hey i'm working in text animation ( after effects cc 2018 )it's arabic/persian ( it's RTL yes )but the animation from template it's comes from left to righthow i can reverse than animation ( RTL Animation )here's screenshots and script in case maybe help

Code :

freq = effect("Frequency")("ADBE Slider Control-0001");

decay = effect("Decay")("ADBE Slider Control-0001");

if(effect("Random Time")("ADBE Checkbox Control-0001")==0){

retard = textIndex*thisComp.frameDuration*effect("Offset")("ADBE Slider Control-0001");

}else{

seedRandom(index*textIndex,timeless=true);

retard = random(0,1);}

t = time - (inPoint + retard);

startVal = [100,100,100];

endVal = [0,0,0];

duration = effect("Duration")("ADBE Slider Control-0001");

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);

}

Correct answer Rick Gerard

can you give me a sample ?
i just changed like that
if i'm correct, sorry for my lack of knowledge

i did this and text is gone :

freq = effect("Frequency")("ADBE Slider Control-0001");

decay = effect("Decay")("ADBE Slider Control-0001");

if(effect("Random Time")("ADBE Checkbox Control-0001")==0){

retard = textTotal-textIndex*thisComp.frameDuration*effect("Offset")("ADBE Slider Control-0001");

}else{

seedRandom(textTotal-textIndex,timeless=true);

retard = random(0,1);}

t = time - (inPoint + retard);

startVal = [100,100,100];

endVal = [0,0,0];

duration = effect("Duration")("ADBE Slider Control-0001");

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);

}


You left out the parentheses. You have to put in the whole arguement.

freq = effect("Frequency")("ADBE Slider Control-0001");

decay = effect("Decay")("ADBE Slider Control-0001");

if(effect("Random Time")("ADBE Checkbox Control-0001")==0){

retard = (textTotal-textIndex)*thisComp.frameDuration*effect("Offset")("ADBE Slider Control-0001");

         }else{

     seedRandom(index*(textTotal-textIndex),timeless=true);

     retard = random(0,1);}

t = time - (inPoint + retard);

startVal = [100,100,100];

endVal = [0,0,0];

duration = effect("Duration")("ADBE Slider Control-0001");

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);

}

You may need to modify the various occurances of textIndex to read (textTotal-textIndex) instead.

    Mylenium has it right. There are two instances of textIndex so it will take you just a couple of seconds to change that to (textTotal-textIndex)

    Text and word count in expressions always moves from left to right. Subtracting the number of characters from the total will reverse the direction.
