  marker triggers leader animation

  Posted by Peter Zeet on August 12, 2013 at 7:27 pm

  so…
  I have a “leader” null with an animated slider on it
  And other layers which I would like to mimic that slider keyframes when timeline reach a marker..
  I tried to mess a bit with the markers but obviously it doesn’t work (the slider controls their A to B position):
  It should go on each layer’s position:
  
slider = thisComp.layer("lead").effect("go")("Slider");
init=effect("init")("3D Point");
end=effect("end")("3D Point");

  n = 0;
  if (marker.numKeys > 0){
  n = marker.nearestKey(time).index;
  if (marker.key(n).time > time) n--;
  }
  if (n == 0){
  value;
  } else {
  t = time - marker.key(n).time;
  a=linear(t*slider,0,100,init,end);
  a

  }

  The animation goes from the marker, but doesn’t mimic the leader keyframes or animation curves…

  Any advice is welcome!
