  Multiple if statements

  Posted by Mio Tanaka on December 18, 2012 at 2:25 am

  Hello, I’m a relatively new to expressions. I tried to make an expression which the same animation starts from multiple layer marker switches, wanting it to be repeated over and over again.

  I’ve tried something like below. Now I know ‘||’ stops working after one of its if statements, but I wonder if there’s a way to do this.

  Also I wanted it to be repeated, say, every 3 seconds. Is there a way to do this?

  var keyTime = key(2).time-key(1).time;
var m1 = thisLayer.marker.key(1).time;
var m2 = thisLayer.marker.key(2).time;

  if (time>m1 || time>m2);
linear(time,m1,m1+keyTime,key(1).value,key(2).value)

  This should work for the markers:

  
n = 0;
m = marker;
if (m.numKeys > 0){
n = m.nearestKey(time).index;
if (m.key(n).time > time) n--;
}

  keyTime = key(2).time-key(1).time;
t = (n > 0) ? (time - m.key(n).time) : 0;
linear(t,0,keyTime,key(1).value,key(2).value)


  and this one should repeat every 3 seconds:

  t = time%3;
  keyTime = key(2).time-key(1).time;
  linear(t,0,keyTime,key(1).value,key(2).value)
