Letters appearing in Alphabetical Order via Expression

An Expression Selector for the Opacity Animator (with Opacity value = 0%) with this expression:

text.sourceText.value.charCodeAt(textIndex-1)-97+1 <= time ? 0 : 100;

will make letters appear in alphabetical order with the period of 1 second. This will work for the text consisting of lower-case letters only. If you change “97” to “65”, it will do the same for an all-upper-case-letters text.

Hi Oleg, thanks for your reply. I tried the expression in the Animate Opacity Range Selector but am getting the message “property or method named ‘textIndex’ in Class ‘global’ is missing or does not exist. It may have been renamed, moved, deleted, or the name may have been mistyped.” I’ve attached a screenshot of my timeline below:

You should add an Expression Selector and use that expression for it, not Opacity.
