I am working on setting up a simple little AI for a character in my game. For some reason I am having major problems getting animations to play while using the NavMeshAgent and I do not understand why. This is a waypoint system that I pooled off Unity API, and I can't even seem to get this working. I am hoping that if someone can give me some input on this if might clear some other things up as well. I am really lost here and would appreciate any input. The code on the bottom all works until it hits Patrol and then the player moves without animating. I feel like there is something more i need to know about navmesh's maybe. Or a lot more I need to know about programming in general.
e// Patrol.cs
using UnityEngine;
using UnityEngine.AI;
using System.Collections;
public class Enemy_Patrol : MonoBehaviour
{
public Transform[] points;
public Animator anim;
private int destPoint = 0;
private NavMeshAgent agent;
void Start()
{
agent = GetComponent<NavMeshAgent>();
anim = GetComponent<Animator>();
// Disabling auto-braking allows for continuous movement
// between points (ie, the agent doesn't slow down as it
// approaches a destination point).
agent.autoBraking = false;
GotoNextPoint();
}
void GotoNextPoint()
{
// Returns if no points have been set up
if (points.Length == 0)
return;
// Set the agent to go to the currently selected destination.
agent.destination = points[destPoint].position;
anim.SetBool("WalkForwards", true);
anim.SetBool("IsIdle", false);
// Choose the next point in the array as the destination,
// cycling to the start if necessary.
destPoint = (destPoint + 1) % points.Length;
}
void Update()
{
// Choose the next destination point when the agent gets
// close to the current one.
if (!agent.pathPending && agent.remainingDistance < 0.5f)
GotoNextPoint();
}
}
// Code i wrote to handle following chasing etc.

You are calling WaitingOnAction on Update every frame, which will set the animator's IsIdle back to true and start a new BackToPatrol coroutine. This should not happen. Try to check if the character has reached it's destination before calling WaitingOnAction again. Something like:
else if (Vector3.Distance(player.position, this.transform.position) > 30 && !isPatrolling)
{
WaitingOnAction();
}
And in your Coroutine:
IEnumerator BackToPatrol()
{
isPatrolling = true;
yield return new WaitForSeconds(5);
anim.SetBool("IsIdle", false);
yield return StartCoroutine("Patrol");
isPatrolling = false;
}
IEnumerator Patrol()
{
Debug.Log("In Patrol");
agent.speed = patrolSpeed;
agent.SetDestination(waypoints[waypointInd].transform.position);
anim.SetBool("WalkForwards", true);
agent.isStopped = false;
while (Vector3.Distance(this.transform.position, waypoints[waypointInd].transform.position) >= 2 && isPatrolling)
{
yield return null;
}
agent.isStopped = true;
anim.SetBool("WalkForwards", false);
waypointInd++;
if(waypointInd >= waypoints.Length) waypointInd = 0;
}
I didn't test it, but something like this should work.
