How to create a path of nodes?

Hi all.
I am very beginner in unity so please give a simple answer.
I want to create third person sky traversing game.
the player has some constraint such as limitation of far away from the path.
I have Implemented it with many planes with colliders but i want a new way.

please notice to this: The Level Designer want to create the path of gameplay not me.

So thanx.

You could just write an editor script that adds and removes vector3’s from an array. And on GUI, just draw a catmull-rom smoothed line… Or bezier, whatever flavor you prefer.

In fact I think there’s an itween component that essentially does just that… Itweenpath I think it’s called.
