Oh, that fixed it. Weird. I just swapped out the dash with a ‘-‘ and it resolved the issue. Thanks!

Hi Dan,

I just tried using this expression but I keep coming up with an error:

minVal = 15;
maxVal = 21;
freq = 1;
amp = 110;
loopTime = 3;
t = time % loopTime;
w1 = wiggle(freq, 1, 1, 0.5, t)-value;
w2 = wiggle(freq, 1, 1, 0.5, t – loopTime)-value;

“Error: Syntaxerror: Missing ) after argument list”

w = linear(t, 0, loopTime, w1, w2);
(minVal+maxVal)/2 + (maxVal-minVal)*w

I understand the Loop Period & Animation Speed settings but I realized that it only loops the evolution of the noise shader. I have the noise shader moving from Right to left and the loop settings do not take position into account. Ideally there would be a drift on the noise and it would loop. Hope that makes sense.

Just downloaded and loaded Ease and Wizz. What an awesome script!

So now that I’m looking at the code, is there any way to have a slider control change the values of the keyframes?

SliderPoint = thisComp.layer("CONTROLLER").effect("BLACK_BOX_LENGTH")("Slider");

// Ease and Wizz 2.5.2 : outExpo : All keyframes
// Ian Haigh (https://aescripts.com/ease-and-wizz/)
// Last built: 2017-01-09T15:35:09+11:00

function easeandwizz_outExpo(t, b, c, d) {
var OUT_EXPO_CORRECTION = 1.000976;
return (t==d) ? b+c : c * OUT_EXPO_CORRECTION * (-Math.pow(2, -10 * t/(d)) + 1) + b;
}

function easeAndWizz() {
var n = 0;
if (numKeys > 0) {
n = nearestKey(time).index;
if (key(n).time > time) { n-- }
}

try {
var key1 = key(n);
var key2 = key(n+1);
} catch(e) {
return null;
}

// determine how many dimensions the keyframes need
var dim = 1; // It's gotta have at least ONE dimension
try {
key(1)[1];
dim = 2;
key(1)[2];
dim = 3;
} catch(e) {}

t = time - key1.time;
d = key2.time - key1.time;

sX = key1[0];
eX = key2[0] - key1[0];

if (dim >= 2) {
sY = key1[1];
eY = key2[1] - key1[1];

if (dim >= 3) {
sZ = key1[2];
eZ = key2[2] - key1[2];
}
}

if ((time < key1.time) || (time > key2.time)) {
return value;
} else {
val1 = easeandwizz_outExpo(t, sX, eX, d);
switch (dim) {
case 1:
return val1;
break;
case 2:
val2 = easeandwizz_outExpo(t, sY, eY, d);
return [val1, val2];
break;
case 3:
val2 = easeandwizz_outExpo(t, sY, eY, d);
val3 = easeandwizz_outExpo(t, sZ, eZ, d);
return [val1, val2, val3];
break;
default:
return null;
}
}
}

(easeAndWizz() || value);

Thank you Dan!

Would you know where I can read up more on how to implement Penner’s functions in this situation?
