<brief_description>
A collection of [code]NavigationMesh[/code] resources and methods used for pathfinding.
Mesh-based navigation and pathfinding node.
</brief_description>
<description>
The Navigation node is used for basic or advanced navigation. By default it will automatically collect all child [code]NavigationMesh[/code] resources, but they can also be added on the fly through scripting. It can be used for generating a simple path between two points or it can be used to ensure that a navigation agent is angled perfectly to the terrain it is navigating.
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.

Returns the surface normal of the navigation mesh at the point passed. For instance, if the point passed was at a 45 degree slope it would return something like (0.5,0.5,0). This is useful for rotating a navigation agent in accordance with the [code]NavigationMesh[/code].

Returns the nearest [code]NavigationMeshInstance[/code] to the point passed.
Returns the owner of the [NavigationMesh] which contains the navigation point closest to the point given. This is usually a [NavigtionMeshInstance]. 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).

Returns the nearest point to the line segment passed. The third optional parameter takes collisions into account.
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.

Returns a path of points as a [code]PoolVector3Array[/code]. If [code]optimize[/code] is false the [code]NavigationMesh[/code] agent properties will be taken into account, otherwise it will return the nearest path and ignore agent radius, height, etc.
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] (raidus, height, etc.) are considered in the path calculation, otherwise they are ignored.
