在场景创建一个Cube,并添加刚体，如图：

编写脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;[RequireComponent(typeof(Rigidbody))]
public class RibRotate : MonoBehaviour
{//private Vector3 mouseStartPosition;private Rigidbody rigidbody;//private bool isMouseDown;private float moveSpeed = 5f;private float rotationSpeed = 10f;// Start is called before the first frame updatevoid Start(){rigidbody = GetComponent<Rigidbody>();        }// Update is called once per framevoid Update(){float vertical = Input.GetAxis("Vertical");float horizontal = Input.GetAxis("Horizontal");if (Input.GetMouseButton(0)){    //鼠标左键控制左右旋转rigidbody.angularVelocity = -transform.up * horizontal * rotationSpeed;}else if(Input.GetMouseButton(1)){//鼠标右键控制上下移动rigidbody.velocity = -transform.forward * vertical * moveSpeed;}//if (Input.GetMouseButtonDown(0))//{//    mouseStartPosition = Input.mousePosition;//    isMouseDown = true;//}//if (Input.GetMouseButtonUp(0))//{//    isMouseDown = false;//}//if (isMouseDown)//{//    // 获取鼠标移动距离和方向，并计算旋转角度//    float mouseX = Input.GetAxis("Mouse X");//    float mouseY = Input.GetAxis("Mouse Y");//    Vector3 rotation = new Vector3(-mouseY, mouseX, 0) * rotationSpeed;//    // 应用旋转//    transform.Rotate(rotation);//}}
}

把脚本添加到Cube中，运行：

如视频所示，效果真的不行，只能单纯上下或左右移动旋转刚体，同时用鼠标控制效果更差。所以使用上面方法纯粹就是玩玩。
