当动态修改Cinemachine Confiner的边界Bounding Shape 2D时，可能会出现BUG。具体表现为，在运行场景前修改了Points数组的值，但在运行场景后，Cinemachine Confiner仍然使用了初始的数组值作为边界。

为了解决这个问题，尝试将另一个具有Polygon Collider 2D组件且设置为Is Trigger为False的物体设置为Cinemachine Confiner的Bounding Shape 2D。这样可以观察到边界是否随之发生变化。

以下是尝试的代码片段：

using UnityEngine;using Cinemachine;public class CameraManager : MonoBehaviour{    [SerializeField] private Transform transform;    [SerializeField] private CinemachineVirtualCamera camera;    [SerializeField] private CinemachineConfiner cinemachineConfiner;    [SerializeField] private PolygonCollider2D polygonCollider;    [SerializeField] private PolygonCollider2D polygonCollider1;    [SerializeField] private int num = 1;    public static CameraManager instance;    void Awake()    {        instance = this;    }    void Start()    {        changeBound();    }    public void changeBound()    {        if (cinemachineConfiner != null && polygonCollider1 != null && polygonCollider != null             && transform != null && camera != null)        {            CinemachineConfiner confiner = new CinemachineConfiner();            Debug.Log("changeBound() - Setting cinemachineConfiner.m_BoundingShape2D to polygonCollider");            cinemachineConfiner.m_Damping = 0f;            cinemachineConfiner.InvalidatePathCache();            if ((num % 2) != 0)            {                cinemachineConfiner.m_BoundingShape2D = null;                confiner.m_BoundingShape2D = polygonCollider1;                //camera.AddExtension(confiner);                //transform.gameObject.AddComponent
   
    ();                //cinemachineConfiner = transform.GetComponent
    
     ();                //cinemachineConfiner = confiner;                //cinemachineConfiner.InvalidatePathCache();                //cinemachineConfiner.m_BoundingShape2D = polygonCollider1;            }            else if ((num % 2) == 0)            {                cinemachineConfiner.m_BoundingShape2D = null;                confiner.m_BoundingShape2D = polygonCollider;                //camera.AddExtension(confiner);                //transform.gameObject.AddComponent
     
      ();                //cinemachineConfiner = transform.GetComponent
      
       ();                //cinemachineConfiner = confiner;                //cinemachineConfiner.InvalidatePathCache();                //cinemachineConfiner.m_BoundingShape2D = polygonCollider;            }            cinemachineConfiner.m_BoundingShape2D = confiner.m_BoundingShape2D;            num++;        }    }}
      
     
    
   

注意事项：

通过以上方法，可以更好地控制Cinemachine Confiner的边界，并解决更新不正确的问题。
