Random scale up of multiple objects.
OK so I did a search but couldn’t find anything exactly what I was trying to do.
I have a map of a US State that has about 50 or so locations with push pin dots.
I need these push pin location dots to randomly come on over the course of the animation which is about 5 seconds. Scaling up.
Push Pins need to come on fast (like scale up from 0 to 100% within 12 frames or so with ease).
Might need opacity also from 0 to 100 but not sure yet. Definitely scaling up from 0-100%.
Also might need a specific time duration vs the whole animation duration if client wants them to finish before the animation (say finish at 3.5 secs while comp is 5 sec).
Looked for a few expressions but can’t get one to do just this.
So quick scale up for each individual dots, but all 50 need to randomly fade up over the duration of the animation .
Any help is appreciated.

Something like this maybe (for scale):
maxTime = 3.5;
fadeFrames = 12;
fadeDur = framesToTime(fadeFrames);
seedRandom(index,true);
myStart = random(maxTime - fadeDur);
s = easeOut(time,myStart,myStart+fadeDur,0,100);

I think this exactly did what I need. I cannot express how much this helped. If I have any other questions or changes I’ll reply but I think this solves everything!!
The only thing I could possibly think of them coming back with is a random size of the pins (like a small range of say 25% difference in size randomly). Otherwise this works perfectly!

Like this maybe:
maxTime = 3.5;
fadeFrames = 12;
minScale = 75;
maxScale = 100;
fadeDur = framesToTime(fadeFrames);
seedRandom(index,true);
myStart = random(maxTime - fadeDur);
myScale = random(minScale,maxScale)
s = easeOut(time,myStart,myStart+fadeDur,0,myScale);

Yep that worked! Thanks Dan for all the help. It’s always amazing to see how powerful expressions are and how much time can be saved on things like this. Wish they were easier to do for those of us not gifted with math/coding skills.

Thank you, Dan, for this solve!
