Draw a line that follows an object

I don't know the best way. I would start like this (assuming my understanding of your need is even close)

1. Create the "line" object, either an open polygon or a single line segment (depending on your need), either by code or in the design.
2. Create the drawing object that you want to create the "line"
3. Create a function that is called whenever the drawing object is moved. It might either add points to the polygon or move the end of the line (depending on your need) based on the location of the moved object.
4. Call that function when the drawing object is moved. If it is moved by a script, call it there. If it is moved otherwise, choose a message to handle.
