Graphics / SFML2 rendering sprites fail.

« on: June 22, 2011, 07:49:19 pm »

honestly, I get this issue all the damn time. what in the hell do i have to do to get a sprite on the screen every single time! i just get a white block of whats supposed to be the image. yes i've used sfml before and this issue is random. some projects i have them working fine. this they dont.

heres the code:

Code: [Select]



#include <SFML/Graphics.hpp>
#include"Background.hpp"

int main()
{
    // Create the main window-width, hieght
    sf::RenderWindow window(sf::VideoMode(800, 600), "Connect 4");

    window.SetFramerateLimit(15);
    //load images
    sf::Sprite background(Background::Load("Data/background.bmp"));
    background.Move(200,200);
    // Start the game loop
    while (window.IsOpened())
    {
        // Process events
        sf::Event event;
        while (window.PollEvent(event))
        {
            // Close window : exit
            if (event.Type == sf::Event::Closed)
                window.Close();
        }

        // Clear screen
        window.Clear();

        window.Draw(background);
        // Update the window
        window.Display();
    }

    return EXIT_SUCCESS;
}


all background does is return the sprite loaded.

Code: [Select]


sf::Image Background::Load(string filename)
{
    sf::Image image;

    if( !image.LoadFromFile(filename) )
    {
        //fail
    }
    else
    {
        return image;
    }
}

General discussions / The Concept of Screen moving [2d camera]

« on: June 10, 2011, 05:46:27 pm »

Hello, i've been wondering this but i can seem to get a hold of the concept of programming a 2d platformer. jumping and maps dont seem to be the problem its just the screen( or camera) moving i dont understand. can someone break down the theory of this. do i need an offset, becasue i heard one way of doing it is basically the character doesnt move at all but you essentially moving the map itself.
