运行时可手动旋转摄像机脚本
首先把摄像机设置成摄像机盒子，如图
Obj XuNiTi 是3Dmax导出的fbx添加虚拟体如果有虚拟体，相机可以跟随虚拟体运行，FollowState 状态为1
Angles 是相机的旋转角度 可代码设置
Angles Speed 相机旋转速度
TargetHeight 目标高度
DistanceSpeed 缩放时的速度
Distance 相机初始位置 0.1是最小距离 30是最大距离
FollowState 0 定点的不能移动旋转 1 跟随虚拟体 2 自由视角
脚本如下 挂在CameraCube上即可

第二个版本
只需要MainCamera 脚本挂上即可
脚本如下
1 using UnityEngine; 2 using System.Collections; 3 4 public class RotateCamera : MonoBehaviour 5 { 6 public Transform target; 7 8 //距离 9 public float distanceX = 0; 10 public float distanceY = 0; 11 public float distanceZ=-5; 12 public float minDistance = -2; 13 public float maxDistance =-50; 14 15 //角度 16 public float angleX=30f; 17 public float angleY=0; 18 public float angleZ=0; 19 20 public float angleSpeed = 5f; 21 public float scrollSpeed = 5f; 22 public float moveSpeed = 5f; 23 24 // Use this for initialization 25 void Start () 26 { 27 Debug.Log(Quaternion.Euler(0, 90, 0)); 28 Debug.Log(Quaternion.Euler(0, 90, 0)*new Vector3(0, 0, -10)); 29 } 30 31 // Update is called once per frame 32 void Update () 33 { 34 Mouse(); 35 UpdateCamera(); 36 } 37 38 private void Mouse() 39 { 40 if (Input.GetMouseButton(1)) 41 { 42 angleY += Input.GetAxis("Mouse X")*angleSpeed; 43 angleX -= Input.GetAxis("Mouse Y")*angleSpeed; 44 } 45 if (Input.GetAxis("Mouse ScrollWheel") != 0) 46 { 47 //根据鼠标滚轮的值计算出这一帧应该移动的距离。 48 distanceZ += Mathf.Lerp(0, Input.GetAxis("Mouse ScrollWheel")*scrollSpeed, Time.deltaTime); 49 distanceZ = Mathf.Clamp(distanceZ,maxDistance, minDistance); 50 } 51 if (Input.GetMouseButton(2)) 52 { 53 //根据鼠标滑动的值计算出这一帧一个移动的距离 54 distanceX -= Mathf.Lerp(0, Input.GetAxis("Mouse X") * moveSpeed, Time.deltaTime); 55 distanceY -= Mathf.Lerp(0, Input.GetAxis("Mouse Y") * moveSpeed, Time.deltaTime); 56 } 57 } 58 59 private void UpdateCamera() 60 { 61 Quaternion rotation=Quaternion.Euler(angleX,angleY,angleZ); 62 63 //创建一个位移变量 64 Vector3 pos=new Vector3(distanceX,distanceY,distanceZ); 65 66 Vector3 postion = rotation * pos; 67 if (target != null) 68 postion += target.position; 69 70 transform.position = postion; 71 transform.rotation = rotation; 72 } 73 }
