🎶（1） 挂载于父对象上进行跟随

---

---

🎶（2）位置定点跟随，滑轮改变视野

---

😶‍🌫️效果:
摄像机需要实现跟随，车同步移动，旋转。并且滑动鼠标滑轮可以调节与车辆之间的摄影距离。

public class CameraFllow : MonoBehaviour
{//目标物体public Transform target;//鼠标滑轮的速度public float ScrollSpeed = 4f;//Y轴差距参数public float Ydictance = 0f; public float  Ymin = 0f;public float  Ymax  = 4f;//Z轴差距参数public float Zdictance = 4f;public float Zmin = 4f;public float Zmax = 8f;//相机看向的角度 和最終位置public float angle = -25 ;public Vector3 lookPosition;void LateUpdate(){//Z轴和Y轴的距离和鼠标滑轮联系Ydictance += Input.GetAxis("Mouse ScrollWheel") * ScrollSpeed;Zdictance += Input.GetAxis("Mouse ScrollWheel") * ScrollSpeed;//設置Y軸和x轴的滚轮滑动范围Ydictance = Mathf.Clamp(Ydictance , Ymin ,Ymax );Zdictance = Mathf.Clamp(Zdictance , Zmin, Zmax );//确定好角度，四元数 * 三维向量 = 三维向量lookPosition = Quaternion.AngleAxis(angle, target .right) * -target.forward ;//更新位置transform.position = target.position + Vector3.up * Ydictance - lookPosition  * Zdictance  ;//更新角度transform.rotation = Quaternion.LookRotation(lookPosition);}
}

---

🎶（3） 距离差值进行跟随

---

public class CameraMove : MonoBehaviour
{public Transform target; //跟随的目标物体private Vector3 offset;  //位置偏移差void Start(){offset = transform.localPosition - target.transform.localPosition;}private void FixedUpdate(){if (target){transform.rotation = target.rotation ;transform.rotation *= Quaternion.AngleAxis(-15, Vector3.left);transform.position = target.transform.localPosition + offset;}}}

---

🎶（4） LookAt上帝视角的跟随

---

public class CameraMove : MonoBehaviour
{public Transform target; //跟随的目标物体private Vector3 offset;  //位置偏移差void Start(){offset = transform.localPosition - target.transform.localPosition;}private void FixedUpdate(){if (target){           transform.rotation = target.rotation ;           transform.position = target.transform.localPosition + offset;transform.LookAt(target.position +Vector3 .up*3);}}}

---

🎶（5）相机的第一/三人称跟随（添加了跟随点）

---

• 为了实现相机和人物的镜头旋转保持一致，（达到相机作为子对象的效果）
• 所以只需要再父对象中添加一个跟随点作为其子对象
  
  

public class CameraMove : MonoBehaviour
{public Transform target; //跟随的目标物体private Vector3 offset;  //位置偏移差void Start(){offset = transform.position - target.GetChild(0).position;//target的第一个子对象是相机的跟随点}private void FixedUpdate(){if (target){           transform.rotation = target.GetChild(0).rotation ;           transform.position = target.GetChild(0).position+ offset;transform.LookAt(target.position + Vector3 .up*2.5f);///transform.rotation = target.rotation;}}}

---

🎶（6）相机 Lerp差值跟随

---

     transform.position = Vector3.Lerp(transform.position, target[ChooseIndex].position, Time.deltaTime * speed);transform.LookAt(targetOb );
