Unity中实现⼈物相机跟随，镜头旋转
参考⾃：
挂在⼈物上的：MoveController.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MoveController : MonoBehaviour {
public float speed = 6.0F; //⼈物移动速度
public float jumpSpeed = 5.0F;
public float gravity = 5.0F;
private Vector3 moveDirection = ;
public float rotatinDamping = 4; //⼈物旋转的速度
public float mou1RotateDamping = 4;
public bool cameraIsRotate = true; //判断相机是否跟随⼈物旋转（点击⿏标左键可观看⾓⾊）
private float backgroundRotateValue; //点击⿏标右键，存储⿏标X⽅向位移
float currentOnClickMou1AngleY = 0; //⿏标右击时⼈物当前的Y轴度数
boarfloat currentCameraAngleY = 0; //⿏标左击时相机当前的Y轴度数
public GameObject cam; //⼈物后⾯的相机
private CharacterController characterContro; //⾓⾊控制器组件
// U this for initialization
void Start()
{
characterContro = this.GetComponent<CharacterController>();
cam = GameObject.Find("Main Camera");
}
// Update is called once per frame
void Update()
{
move();
mouControllerRotation();
}
void move()
{
CharacterController controller = GetComponent<CharacterController>();
if (controller.isGrounded)
{
moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
moveDirection = transform.TransformDirection(moveDirection);英文艺术字
moveDirection *= speed;
if (Input.GetButton("Jump"))
moveDirection.y = jumpSpeed;
}
moveDirection.y -= gravity * Time.deltaTime;
controller.Move(moveDirection * Time.deltaTime);
}

void mouControllerRotation()
{
if (Input.GetMouButtonDown(1))
{
currentOnClickMou1AngleY = transform.eulerAngles.y;
backgroundRotateValue = 0;
}
if (Input.GetMouButton(1))
{
backgroundRotateValue += Input.GetAxis("Mou X") * mou1RotateDamping;

transform.eulerAngles = new Vector3(transform.eulerAngles.x, backgroundRotateValue + currentOnClickMou1AngleY, transform.eulerAngles.z);

}
}
挂在相机上的：

using System.Collections.Generic;

private float offt; //镜头左右旋转的差值
private float distance; //相机和⽬标的距离
private bool cameraIsRotate;
private float oldRotationAngle;
//private float height = 1f; //相机和⽬标的⾼度
//private float heightDamping = 1;
// Vector3 offtPosition;
// U this for initialization
void Start()
{
offt = 0;
cameraIsRotate = true;
target = GameObject.Find("Player_archer_arrow_master").transform;
oldRotationAngle = transform.eulerAngles.y;
mc = target.gameObject.GetComponent<MoveController>();
distance = Vector3.Distance(new Vector3(0, 0, target.position.z), new Vector3(0, 0, transform.position.z));
//offtPosition = target.position - transform.position;
}
// Update is called once per frame
void Update()
{
//transform.position = target.position - offtPosition;

/
/float currentHeight = transform.position.y; //当前的⾼度
if (cameraIsRotate)
{
currentRotationAngle = Mathf.LerpAngle(currentRotationAngle, wantedRotationAngle, rotationDamping * Time.deltaTime); }
// currentHeight = Mathf.Lerp(currentHeight, wantedHeight, heightDamping * Time.deltaTime); //由当前⾼度达到要达到的⾼度 Quaternion currentRotation = Quaternion.Euler(transform.eulerAngles.x, currentRotationAngle, 0);
// float currentRotation=1; //防⽌主⾓回头摄像机发⽣旋转，这⾥不⽤
Vector3 ca = target.position - currentRotation * Vector3.forward * distance; //tt是相机的位置
// transform.position = target.position-currentRotation * Vector3.forward * distance;
transform.position = new Vector3(ca.x, transform.position.y, ca.z); //最后得到的相机位置
// transform.LookAt(target.position);

distance -= scrollWheel;
if (distance > 5.6f)

{
distance = 5.6f;
}
if (distance < 0.9f)

思路：
两种镜头旋转⽅式：
1.只旋转⼈物
2.只旋转背景。
需要带有拉近拉远镜头的功能。
旋转⼈物的时候就要把相机位置锁死，⽽旋转背景的时候，左右旋转要把相机的Y位置锁死，上下旋转的时候要把相机的X，Z位置分别锁死。
update⾥⾯要不断更新相机的位置，可以⽤offt（相机和⼈物的相对位置，向量差）。
⽽旋转⼈物的时候简单，offt不变。
旋转背景时，左右旋转，只修改offt的Y向量，（更新相机的Y位置，然后相减）。
上下旋转同理只修改offt的X，Z位置。
这样就实现了相机的跟随和镜头旋转。
