Waypoints/Navgoals (Scripting)

[Vegar01]

I'm kinda new in the scripting game ,and I'm just wondering, what's the actual difference between a waypoint and a nav-goal?

 

I'm working on a pretty basic script which makes a reborn walk in a circle (around a circle-formed brush). I've put one nav-goal on two of the sides of the brush, and one waypoint in every corner of the room (it's a square room with a round brush in the middle). I want the reborn to walk along the waypoints (which is placed in the corners) to get to the nav-goal, but the reborn always takes the shortest way around, and ignores the waypoints. I have connected all the waypoints, and placed the two navgoals inside two of the waypoints. How do I get the reborn to follow the waypoints, without having to set up a navgoal for every point I want the reborn to walk through.

 

Help pleace.
