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

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

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

.. rst-class:: classref-introduction-group

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

NavigationServer2D is the server that handles navigation maps, regions and agents. It does not handle A\* navigation from :ref:`AStar3D<class_AStar3D>`.

Maps are made up of regions, which are made 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.

Sets the callback :ref:`Callable<class_Callable>` that gets called after each avoidance processing step for the ``agent``. The calculated ``safe_velocity`` will be dispatched with a signal to the object just before the physics calculations.

\ **Note:** Created callbacks are always processed independently of the SceneTree state as long as the agent is on a navigation map and not freed.

.. rst-class:: classref-method

void **agent_set_use_3d_avoidance** **(** :ref:`RID<class_RID>` agent, :ref:`bool<class_bool>` enabled **)**

Sets if the agent uses the 2D avoidance or the 3D avoidance while avoidance is enabled.

If ``true`` the agent calculates avoidance velocities in 3D for the xyz-axis, e.g. for games that take place in air, unterwater or space. The 3D using agent only avoids other 3D avoidance using agent's. The 3D using agent only reacts to radius based avoidance obstacles. The 3D using agent ignores any vertices based obstacles. The 3D using agent only avoids other 3D using agent's.

If ``false`` the agent calculates avoidance velocities in 2D along the xz-axis ignoring the y-axis. The 2D using agent only avoids other 2D avoidance using agent's. The 2D using agent reacts to radius avoidance obstacles. The 2D using agent reacts to vertices based avoidance obstacles. The 2D using agent only avoids other 2D using agent's. 2D using agents will ignore other 2D using agents or obstacles that are below their current position or above their current position including the agents height in 2D avoidance.

----

.. _class_NavigationServer3D_method_map_force_update:

.. rst-class:: classref-method

void **map_force_update** **(** :ref:`RID<class_RID>` map **)**

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 untouched 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.

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

\ *Deprecated.* This function 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 SceneTree for nodes that should contribute to the navigation mesh baking. The 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.

Returns ``true`` if the provided ``point`` in world space is currently owned by the provided navigation ``region``. Owned in this context means that one of the region's navigation mesh polygon faces has a possible position at the closest distance to this point compared to all other navigation meshes from other navigation regions that are also registered on the navigation map of the provided region.

If multiple navigation meshes have positions at equal distance the navigation region whose polygons are processed first wins the ownership. Polygons are processed in the same order that navigation regions were registered on the NavigationServer.
