此篇博客介绍了如何使用Unity中的Input类来实现游戏视角的响应式控制，包括通过滚轮调整相机缩放、Alt+左键进行旋转和鼠标点击移动。详细展示了Camera_Scale、Camera_Rotate和Camera_Move函数的实现细节。

void Update()
{
    float scrollWheel = Input.GetAxis("Mouse ScrollWheel");
    if(scrollWheel != 0)
    {
        Camera_Scale(scrollWheel);
    }
    else if(Input.GetKeyDown(KeyCode.LeftAlt))//按下Alt键
    {
        if(Input.GetMouseButton(0))
        {
            Camera_Rotate(); 
        }
    }
    else if(Input.GetMouseButton(2))
    {
        Camera_Move();
    }
}
private void Camera_Scale(float scrollWheel)
{
    scrollWheel = scrollWheel * Time.DeltaTime * 500;
    transform.Translate(Vector3.forward * wheel);
}
private void Camera_Rotate()
{
    float mouseX = Input.GetAxis("Mouse X");
    float mouseY = Input.GetAxis("Mouse Y");
    transform.RotateAround(transform.position, Vector3.up, mouseX * 5);
    transform.RotateAround(transform.position, transform.right, -mouseY * 5);
}
private void Camera_Move()
{
    float mouseX = Input.GetAxis("Mouse X");
    float mouseY = Input.GetAxis("Mouse Y");
    transform.Translate(Vector3.left * mouseX);
    transform.Translate(Vector3.up * mouseY * -1);
}
