I am basically trying to create a simple scrolling tilebased map, but the map is going to be HUGE! It will only be involve horizontal scrolling. I am wondering what is the best way to store and load in a large amount of variables. Should I go with XML? I would also like to be able to devise a system where people couldn't steal my map data, either from wherever I host the XML file or from the game itself. Is this possible? And if so, what steps do I need to take?
