I am creating a path intending on an entity patroling it. But the behavior I am seeing is, the entity moves to a point, stops, then randomly turns circles (not always though), hesitates, and then moves toward the next point. It then does it again at the next point, and so on. Here are the points:

Any ideas?

You need to set his destination as the furthest point, and set the look-ahead to be quite short. This will make hiom walk directly to the far point without hesitating, but via the intermediary points.

Here's the tutorial I wrote some time ago about fine tuning AI behaviour...

How exactly do I do what you suggest? I see you just cut and pasted the same line from the documentation. But, that doesn't explain the process. I read the post you mentioned, but did not find an answer. So here is my code, can you tell me what I have left out or perhaps have written wrong? Thanks.

So what happens is the entity moves rather erratically, stops at each point, turns various directions, moves to the next point and does the same thing again.

Disregard, I figured it out.
