  If, or, & and, Statements

  Posted by Justin Maloney on June 3, 2015 at 6:23 pm

  Hey there, I’m using alot of if/else statements in my comp and I’m trying to optimize my expressions a little.
  Right now I have this on a layers opacity. Basically if one of three check boxes are turned on, the layer doesn’t appear. Here’s what I got right now.

  v =comp(“99 RENAME ME!”).layer(“Torso Styles”).effect(“V Neck Sweater”)(“Checkbox”);
  c =comp(“99 RENAME ME!”).layer(“Torso Styles”).effect(“Crew Neck Sweater”)(“Checkbox”);
  s = comp(“99 RENAME ME!”).layer(“Torso Styles”).effect(“Striped Shirt”)(“Checkbox”);
  o = value;
  if (v==1) o =0;
  else if (c==1) o = 0;
  else if (s==1) o = 0;

  else (o = 100);

  It works fine and all, but is there a way to say “And” or “Or” to condense my expression? I know “Or” uses the pipes “||” and and is “&&” but I can’t make AE happy. Any help?

  You could do it like this:

  L = comp(“99 RENAME ME!”).layer(“Torso Styles”);
  v =L.effect(“V Neck Sweater”)(“Checkbox”).value;
  c =L.effect(“Crew Neck Sweater”)(“Checkbox”).value;
  s =L.effect(“Striped Shirt”)(“Checkbox”).value;
  if (v || c || s) 0 else 100
