NavMeshAgent stopping before reaching destination

Hi guys,
I am currently making a click to move game using Mecanim to compute movement, a script to set rotation and NavMeshAgent to set the destination.


However, from time to time, the character would not start moving after the destination has been set as shown on the image. The small red circle is the destination and some random yellow lines appear. No error appears on the console but I do have to click on the ground again so the character can start moving. The code is based on the adventure tutorial from Unity and some minor modifications were made.

Code (CSharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class PlayerController : MonoBehaviour {
6.     UnityEngine.AI.NavMeshAgent agent;
7.     Animator anim;
8.     CharacterStats player;
9.     public GameObject cube;
10.  
11.     void Start () {
12.         agent = GetComponent<UnityEngine.AI.NavMeshAgent>();
13.         agent.updateRotation = false;
14.         anim = GetComponent<Animator>();
15.     }
16.    
17.     void Update () {
18.         if (agent.pathPending)
19.         {
20.             return;
21.         }
22.         if (Input.GetMouseButtonDown(0))
23.         {
24.             Interact();
25.             Debug.Log("clicked");
26.         }    
27.         float speed = agent.desiredVelocity.magnitude;
28.         if (agent.remainingDistance<=0)
29.         {
30.             agent.Stop();
31.             speed = 0;
32.             Debug.Log("no path");
33.         }    
34.                
35.         Moving();
36.         Debug.Log("moving");
37.        
38.         anim.SetFloat("Speed", speed, 0.1f, Time.deltaTime);
39.     }
40.  
41.     private void OnAnimatorMove()
42.     {
43.         agent.velocity = anim.deltaPosition / Time.deltaTime;
44.     }
45.  
46.     private void Moving()
47.     {
48.    
49.         Quaternion targetRotation = Quaternion.LookRotation(agent.desiredVelocity);
50.         transform.rotation = Quaternion.Lerp(transform.rotation, targetRotation, 10 * Time.deltaTime);
51.     }
52.  
53.     void Interact()
54.     {
55.         Ray interacRay = Camera.main.ScreenPointToRay(Input.mousePosition);
56.         RaycastHit hit;
57.        
58.  
59.         if(Physics.Raycast(interacRay,out hit, Mathf.Infinity))
60.         {
61.             agent.SetDestination(hit.point);
62.             agent.Resume();
63.         }
64.     }
65. }

 

You may have overthought this. If you want to set the rotation of the navmeshagent, set it through the "angular speed" variable. If you want to animate it, check out this link:
