Thank!!
I think i got it!
tc = effect(“Time per character (frame)”)(“Slider”); // time per character (frame)
nc = text.sourceText.length; //nb de caracteres
ad = tc*nc; // animation duration (frame)
i = inPoint*30; // debut animation (frame)
tp = time*30 ; // temp present en frame
(tp-i)*(100/ad)+effect(“Adjust time (frame)”)(“Slider”);
Someone can maybe update it? Sorry for the french comments…
