Okay so using the debug libraries fixed it, thank you.

Also thank you Raphman for pointing out that i was loading the texture too often ^^

Well yeah i feel like a bit of an idiot for not realising that simply changing the colour doesn't do anything if there is no texture loaded.

When I run the code, attempting to load the texture, it breaks at the line:

if (!grass.loadFromFile("Grass.png"))

with the error:

"Unhandled exception at 0x71521f34 in First SFML work.exe: 0xC0000005: Access violation reading location 0x00304000."

I have the image, with the correct name, of course, in the debug folder for the project (Visual Studio 2010\Projects\First SFML work\Debug) which I believe is the correct place but just incase also stored it in the folder (Visual Studio 2010\Projects\First SFML work\First SFML work) as well.

Having looked at other forum posts I don't think this is a coding error but something to do with how i've set up SFML or where I've stored the image. However the only similar errors i can see have been when loading audio, not textures, if that's of any consequence.

Graphics / Why are my tiles not displayed?

Hi, I'm really new to SFML and objects and classes so please bare with me ^^.
I'm trying to just get started and display a set of 32x24 tiles depending on the value of the grid. My problem is that the sprite's just aren't displayed.

I know that the array 'grid' is full of 'G's so that shouldn't be a problem. SIZEX and SIZEY are both 10.

and as an added extra can anybody tell me why I get an unhandled exception error when I try to load from file ^^

Thanks.

void displayFloor(char grid[][SIZEY], sf::RenderWindow& window)
{
        sf::Texture grass;
        //if (!grass.loadFromFile("Grass.png"))
        //{
        //      cout << "Can't load grass";
        //}
        sf::Sprite grassSprite;
        //grassSprite.setTexture(grass);
        grassSprite.setColor(sf::Color(50, 255, 50, 0));
        grassSprite.setScale(32,24);
        for( int row(1); row<=SIZEY; ++row )
        {
                for( int col(1); col<=SIZEX; ++col )
                {
                        float x = 0 + col * 32;
                        float y = 0 + row * 24;
                        switch( grid[row][col] )
                        {
                        case 'G':
                                grassSprite.setPosition( x, y );
                                window.draw( grassSprite );
                                break;
                        }
                }
        }
}
