Works great, waiting for dynamic obstacles =]

That's what i mean. Doesn't esenthel already have dynamic obstacles though? It would be great if the blocks you place were dynamic obstacles. But it seems like that wpuld require alot of processing

Thanks ill check it out, at work at the moment

I don't feel rebuilding the path database each time an entity is moving, so I guess it is better to implementing it from scratch to get more freedom.

pathBuild works for 2D path,
for navmeshes you should use PathObstacle (check Game::Door sources)
everytime pathobstacle needs to be modified/changed the path meshes of Game::Area need to be rebuilded (this is how recast works)

Oooh...aaah...

That's all I have to say on this!

Recast also allows for updating the poly flags status as 'blocked' and 'non-blocked' I don't think this functionality has been removed from Recast, and with the way the Game::Chr searches paths I'd think allowing to point to the poly flags instead of rebuilding the navmesh completely is alot faster.

Can I put the create/del calls to PathObstacle() in a separate thread? I'm thinking of multi-threading the calls.

please don't, this will not improve performance.
setting obstacles in background thread is on the roadmap

Should be possible to set flag status, better then rebuilding the navmesh. Feature like recast navigation + avoid closest neighbors can be useful.

Edit:

Like Zervox pointed out :]

but recast generates polys in "random" way, they are not organized for your purpose, setting flags, would first require, that polys are set the way you expect them
blocking flags will be available in the future

Here is maybe some useful info, (project made in ogre)

How to make this pathfinding working with water? Character can't go through the water even if the depth of the water is 0.

check the 'walkable_flags' for path find
