Graphics / [Solved]Shape objects as class member not drawing?

« on: December 28, 2021, 12:09:37 pm »

I found that drawable objects(such as CircleShape, VertexArray...etc) cannot be drawn if they are class member. What is going wrong? Is there a problem in constructing a object?

I'm using:
SFML 2.5.1
GCC 7.3.0

This is an simple example regards the problem.

#include <SFML/Graphics.hpp>

class Class{
        public:
        sf::CircleShape circle;
        Class(){
                sf::CircleShape circle(100.f);
        }
        void main(){
                sf::RenderWindow window(sf::VideoMode(640,480),"Title");
                while(window.isOpen()){
                        sf::Event event;
                        while(window.pollEvent(event)){
                                if (event.type == sf::Event::Closed) window.close();
                        }
                        window.clear(sf::Color::Black);
                        window.draw(circle); // This does not draw
                        window.display();
                }
        }
};
int main(){
        Class clazz;
        clazz.main();
       
        sf::RenderWindow window(sf::VideoMode(640,480),"Title");
        while(window.isOpen()){
                sf::Event event;
                while(window.pollEvent(event)){
                        if (event.type == sf::Event::Closed) window.close();
                }
                window.clear(sf::Color::Black);
                window.draw(clazz.circle); // This doesn't draw either
                window.display();
        }
}
