Default value
0
This displaces the object’s icon horizontally by the specified number of pixels. This is meant to be used in situations where world.map_format is used to display something other than a top-down form, for instance in an isometric or side-view display. In a top-down mode pixel_w behaves the same as pixel_x, except that it does not rotate with changes to client.dir.
This effect is purely visual and does not influence such things as movement bumping or view() range calculations.
