  combining multiple if else statements

  Posted by Adam Greenberg on April 26, 2023 at 1:55 pm

  Hi all, I thought I saw this posted here, and I searched I cannot find it, but is there a way to rewrite this expression in a better way ( but not using an index method just in case the order of things gets changed ) .

  I thought a ternary operator would maybe save some lines if i set some variables first.

  there are 6 layers in a composition and i want the position in a different composition to change based on which precomp the user has turned on.

  thanks so much

  if(comp(“EDIT”).layer(“1”).active) -133.2; else

  if(comp(“EDIT”).layer(“2”).active) -57.2; else

  if(comp(“EDIT”).layer(“3”).active) -15.2; else

  if(comp(“EDIT”).layer(“4”).active) 61.2; else

  if(comp(“EDIT”).layer(“5”).active) 61.2; else

  179.2

  I might do it like this, but it doesn’t really save much unless you added more layers:

  L = [  "1",    "2",    "3",  "4",  "5"];
  V = [-133.2, -57.2 , -15.2, 61.2, 61.2];
  val = 179.2;
  for (i = 0; i < L.length; i++){
    if (comp("EDIT").layer(L[i]).active){
      val = V[i];
      break;
    }
  }
  val
