Random population people icons on map
What I am looking for is a script that will enable 50-100 people icons pop up on a map. Would love to be able to have them at random scales between two values. I know there are lots of posts about random placements, but I cannot find one that particularly fits my case and I am a script idiot so I am reaching out.
Right now I just have a pre-comp with an icon in it that just scales in. Basically pops up/appears.
This voiceover might better help give you a mental picture of what I am going for.
“The population of Nebraska has grown from 2million to 20 million in the past 5 years”
The people just seed in random areas at random scales.
Thanks for the help in advance.

These might get you started:
// scale
minScale = 50;
maxScale = 150;
rampTime = .25;
seedRandom(index,true);
s = random(minScale,maxScale);
ease(time,inPoint,inPoint+rampTime,[0,0],[s,s])// position
minX = 0;
maxX = thisComp.width;
minY = 0;
maxY = thisComp.height;
seedRandom(index,true);
random([minX,minY],[maxX,maxY]);Dan

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!

Yes, it’s a Position expression. What kind of animation are you looking for?

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

I don’t see any position animation, but it looks like the scale expression needs a random delay:
// scale
minScale = 50;
maxScale = 150;
maxDelay = 1;
rampTime = .25;
seedRandom(index,true);
s = random(minScale,maxScale);
d = random(maxDelay);
ease(time,inPoint+d,inPoint+d+rampTime,[0,0],[s,s])Dan

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!

Ah, sorry. I thought you were looking for expressions. That’s a little trickier, especially the masked area part. Certainly not something I can just post off the top of my head.

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

It sounds very straightforward. Hopefully someone has time to crank it out for you.
