First of all sorry if I use improper terms or this is in the wrong thread.

How would I go about making an object (specifically a prefab of a car/clip) move along a path. I assume it would require script_struct's and a script that tells it to move from point a to point b, and so on. I want it to be on a rectangular path going, point a to be, rotate 90°, and then b to c, 90°, c to d 90° and finally d to a.

Any help or ideas would be appreciated, and sorry for how poorly this was written. I have no idea what I'm talking about. I'd be happy to explain more if it helps.
