  Speeding up an animation with the help of sliders

  Posted by Samuel Hansen on February 23, 2023 at 5:15 pm

  I basically manually keyframed a simple scale down animation and would like to tie that to a slider, which is supposed to control, how fast the animation scales down. How would I go about that?

  A scale expression like this might work:

  pct = effect("Slider Control")("Slider")/100;
  val = value;
  if (numKeys > 1 && time > key(1).time){
  	d = (time - key(1).time)*pct;
  	val = valueAtTime(key(1).time + d);
  }
  val
