Checkbox Controlled Opacity

[Dan Ebberts]

Try it like this:

thisComp.layer("Adjustment Layer 4").effect("Checkbox Control")("Checkbox")==1 ? value else 0

Thanks dan!

Made it work with this:
if(thisComp.layer(“Adjustment Layer 4”).effect(“Checkbox Control”)(“Checkbox”)==1) value else 0

Okay. What if I want to go more advanced.

So “on” only uses the 2 first keyframes and “off” only use the 2 last ones?

A single-line if/else like that will only work with the Legacy ExtendScript engine (or an old version of AE).

Try this:

cb = thisComp.layer("Adjustment Layer 4").effect("Checkbox Control")("Checkbox");
if (numKeys > 3){
  if (cb.numKeys > 0){
    n = cb.nearestKey(time).index;
    if (time < cb.key(n).time) n--;
    if (n > 0){
      t = time - cb.key(n).time;
      if (cb.value){
        t1 = key(1).time;
        t2 = key(2).time;
      }else{
        t1 = key(3).time;
        t2 = key(4).time;
      }
      tt = linear(t,0,t2-t1,t1,t2);
    }else{
      tt =  (cb.value) ? key(1).time : key(3).time;
    }
  }else{
    tt =  (cb.value) ? key(1).time : key(3).time;
  }
  valueAtTime(tt);
}else{
  cb.value ? value : 0;
}
