// Play / Pause Realtime Countdown - Created by Animoplex: www.animoplex.com
// Counts down a clock in realtime with the ability to play and pause the countdown with a checkbox
// NOTE: Expression will gradually slow down over duration of comp due to the while loop mechanic

src = effect("Checkbox Control")("Checkbox"); // play/pause control
dur = thisComp.frameDuration; // length of 1 frame
count = 300; // 5 minutes in seconds
t = 0;

function addZero(n) { // adds a zero to the end of numbers 0-9

// Value At Time

thisComp.layer(index - 1).transform.scale.valueAtTime(time - 2)

// Output Scale of layer above, delayed in time by 2 seconds
