent]

Should be due to your code, but apparently you properly handle loading errors. Unless you try to load a valid empty image

By the way, GIF is not a supported format.

[qsik]

that would explain it, all my images are gifs...

changing them to pngs should work then thnx

[qsik]

i changed them all to pngs but they still dont work! i get the same error, oddly my images wont bind to the sf::Image variables for some odd reason

[Laurent]

You should check the standard error output for any SFML message.

You should also use the value returned by your loading functions to actually do something useful when they report an error

[qsik]

my images are failing to load...is my code for loading images incorrect because i checked the path and it is correct
