Your startAnimation function reads through a line called "poly" (if
I've understood it right).
Change that to polys[lineNumber] so that it uses one of the lines you
have in the array, assuming you called it "polys" as suggested. It may
be referenced in several places.
Change the function definition to include that lineNumber --
function startAnimation(lineNumber) {
Change where that is called to include the number of the line you want
to follow, like startAnimation(0) or startAnimation(1). You'll
probably use a variable there --
var lineToFollow = 0; // assigned however you do this
startAnimation(lineToFollow);
Then when you call the animation on line 2 (say), 2 gets passed into
the function which then follows polys[2].
