A 3*3 grid, consisting of 9 squares (0-0, 0-1, 0-2, 1-0, 1-1, 1-2, 2-0, 2-1, 2-2). I want to be able to navigate the grid using a keyboard by going up, down, left and right. If I hit the edge of the grid, I would like to “wrap” to the other side. This kind of menu is seen on games, mobile devices etc.
Does anyone have a good implementation of navigation algorithm (does not to be in AS3), rather something I can refer to? Also, does anyone know the name of such menus so I can search for it?
