	<description>
		Creates a link between two positions that [NavigationServer2D] can route agents through.  Links can be used to express navigation methods that aren't just traveling along the surface of the navigation mesh, like zip-lines, teleporters, or jumping across gaps.

		<member name="bidirectional" type="bool" setter="set_bidirectional" getter="is_bidirectional" default="true">
			Whether this link can be traveled in both directions or only from [member start_position] to [member end_position].
		</member>
		<member name="enabled" type="bool" setter="set_enabled" getter="is_enabled" default="true">
			Whether this link is currently active. If [code]false[/code], [method NavigationServer2D.map_get_path] will ignore this link.

		<member name="end_position" type="Vector2" setter="set_end_position" getter="get_end_position" default="Vector2(0, 0)">
			Ending position of the link.
			This position will search out the nearest polygon in the navigation mesh to attach to.
			The distance the link will search is controlled by [method NavigationServer2D.map_set_link_connection_radius].
		</member>
		<member name="enter_cost" type="float" setter="set_enter_cost" getter="get_enter_cost" default="0.0">
			When pathfinding enters this link from another regions navigation mesh 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 layers the link belongs to. These navigation layers will be checked when requesting a path with [method NavigationServer2D.map_get_path].
		</member>

			Starting position of the link.
			This position will search out the nearest polygon in the navigation mesh to attach to.
			The distance the link will search is controlled by [method NavigationServer2D.map_set_link_connection_radius].
		</member>
		<member name="travel_cost" type="float" setter="set_travel_cost" getter="get_travel_cost" default="1.0">
			When pathfinding moves along the link the traveled distance is multiplied with [code]travel_cost[/code] for determining the shortest path.
