I am using SFML. I can't code the apples I need help. This is what I have but is totally wrong.

        int apple_x = (rand() +32)%752;
        int apple_y = (rand() +32)%552;

        if(rectangle.getGlobalBounds().intersects(apple.getGlobalBounds()))
        {
            apple.setPosition(apple_x, apple_y);
            window.draw(apple);
        }

        else
        {
            apple.setPosition(apple_x, apple_y);
            window.draw(apple);
        }

YES! Thank you so much!! But why putting this
RectangleShape apple;
apple.setSize(Vector2f(16,16));
apple.setFillColor(Color(250,0,0));
apple.setPosition(400,400);
in the beggining change anything?
Again thank you so much for the help
SweatyJuice (37)
Lol, ok thanks anyways :D

I cannot explain, because (to tell the truth) I know nothing about SFML.

The solution you gave doesn't actually have anything to do with SFML.
You moved the declaration of the variable outside the while loop so that the variable didn't get re-declared during every iteration of the while loop and thus the changes applied to the same instance of RectangleShape instead of a new version in every loop iteration.
