+		[i]Deprecated.[/i] [Navigation] node and [method get_simple_path] are deprecated and will be removed in a future version. Use [method NavigationServer.map_get_path] instead.
 		Provides navigation and pathfinding within a collection of [NavigationMesh]es. By default, these will be automatically collected from child [NavigationMeshInstance] nodes. In addition to basic pathfinding, this class also assists with aligning navigation agents with the meshes they are navigating on.
