        agent = GetComponent<NavMeshAgent>();

        animator = GetComponent<Animator>();

        //Debug.Log(player.transform.position);

        float distance = Vector3.Distance(transform.position, player.transform.position);

        if (distance < distance2Chase)

        {

            if (distance > distanceEnemy)

            {

                agent.isStopped = false;

                agent.SetDestination(player.transform.position);

            }
