AO's forming a line from one object to another?

G'day all. I have some dragable objects in my app, and I also have a little 'marker' object. I need a line of these little marker objects from one dragable object to another.

Sounds simple enough, but when the user drags one of the dragable objects to a new position, I need the line of markers to follow - so that they're still forming a line from the origin (point A) to the new destination (point B). I'm afraid I don't have the mathematical knowledge to pull off a stunt like that! [crazy]

Any takers? :)

If the line you want is straight then the expression below can be used:

Set Marker X Position to:

X( "1" )+((X( "2" )-X( "1" ))/(NumberofMarkers+1))*Number( "Marker" )

Set Marker Y Position to:

Y( "1" )+((Y( "2" )-Y( "1" ))/(NumberofMarkers+1))*Number( "Marker" )
