[游戏开发]Unity2D_车辆移动方式

添加2D刚体组件

挂载脚本：

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

public class Move : MonoBehaviour
{
    private float horizontal;
    private float vertical;
    
    //私有变量暴露到编辑器
    [SerializeField]
    [Range(0f, 20f)] private float MoveSpeed = 10;//移动速度
    
    [SerializeField]
    [Range(0f, 100f)] private float rotateSpeed = 50f;//转动速度

    Rigidbody2D rigidbody;

    void Start()
    {
        rigidbody = GetComponent<Rigidbody2D>();
    }
    
    void Update()
    {
        float h = Input.GetAxis("Horizontal");//转向
        float v = Input.GetAxis("Vertical");//前后

        Vector3 moveDirection = transform.up*-1f;//获取当前朝向向量

        if (v>=0)
        {
            transform.Rotate(new Vector3(0, 0, -h) * rotateSpeed * Time.deltaTime); //左右旋转
        }
        else
        {
            transform.Rotate(new Vector3(0, 0, h) * rotateSpeed * Time.deltaTime); //倒车时反转控制
            
        }

        if (v!=0)
        {
            rigidbody.AddForce(moveDirection * 10f*v*MoveSpeed);//按键时移动
            
            rigidbody.velocity = Vector2.zero;//消除刚力，否则会一直移动
        }
        else
        {
            rigidbody.velocity = Vector2.zero;//消除刚力，否则会一直移动
        }
    }
}

WS前进后退，AD转向，主要是转向后可以沿着当前朝向的方向移动?
