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. Determines if the [NavigationRegion2D] is enabled or disabled. 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.
