reason for the & sign
« on: July 04, 2014, 08:29:10 pm »
I created a function that looks like this:

void Draw(sf::RenderWindow &window);

... to draw a sprite.

but I don't understand why the & sign needs to be there...
what is it for? I can't seem to find out

It marks the variable as being a reference.
