compoent Nav Mesh Agent

• Agent Type : 네비게이션에 적용시킬 collider

• Streering : 운전

• static : navigation static

• navigation tab => bake

patrol 만들기

using UnityEngine.AI;
public class nagivation : MonoBehaviour
{
    Rigidbody MyRigid;
    [SerializeField] private float moveSpeed;
    [SerializeField] private Transform tf_Destination;
    private Vector3 originPos;

    NavMeshAgent agent;
    void Start()
    {
        MyRigid = GetComponent<Rigidbody>();
        agent = GetComponent<NavMeshAgent>();
        originPos = transform.position;
    }

    private void Patrol()
    {
        if (Vector3.Distance(transform.position, tf_Destination.position) < 0.1f)
            agent.SetDestination(originPos);
        else if (Vector3.Distance(transform.position, originPos) < 0.1f)
            agent.SetDestination(tf_Destination.position);
    }
    void Update()
    {
        Patrol();
    }
}
