I know this question isn't directly blender related, but I hope someone with more experience with the animation nodes addon could point me in the right direction.
For this version I used Animation Nodes with a Spline Falloff, which kind of works. Though you have to use the AnimAll addon so you can animate the spline that is used for the falloff.
This gets really fiddly as you have to animate more and more points that move to the next point.
I'm wondering if there isn't a more elegant solution for this. Something like an "effector/null Object" Moving along the spline affecting the cubes closest to it? I know you can use object falloffs but as they move away from the cubes..they would come up again. I tried some things with this but can't find a way to get it work.
It would be great if someone could point me in the right direction here.
Edit for clarification: The problem that I have is, that I also need to animate multiple cubes at once (as seen below always two in a row) so going with an idea is not really working as the delay makes them move one after another. I'm also going to animate a harvester along the lines which will take longer to take the curve between the rows..so a delay will only work if I speed up this animation.
