  Script help.

  I am trying to create a graphic that has lines that hug the 4 sides of a box. So as it scales in either direction the lines move with it automatically. Go here for an example

  i did this one by just keyframing it.
  So I was messing around with the position expressions of the lines.
  i came up with these.

  left line

  temp = thisComp.layer(“Royal Blue Solid 1”).position[0];
  [thisComp.layer(“Royal Blue Solid 1”).scale[0]*-3.6+360, position[1]]

  Bottom Line

  temp = thisComp.layer(“Royal Blue Solid 1”).position[1];
  [position[0], thisComp.layer(“Royal Blue Solid 1”).scale[1]*2.7+270]

  the other 2 are the same with negative numbers plugged in, so with these expressions, as i scale it, all the lines stay connected to the box.

  So here is my question, is there a way to adjust the expression so that the lines will also follow the box if i move it around the screen. Right now it works great as long as the box is centered on screen. As soon as i move it the lines stay where they are.

  Thanks

  What would be the drawback of “parenting” the lines to the box ..?
