Ok! My racing game scirra.com/arcade/racing-games/lamboracing-4313 uses path finding to move the AI car around the track.
Which acts just like NODES with out writing all the points.
On start of layout
find path sprite 1,
on path found move along path,
On arrive and car is overlapping sprite 1, find path to sprite 2,
on path found move along path,
on arrive and car is overlapping sprite 2, find path to sprite 3,
on path found move along path.
on arrive and car is overlapping sprite 3, find path to sprite 1,
on path found move along path.
which completes the loop and the AI just keeps driving around the track.
