Expression to revert tex animation

[Gabriel Silva]

Hello people. I need help. I have the following expressions for animating the text:

####Expression 01####

delay = .05;

myDelay = delay*textIndex;

t = (time – inPoint) – myDelay;

if(t >= 0){
freq = 2;

amplitude = 100;

decay = 8.0;

s = amplitude*Math.cos(freq*t*2*Math.PI)/Math.exp(decay*t);

[s,s];

}else{
value
}

####Expression 02####

delay = .05;
myInDelay = delay*textIndex;
myOutDelay = delay*(textTotal -textIndex + 1);
tStart = inPoint + myInDelay;
tStop = outPoint – myOutDelay;
if ((time < tStart) || (time > tStop)){
t = 0;
}else{
if (time < (tStart + tStop)/2){
t = time – tStart;
}else{
t = tStop – time;
}
}
freq =2;
amplitude = 100;
decay = 8.0;
s = amplitude*Math.cos(freq*t*2*Math.PI)/Math.exp(decay*t);
[s,s]

And I would like that instead of animating by reading order he would animate backwards.
Can you help me?

I think if you replace textIndex with:

((textTotal – textIndex)+1)

it should go backwards.
