Svdl, magnets won't work on a walk path. You can use a walk path to creat a motion with a verticle component, the X-Fighter in post #9 is following a walk path. This works quite well for a rigid prop such as plane or a boat moving over waves where it is only the motion of the BODY actor that is important and where the attitude of the prop is supposed to follow the contour of the path, but there are some problems applying this to a human figure where the attitude should remain verticle.

More info on creating a path with a verticle component is available in the thread linked in post #1.
