Moving a group of spline points

Hello,

I want to moving group of spline points by just moving one another point as parent controller.
In my example (see screenshot below), I want to control the Y position of all the point after the point 1by just moving the point 1 (using the point 1 like as a parent object)

def main():
    pline_object = op
    height = 800
    # set the points
    spline_object.SetPoint(0, c4d.Vector(0,0, 0))
    spline_object.SetPoint(1, c4d.Vector(0,height,0))

    obj_pnts = spline_object.GetAllPoints()
    for i in xrange(len(obj_pnts)):
        if i > 1 :
            # What do I make on: obj_pnts[i].y
            spline_object.SetPoint(i, c4d.Vector(obj_pnts[i].x, obj_pnts[i].y, obj_pnts[i].z))

Thank you.

I found the solution :

def main():
    pline_object = op
    height = 800

    # set the points
    spline_object.SetPoint(0, c4d.Vector(0,0, 0))
    #spline_object.SetPoint(1, c4d.Vector(0,height,0))

    obj_pnts = spline_object.GetAllPoints()
    for i in xrange(len(obj_pnts)):
        if i > 0 :
            interval = height - obj_pnts[1].y          
            spline_object.SetPoint(i, c4d.Vector(obj_pnts[i].x,obj_pnts[1].y+(obj_pnts[i].y-obj_pnts[1].y)+interval, obj_pnts[i].z))
                        

hello,

happy you found your solution, and thanks for the feedback

Cheers
