Window / Re: Way to NOT pass reference to RenderWindow to a class?

If you want to draw to something then you have to pass this something to the function that does the drawing, I find this very natural and not annoying at all. And this is how everyone else does it too.

@Laurent thanks for feedback. I'll stick with passing the window then. I just thought that not doing it might have been better and I am apparently wrong.

Window / Way to NOT pass reference to RenderWindow to a class?

« on: May 07, 2016, 04:06:51 pm »

Greetings, people!

I am developing a video game using SFML and nearly every drawable entity has its own class. There is also a somewhat engine class, containing my RenderWindow.

The problem is that in order to call window's draw() method in any drawable entity's entity_draw() method, I have to either pass a window reference to the entity_draw() method, or have a reference as a member of entity's class and initialise it in a constructor, obvioulsy passing RenderWindow reference to the constructor.

Both variants are very annoying and I am wondering whether there is a good way to "globalize" the RenderWindow somehow.

The best solution I found was creating another class, containing only the window and a videomode(MainWindow class) so they could be accessible from any project file. These two were private static members and constructor and destructor were also private, so I got somewhat of a static class. This however produced an unresolved external symbol error and trying to initialise RenderWindow and VideoMode in different ways didn't produce any result.

Help? 
Thank you.
