Failed to load image "". Reason : Unable to open f

[praetoriaen]

... is the error message I get after I run my program. I've checked the paths, they are ok, copied the images from their folder into the root of the program, even changed them from JPG to PNG and nothing... same error message for each image that is being loaded. It worked before in an other program, which was not much different from this one in terms of classes and such.
Here is the code:

main.cpp:

Code: [Select]


#include <iostream>
#include "kareninacharacter.h"
#include "blocks.h"
#include "mappings.h"

#define NAME "To heaven with you"


using namespace std;

int main() {

sf::RenderWindow *pApplication = new sf::RenderWindow(sf::VideoMode::GetMode(0), NAME, sf::Style::Fullscreen);

Blocks *pBackground = new Blocks(PLACEHOLDER);

kareninaCharacter *pPlayableCharacter = new kareninaCharacter(PLAYABLE_CHARACTER);

sf::Shape Floor = sf::Shape::Rectangle(0, 4800, 5000, 5000, sf::Color(50, 50, 50, 0)); //replace with Blocks

bool running = pApplication->IsOpened();

while(running)
{
sf::Event Event;

while(pApplication->GetEvent(Event))
{
if((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
{
pApplication->Close();
}
}

pApplication->Clear();


pApplication->Draw(pBackground->getSprite());

pApplication->Draw(Floor);

pApplication->Draw(pPlayableCharacter->getSprite());

pApplication->Display();
}

return 0;
}



mappings.h:

Code: [Select]


#ifndef MAPPINGS_H_
#define MAPPINGS_H_

#define PLACEHOLDER "placeholder.png"
#define PLAYABLE_CHARACTER "pc.png"

#endif


Also, the Blocks and kareninaCharacter class are pretty much the same, except the latter one has a few more methods, but the process of loading images and sprites is the same and as in the tutorial:

Code: [Select]


Blocks(string imglocation)
{

this->imgLocation = imgLocation;
Image.LoadFromFile(imgLocation);

Sprite.SetImage(Image);

}


I am using Visual Studio 2010 on Win7 x64

Bumping...

[Laurent]

The error message suggests that somehow your image filename is empty.

[praetoriaen]

The error message suggests that somehow your image filename is empty.

The only difference between this program and the program that worked, is that this program uses images created by myself, and the other one used images from the internet.

Can you provide a complete and minimal example that reproduces the problem?

Can you provide a complete and minimal example that reproduces the problem?

I'll post the whole code, without obfuscation:

He wanted less code, not more, keyword "minimal". Most of the time people don't have time to read through other people's code in details so you need to keep it brief if you have a chance of getting help.

My bad, didn't read thoroughly

Regarding the code, it works in my second "non-obfuscated" post, but it fails to do so in the first one, even though the code is 99% the same... sorry, this is the most minimal I can to reproduce the bug

[Laurent]

sorry, this is the most minimal I can to reproduce the bug

I don't think so
The most minimal that you can do is a main that loads and play the sound. Then if it works (which is what I expect), focus on the 1% of your code that is different between both versions. That should produce another minimal code, that you can debug much more easily than your whole project. Etc, etc....

People just give up when they face a bug that they can't explain immediately, like if there was nothing to do. But it's your code, you wrote it, and you wrote the bug too, so there's always something you can do to find it and fix it -- with some extra work. Don't be afraid to write or remove code just for debugging.

And if you happen to find a really minimal code that still has the problem, then I'll be able to tell you whether it's a bug in SFML or not.

I am sorry again for wasting your time. On the other hand, I think the problem is with Visual Studio 2010 project configurations... I'll just reset them and/or rebuild SFML
