  How to Combine 2 Expressions? Inerta Positon with Loop

  Posted by João Queirós on April 19, 2013 at 11:54 pm

  Hello guys,

  Can i join this two expressions?

  1 – INERTA POSITION
  ————————————————-

  1 LOOP

  I want to loop the inerta position expression added to position. Hope you could help me!

  Thanks,
  JoãoQueirós

  1 - INERTA POSITION

  n = 0;
  if (numKeys > 0)
  {n = nearestKey(time).index;if (key(n).time > time){n--;}}
  if (n == 0) {t = 0;} else {t = time - key(n).time;}

  if (n > 0){v = velocityAtTime(key(n).time - thisComp.frameDuration/10);
  amp = 3;
  freq = 2.0;
  decay = 3.0;

  value + (v/100)*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);}else

  {value;}

  1 LOOP
loopOut(type = "cycle", numKeyframes = 0)

  Maybe put one expression on a slider, and add it to the result of the other.

  It´s a solution Mitch! But i didn´t make it, i´m a little new with expressions:

  Here´s my test file, i put the slider on the shape object, and insert the loop expression on it, but gives an error: https://www.mediafire.com/file/ulsvtb38e49apeb/teste_to_combine_expressions.aep

  Thanks for the response
