如何将对象向上和向下移动？

我应该使用StartCoroutine吗？如何将对象向上和向下移动？

using UnityEngine; 
using System.Collections; 
using System.Reflection; 

public class DetectPlayer : MonoBehaviour { 

    GameObject target; 
    int counter = 0; 
    public static bool touched = false; 

    public float moveSpeed = 3.0f; 
    public float smooth = 1f; 
    private float distanceTravelled; 
    private Vector3 startPositon; 
    public float distanceToTravel = 50; 

    private void Start() 
    { 
     startPositon = new Vector3(target.transform.position.x, target.transform.position.y, target.transform.position.z); 
    } 

    private void Update() 
    { 
     if (RaiseWalls.raised == true && touched == true) 
     { 
      MoveElevator(); 
      //touched = false; 
     } 
    } 

    void OnCollisionEnter(Collision collision) 
    { 
     if (collision.gameObject.name == "ThirdPersonController") // "Platform" 
     { 
      Debug.Log("Touching Platform"); 
     }   
    } 

    void OnTriggerEnter(Collider other) 
    { 
     if (other.gameObject.name == "ThirdPersonController") // "OnTop Detector" 
     { 
      counter = 0; 
      Debug.Log("On Top of Platform"); 
      target = GameObject.Find("Elevator"); 
      GameObject findGo = GameObject.Find("ThirdPersonController"); 
      GameObject findGo1 = GameObject.Find("Elevator"); 
      findGo.transform.parent = findGo1.transform; 

      GameObject go = GameObject.Find("CubeToRaise"); 
      go.GetComponent<RaiseWalls>(); 
      Debug.Log("The button clicked, raising the wall"); 
      touched = true; 
     } 
    } 

    void OnTriggerExit(Collider other) 
    { 
     GameObject findGo = GameObject.Find("ThirdPersonController"); 
     findGo.transform.parent = null; 
    } 

    void MoveElevator() 
    { 
     if (distanceTravelled == distanceToTravel) 
     { 

     } 
     else 
     { 
      target.transform.localPosition += target.transform.up * Time.deltaTime * moveSpeed; 
      distanceTravelled += Vector3.Distance(target.transform.position, startPositon); 
     } 
    } 
}

在这种情况下，MoveElvator功能中的电梯正在向上移动。现在我想让它达到高度50时开始向下移动，并在探测到/到达地面时停止。

，所以我说

if (distanceTravelled == distanceToTravel) 
      { 

      }

，但不知道如何使它向下移动，并停止获取到地面时。

这是C＃不unityscript。顺便说一句，你没有得到答案，因为很难理解你的问题。 “现在我想让它达到50的高度时开始向下移动，并在探测到/到达地面时停止”....你在哪里检测它是否在地面上？ – Programmer

顺便说一句，你的距离旅行是错误的，因为你增加了每一帧旅行的总距离。你应该只有：'distanceTravelled = Vector3.Distance（target.transform.position，startPositon）;' – FINDarkside

您需要保持某种状态，无论电梯是向上，向下还是静止不动。你可以使用枚举为：

enum State{ 
    Idle, 
    MovingUp, 
    MovingDown 
}

现在，你只需要实现向下移动和翻转的方向，当你在顶部或底部。

这里是我的脚本，我使用：

float distance = 50; 
float oneWayDuration; 

void Start() { 
    StartCoroutine(Mover(oneWayDuration, distance)); 
} 

IEnumerator Mover(float oneWayDuration, float yDifference) 
{ 
    Vector3 startPos = transform.position; 
    Vector3 desirePos = new Vector3(startPos.x, startPos.y + 50 , startPos.z); 
    float timeElapsed = 0f; 

    while (timeElapsed < oneWayDuration) 
    { 
     timeElapsed += Time.deltaTime; 
     transform.position = Vector3.Lerp(startPos, desirePos, timeElapsed/oneWayDuration); 
     yield return new WaitForEndOfFrame(); 
    } 
    while (timeElapsed < oneWayDuration) 
    { 
     timeElapsed += Time.deltaTime; 
     transform.position = Vector3.Lerp(desirePos, startPos, timeElapsed/oneWayDuration); 
     yield return new WaitForEndOfFrame(); 
    } 
    //Just in case 
    transform.position = startPos; 
}
