  if/then and index to create opposing rotation per layer

  Posted by Brandon Mcfarland on January 24, 2011 at 10:30 pm

  I’m trying to have every other layer start it’s rotation at 90 and -90 and then ease into it’s initial value. The way I have it written now seems to disregard index values and just bases it off of what I enter into the line
  “n=index-90”

  Thanks,
  Brandon

  start =
n=index-90;
i=(index%2)-n;
if (i=1){ n=90 }else{ n=-90};
end = value;

  ease(time, 0, 2 + (index*thisComp.frameDuration), start, end)

  Try this (you might have to switch the -1 and 1):

  startVal = 90*(index%2 ? -1 : 1);
  ease(time,0,2 + index*thisComp.frameDuration,startVal,value)
