Unity 控制刚体的移动与旋转的方法

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 update
    void Start()
    {
        rigidbody = GetComponent();        
    }

    // Update is called once per frame
    void 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:

Unity鼠标控制刚体移动旋转(实际效果不好,纯粹用来玩玩)

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。
