This method can be used to rotate a navigation mesh. You can make characters that walk on the ceiling, or handle navigation in a space simulation that has no uniform "up" direction.
Parameter | Description |
---|---|
rotation (pitch, yaw, roll) | navigation mesh rotation |
This example tilts the scene and the navigation mesh by 45 degrees. Note that the navigation agent is aligned to the navmesh rotation.
