Adds helper functions to set the links start and end position with global positions or get them as global positions. Adds global start and end position for the navigation link to the 'link_reached' signal of NavigationAgent. That signal gets emitted when a navigation link waypoint is reached. Requires that 'owner' meta data is enabled on the NavigationAgent.

|
|
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.

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

<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.
