Follow the current OffMeshLink.

When the autoTraverseOffMeshLink property is switched off an agent will pause at an off-mesh link until this function is called to let it pass. This can be used to allow characters access selectively (eg, to simulate openable doors or obstacles that only certain characters can pass, etc).

	private var agent: NavMeshAgent;
	function Start () {
		agent = GetComponent.<NavMeshAgent>();
	}
	
	// Let an agent cross the off-mesh link if he has
	// the right door key.
	function CheckForDoorKey(doorKeys: Hashtable) {
		if (agent.isOnOffMeshLink) {
			if (doorKeys.ContainsKey(agent.currentOffMeshLinkData.offMeshLink.name)) {
				agent.CompleteOffMeshLink();
			}	
		}
	}
