Any examples to build the NavMesh on my own and only use Detour lib separately?

[lhhts...@gmail.com]

Hi, 

I have some very specific requirements for my nav mesh. And it is mainly 2D with lots of other requirements, e.g. area cost, area shape, etc. I'd like to build the nav mesh data manually and verify it on my own. Then only use Detour purely for the FindPath function.

Is this easy? Any examples about that? What kind of API and data structure I should use?

For example, I was looking for something like:

dtNavMesh nav_mesh;

nav_mesh.init(...)

...

// add my custom polygons one by one

nav_mesh.addPolygon(poly_data);

// set polygon neighbors

nav_mesh.setNeighbor(poly, neighboring_ploys);

// set polygon area cost

nav_mesh.setArea(poly, area);

// then some post processing for the nav_mesh to prepare for path finding;

nav_mesh.doSomething();

// then I can directly query path finding using Detour lib.

dtNavMeshQuery.findPath(...)
