Description

|
|
-----------
|
||
|
|
|
||
|
|
*Deprecated.* **Navigation2D** node and :ref:`get_simple_path<class_Navigation2D_method_get_simple_path>` are deprecated and will be removed in a future version. Use :ref:`Navigation2DServer.map_get_path<class_Navigation2DServer_method_map_get_path>` instead.
|
||
|
|
|
||
|
|
Navigation2D provides navigation and pathfinding within a 2D area, specified as a collection of :ref:`NavigationPolygon<class_NavigationPolygon>` resources. By default, these are automatically collected from child :ref:`NavigationPolygonInstance<class_NavigationPolygonInstance>` nodes.
