Solved, didn't look far enough into http://www.sfml-dev.org/tutorials/2.0/graphics-vertex-array.php it fixed my problem

I have done that, but I haven't been able to get the drawing going. I've set the points, but It doesn't do it correctly, I cant see what i'm doing wrong.

Ok, I've got that working now, just I added it to my loops for my tile map, and it draws it all, but this happens.


This is the loop being to draw it, doing x*x instead of x+x crashes with a First chance exception.

        for (int x = 0; x < 250; x++){
                for (int y = 0; y < 250; y++){
                        sf::VertexArray lines(sf::Quads, 4);
                        lines[0].position = sf::Vector2f(x, y);
                        lines[1].position = sf::Vector2f(x, y+y);
                        lines[2].position = sf::Vector2f(x+x, y+y);
                        lines[3].position = sf::Vector2f(x+x, y);

                        lines[0].texCoords = sf::Vector2f(0, 0);
                        lines[1].texCoords = sf::Vector2f(0, 16);
                        lines[2].texCoords = sf::Vector2f(16, 16);
                        lines[3].texCoords = sf::Vector2f(16, 0);
                        window.draw(lines, &t_grass);
                }
        }
 

Did I type something wrong?
Cheers

Graphics / VertexArray displaying Dominant color, not the actual image

« on: April 06, 2014, 11:34:34 am »

Hi, I've recently learn't how to use VertexArray's as I read that it was much faster than loading each image individually.

I have my code for the VertexArray working, just when I goto load the image to display as a the 'tile' it shows the most dominant color used in the image, which is green, not the image.

Can you explain why it's doing this?

sf::Texture t_grass;//Called when program is initialized

        while (window.isOpen()){
                sf::Event event;
                while (window.pollEvent(event)){
                        if (event.type == sf::Event::Closed)
                                window.close();
                }
                t_grass.loadFromFile("images/grass.png");//Loads the image
                window.clear();

                sf::VertexArray lines(sf::Quads, 4);
                lines[0].position = sf::Vector2f(0, 0);
                lines[1].position = sf::Vector2f(0, 50);
                lines[2].position = sf::Vector2f(50, 50);
                lines[3].position = sf::Vector2f(50, 0);
                window.draw(lines, &t_grass);
                window.display();
        }
 

The image loads fine, so I'm lost with all of it.
Cheers
