„Stretching” objects position across the path

[papryg]

Hello, I am familiar with the concept of follow path.

But how do I achieve something like in this video at 51:30?

The character has a body build in with some vector parts, that are following the „body” path. Each of these objects has their own, internal animation. So far so good, but how did they achieve these objects being stretched in position across the path?

For me it seems to be the position of object being somehow calculated by the length of the path, but Im not sure how can I apply it in my own projects.

The same effect is presented at 53:40, where legs of the character also are build by some vector elements and their position depends on the path that they follow (one the path is short, objects are closer together, once the path is longer, the objects begin to have distances between them)


Thanks in advance,
Patryk

This is because an element's position on the path is a percentage of the overall length of the path. So making the path longer means that 25% is now further from 50%. Adding separate layers to a path will do this automatically.
