So I'm trying to figure out what your expression means:

X Position: You limited the object's horizontal movement or position on the x-axis to a minimum of half of the object's width and a maximum of the layout's width subtracting half of the object's width.

Min: Half of object's width = 38
Max: Layout's width (640) - 38 = 602

The object's movement is limited to a minimum of 38 and a maximum of 602 on the x-axis?

Sorry if I don't really understand. ;XTokki2012-02-29 00:46:26

'cause the image point is at the center of the sprite. If I don't offset things by half the width and half the height you will have half the sprite out of layout. But maybe it's not a problem for you (:

Ooh, the image point is taken into consideration in the expression as well.

So if it was on a grid, the object can only move between those two values?

(I'm a super noob, so I need the dumbed-down explanation. *blushes*)

Since the origin of your image (its x and y coordinates) is centered, if you add or remove half of its width to its x coordinate you get the coordinate of the left/right border of the object.
This way, staying in the range (38, 602), you are sure that your image sticks to the boundaries of the screen horizontaly.
Same logic verticaly.
