put pivot to centre of object and X - 0

thx

This will works for selection of objects.

(
	if selection.count != 0 do with redraw off
	(
		CenterPivot selection
                selection.pivot.x = 0
                -- if you want to use a loop
		-- for o in selection do o.pivot.x = 0
	)
)

sorry..yes. world X position i meant

What X - 0 means?
World X or something else?
Can you show a picture?

-- put the object's pivot to objhect's center
centerPivot selection[1]
-- move the object's pivot to world X = 0
selection[1].pivot.x = 0
