实现键盘对Camera的控制

控制的一些API：https://docs.unity3d.com/550/Documentation/ScriptReference/Input.html

在Camera编写c#，实现对镜头的控制：

using System.Collections;using System.Collections.Generic;using UnityEngine;public class decret : MonoBehaviour {    public float speed =2f;    public float Mousespeed=600;// Use this for initializationvoid Start () {}// Update is called once per framevoid Update () {        float mouse =Input.GetAxis("Mouse Scrollwheel");//这是控制鼠标的滚轮的        float h = Input.GetAxis("Horizontal") * Time.deltaTime * speed;        float v = Input.GetAxis("Vertical") * Time.deltaTime * speed;        Vector3 move = new Vector3(h*speed,mouse*Mousespeed,v*Mousespeed)*Time.timedelet;        //transform.Translate(move);}}
