🎶（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;}}}

public class PlayerMove : MonoBehaviour
{private float vertical;private float horizontal;private float mousePosition;private CharacterController player; //角色控制器private Vector3 moveDerictor;       //移动的方向public  float  velocity = 2f;       //移动的速度public  float roVelocity = 10f;private Animator playerAnimatior;private void Awake(){player = GetComponent<CharacterController>();playerAnimatior = GetComponent<Animator>();}private void FixedUpdate(){vertical   =  Input.GetAxis("Vertical") ;horizontal =  - Input.GetAxis("Horizontal") ;mousePosition = Input.GetAxis("Mouse X");//旋转transform.localRotation *= Quaternion.Euler(0, mousePosition * roVelocity, 0);if (vertical != 0 ||horizontal != 0){        //移动playerAnimatior.SetFloat("SpeedWS", (int)vertical);playerAnimatior.SetFloat("SpeedAD", (int)horizontal);moveDerictor = new Vector3(vertical, 0, horizontal);print(moveDerictor.normalized);/// moveDerictor = moveDerictor.normalized;   //将方向变成单位向量//transform.position= transform.position + moveDerictor.normalized*Time .deltaTime ;player.SimpleMove(transform.forward * vertical );player.SimpleMove(transform.right * -horizontal);//GetComponent<Rigidbody>().MovePosition( transform.localPosition + moveDerictor * velocity * Time.deltaTime); //速度*方向 = 向量//此时物体并非跟着自己的旋转方向进行移动而是根据自身位置进行改变//（白话：无法变成FPS的第一视角进行当前视角当前前进）       }}private void MouseRotation(){}}

---

🎶（6）相机 Lerp差值跟随

---

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