Trouble creating an SFML Window

Time:05-30

When trying to create an SFML window, sf::VideoMode(800, 600) gives a constructor not viable error.

Source code:

#include <SFML/Window.hpp>

int main() {
    sf::Window window(sf::VideoMode(800, 600), "Pong");

    return 0;
}

To my understanding and from the tutorials I've read/watched, this is the standard way of creating a window. I can successfully create the window using a sf::Vector2<unsigned int> however from looking at the SFML tutorials, this doesn't appear to be necessary.

Is this just the new way? Or am I missing something?

CodePudding user response:

Is this just the new way?

Yes, they have made some changes.

Here are the changes from the source file:
This:

VideoMode(unsigned int modeWidth, unsigned int modeHeight, unsigned int modeBitsPerPixel = 32);

is now this:

explicit VideoMode(const Vector2u& modeSize, unsigned int modeBitsPerPixel = 32);

Take a look at it here.
