本文介绍了一个Unity脚本，用于实现摄像机的缩放和平移功能。通过鼠标滚轮进行视角缩放，利用鼠标左键拖动调整摄像机锚点位置，从而实现游戏视窗的平移效果。

需要安装一下cinemachine插件

using Cinemachine;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

/// <summary>
/// 用于控制anchor的位置
/// </summary>
public class CameraNew : MonoBehaviour
{
    public Transform upleft;
    public Transform downright;
    public Transform anchor;

    public CinemachineVirtualCamera CMvam1;

    private float zoomMax =12;
    private float zoomMin = 3;
    private float zoomCurrent = 12.0f;
    private float zoomSpeed = 2;
    private bool bInTouch = false;
    public bool camPanningUse = true;

    private Vector3 anchorPosOld = Vector3.zero;
    private Vector3 mousePosOld = Vector3.zero;
    private Vector3 mousePosLast = Vector3.zero;

    void Start()
    {
        CMvam1= (CinemachineVirtualCamera)Camera.main.GetComponent<CinemachineBrain>().ActiveVirtualCamera;
    }



    void Update()
    {
        //视角缩小
        zoomCurrent -= Input.GetAxis("Mouse ScrollWheel") * zoomSp
