A region of the 2D navigation map.
|
|
</brief_description>
|
|
<description>
|
|
A region of the navigation map. It tells the [NavigationServer2D] what can be navigated and what cannot, based on its [NavigationPolygon] resource.
|
|
Two regions can be connected to each other if they share a similar edge. You can set the minimum distance between two vertices required to connect two edges by using [method NavigationServer2D.map_set_edge_connection_margin].
|
|
[b]Note:[/b] Overlapping two regions' navigation polygons is not enough for connecting two regions. They must share a similar edge.
|
|
The pathfinding cost of entering this region from another region can be controlled with the [member enter_cost] value.
|
|
[b]Note:[/b] This value is not added to the path cost when the start position is already inside this region.
|
|
The pathfinding cost of traveling distances inside this region can be controlled with the [member travel_cost] multiplier.
|
|
[b]Note:[/b] This node caches changes to its properties, so if you make changes to the underlying region [RID] in [NavigationServer2D], they will not be reflected in this node's properties.

<description>
|
|
Returns the [RID] of this region on the [NavigationServer2D]. Combined with [method NavigationServer2D.map_get_closest_point_owner] can be used to identify the [NavigationRegion2D] closest to a point on the merged navigation map.

When pathfinding enters this region's navigation mesh from another regions navigation mesh the [code]enter_cost[/code] value is added to the path distance for determining the shortest path.

<member name="navigation_layers" type="int" setter="set_navigation_layers" getter="get_navigation_layers" default="1">
|
|
A bitfield determining all navigation layers the region belongs to. These navigation layers can be checked upon when requesting a path with [method NavigationServer2D.map_get_path].

The [NavigationPolygon] resource to use.

<member name="travel_cost" type="float" setter="set_travel_cost" getter="get_travel_cost" default="1.0">
|
|
When pathfinding moves inside this region's navigation mesh the traveled distances are multiplied with [code]travel_cost[/code] for determining the shortest path.
