Unity中摄像机跟随

一、固定相机跟随，这种相机有一个参考对象，它会保持与该参考对象固定的位置，跟随改参考对象发生移动

public class CameraFlow : MonoBehaviour
{public Transform target;private Vector3 offset;void Start(){//设置相对偏移offset = target.position - this.transform.position;}void FixedUpdate(){this.transform.position = target.position - offset;}
}

二、固定相机跟随，带有角度旋转。这一种相机跟随是对第一种相机跟随的改进，在原有基础上面，添加了跟随角度的控制

public class CameriaTrack : MonoBehaviour
{private Vector3 offset = new Vector3(0,5,4);//相机相对于玩家的位置private Transform target;private Vector3 pos;public float speed = 2;void Start () {target = GameObject.FindGameObjectWithTag("Player").transform;}void FixedUpdate() {pos = target.position + offset;this.transform.position = Vector3.Lerp(this.transform.position, pos, speed*Time.deltaTime);//调整相机与玩家之间的距离Quaternion angel = Quaternion.LookRotation(target.position - this.transform.position);//获取旋转角度this.transform.rotation = Quaternion.Slerp(this.transform.rotation, angel, speed * Time.deltaTime);}
}

三、第三人称相机,这种相机跟随，是第三人称角度看向对象的，也就是一直看向对象的后面，如一直显示玩家的后背

 public Transform target;public float distanceUp = 10f;//相机与目标的竖直高度参数public float distanceAway = 10f;//相机与目标的水平距离参数public float smooth = 2f;//位置平滑移动插值参数值public float camDepthSmooth = 20f;void Update(){// 鼠标轴控制相机的远近if ((Input.mouseScrollDelta.y < 0 && Camera.main.fieldOfView >= 3) || Input.mouseScrollDelta.y > 0 && Camera.main.fieldOfView <= 80){Camera.main.fieldOfView += Input.mouseScrollDelta.y * camDepthSmooth * Time.deltaTime;}}void LateUpdate(){//计算出相机的位置Vector3 disPos = target.position + Vector3.up * distanceUp - target.forward * distanceAway;transform.position = Vector3.Lerp(transform.position, disPos, Time.deltaTime * smooth);//相机的角度transform.LookAt(target.position);}

