  expression combined with ease and wizz

  Posted by Alfred Timotei on February 7, 2015 at 9:58 pm

  Hello, I’m trying to combine the expression bellow with the out expo from ease and wizz script and I don’t succeed. Any idea how to do this to work?

  -l is the length of the in and out transition
  -0.034 is needed because I have 29.97fps, and if I don’t put there the animation won’t finish
  -the out animation is needed to finish 10 frames early than the outPoint
  -the main idea is to replace the easeOut function with the outExpo

  -the in animation is working (not exactly like the ease and wizz, but is ok) but the out animation don’t finish on time (outPoint-0.33), instead is finish at around outPoint+0.6

  -below are all 3 codes: my initial code, ease and wizz, the code I’m trying to build

  \\my code

  l=thisComp.layer("Animation Master").effect("Slider Control")("Slider");
  op = thisLayer.outPoint-0.034;
  if (0==0){
  v1i = value;
  if (effect("Checkbox Control 5")("Checkbox")==1) {v1 = v1i + [-1920,0]} else if (effect("Checkbox Control 6")("Checkbox")==1) {v1 = v1i + [1920,0]} else if (effect("Checkbox Control 7")("Checkbox")==1) {v1 = v1i + [0,-1080]} else if (effect("Checkbox Control 8")("Checkbox")==1) {v1 = v1i + [0,1080]} else v1 = v1i;
  v2 = value;
  v3 = value;
  v4i = value;
  if (effect("Checkbox Control 9")("Checkbox")==1) {v4 = v4i + [-1920,0]} else if (effect("Checkbox Control 10")("Checkbox")==1) {v4 = v4i + [1920,0]} else if (effect("Checkbox Control 11")("Checkbox")==1) {v4 = v4i + [0,-1080]} else if (effect("Checkbox Control 12")("Checkbox")==1) {v4 = v4i + [0,1080]} else v4 = v4i ;

  t1 = thisLayer.inPoint;
  t2 = t1+l;
  t3 = op-l-0.33;
  t4 = op-0.33;

  if (time < t2)
  easeOut(time,t1,t2,v1,v2)
  else if ((time > t3) || (time > op-(t4-t3)))
  easeOut(time,t3,t4,v3,v4)
  else
  value;
  }else
  value
