TUTORIAL AFTER EFFECTS: EFFETTO MOLLA 2° TIPO CON SEMPLICE SCRIPT

change the values of "amp" or "freq" or "decay". 

here the script: 

 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 && t < 1){ v = velocityAtTime(key(n).time - thisComp.frameDuration/1); amp = 0.1; freq = 3; decay = 2.0; value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t); }else{ value; }
