<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.

<methods>
<method name="get_region_rid" qualifiers="const">
<return type="RID" />
<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.
</description>
</method>
<method name="bake_navigation_polygon">
<return type="void" />
<param index="0" name="on_thread" type="bool" default="true" />
<description>
Bakes the [NavigationPolygon]. If [param on_thread] is set to [code]true[/code] (default), the baking is done on a separate thread.
</description>
</method>
<method name="get_navigation_map" qualifiers="const">
<return type="RID" />
<description>
Returns the current navigation map [RID] use by this region.
</description>
</method>
<method name="set_navigation_map">
<return type="void" />
<param index="0" name="navigation_map" type="RID" />
<description>
Sets the [RID] of the navigation map this region should use. By default the region will automatically join the [World2D] default navigation map so this function is only required to override the default map.

<members>
<member name="enabled" type="bool" setter="set_enabled" getter="is_enabled" default="true">
Determines if the [NavigationPolygonInstance] is enabled or disabled.
</member>
<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>
<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>
<member name="navpoly" type="NavigationPolygon" setter="set_navigation_polygon" getter="get_navigation_polygon">
The [NavigationPolygon] resource to use.
</member>
<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.
