Deleting RectangleShape pointer crashes window?

[ppsychrite]

Hello!
I'm starting to get into the feel of using pointers and attempted making a RectangleShape using them.
It worked, I was able to make it be displayed, but when I tried deleting it with a Keyboard event the Window proceeded to crash with "has stopped working"
Any reason this is happening and how to fix it?

int main() {
        RenderWindow window(VideoMode(800,600), "Game");
        window.setFramerateLimit(60);


        RectangleShape * Obj1 = new RectangleShape(Vector2f(40, 40));
       

        while (window.isOpen()) {

                Event event;
                while (window.pollEvent(event)) {
                        switch (event.type) {
                                case Event::Closed:
                                        window.close();

                                case Event::KeyPressed:
                                        if (Keyboard::isKeyPressed(Keyboard::Escape))
                                                window.close();

                                        else if (Keyboard::isKeyPressed(Keyboard::W))
                                                delete Obj1;

                        }

                }
                window.clear(Color::Red);
                window.draw(*Obj1);
                window.display();
               
        }
        return 0;
}

You are deleting the object, but you are still drawing it to the window after it gets deleted. This causes undefined behavior, and crashes the program.

Also I hope you are aware that it makes no sense in your code to dynamically allocate the shape. A stack variable will do just fine.
And finally, don't do manual memory management anymore. We have smart pointers now, so we should never have to write new and delete anymore.
