	<brief_description>
		Mesh-based navigation and pathfinding node.
	</brief_description>
	<description>
		[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.

	<methods>
		<method name="get_closest_point" qualifiers="const">
			<return type="Vector3" />
			<argument index="0" name="to_point" type="Vector3" />
			<description>
				Returns the navigation point closest to the point given. Points are in local coordinate space.
			</description>
		</method>
		<method name="get_closest_point_normal" qualifiers="const">
			<return type="Vector3" />
			<argument index="0" name="to_point" type="Vector3" />
			<description>
				Returns the surface normal at the navigation point closest to the point given. Useful for rotating a navigation agent according to the navigation mesh it moves on.
			</description>
		</method>
		<method name="get_closest_point_owner" qualifiers="const">
			<return type="RID" />
			<argument index="0" name="to_point" type="Vector3" />
			<description>
				Returns the owner of the [NavigationMesh] which contains the navigation point closest to the point given. This is usually a [NavigationMeshInstance].
			</description>
		</method>
		<method name="get_closest_point_to_segment" qualifiers="const">
			<return type="Vector3" />
			<argument index="0" name="start" type="Vector3" />
			<argument index="1" name="end" type="Vector3" />
			<argument index="2" name="use_collision" type="bool" default="false" />
			<description>
				Returns the navigation point closest to the given line segment. When enabling [code]use_collision[/code], only considers intersection points between segment and navigation meshes. If multiple intersection points are found, the one closest to the segment start point is returned.
			</description>
		</method>
		<method name="get_rid" qualifiers="const">
			<return type="RID" />
			<description>
				Returns the [RID] of the navigation map on the [NavigationServer].
			</description>
		</method>
		<method name="get_simple_path" qualifiers="const">
			<return type="PoolVector3Array" />
			<argument index="0" name="start" type="Vector3" />
			<argument index="1" name="end" type="Vector3" />
			<argument index="2" name="optimize" type="bool" default="true" />
			<description>
				[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.
				Returns the path between two given points. Points are in local coordinate space. If [code]optimize[/code] is [code]true[/code] (the default), the agent properties associated with each [NavigationMesh] (radius, height, etc.) are considered in the path calculation, otherwise they are ignored.
