Hi, I am implementing screen scrolling on my game (I imagine it will be easy, just using sf::Sprite::useSubRect()), but this isn't the main problem. My game has zombies that have a position x, y (relative to the window) and it has different sprites located in different locations. If I wanted my player to move around a big 2000x2000 map, how would I know what the position of my stuff is (relative to the top corner of the big 2000px map. ) And adjust my code which now uses co-ordinates in the screen?
