// 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

// Loop Animation With Markers - Created by Animoplex: www.animoplex.com
// Repeat a property's keyframed animation, resetting the loop at the start of every layer marker
// Based loosely on Marker Sync Expression: http://www.motionscript.com/design-guide/marker-sync.html

n = 0;
if (marker.numKeys > 0) {
    n = marker.nearestKey(time).index;
    if (marker.key(n).time > time) {
        n--;
    } // get previous marker index

// Loop Expressions

loopOut("cycle", 0) // Repeat from start to finish, default loop mode
loopOut("pingpong", 2) // Loops last three keyframes back and forth
loopOut("offset", 0) // Repeats animation using last keyframe as new start point
loopOut("continue") // Does not loop, but continues onwards with current velocity

// loopOut evaluates from the first keyframe towards the layer outPoint
// loopIn can be substituted to evaluate from layer inPoint towards last keyframe

// Linear Counterbalance

s = thisComp.layer("Control").effect("Slider Control")("Slider");
a = transform.position;
b = thisComp.layer("Null").toWorld([0,0,0]);
linear(s, 0, 100, a, b)

// Adjust a Slider Control (from 0 to 100) to balance between two values (a and b)

// Linear & Ease Expressions

linear(time, outPoint - 2, outPoint, 100, 0)
ease(transform.opacity, 0, 100, 25, 75)

// Linear fade from 100 to 0 for the last 2 seconds of a layer’s duration
// Ease from 25 to 75 as the Opacity input animates from 0 to 100

animoplex

// Value At Time

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

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

animoplex

// Value Expression

value / 2

// Current property value divided by 2

animoplex

// Posterize Time

posterizeTime(12); value

// Interpolates property at 12 fps regardless of composition frame rate

animoplex

// Time Expression

time * 10

// Output increases by 10 every second
