Transition/ easing into a parented position
I have a square and a circle a small distance apart. I want the square (child) to ease towards the circle (parent), then ease out into the final parented position.
I don’t want to animate the square’s position first, then turn it into a child and parent it.
I would rather turn the square into a child while it’s in the original position, then have the child transition to the parent’s position to be smooth using ease.
The problem is once I parent the square to the circle, it snaps. It’s not smooth. And I don’t have control in the timeline for the time it should become a parent.
Is it possible to ease into a parent’s position? Or transition to a parent’s position without first animating the child’s position before it’s parented?
Does this make sense?

It sounds a little like the challenge I faced when I wanted to create an eclipse with a lens flare appearing at the edges.
But if not, then take a look at the ease() expression.
You’ll need a controlling variable, maybe just a slider, then it’s
ease(MySlider,0,100,squarePosition,ParentPostion)
This will ease the square from it’s starting position to the parent’s position over the slider’s keyframed from 0 to 100. There’d be a lot of fiddling to get it right, but I think that’s what you’re after.

Not entirely clear how you want to automate the easing, is that using a set time, or another slider that controls the influence of the parent ?
Perhaps the script “Faux Parent” can help you, although I’m not sure if it also has keyframe-able parenting like the script “good parents” which in turn doesn’t offer an influence slider.
Search for “parent” on aescripts for more suggestions.