四、相机跟随，鼠标控制移动和缩放。相机与观察对象保持一定距离，可以通过鼠标进行上下左右旋转，通过鼠标滚轮进行放大和缩小操作

using UnityEngine;
using System.Collections;
using UnityEngine.EventSystems;public class target_control : MonoBehaviour {public Transform _target;public float distance = 50.0f;public float xSpeed = 250.0f;public float ySpeed = 120.0f;public int yMinLimit = -20;public int yMaxLimit = 80;private bool orbit = false;private bool pan = false;private bool zoom = false;private float zoomValue = 0;public float orbitDampX = 0.0f;public float orbitDampY = 0.0f;float panDampX = 0.0f;float panDampY = 0.0f;public float zoomDamp = 0.0f;public float dampingTime = 0.0f;public float x = 180.0f;public float y = 0.0f;public int planFactor = 5;public float zoomFactor = 2.0f;public Vector2 distLimit;public static Quaternion _rotation;public static Vector3 _position;public static target_control _target_control;public float _z_distance;private Vector3 angles;private Vector2 oldPosition1;   private Vector2 oldPosition2;public float _target_distance = 5;private float target_x;private float target_y;private Vector3 _target_pos = Vector3.zero;public bool change_distance() {distance = Mathf.Lerp(distance, _target_distance, 0.04f);Debug.Log(distance + "/" + _target_distance);updateCamera();if (Mathf.Abs(distance - _target_distance) < 0.01f)return false;return true;}public bool change_distance(float _dis){distance = Mathf.Lerp(distance, _dis, 0.004f);updateCamera();if (Mathf.Abs(distance - _dis) < 0.01f)return false;return true;}void Start(){_target_distance = distance;_z_distance = distance;angles = transform.eulerAngles;x = angles.y;y = angles.x;// Make the rigid body not change rotationif (GetComponent<Rigidbody>())GetComponent<Rigidbody>().freezeRotation = true;}// Update is called once per framevoid LateUpdate () {if (EventSystem.current.IsPointerOverGameObject()||_target ==null){return;}if (Application.platform == RuntimePlatform.IPhonePlayer){if (Input.touchCount == 1){if (Input.GetTouch(0).phase == TouchPhase.Moved){orbit = true;}else{orbit = false;}}else{orbit = false;}if (Input.touchCount > 1){if (Input.GetTouch(0).phase == TouchPhase.Moved || Input.GetTouch(1).phase == TouchPhase.Moved){var tempPosition1 = Input.GetTouch(0).position;var tempPosition2 = Input.GetTouch(1).position;if (isEnlarge(oldPosition1, oldPosition2, tempPosition1, tempPosition2)){zoomValue = 0.1f;zoom = true;}else{zoomValue = -0.1f;zoom = true;}oldPosition1 = tempPosition1;oldPosition2 = tempPosition2;}else{zoom = false;}}else{zoom = false;}} else if (Application.platform == RuntimePlatform.Android){if (Input.touchCount == 1){if (Input.GetTouch(0).phase == TouchPhase.Moved){orbit = true;}else{orbit = false;}}else{orbit = false;}if (Input.touchCount > 1){if (Input.GetTouch(0).phase == TouchPhase.Moved || Input.GetTouch(1).phase == TouchPhase.Moved){var tempPosition1 = Input.GetTouch(0).position;var tempPosition2 = Input.GetTouch(1).position;if (isEnlarge(oldPosition1, oldPosition2, tempPosition1, tempPosition2)){zoomValue = 0.1f;zoom = true;}else{zoomValue = -0.1f;zoom = true;}oldPosition1 = tempPosition1;oldPosition2 = tempPosition2;}else{zoom = false;}}else{zoom = false;}}else{if (Input.GetMouseButton(1)){orbit = true;}else{orbit = false;}if (Input.GetAxisRaw("Mouse ScrollWheel") != null){zoomValue = Input.GetAxisRaw("Mouse ScrollWheel");zoom = true;}else{zoom = false;}}if (orbit){orbitDampX = Mathf.Lerp(orbitDampX, Input.GetAxis("Mouse X"), dampingTime * Time.deltaTime);orbitDampY = Mathf.Lerp(orbitDampY, Input.GetAxis("Mouse Y"), dampingTime * Time.deltaTime);}else{orbitDampX = Mathf.Lerp(orbitDampX, 0, dampingTime * Time.deltaTime);orbitDampY = Mathf.Lerp(orbitDampY, 0, dampingTime * Time.deltaTime);}if (zoom){zoomDamp = Mathf.Lerp(zoomDamp, zoomValue, dampingTime * Time.deltaTime);}else{zoomDamp = Mathf.Lerp(zoomDamp, 0, dampingTime * Time.deltaTime);}if (!checkLerp(orbitDampX, 0) || !checkLerp(orbitDampY, 0)){doOrbit();}if (!checkLerp(zoomDamp, 0)){doZoom();}}bool isEnlarge(Vector2 oP1,Vector2 oP2 , Vector2 nP1, Vector2 nP2 )  {   var leng1 =Mathf.Sqrt((oP1.x-oP2.x)*(oP1.x-oP2.x)+(oP1.y-oP2.y)*(oP1.y-oP2.y));   var leng2 =Mathf.Sqrt((nP1.x-nP2.x)*(nP1.x-nP2.x)+(nP1.y-nP2.y)*(nP1.y-nP2.y));   if(leng1<leng2)   {   //bigreturn true;    }else   {   //smallreturn false;    }   }bool checkLerp(float a,float b){if (Mathf.Approximately(a, b)){return true;}return false;}void doOrbit(){if (_target) {            x += orbitDampX * xSpeed * 0.02f;y -= orbitDampY * ySpeed * 0.02f;y = ClampAngle(y, yMinLimit, yMaxLimit);updateCamera();}}void doZoom(){distance -= zoomDamp * zoomFactor;distance = Mathf.Clamp(distance, -distLimit.x, distLimit.y);updateCamera();}void updateCamera(){var rotation = Quaternion.Euler(y, x, 0);var position = rotation * new Vector3(0.0f, 0.0f, -distance) + _target.position;transform.rotation = rotation;transform.position = position;}static float ClampAngle (float angle,float min,float max){if (angle < -360)angle += 360;if (angle > 360)angle -= 360;return Mathf.Clamp(angle, min, max);}
