Timer time.toFixed(1) linked to a checkbox control effect.
I’m trying to make a timer count up with the expression “time.toFixed(1)”, and I linked it to a Checkbox Control Effect, so that when the checkbox is On, the timer runs, and when it’s Off, the timer freezes at that frame.
I wanna make it as automated as possible, so I could just put On/Off keyframes and the timer is animated according to the keyframes.
I tried this expression:if(thisComp.layer("Control 1").effect("Control")("Checkbox")>0){time.toFixed(1)} else {}But I don’t know what expression I should use in the else {} statement.
I don’t wanna use a Slider Control, because the video i’m making requires that the timer has to go exactly at the actual time, not faster/slower. And it’s so hard to get that on point with the slider.Any recommendations? I would really apreciate it

Try this:
p = thisComp.layer("Control 1").effect("Control")("Checkbox");
t = p.value ? time : 0;
if (p.numKeys > 0){
n = p.nearestKey(time).index;
if (p.key(n).time > time) n--;
if (n > 0){
t = p.key(1).value ? p.key(1).time : 0;
t += p.value ? time - p.key(n).time : 0;
for (i = 2; i <= n; i++){
t += p.key(i-1).value ? p.key(i).time - p.key(i-1).time : 0;
}
}
}
t.toFixed(1)
