Details about setting areas for different area cost.

[johnwon2007]

First of all thank you for providing this amazing library!
while i was using this library i kind of got stuck on setting areas and its cost.

I did see a post about adding velocity weights here #431
but I still have no idea how this works so I was wondering if I could get some help.

From what I understand, I can either:

1. Mark areas when generating the navMesh, or
2. Use a QueryFilter to modify an already generated navMesh.

For the first approach, I’m not sure how to mark areas during navMesh generation.

For the second approach, after creating a navMesh, I think I can use setPolyArea to assign areas to polygons, then use a QueryFilter with setAreaCost for each area, and then just use findPath. Is that correct?

My main questions are:

How do I set an area to be a square or other shape, rather than just a polygon?
How can I mark areas during navMesh generation (approach 1)?
Thank you!
