Wiggle Y + ease + hold position
Hello!
I’m trying to make a bunch of null layers wiggle regularly in the Y axis and hold their position for about 10 frames before they start wiggling again. I also would like the motion to be smooth, so I guess it would be a good idea to have an “ease in – ease out” motion every time the movement starts and stops.
On top of that, if possible, I would like to smoothly animate the frequency parameter on the wiggle expression through a Slider Control effect.
So far I could only get the wiggle in Y direction expression working:
x = transform.position[0];
y = transform.position[1];
w = wiggle(1, 200);[x, w[1]];
My ultimate goal with this is to have a bunch of points wiggling so I can connect them later on with a beam effect.
Does anybody have a clue on how to write this expression?
Thank you!

I think I would approach this by coming up with an algorithm to manipulate the time (5th) parameter of wiggle(). That makes it relatively easy to manipulate the speed, or to hold on a particular value, then continue on. The details would depend on the details of your design–what causes it to hold, range of speeds, etc. A bit of work, but definitely do-able.

Uhm.. I never really explored the possibilities of the time parameter in the wiggle, but it seems to be a good approach to the problem.
I’ll definitely look into it.Thanks Dan!
