Sprite won't draw correctly

[matt2224]

Code: [Select]

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow App(sf::VideoMode(800, 600, 32), "SFML 2D");
    sf::Image image;
    sf::Sprite sprite;

    image.LoadFromFile("tree.tga");
    sprite.SetImage(image);

    while (App.IsOpened())
    {
        // Event handling
        sf::Event event;
        while (App.GetEvent(event))
        {
            if (event.Type == sf::Event::Closed)
                App.Close();
        }

        glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
        glClear(GL_COLOR_BUFFER_BIT);
       
        App.Draw(sprite);
        App.Display();
    }

    return 0;
}


Tree.tga:

Why won't it work?

I'm unable to see your images (imageshack is blocked at my office), but :
- Use App.Clear() instead of openGL functions
- Verify the LoadFromFile return : is the image loaded correctly ?

[matt2224]

I'm using the OpenGl functions because App.Clear() crashes the program (other people have mentioned this in here before).

The image is loaded correctly, I've just tried checking the return. I'll try and upload the image at a different host if it helps.

Thx a lot, but there is a lot of websites blocked, even tinypic

By the way :
- SFML version ?
- IDE ?
- OS ?

Can you explain with words what is bad on the image ? (tonight I will be able to see them )

[matt2224]

Basically, I have this huge box in the corner with a green-light green gradient. I though it was the sprite but massively upscaled, but if I try to scale it down again it disappears completely.

OS: Ubuntu 10.04
IDE: Qt Creator, but even when I compile manually it doesn't work

How do I find out my SFML version?

Well, when you installed it, you had to choose a version, no ?
Did you recompile it ? Seems no.

[matt2224]

It's version 1.5

[Mindiell]

Ok, using openGL command salterate the render with SFML.
Use PreserveOpenglState

It doesn't matter, glClearColor has an effect only on glClear, it changes nothing for SFML.

Any ideas Laurent?

[Laurent]

What graphics card do you have? Are your drivers up-to-date? Can you run other OpenGL applications?

[matt2224]

Yes. The other tutorial with the 3D rotating cube worked fine.

[Laurent]

What if you use another image (like one from the samples)?

[matt2224]

Nope. I've already tried a multitude of images.

[Laurent]

Do the SFML samples work?
