Hi i need some help on knowing how to make a 2d style rpg game engine in vb. i know vb is stupid for games and i wouldnt generally do it in vb but its for school and i want to so yea can someone give me an idea of what id have to include? for example: how i would make him walk on key pres but only a certain distance; how i would make a room that was bigger than the window size and make the man walk around and the window follow hima round the room?
