Unity 相机平移、旋转、缩放

内容不多，一个脚本，直接上代码

 1 using System.Collections;
 2 using System.Collections.Generic;
 3 using UnityEngine;

 5 public class Move : MonoBehaviour

 8     float speed = 20;

11     public float rotation_H_speed = 1;
12     public float rotation_V_speed = 1;
13     public float max_up_angle = 80;              //越大，头抬得越高
14     public float max_down_angle = -60;           //越小，头抬得越低
15
16
17     private float current_rotation_H;  //水平旋转结果
18     private float current_rotation_V;  //垂直旋转结果
19     void LateUpdate()
20     {
21         // 旋转
22         if (Input.GetMouseButton(1))
23         {

27             //current_rotation_V = Mathf.Clamp(current_rotation_V, max_down_angle, max_up_angle);       //限制垂直旋转角度

30             transform.Translate(Vector3.up * distance_v, Space.World);          //相对于世界坐标y轴向上
31         }
32

43     }
44

46     void Update()

49         if (Input.GetKey(KeyCode.A)) //左移
50         {
51             transform.Translate(Vector3.left * speed * Time.deltaTime);
52         }
53         if (Input.GetKey(KeyCode.D)) //右移
54         {

70         if (Input.GetAxis("Mouse ScrollWheel") != 0)
71         {
72             //获取鼠标滚轮的滑动量
73             float wheel = Input.GetAxis("Mouse ScrollWheel") * Time.deltaTime * 5000;
74
75             //改变相机的位置
76             this.transform.Translate(Vector3.forward * wheel);
