How do you express the word “between” in Expressions?
I’m trying to learn expressions and am trying to write an expression that uses Ease command to control Position and move a layer through 10 seconds and have it move every 2 seconds. I can get through the first 4 seconds but how do I tell AE that if the time is between 4 and 6 I want variable “third” to be executed and if the time is between 6 and 8 I want variable fourth to be executed and so on and so forth. The numbers in the arrays are just random numbers; I’m only trying to learn not actually do anything work realated. This is what I have so far.
var first = ease(time,0,2,[100,100],[600,100]);
var second = ease(time,2,4,[600,100],[100,600]);
var third = ease(time,4,6,[100,600],[20,500]);
var fourth = ease(time,6,8,[20,500],[300,800]);
var fifth = ease(time,8,10,[300,800],[100,100]);
if (time<2) {var movement = first} else {var movement = second};

This is one way:
if (time < 2){ ease(time,0,2,[100,100],[600,100]); }else if (time < 4){ ease(time,2,4,[600,100],[100,600]); }else if (time < 6){ ease(time,4,6,[100,600],[20,500]); }else if (time < 8){ ease(time,6,8,[20,500],[300,800]); }else{ ease(time,8,10,[300,800],[100,100]); } Dan

Thank you so much for the help. This was a real leap forward in my understanding of Expressions. Just one more question please. Why is the end parentheses “}” coming after the semicolon? So far I’ve learned to place parentheses at the end of variables.

It’s not a parentheses, it’s a curly bracket “}”. You use those to enclose groups of statements to be treated as a single block. Not really necessary in this case, because each else clause only has a single statement. I just do it out of habit.
