You have this:

audioMax = 25;
completionMax = 0;

audioMin = 0;
completionMin = 100;

a= thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
linear(a,audioMin,audioMax,completionMin,completionMax)

As the “a” value changes from “audioMin” and “audioMax”, the value of the Completion will change in a linear interpolation from completionMin to completionMax.

I looked in Google about “calcValue” but I found nothing intersting about.

Is “calcValue” an specific function of JavaScript Expressions or you created it in the expression?

Thanks.

I agree. Dan’s site was good, but now it is much better. I can see with his new examples that expressions really almost eliminate the use of keyframes.

I think it is the best site about expressions ever created!

Thanks, Dan!

Oh, I recommed the two sites I know about expressions:
http://www.motionscript.com – site of master Dan and https://www.jjgifford.com/expressions/index.html

But if ou are talking about variables, that are letters that we use to “capture” a value, here is a short explanation.

You can just add a variable to simplify your expression. An example: I have this in Opacity property:

(75-5*2)/2

To simplify (or maybe not) I could do this:

l = 75;
m = 5*2;
s = l-m;
c = 2;

s/c

We just eliminate the parentheses. In this case the variables difficult a bit, but in some cases they’re amazing. You can give almost any name to them (there are some “illegal” terms, like “value” and “final”). I could have:

LordScales = 75;
Mom = 4*2;
sugar = LordScales – Mom;
coffee = 2;

sugar/coffee

I could not get it so good, but try creating a Null Object (Layer > New > Null Object – we will call it Controller -) with a Slider (Effect > Expression Controls > Slider Control). So copy and paste the following expression in Glow Radius:

freq = 2; //frequency of wiggle
amp = 15; // amplitude of the wiggle
slider = thisComp.layer(“Controller”).effect(“Slider Control”)(“Slider”); // creates a variable to catch the value of the slider
maxRad = 25; // the maximum radius you want the glow to have
minRad = 0.5; // minimum radius
seedRandom (3, true)
w = wiggle (freq, amp); // creates a variable to catch the wiggle value

linear (slider, 0, 100, minRad, maxRad) + w // as the value of “slider” changes from 0 to 100, the Glow Radius will change from mixRad to maxRad value and this value will be add to “w”‘s value

Now the Glow Radius will wiggle but the main value is going to be controlled by the Slider in the Null.
If you prefer a simple expression just try this:

freq = 2; // frequency of wiggle
amp = 25 // amplitude of wiggle
wiggle (freq, amp)

It works like the bigger one, but the main value will we controlled by the Glow Radius itself.

I tested the both here and worked fine.

There is a Preset in Effects and Presets (Window > Effects and Presets) called Separate XYZ (or something like this). With this preset, you can animate separately the positions so you can rove them separately also.

Well, try changing the In and the Out Points to disable your layer. It is one alternative. But if it is not posible, I can’t help because I could connect a Checkbox Control (Effect/Expression Controls/Checkbox control) to the active switch, but I was unable to do the inverse.

Thank you!

Sorry, I forgot the parentheses in 4th line.

D = Math.exp (time);
mult = 1; //multiplier of D
years = 8000000000000;
Math.round(years/(D*mult))

I created another one also (the “transformation” will be faster in the middle and slower in the end):

D = Math.exp (time);
mult = easeIn (time, 5, 10, 1, 400000000); //multiplier of D, will change between 1-400000000 in an Ease In interpolation
as time changes from 5-10
years = 8000000000000;
Math.floor(years/(D*mult))

I could not get waht you want to do really, but try this in Source Text:

D = Math.exp (time);
mult = 1; //multiplier of D
years = 8000000000000;
Math.round(years/D*mult)

It will start at 8000000000000 and it will decrease fastly. If it is not what you want just tell us here. Hope to have helped!
