I've asked a few times for a spline based pathing implementation, and there is supoport from the user community but i dont think it's really something thats on Scirra's radar.
It's also requested for Construct 3. maybe some dev will be able to make a plugin. If i knew more on the coding side of things I would have attempted this myself.
Fusion has a very nice one.
The video shows only straight movement but bezier curve movement - back and forth, looping etc are all possible.
Would be great to have something like this in Construct.
Currently as others have said you can make nodes that you can have the sprite move to, once it gets to the sprite let it look for the next sprite and so on.
