tardy shoal
#

welp, looks like it should work

analog mango
#

oh

#

is it the colour

tardy shoal
#

why?

#

youre setting the colour of the circle to white

#

and the background to black

#

should work

analog mango
#

i have tho

#

imma put some prints in

tardy shoal
#

not sure how thats going to help but okay

#

you should consider just debugging

#

if youre going to print

analog mango
#

yh that is for my debugging im probably a bit dumb to say this but i have never used the debugger

#

found something

i have an idea

//i like put these things here not in the constructor

struct Ball
{

    sf::CircleShape circle;
    float x, y, radius;
    sf::Color color;

    Ball(int width, int height)
    {
        x = width / 2.f;
        y = height / 2.f;

        radius = 50.f;
        circle.setRadius(radius);
        color = sf::Color::White;
        circle.setFillColor(color);
        circle.setPosition(sf::Vector2f(x, y));
    };
};

circle.getPosition() and i dont know about the rest, one thing you can do is to move them out of constructor body and make them members.

analog mango
#

did i like make them members here
