在 Unity Cardboard VR 中移动鼠标

Question

我想通过推动鼠标在 Cardboard VR 环境中移动相机，但我不知道如何使其工作。有什么想法吗？

下面是移动相机的简单代码片段。

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

public class MouseMove : MonoBehaviour
{
    public Transform cam;
    protected Vector3 left;
    protected Vector3 forward;
    public float scalemove;
    // Start is called before the first frame update
    void Start()
    {
        left = new Vector3(-1, 0, 0);
        forward = new Vector3(0, 0, 1);
        left = left * scalemove;
        forward = forward * scalemove;
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetAxis("Mouse X") < 0)
        {
            cam.Translate(left * Time.deltaTime);
            //Code for action on mouse moving left
            print("Mouse moved left");
        }
        if (Input.GetAxis("Mouse X") > 0)
        {
            cam.Translate(-left * Time.deltaTime);
            //Code for action on mouse moving right
            print("Mouse moved right");
        }
        if (Input.GetAxis("Mouse Y") < 0)
        {
            cam.Translate(-forward * Time.deltaTime);
            //Code for action on mouse moving left
            print("Mouse moved down");
        }
        if (Input.GetAxis("Mouse Y") > 0)
        {
            cam.Translate(forward * Time.deltaTime);
            //Code for action on mouse moving right
            print("Mouse moved up");
        }
    }
}

我在Windows10上使用Unity2019。

谢谢你的建议。

只需给相机一个空的父级，使用鼠标更改父级的位置，代码就可以运行。最好的！
