游戏角色二维刚体，移动，转身定义

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

public class player : MonoBehaviour {
    private Rigidbody2D myRig;
    private bool faceright;
    // Use this for initialization
    void Start () {
        myRig = GetComponent<Rigidbody2D>();
        faceright = true;
    }
    
    // Update is called once per frame
    void Update () {
        float horizonta = Input.GetAxis("Horizontal");
        moveMent(horizonta);
        flip(horizonta);
    }
    private void moveMent(float horizonta)
    {
        myRig.velocity = new Vector2(horizonta,myRig.velocity.y);
    }
    private void flip(float horizonta)
    {
        if(horizonta>0 && !faceright || horizonta<0 && faceright)
        {
            faceright = !faceright;
            Vector3 theScale = transform.localScale;
            theScale.x *= -1;
            transform.localScale = theScale;
        }

由于测试出现游戏角色自动后退和弹道无法跟随角色移动的bug，暂在修复当中，博客也是赶工出来的。所以分享的内容有限，望老师见谅。
