DroneSetting.cs 관련 질문

Drone 환경 만들때 

DroneSetting.cs 스크립트 작성 후 Area 에서 Add Component 에서 Drone Setting 컴포넌트를 추가하니

다음 화면처럼 Drone agent 와 Goal 메뉴가 보이지 않습니다. 

도와 주시면 감사 하겠습니다.

하기는 작성한 DroneSetting.cs 코드 입니다. 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class DroneSetting : MonoBehaviour
{
    private GameObject DroneAgent;
    private GameObject Goal;

    private Vector3 areaInitPos;
    private Vector3 droneInitPos;
    private Quaternion droneInitRot;

    private Transform AreaTrans;
    private Transform DroneTrans;
    private Transform GoalTrans;

    private Rigidbody DroneAgent_Rigidbody;


    void Start()
    {
        AreaTrans = gameObject.transform;
        DroneTrans = DroneAgent.transform;
        GoalTrans = Goal.transform;

        areaInitPos = AreaTrans.position;
        droneInitPos = DroneTrans.position;
        droneInitRot = DroneTrans.rotation;

        DroneAgent_Rigidbody = DroneAgent.GetComponent<Rigidbody>();

    }

    public void AreaSetting()
    {
        DroneAgent_Rigidbody.velocity = Vector3.zero;
        DroneAgent_Rigidbody.angularVelocity = Vector3.zero;

        DroneTrans.position = droneInitPos;
        DroneTrans.rotation = droneInitRot;

        GoalTrans.position = areaInitPos + new Vector3(Random.Range(-5f, 5f), Random.Range(-5f, 5f), Random.Range(-5f, 5f));
        
    }

}
