	<description>
		A link between two positions on [NavigationRegion3D]s that agents can be routed through. These positions can be on the same [NavigationRegion3D] or on two different ones. Links are useful to express navigation methods other than traveling along the surface of the navigation mesh, such as ziplines, teleporters, or gaps that can be jumped across.

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

			When pathfinding enters this link from another regions navigation mesh the [member enter_cost] value is added to the path distance for determining the shortest path.

		<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 [member travel_cost] for determining the shortest path.
