We use the Path class in order to have a movement guideline. It is the cornerstone, because it relies on GetParam to map an offset point to follow in its internal guideline, and it also uses GetPosition to convert that referential point to a position in the three-dimensional space along the segments.
The path-following algorithm just makes use of the path's functions in order to get a new position, update the target, and apply the Seek behavior.
