0 is the first management number. If this is your first and only sprite, do 0. If you have a second sprite at the same time, do 1. Up is 1, down is 2, left is 4, and right is 8. It's better this way since you can press up and left together to make 5 and the computer will know. If it were 1,2,3,4 then up+left would be the same as pressing right, and that's no good. Go look up Vsync.
