|
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.
|
|
[b]Note:[/b] The current navigation system has many known issues and will not always return optimal paths as expected. These issues will be fixed in Godot 4.0.

|
|
<description>
|
|
Returns the navigation point closest to the point given. Points are in local coordinate space.

<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.

<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]. 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" />
|
|
<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="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.
|
|
[b]Note:[/b] This method has known issues and will often return non-optimal paths. These issues will be fixed in Godot 4.0.

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].
