A* Pathfinding Error when I try to give it a new path?

Questions & Answers

I fixed this problem, but use this as reference. I have added comments to where I changed the script.

using UnityEngine;
using System.Collections;
using Pathfinding;

public class AIPather : MonoBehaviour {

	Seeker seeker;
	Path path;
	int currentWaypoint;

	float speed = 20f;

	CharacterController characterController;

	float maxWaypointDistance = 2f;

	public Vector3 target;

	public GameObject moveMarker;

	// Use this for initialization
	void Start () {
		seeker = GetComponent<Seeker>();
		seeker.StartPath(transform.position, target, OnPathComplete);
		characterController = GetComponent<CharacterController>();
	}

	public void OnPathComplete(Path p){
		if (!p.error) {
			path = p;
			currentWaypoint = 0;
		}
		else {
			Debug.LogError (p.error);
		}
	}

	void FixedUpdate() {
		if(Input.GetMouseButtonDown(1)) {
			Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
			RaycastHit hitInfo;
			
			if (Physics.Raycast(ray, out hitInfo)) {
				Vector3 hitPoint = hitInfo.point;
				//Instantiated wrong
				Transform mark = Instantiate (moveMarker, new Vector3(hitPoint.x, 1, hitPoint.z), Quaternion.identity) as Transform;
				seeker.GetNewPath(transform.position, mark.position);
			}
		}

		if (path == null) {
			return;
		}

		if (currentWaypoint >= path.vectorPath.Count) {
			return;
		}

		Vector3 direction = (path.vectorPath[currentWaypoint]-transform.position).normalized * speed;
		characterController.SimpleMove(direction);

		if (Vector3.Distance (transform.position, path.vectorPath[currentWaypoint]) < maxWaypointDistance) {
			currentWaypoint++;
		}
	}

	void Update() {
		/*if(Input.GetMouseButtonDown(1)) {
			Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
			RaycastHit hitInfo;

			if (Physics.Raycast(ray, out hitInfo)) {
				Vector3 hitPoint = hitInfo.point;

				Transform mark = Instantiate (moveMarker, new Vector3(hitPoint.x, 1, hitPoint.z), Quaternion.identity) as Transform;
				seeker.StartPath(transform.position, mark.position);
			}
		}*/
	}
}

I deleted seeker script because I fixed my previous problem.

Here is my new problem and script. My problem is that the character will not move after I set a new path.

using UnityEngine;
using System.Collections;
using Pathfinding;

public class AIPather : MonoBehaviour {

	Seeker seeker;
	Path path;
	int currentWaypoint;

	float speed = 20f;

	CharacterController characterController;

	float maxWaypointDistance = 2f;

	public Vector3 target;

	public GameObject moveMarker;

	bool markerExists;

	// Use this for initialization
	void Start () {
		seeker = GetComponent<Seeker>();
		seeker.StartPath(transform.position, target, OnPathComplete);
		characterController = GetComponent<CharacterController>();
	}

	public void OnPathComplete(Path p){
		if (!p.error) {
			path = p;
			currentWaypoint = 0;
		}
		else {
			Debug.LogError (p.error);
		}
	}

	void FixedUpdate() {
		if(Input.GetMouseButtonDown(1)) {

			if(markerExists) {
				GameObject prevMarker = GameObject.Find ("_moveMarkerCube(Clone)");
				Destroy (prevMarker);
				Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
				RaycastHit hitInfo;
				
				if (Physics.Raycast(ray, out hitInfo)) {
					Vector3 hitPoint = hitInfo.point;
					
					Transform mark = Instantiate (moveMarker, new Vector3(hitPoint.x, 1, hitPoint.z), Quaternion.identity) as Transform;
					seeker = GetComponent<Seeker>();
					GameObject newMark = GameObject.Find ("_moveMarkerCube(Clone)");
					seeker.StartPath(transform.position, newMark.transform.position, OnPathComplete);
					markerExists = true;
				}
			}

			else {
				Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
				RaycastHit hitInfo;
				
				if (Physics.Raycast(ray, out hitInfo)) {
					Vector3 hitPoint = hitInfo.point;
					
					Transform mark = Instantiate (moveMarker, new Vector3(hitPoint.x, 1, hitPoint.z), Quaternion.identity) as Transform;
					seeker = GetComponent<Seeker>();
					GameObject newMark = GameObject.Find ("_moveMarkerCube(Clone)");
					seeker.GetNewPath(transform.position, newMark.transform.position);
					markerExists = true;
				}
			}
		}

		if (path == null) {
			return;
		}

		if (currentWaypoint >= path.vectorPath.Count) {
			return;
		}

		Vector3 direction = (path.vectorPath[currentWaypoint]-transform.position).normalized * speed;
		characterController.SimpleMove(direction);

		if (Vector3.Distance (transform.position, path.vectorPath[currentWaypoint]) < maxWaypointDistance) {
			currentWaypoint++;
		}
	}

	void Update() {
		/*if(Input.GetMouseButtonDown(1)) {
			Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
			RaycastHit hitInfo;

			if (Physics.Raycast(ray, out hitInfo)) {
				Vector3 hitPoint = hitInfo.point;

				Transform mark = Instantiate (moveMarker, new Vector3(hitPoint.x, 1, hitPoint.z), Quaternion.identity) as Transform;
				seeker.StartPath(transform.position, mark.position);
			}
		}*/
	}

Time to start throwing some Debug.log() 's in there to see if you’re even making it to the move command
