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

<member name="up_vector" type="Vector3" setter="set_up_vector" getter="get_up_vector" default="Vector3( 0, 1, 0 )">
Defines which direction is up. By default, this is [code](0, 1, 0)[/code], which is the world's "up" direction.
</member>

<signal name="map_changed">
<argument index="0" name="map" type="RID" />
<description>
Emitted when a navigation map is updated, when a region moves or is modified.
