NavigationServer3D
==================

**Experimental:** This class may be changed or removed in future versions.

**Inherits:** :ref:`Object<class_Object>`

A server interface for low-level 3D navigation access.

Description
-----------

NavigationServer3D is the server that handles navigation maps, regions and agents. It does not handle A\* navigation from :ref:`AStar3D<class_AStar3D>`.

Maps are divided into regions, which are composed of navigation meshes. Together, they define the navigable areas in the 3D world.

\ **Note:** Most **NavigationServer3D** changes take effect after the next physics frame and not immediately. This includes all changes made to maps, regions or agents by navigation-related nodes in the scene tree or made through scripts.

For two regions to be connected to each other, they must share a similar edge. An edge is considered connected to another if both of its two vertices are at a distance less than ``edge_connection_margin`` to the respective other edge's vertex.

You may assign navigation layers to regions with :ref:`region_set_navigation_layers()<class_NavigationServer3D_method_region_set_navigation_layers>`, which then can be checked upon when requesting a path with :ref:`map_get_path()<class_NavigationServer3D_method_map_get_path>`. This can be used to allow or deny certain areas for some objects.

To use the collision avoidance system, you may use agents. You can set an agent's target velocity, then the servers will emit a callback with a modified velocity.

\ **Note:** The collision avoidance system ignores regions. Using the modified velocity directly may move an agent outside of the traversable area. This is a limitation of the collision avoidance system, any more complex situation may require the use of the physics engine.

This server keeps tracks of any call and executes them during the sync phase. This means that you can request any change to the map, using any thread, without worrying.

|void| **map_force_update**\ (\ map\: :ref:`RID<class_RID>`\ ) :ref:`🔗<class_NavigationServer3D_method_map_force_update>`

**Deprecated:** This method is no longer supported, as it is incompatible with asynchronous updates. It can only be used in a single-threaded context, at your own risk.

This function immediately forces synchronization of the specified navigation ``map`` :ref:`RID<class_RID>`. By default navigation maps are only synchronized at the end of each physics frame. This function can be used to immediately (re)calculate all the navigation meshes and region connections of the navigation map. This makes it possible to query a navigation path for a changed map immediately and in the same frame (multiple times if needed).

Due to technical restrictions the current NavigationServer command queue will be flushed. This means all already queued update commands for this physics frame will be executed, even those intended for other maps, regions and agents not part of the specified map. The expensive computation of the navigation meshes and region connections of a map will only be done for the specified map. Other maps will receive the normal synchronization at the end of the physics frame. Should the specified map receive changes after the forced update it will update again as well when the other maps receive their update.

Avoidance processing and dispatch of the ``safe_velocity`` signals is unaffected by this function and continues to happen for all maps and agents at the end of the physics frame.

\ **Note:** With great power comes great responsibility. This function should only be used by users that really know what they are doing and have a good reason for it. Forcing an immediate update of a navigation map requires locking the NavigationServer and flushing the entire NavigationServer command queue. Not only can this severely impact the performance of a game but it can also introduce bugs if used inappropriately without much foresight.

Parses the :ref:`SceneTree<class_SceneTree>` for source geometry according to the properties of ``navigation_mesh``. Updates the provided ``source_geometry_data`` resource with the resulting data. The resource can then be used to bake a navigation mesh with :ref:`bake_from_source_geometry_data()<class_NavigationServer3D_method_bake_from_source_geometry_data>`. After the process is finished the optional ``callback`` will be called.

\ **Note:** This function needs to run on the main thread or with a deferred call as the SceneTree is not thread-safe.

\ **Performance:** While convenient, reading data arrays from :ref:`Mesh<class_Mesh>` resources can affect the frame rate negatively. The data needs to be received from the GPU, stalling the :ref:`RenderingServer<class_RenderingServer>` in the process. For performance prefer the use of e.g. collision shapes or creating the data arrays entirely in code.

**Deprecated:** This method is deprecated due to core threading changes. To upgrade existing code, first create a :ref:`NavigationMeshSourceGeometryData3D<class_NavigationMeshSourceGeometryData3D>` resource. Use this resource with :ref:`parse_source_geometry_data()<class_NavigationServer3D_method_parse_source_geometry_data>` to parse the :ref:`SceneTree<class_SceneTree>` for nodes that should contribute to the navigation mesh baking. The :ref:`SceneTree<class_SceneTree>` parsing needs to happen on the main thread. After the parsing is finished use the resource with :ref:`bake_from_source_geometry_data()<class_NavigationServer3D_method_bake_from_source_geometry_data>` to bake a navigation mesh.

Bakes the ``navigation_mesh`` with bake source geometry collected starting from the ``root_node``.
