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.
