Object doesn't follow the navigation mesh path using steering actuator So, I manually created a navigation mesh (i.e. added and edited a plane mesh > changed the physics type in bge to navigation mesh). I then added a steering actuator (path following) to my human model, set-up the target object and used the navigation mesh I just created. But when I press P, the human model doesn't follow the path of the navigation mesh. What it does is walk through a path that doesn't have a navigation mesh.



What I want is to make the actor object (human model) to use the navigation mesh as the path like so,


This is my logic set-up


Also, the human model can't detect any obstacles along the way, but the is another problem.

Any help is appreciated. Thanks in advance.

Building the navigation mesh using the properties in the Scene also doesn't work
Instead of setting a "Navigation Mesh" physics type on an existing object, you should generate the navigation mesh via the relevant button in the scene properties.

In my tests, that seems to work fine.

Here's a tutorial for that procedure: https://www.youtube.com/watch?v=aMWeTXL98mM

And here's a working demo: nav_mesh.blend
