displaying images in sfml

step 1
first of all you need to install SFML. I am using kali linux and i found the linux installation guide here.

step 2
next you need to make a window i made a guide here but i will give you the code anyway. Enter this code into your preferred text/code editor:

#include <SFML/Graphics.hpp>

int main()
{
    // create the window
    sf::RenderWindow window(sf::VideoMode(800, 600), "Hello window!");

    // run the program as long as the window is open
    while (window.isOpen())
    {
        // check all the window's events that were triggered since the last iteration of the loop
        sf::Event event;
        while (window.pollEvent(event))
        {
            // "close requested" event: we close the window
            if (event.type == sf::Event::Closed)
                window.close();
        }

        // clear the window with black color
        window.clear(sf::Color::Black);

        // draw everything here...
        // window.draw(...);

        // end the current frame
        window.display();
    }

    return 0;
}

then check that the window will display by compiling it with:g++ main.cpp -o main -lsfml-graphics -lsfml-window -lsfml-system and run it with: ./main

step 3
first you will need to find an image to use. i will be using this one:

step 4
now we will implement the code. this is what the code for displaying the image on the window should look like:

note: on line 8 change the Mushroom.png to your file of choice.

#include <SFML/Graphics.hpp>
#include <iostream>

int main(){
        int x = 100;
        int y = 100;
        sf::RenderWindow window(sf::VideoMode(800, 600), "Hello Window");
        sf::Texture texture;
        if (!texture.loadFromFile("Mushroom.png")) {
                std::cout << "Could not load enemy texture" << std::endl;
                return 0;
        }
        while (window.isOpen()) {
                sf::Event event;
                while (window.pollEvent(event)) {
                        if (event.type == sf::Event::Closed)
                                window.close();
                }

                window.clear(sf::Color::Black);

                sf::Sprite image;
                image.setTexture(texture);
                image.setPosition(sf::Vector2f(x,y));
                image.scale(sf::Vector2f(1,1.5));
                window.clear();
                window.draw(image);

                window.display();

        }

        return 0;
}

step 4
we will compile this by doing: g++ -o main main.cpp -lsfml-graphics -lsfml-window -lsfml-system and then run it with: ./main

step 5
enjoy and have a good day.
