No worries. The mask part is easy. I would just pre-comp that layer and apply a mask. Basically, I am looking for a script to fill the screen with a specific symbol of random sizes and random appearance times within a specific time range.

“Fill up the screen in 5 seconds with X copies this specific image and vary the scale from 30-70% of actual.”

Hey Dan, just wanted to thank you for being so responsive to everyone on the board. You really have helped me learn many new things.

Thanks

The goal would be to:

1. Set 1 comp “person”
2. Appy Script that
– Randomly populates the entire page (I can apply mask to manipulate where it shows up)
– Randomly sets delay so the appearances stagger.

Sorry I am doing a terrible job at explaining the goal.
Hopefully that helped.

Thanks!

I created the effect manually but figured there had to be a way to script it. This is what I did manually.

Good to know I was on the right track. the second part of your script was one I was playing with but couldn’t get it to produce any animation. I put the expression in the position layer, right?

Thanks for the quick reply!

It basically calculates the velocity (time spent going from one size to the other) to determine the bounce amount.

You might try this. It is for inertial energy “bounce” based on velocity. I use it for a lot of my stuff when an object grows in a scene.

// Inertial Bounce - Created by Animoplex: www.animoplex.com
// Original Version: https://www.graymachine.com/top-5-effects-expressions/
// Modified expression for a smoother bounce effect and easier editing. Use this on any property with two keyframes to get a nice bounce effect that is based on velocity of the value change. Perfect for a scale from 0 to 100 or a speedy rotation that needs some extra life. Adjust amp, freq and decay values to tweak the effect. Amp is intensity, freq is bounces per second, and decay is the speed of decay, slow to fast.

// Variation A

amp = 5.0; freq = 2.0; decay = 4.0;

n = 0;
if (numKeys > 0) {
n = nearestKey(time).index;
if (key(n).time > time) { n--; }
}
if (n == 0) { t = 0; }
else { t = time - key(n).time; }
if (n > 0 && t < 1) {
v = velocityAtTime(key(n).time - thisComp.frameDuration/10);
value + v*(amp/100)*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);
}
else { value; }
