	<description>
		Creates a link between two positions that [NavigationServer3D] 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 NavigationServer3D.map_get_path] will ignore this link.

			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 NavigationServer3D.map_set_link_connection_radius].

		<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 NavigationServer3D.map_get_path].

			Starting position of the link.
			This position will search out the nearest polygon in the navigation mesh to attach to.

		<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.
