Graphics / Re: Graphics slow to load

« on: December 31, 2013, 04:04:21 pm »

I researched what you said, but I'm still a little confused. I am using member variables and references, yet it still loads very slowly. Should I being changing something in the 07.cpp file? Thank you for the help by the way.

07.cpp

#include <SFML/Graphics.hpp>
#include "07.h"

int main() {

    sf::RenderWindow window(sf::VideoMode(800,600), "Objects");
    window.setFramerateLimit(45);

    sf::Event e;
    sf::Image p;
    p.loadFromFile("Bird.png");
    Bird b(p);
    sf::Texture tex;
    sf::Sprite sprite;
    tex.loadFromImage(b.getImage());
    sprite.setTexture(tex);

    while(window.isOpen()) {

        if(window.pollEvent(e) && e.type == sf::Event::Closed) window.close();
        window.clear(sf::Color::Black);

        window.draw(sprite);
       
        window.display();

    }

}

07 - Bird.cpp

#include "07.h"

sf::Image Bird::Image;

Bird::Bird(const sf::Image& i) {

    Bird::Image = i;

}

sf::Image Bird::getImage(){

    return Bird::Image;

}

07.h

#ifndef BIRD_H
#define BIRD_H

#include <SFML/Graphics.hpp>

class Bird {

        public:
                Bird(const sf::Image& i);
                sf::Image getImage();
        private:
                static sf::Image Image;

};

#endif

Thanks for the response. Did you mean like this? Same issue - very slow loading.

07.cpp

#include <SFML/Graphics.hpp>
#include "07.h"

int main() {

        sf::RenderWindow window(sf::VideoMode(800,600), "Objects");
        window.setFramerateLimit(45);

        sf::Event e;
        Bird b;
        sf::Texture tex;
        sf::Sprite sprite;
        tex.loadFromImage(b.getImage());
        sprite.setTexture(tex);

        while(window.isOpen()) {

                if(window.pollEvent(e) && e.type == sf::Event::Closed) window.close();
                window.clear(sf::Color::Black);

                window.draw(sprite);
               
                window.display();

        }

}

07 - Bird.cpp

#include "07.h"

sf::Image image;

Bird::Bird() {

        image.loadFromFile("Bird.png");

}

sf::Image Bird::getImage(){

        return image;

}

07.h

#ifndef BIRD_H
#define BIRD_H

#include <SFML/Graphics.hpp>

class Bird {

        public:
                Bird();
                sf::Image getImage();

};

#endif

Graphics / Graphics slow to load

« on: December 30, 2013, 11:21:55 pm »

I have a program that simply loads and displays an image in a window. I made the same program with all the code inside the main method and I had no problems with loading time. However, now that I've separated some parts into objects, the loading time for the image is at least 5 seconds. Before, it took less than a second. I just need some advice as to how to get this thing to load faster. Thanks.

07.cpp

#include <SFML/Graphics.hpp>
#include "07.h"

int main() {

        sf::RenderWindow window(sf::VideoMode(800,600), "Objects");
        window.setFramerateLimit(45);

        sf::Event e;
        sf::Image p;
        p.loadFromFile("Bird.png");
        Bird b(p);
        sf::Texture tex;
        sf::Sprite sprite;
        tex.loadFromImage(b.getImage());
        sprite.setTexture(tex);

        while(window.isOpen()) {

                if(window.pollEvent(e) && e.type == sf::Event::Closed) window.close();
                window.clear(sf::Color::Black);

                window.draw(sprite);
               
                window.display();

        }

}

07 - Bird.cpp

#include "07.h"

sf::Image image;

Bird::Bird(sf::Image i) {

        image = i;

}

sf::Image Bird::getImage(){

        return image;

}

07.h

#ifndef BIRD_H
#define BIRD_H

#include <SFML/Graphics.hpp>

class Bird {

        public:
                Bird(sf::Image i);
                sf::Image getImage();

};

#endif
