移动相机并将其旋转到目标游戏对象

  大部分答案都是重复 . 仍然完全重写它为其他读者的背景 .

  您可以获取 points 数组，如下面的脚本所示 . 另外为了保持相机的位置，我采用变量 currentPointIndex 只是为了保持当前点的索引 .

  为了正确旋转，请在协程内使用 Quaternion.RotateTowards(); ，如下面的代码所示

  CameraMotion.cs

  public Transform[] points;
  public int currentPointIndex=0;
  public Transform lookAtTarget;
  
  private void Update()
  {
      if (Input.GetKeyDown(KeyCode.Space))
      {
          StartCoroutine(CameraTransition(points[currentPointIndex],1.0f));
          currentPointIndex++;
      }
  }
  
  IEnumerator CameraTransition(Transform nextPoint,float time)
  {
      float i = 0;
      float rate = 1 / time;
  
      Vector3 fromPos = transform.position;
  
      while (i<1)
      {
          i += Time.deltaTime * rate;
          transform.position = Vector3.Lerp(fromPos,nextPoint.position,i);
  
  
          Quaternion targetRotation = Quaternion.LookRotation(nextPoint.position-transform.position);
          transform.rotation = Quaternion.RotateTowards(transform.rotation,targetRotation,i);
  
          yield return 0;
      }
  }}
  

  基本上，我们循环遍历数组点并相应地进行转换 .

  或者，如果您的点不是线性形式（在数组中），则可以相应地修改逻辑 . 但是你可以使用相同的Co-routine .

  我建议让事情变得更好，首先不要让事情硬编码让它接受更多的对象 . 第二个坚持用更简单的解决方案 .

  using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  
  public class LookAtObject : MonoBehaviour {
  
  public float Speed = 0.001f;
  private Transform _go;
  
  // Update is called once per frame
  void Update ()
  {
      if (_go == null) return;
  
      Vector3 direction = _go.transform.position - transform.position;
      Quaternion toRotation = Quaternion.FromToRotation(transform.forward, direction);
      transform.rotation = Quaternion.Lerp(transform.rotation, toRotation, Speed * Time.time);
  }
  
  public void AdjustOrientation(Transform go)
  {
      _go = go;
  }
  }
  
  
  using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  
  public class OnClick : MonoBehaviour
  {
  private LookAtObject _lookAt;
  
  
  public void Start()
  {
      _lookAt = FindObjectOfType<LookAtObject>();
  }
  
  public void Update()
  {
      if (Input.GetMouseButtonDown(0))
      {
          var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
          RaycastHit hit;
  
          if (Physics.Raycast(ray, out hit, 100))
          {
              //optionally if(hit.collider.tag != "MyTag") return;
              _lookAt.AdjustOrientation(hit.transform);
          }
      }
  }
  }
  

  将这些类放在您的相机上，会发生什么事情是通过AdjustOrientation在您想要查看的对象中获取的第一类 . 更新将在填充后查看该对象 .

  第二类允许您单击包含刚体的场景中的任何对象，并且是Kinematic . 单击对象后，它将设置AdjustOrientations使相机查看该对象，您可以轻松地将标记添加到gameObject并说明hit.collider.tag ==“LookAt”然后允许它查看 .
