如何將地形上的所有球體從原始位置移動到新位置，然後回到原來的循環中？

Question

我想要它做的是在編輯器和運行遊戲時看到所有的球體在同一時間移動到另一個方向，或者它將是相同的方向直到endPoint，然後回到循環中的startPoint沒有停止。

這是我的腳本：

using System; 
using UnityEngine; 
using Random = UnityEngine.Random; 

[ExecuteInEditMode] 
public class SphereBuilder : MonoBehaviour 
{ 
    // for tracking properties change 
    private Vector3 _extents; 
    private int _sphereCount; 
    private float _sphereSize; 

    /// <summary> 
    ///  How far to place spheres randomly. 
    /// </summary> 
    public Vector3 Extents; 

    /// <summary> 
    ///  How many spheres wanted. 
    /// </summary> 
    public int SphereCount; 

    public float SphereSize; 

    private void OnValidate() 
    { 
     // prevent wrong values to be entered 
     Extents = new Vector3(Mathf.Max(0.0f, Extents.x), Mathf.Max(0.0f, Extents.y), Mathf.Max(0.0f, Extents.z)); 
     SphereCount = Mathf.Max(0, SphereCount); 
     SphereSize = Mathf.Max(0.0f, SphereSize); 
    } 

    private void Reset() 
    { 
     Extents = new Vector3(250.0f, 20.0f, 250.0f); 
     SphereCount = 100; 
     SphereSize = 20.0f; 
    } 

    private void Update() 
    { 
     UpdateSpheres(); 
    } 

    private void UpdateSpheres() 
    { 
     if (Extents == _extents && SphereCount == _sphereCount && Mathf.Approximately(SphereSize, _sphereSize)) 
      return; 

     // cleanup 
     var spheres = GameObject.FindGameObjectsWithTag("Sphere"); 
     foreach (var t in spheres) 
     { 
      if (Application.isEditor) 
      { 
       DestroyImmediate (t); 
      } 
      else 
      { 
       Destroy(t); 
      } 
     } 

     var withTag = GameObject.FindWithTag("Terrain"); 
     if (withTag == null) 
      throw new InvalidOperationException("Terrain not found"); 

     for (var i = 0; i < SphereCount; i++) 
     { 
      var o = GameObject.CreatePrimitive(PrimitiveType.Sphere); 
      o.tag = "Sphere"; 
      o.transform.localScale = new Vector3(SphereSize, SphereSize, SphereSize); 

      // get random position 
      var x = Random.Range(-Extents.x, Extents.x); 
      var y = Extents.y; // sphere altitude relative to terrain below 
      var z = Random.Range(-Extents.z, Extents.z); 

      // now send a ray down terrain to adjust Y according terrain below 
      var height = 10000.0f; // should be higher than highest terrain altitude 
      var origin = new Vector3(x, height, z); 
      var ray = new Ray(origin, Vector3.down); 
      RaycastHit hit; 
      var maxDistance = 20000.0f; 
      var nameToLayer = LayerMask.NameToLayer("Terrain"); 
      var layerMask = 1 << nameToLayer; 
      if (Physics.Raycast(ray, out hit, maxDistance, layerMask)) 
      { 
       var distance = hit.distance; 
       y = height - distance + y; // adjust 
      } 
      else 
      { 
       Debug.LogWarning("Terrain not hit, using default height !"); 
      } 

      // place ! 
      o.transform.position = new Vector3(x, y, z); 
     } 

     _extents = Extents; 
     _sphereCount = SphereCount; 
     _sphereSize = SphereSize; 
    } 
} 

更新

我創造了另一個C＃腳本，並將其拖動到地形。

using UnityEngine; 
using System.Collections; 

public class MoveSpheres : MonoBehaviour { 

    public Transform _transform; 
    private Vector3 pos1 = new Vector3(-4,0,0); 
    private Vector3 pos2 = new Vector3(4,0,0); 
    public float speed = 1.0f; 
    // Use this for initialization 
    void Start() { 



    } 

    // Update is called once per frame 
    void Update() { 

     _transform.position = Vector3.Lerp (pos1, pos2, Mathf.PingPong(Time.time*speed, 1.0f)); 


    } 
} 

此腳本移動一個球體。但是我想移動所有的球體。 而且，如果我在第一個腳本中更改了球體的數量，那麼它們也會移動它們。

問題出在第一個腳本中的Destroy部分。

可以線性插值從一個位置球到另一個和背部https://docs.unity3d.com/ScriptReference/Vector3.Lerp.html
