Hello, I’m working on a game and I want the background of the game to move or the view of it at least. I know that it is possible to create the image and have it move left and right, but for larger images this can create lag since it’s moving such a large movie clip. If I were to use a mask the size of the viewing window, would it keep the whole background from being drawn and save on processor? Is there any other method for handling this efficiently? Thanks.
