- <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, but they can also be added on the fly with [method navmesh_add]. 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">
- <return type="Vector3">
- </return>
- <argument index="0" name="to_point" type="Vector3">
- </argument>
- <description>
- Returns the navigation point closest to the point given. Points are in local coordinate space.

- <argument index="0" name="to_point" type="Vector3">
- </argument>
- <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.

- <method name="get_closest_point_owner">
- <return type="Object">
- </return>
- <argument index="0" name="to_point" type="Vector3">
- </argument>
- <description>
- Returns the owner of the [NavigationMesh] which contains the navigation point closest to the point given. This is usually a [NavigationMeshInstance]. For meshes added via [method navmesh_add], returns the owner that was given (or [code]null[/code] if the [code]owner[/code] parameter was omitted).

- <argument index="2" name="use_collision" type="bool" default="false">
- </argument>
- <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.

- <argument index="1" name="end" type="Vector3">
- </argument>
- <argument index="2" name="optimize" type="bool" default="true">
- </argument>
- <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.

- <description>
- Adds a [NavigationMesh]. Returns an ID for use with [method navmesh_remove] or [method navmesh_set_transform]. If given, a [Transform2D] is applied to the polygon. The optional [code]owner[/code] is used as return value for [method get_closest_point_owner].

- <method name="navmesh_remove">
- <return type="void">

- <description>
- Removes the [NavigationMesh] with the given ID.

- <description>
- Sets the transform applied to the [NavigationMesh] with the given ID.
