I use to use Game-editor a few years back and they had a great Path tool. All you did was click on the Path tool, let it know what sprite will follow it and then click on two points, one for the beginning and one for the end, you could end up going back and manipulating the line by adding or subtracting points and adjusting how you like...
I would love to see that in this engine.
Here is the link.
