在Unity中，使用键盘ADWS键控制物体移动，通过鼠标左键控制物体旋转，鼠标中键控制物体缩放是再常见不过的方法。

方法如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class MoveController : MonoBehaviour
{float moveSpeed = 10f;float rotateSpeed = 1000f;// Start is called before the first frame updatevoid Start(){}// Update is called once per framevoid Update(){//获取横轴参数float Horizontal = Input.GetAxis("Horizontal");//获取垂直参数float Vertical = Input.GetAxis("Vertical");        //键盘ADWS键控制物体移动。//通过乘于Time.deltaTime，就可以让物体以每秒moveSpeed单位的速度向前移动transform.Translate(new Vector3(Horizontal * Time.deltaTime * moveSpeed, 0, Vertical * Time.deltaTime * moveSpeed)); //左键鼠标点击状态下移动鼠标旋转if(Input.GetMouseButton(0)){//通过获取鼠标XY轴移动数值控制物体旋转transform.Rotate(new Vector3(Input.GetAxis("Mouse X") * Time.deltaTime * rotateSpeed, Input.GetAxis("Mouse Y") * Time.deltaTime * rotateSpeed));}//通过获取鼠标中键滑动值控制物体缩放transform.localScale += Vector3.one * Input.GetAxis("Mouse ScrollWheel");}
}

 效果如下：Unity 通过键盘鼠标控制物体移动、旋转、缩放_哔哩哔哩_bilibili
