C++ Drawing to the screen

SFML

This method will require you to install some packages. In Visual Studio, and Project, select 'Manage Nuget Packages'.

Click the browse tab and type:

'sfml'

Now look for the version numbers, each version has a slightly different name. I have found:

SFML has 5 different components, so click each one and click install.

Creating A Window

The code below will create a window, and also provides a loop to keep the window open and to check for window events:

#include <SFML/Graphics.hpp>

int main()
{
	sf::RenderWindow window{{ 800, 800 }, "Window Title"};
	window.setFramerateLimit(60);

	while (window.isOpen())
	{
		sf::Event event;
		while (window.pollEvent(event))
		{
			if (event.type == sf:: Event::Closed)
			{
				window.close();
			}
		}
		window.clear();
		window.display();
	}
}

Drawing a Rectangle

We can declare a rectangle, so after the 'window.setFramerateLimit(60)' line add:

		sf::RectangleShape rectangle{ { 220.f, 160.f } }; 
		rectangle.setFillColor(sf::Color::White);
		rectangle.setPosition({ 150.f, 20.f }); 
		rectangle.rotate(20.f);

Now in between the 'window.clear()' and the 'window.display()' enter the following line to draw the rectangle:

window.draw(rectangle);

Drawing a Circle

We can declare a circle, so after the 'window.setFramerateLimit(60)' line add:

		sf::CircleShape circle{ {100.f } }; 
		circle.setFillColor(sf:: Color{ 0x006495FF }); //another way to set a color
		circle.setOutlineColor(sf:: Color{ 224, 160, 37, 255 }); //yet another way to set a color
		circle.setPosition({ 300.f, 3950.f }); 
		circle.setOutlineThickness(5.f);

Now in between the 'window.clear()' and the 'window.display()' enter the following line to draw the circle:

window.draw(circle);
