//代码

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

public class CameraMovement : MonoBehaviour
{

public float speed = 10;//速度
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
if (Input.mousePosition.y > Screen.height && Input.mousePosition.y < Screen.height + 100) //判断鼠标位置
{
transform.position += Vector3.forward * (speed * Time.deltaTime);//移动
}
if (Input.mousePosition.y < 0 && Input.mousePosition.y > -100)
{
transform.position += Vector3.back * (speed * Time.deltaTime);
}

if (Input.mousePosition.x > Screen.width && Input.mousePosition.x < Screen.width + 100)
{
transform.position += Vector3.right * (speed * Time.deltaTime);
}

if (Input.mousePosition.x < 0 && Input.mousePosition.x > -100)
{
transform.position += Vector3.left * (speed * Time.deltaTime);
}

 

}
