A region of the 2D navigation map. 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' 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. 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. Determines if the [NavigationRegion2D] is enabled or disabled. 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. A bitfield determining all layers the region belongs to. These layers can be checked upon when requesting a path with [method NavigationServer2D.map_get_path]. The [NavigationPolygon] resource to use. When pathfinding moves inside this regions navmesh the traveled distances are multiplied with [code]travel_cost[/code] for determining the shortest path.
