Your question is still related to Joel's answer. A region is located inside of a bitmap and cannot extend beyond the bounds of its bitmap. So your regions x and y positions would reflect the positions you created the region at. If you offset your region then those coordinates will change inside of the bitmap. Now a sprites x and y are where you locate it on the screen. It has nothing to do with the regions x,y. Like taking a picture of a landscape. The picture is a region or portion of the landscape and the Sprite would be the picture frame that you can hang anywhere on the wall. The pictures x y is where you took the picture in relation to the landscape. The sprites x,y is the location you hung the picture on the wall
