2D navigation and pathfinding node.

Navigation2D provides navigation and pathfinding within a 2D area, specified as a collection of [NavigationPolygon] resources. By default, these are automatically collected from child [NavigationPolygonInstance] nodes, but they can also be added on the fly with [method navpoly_add].
|
|
[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.

Returns the navigation point closest to the point given. Points are in local coordinate space.

|
Returns the owner of the [NavigationPolygon] which contains the navigation point closest to the point given. This is usually a [NavigationPolygonInstance]. For polygons added via [method navpoly_add], returns the owner that was given (or [code]null[/code] if the [code]owner[/code] parameter was omitted).

Returns the path between two given points. Points are in local coordinate space. If [code]optimize[/code] is [code]true[/code] (the default), the path is smoothed by merging path segments where possible.
|
|
[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 [NavigationPolygon]. Returns an ID for use with [method navpoly_remove] or [method navpoly_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].
