Interested in creating a delayed blend (in Illustrator) effect with motion

After a little bit of digging, I’ve found https://forums.creativecow.net/docs/forums/post.php?forumid=2&postid=1036368&univpostid=1036368&pview=t very helpful.

This is the code I’m using.
linear(effect("Completion")("Slider"),0,100,effect("Point A")("Layer").transform.position,effect("Point B")("Layer").transform.position)


I’ve decided to make all the shapes in Illustrator (6 triangles in this instance) and I’m now using them to follow the Point A null while the Point B null is still. How would you apply a valueAtTime to delay the triangles to create a ripple delay effect?

I think my method is pretty botched but I’m learning expressions for the first time at least…

I also forgot to mention that all my triangles are on this path with different “Completion” values so that I can create the ripple effect. It’s a bit of a manual task but I was searching for ways to add a slider to how much the shape is affected by a parent in position and ended up on the link above.

I feel like this thread is all me haha.

I’ve figured it out with this:

delay = 1.5; //number of frames to delay
d = delay*thisComp.frameDuration*(index - 1);

linear(effect("Completion")("Slider"),0,100,
effect("Point A")("Layer").transform.position.valueAtTime(time - d),
effect("Point B")("Layer").transform.position)

I’m looking for the same effect.

Where do you put the expression? In the position of the duplicate layers?
Can you share your setup?

Thanks
