Snapshot from animated spline (master point controller)

[jonahhawk]

I posted this on CG Talk hoping to get some feed back. I see some of you geniuses lurking around there from time to time.

I want to create a new spline at every frame from a spline that has both animated transform as well as animated vertices.

I couldn't find a way to detach with copy so I came up with the following.

  global ss = $
  global ssNum = numknots ss -- number of knots in the selected spline
  global ssa = #() -- empty array of knot point positions
  global knotKeys = #() --empty array of the key frames of the animated knots
  global masterTrack = ss[4][8] --grab the master point controller
  global knotKeys = masterTrack.keys -- array of the keys of the controller
  global keyCount = knotKeys.count -- number in the array of the keys of the controller
  global lastKey =(getkeytime mastertrack.controller keycount).frame as integer --get an integer value for the last key for loops
  
  mapped fn getTheKnots = 
  (
  	(for k in 1 to ssNum do
  		(
  			append ssa (getKnotPoint ss 1 k)
  		)
  	)
  )
  
  mapped fn makeNewShape = 
  (
  	for s in 1 to ssNum do
  	(
  	ns = splineShape()
  	addNewSpline ns
  	addKnot ns 1 #Bezier #Curve (ssa[s])
  	close ns 1
  	updateShape ns
  	)
  	
  )
  
  for i in 1 to lastKey do
  (	slidertime = i
  	getTheKnots
  	makeNewShape
  	--ssa =()
  )
