Reverse this expression on Type

[KDJ_Motion]

I folowed this ( https://www.youtube.com/watch?v=LRazU7uNgD0 ) tutorial which allowed me to get a really nice bouncy text animation using this expression:

freq = 1;
decay = 7;
duration = 0.10;
retard = textIndex*thisComp.frameDuration*2;
t = time - (inPoint + retard);
startVal = [100,100,100];endVal = [0,0,0];
if (t < duration){
linear(t,0,duration,startVal,endVal);
}else{
amp = (endVal - startVal)/duration;
w = freq*Math.PI*2;
endVal + amp*(Math.sin((t-duration)*w)/Math.exp(decay*(t-duration))/w);}

I wondered if it's possible to start the animation from the end of the text and not the start and speed up the animation.

I have attached an example below - I want the bottom line to start from the 'g' and go in just like the top line starts from the 'a' and goes in. 

Appreciate any input.

Simply revert the text animator or change the t variable to reference the end time by ways of outPoint-retard or something like that. Speeding up the animation simply depends on the parameters defined at the beginning for decay, frequency and duration (per character). Simply play around with them.

To get it to go backwards, I think you just need to change this line:

retard = textIndex*thisComp.frameDuration*2;

to this:

retard = (textTotal-textIndex)*thisComp.frameDuration*2;

That worked great.

Thank you.
