Graphics / Re: custom shape type not appear in window

« on: January 07, 2015, 08:53:55 am »

#include <SFML/Graphics.hpp>

int main()
{
sf::RenderWindow window(sf::VideoMode(1280, 720), "This is the title");


class EllipseShape : public sf::Shape
{
public :
    explicit EllipseShape(const sf::Vector2f& radius = sf::Vector2f(0, 0)) : m_radius(radius)
    {
        update();
    }

    void setRadius(const sf::Vector2f& radius)
    {
        m_radius = radius;
        update();
    }

    const sf::Vector2f& getRadius() const
    {
        return m_radius;
    }

    virtual unsigned int getPointCount() const
    {
        return 30; // fixed, but could be an attribute of the class if needed
    }

    virtual sf::Vector2f getPoint(unsigned int index) const
    {
        static const float pi = 3.141592654f;

        float angle = index * 2 * pi / getPointCount() - pi / 2;
        float x = std::cos(angle) * m_radius.x;
        float y = std::sin(angle) * m_radius.y;

        return sf::Vector2f(m_radius.x + x, m_radius.y + y);
    }
private :

    sf::Vector2f m_radius;
};


    while (window.isOpen())
    {
         sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        window.clear();
        window.draw(/*What goes here?*/);
        window.display();
        }
    }
    return 0;
}

This is the code, mostly just what is on the tutorial.
I mainly think i am just missing window.draw(??)
I tried EllipseShape, shape, then just tried everything else i could think of

Graphics / custom shape type not appear in window

« on: January 06, 2015, 02:23:44 pm »

Hi. Just started programming. I have gone from c++ to winapi and now SFML
In the 2.2 tutorial for Shapes
Working through the tutorials one by one
 
http://www.sfml-dev.org/tutorials/2.2/graphics-shape.php

For bottom section about Custom shape type

My code manages to compile, but the shape isn't appearing

I thought maybe i was missing
window.draw()
because i did forget a few times during other parts
but I can't figure out what goes into the parentheses here

Any help is much appreciated
