Animation and Nav Mesh Agent - rotation problem

Questions & Answers

Hi

I’m trying to create a AI enemy by using Nav Mesh Agent and animation controller.
When I setup basic AI and Nav Mesh Agent enemy follows very well. But I don’t know how to properly add animation. I have a Idle and walk animation. Idle works good. The problem is that when I add a walk animation enemy can’t turn.

This is a C# code for AI:

public class Enemy_Pursuit : MonoBehaviour
    {
        public LayerMask detectionLayer;

        private Animator anim;
        private Transform myTransform;
        private NavMeshAgent myNavMeshAgent;
        private Collider[] hitColliders;
        private float checkRate;
        private float nextCheck;
        private float detectionRadius = 5;

        // Use this for initialization
        void Start()
        {
            
            SetInitialReferences();
        }

        // Update is called once per frame
        void Update()
        {
            CheckIfPlayerInRange();
        }

        void SetInitialReferences()
        {
            myTransform = transform;
            anim = GetComponent<Animator>();
            myNavMeshAgent = GetComponent<NavMeshAgent>();
            checkRate = 0.7f;
        }

        void CheckIfPlayerInRange()
        {
            if((Time.time > nextCheck) && (myNavMeshAgent.enabled == true))
            {
                nextCheck = Time.time + checkRate;
                hitColliders = Physics.OverlapSphere(myTransform.position, detectionRadius, detectionLayer);

                if(hitColliders.Length > 0)
                {
                    myNavMeshAgent.SetDestination(hitColliders[0].transform.position);
                }
            }
        }
    }

Ok, so I find a solution for my problem.
I changed code from this topic:

Now it looks like this:

public class Enemy_Pursuitv2 : MonoBehaviour
        {
            private NavMeshAgent agent;
            public float rotationSpeed = 10f;
            Transform target;
    
            void Start()
            {
                agent = GetComponent<NavMeshAgent>();
                GameObject player = GameObject.Find("Player");
                target = player.transform;
            }
    
            void Update()
            {
    
                // Code here that decides what target is
    
                MoveTowards(target);
                RotateTowards(target);
            }
            private void MoveTowards(Transform target)
            {
                agent.SetDestination(target.position);
            }
    
            private void RotateTowards(Transform target)
            {
                Vector3 direction = (target.position - transform.position).normalized;
                Quaternion lookRotation = Quaternion.LookRotation(direction);
                transform.rotation = Quaternion.Slerp(transform.rotation, lookRotation, Time.deltaTime * rotationSpeed);
            }
        }

Then I added walk animation to animation controller and it works :slight_smile:
