  Switch Case in text layer returns the switch the value, Having to use switch(true)

  Posted by Frederic Antoinette on August 28, 2018 at 7:33 am

  Created a pseudo effect for a template, with a popup.
  And depending on the what is on the popup the sentence should change.
  here is the code
  sel = thisComp.layer("Control").effect("Carry Forward")("First Message");
switch(sel){
case 1:
"CARRY FORWARD PICK 6" ;
break;

  case 2:
  "CARRY FORWARD PICK 8";
  break;

  case 3:
"CARRY FORWARD PICK 4";
break;
}

  However though it doesn’t give me any error it ends up with the text displaying the “sel” value.
  That is “1”, “2”, or “3” instead of the sentence.

  I also tried to put
  value = “….” in the cases
  same results

  Searching the web I saw something about a switch using “true” instead of a variable, this one worked:

  sel = thisComp.layer("Control").effect("Carry Forward")("First Message");
switch(true){
case (sel ==1):
"CARRY FORWARD PICK 6" ;
break;

  case (sel == 2):
  "CARRY FORWARD PICK 8";
  break;

  case (sel == 3):
"CARRY FORWARD PICK 4";
break;
}

  Any idea why the first one didn’t work, shouldn’t it have the same results?

  I tried it with a slider control and it didn’t worked out until I rounded the number.

  Maybe this will help your problem too.

  sel = Math.floor(thisComp.layer("Control").effect("Carry Forward")("First Message"));
switch(sel){
case 1:
"CARRY FORWARD PICK 6" ;
break;

  case 2:
  "CARRY FORWARD PICK 8";
  break;

  case 3:
"CARRY FORWARD PICK 4";
break;
}

  Good catch.
  It worked
  I would have done that if I was using a slider, but I though with a pseudo popup it wouldn’t be needed.
  So I guess I will call it a little bug that the value of these pseudo popup effects are not exact integers and we need to round it.

  Thanks
