[游戏开发]Unity3D:2D角色移动篇：刚体的移动

一、创建精灵并添加刚体和碰撞体

?二、创建PlayerController脚本并编写

?

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

public class PlayerController : MonoBehaviour
{
    //速度
    public int speed;
    //刚体
    Rigidbody2D player;
    //位置
    Vector2 moveX;
    void Start()
    {
        player = this.GetComponent<Rigidbody2D>();
       
    }
   
    private void FixedUpdate()
    { 
            Ider();
            Run();     
    }
    //等待
    private void Ider()
    {
        moveX.x = Input.GetAxisRaw("Horizontal");
       
    }
    //跑步
    private void Run()
    {


        if (moveX.x != 0)
        {
            //人物根据移动方向旋转
            transform.localScale = new Vector3(moveX.x, 1, 1);
            //MovePosition()方法：自身位置+moveX * Time.fixedDeltaTime * speed
            player.MovePosition(player.position + moveX * Time.fixedDeltaTime * speed);
           

        }
    }
    

}

?三、把脚本挂在player上，运行脚本，控制player左右移动
