第一个表达式：
delay = .05;
myDelay = delay*textIndex;
t = (time - inPoint) - myDelay;
if (t >= 0){
freq =2;
amplitude = 80;
decay = 8.0;
s = amplitude*Math.cos(freq*t*2*Math.PI)/Math.exp(decay*t);
[s,s]
}else{
value
}
第二个表达式：
delay = .05
;
myDelay = delay*textIndex;
t = (time - inPoint) - myDelay;
if (t >= 0){
freq =1;
amplitude = 200;
decay = 5.0;
s = amplitude*Math.cos(freq*t*2*Math.PI)/Math.exp(decay*t);
[s,s]
}else{
value
}
第三个表达式：
delay = .025;
myDelay = delay*textIndex;
t = (time - inPoint) - myDelay;
if (t >= 0){
freq =2;
amplitude = 80;
decay = 8.0;
s = amplitude*Math.cos(freq*t*2*Math.PI)/Math.exp(decay*t);
[s,s]
}else{
value
}
