<brief_description>
|
|
A region of the 2D navigation map.
|
|
</brief_description>
|
|
<description>
|
|
A region of the navigation map. It tells the [Navigation2DServer] what can be navigated and what cannot, based on its [NavigationPolygon] resource.
|
|
By default this node will register to the default [World2D] navigation map. If this node is a child of a [Navigation2D] node it will register to the navigation map of the navigation node.
|
|
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 Navigation2DServer.map_set_edge_connection_margin].
|
|
[b]Note:[/b] Overlapping two regions' 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.

<description>
|
|
Returns the [RID] of this region on the [Navigation2DServer]. Combined with [method Navigation2DServer.map_get_closest_point_owner] can be used to identify the [NavigationPolygonInstance] closest to a point on the merged navigation map.

<member name="enabled" type="bool" setter="set_enabled" getter="is_enabled" default="true">

Determines if the [NavigationPolygonInstance] is enabled or disabled.

<member name="enter_cost" type="float" setter="set_enter_cost" getter="get_enter_cost" default="0.0">
|
|
When pathfinding enters this regions navmesh from another regions navmesh 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 map layers the [NavigationPolygon] belongs to. On path requests with [method Navigation2DServer.map_get_path] navmeshes without matching layers will be ignored and the navigation map will only proximity merge different navmeshes with matching layers.

<member name="navpoly" type="NavigationPolygon" setter="set_navigation_polygon" getter="get_navigation_polygon">
|
|
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 regions navmesh the traveled distances are multiplied with [code]travel_cost[/code] for determining the shortest path.
