An instance of a [NavigationMesh]. An instance of a [NavigationMesh]. It tells the [Navigation] node what can be navigated and what cannot, based on the [NavigationMesh] resource. This should be a child of a [Navigation] node. Bakes the [NavigationMesh]. If [code]on_thread[/code] is set to [code]true[/code] (default), the baking is done on a separate thread. Baking on separate thread is useful because navigation baking is not a cheap operation. When it is completed, it automatically sets the new [NavigationMesh]. Please note that baking on separate thread may be very slow if geometry is parsed from meshes as async access to each mesh involves heavy synchronization. Returns the [RID] of this region on the [NavigationServer]. Combined with [method NavigationServer.map_get_closest_point_owner] can be used to identify the [NavigationMeshInstance] closest to a point on the merged navigation map. Determines if the [NavigationMeshInstance] is enabled or disabled. The [NavigationMesh] resource to use. Notifies when the navigation mesh bake operation is completed. Notifies when the [NavigationMesh] has changed.
