unity简单商店模式开发的顾客的移动（三）

接上篇上篇实现了点餐的功能
但是我想要的效果是可以控制每一个顾客去柜台点餐
之后再厨房做出来之后我们顾客被柜台呼叫
然后自己去前台取餐

这篇博客我们实现一下顾客的移动的方法
基于这篇进行修改的父类和子类
还是老规矩再给出demo
在这里插入图片描述
看似简单的一个demo 我们需要考虑几个问题
1.点击之后怎么取消其他顾客的点击
2.如何实现顾客的缓动（插值？）
3.如何实现点击

开发过程

点击容易实现使用射线既方便又不容易出错
之前写的一篇关于射线简单的使用地址
给大家参考

我这里专门写了一个顾客的管理器为了很好的管理顾客


using System.Collections;
using System.Collections.Generic;
using System.Diagnostics.SymbolStore;
using TreeEditor;
using UnityEngine;

public class UserManager : MonoBehaviour
{
    //顾客管理器
    public List<User> UserList;

    private Transform UserGroup;//顾客族群

    public static UserManager Instance;
    private void Awake()
    {
        Instance = this;
    }
    private void Start()
    {
        UserGroup = GameObject.Find("UserGroup").GetComponent<Transform>();
        User[] users = UserGroup.GetComponentsInChildren<User>();

        foreach(var a in users)
        {
            UserList.Add(a);
        }
        //全部顾客通过代码添加到群组中
    }
    /// <summary>
    /// 检查所有的isMe
    /// </summary>
    public void CheakAllisMe(string UserTag)
    {
        foreach(var a in UserList)
        {
            if (UserTag != a.UserTag)
            {
                a.isMe = false;
            }
            else
            {
                a.isMe = true;
            }
        }
    }
}

在这里插入图片描述
为了降低耦合度我大部分通过代码赋值这样在unity里能避免很多没有赋值的问题

之后实现顾客的移动我现在了User（父类）上
我直接把整体代码给大家免得还得返回去看

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.PlayerLoop;
using UnityEngine.UI;

public class User : MonoBehaviour
{
    //此类为所有顾客的父类
    public ChinarDelegate Cd;            //委托对象
    protected Text temporaryText; //临时文本,设置公有静态是为了 方便调用颜色属性，去改变服务员文本颜色


    private Vector3 startpos;
    private Transform TalkFoodPosi;
    protected float timer;
    protected bool ismove;

    public string UserTag;//每个顾客专属标签
    public bool isMe = false;//是不是点击了自己
    private  bool isRun=false;

    private Ray ray;
    private RaycastHit hit;
   

    public virtual void  Start()
    {
       

        startpos = transform.position;

        Cd = GameObject.Find("Shopper").GetComponent<ChinarDelegate>(); //获取对象
        Cd.callNumber += LookScreen;
        TalkFoodPosi = GameObject.Find("talkPosi").transform;
    }

    /// <summary>
    /// 抬头看大屏幕
    /// </summary>
    public virtual  void LookScreen()
    {
        //temporaryText.text = "顾客C看向大屏幕";
        StopCoroutine(ClearText());
        StartCoroutine(ClearText());
    }


    /// <summary>
    /// 清理文本内容
    /// </summary>
    /// <returns></returns>
    protected IEnumerator ClearText()
    {
        yield return new WaitForSeconds(3);
        temporaryText.text = "";
    }

    protected virtual void Update()
    {
        if (ismove)
        {
            timer += Time.deltaTime * 0.5f;
        }
        else
        {
            timer -= Time.deltaTime * 0.5f;
        }
        if (timer > 1f)
        {
            ismove = false;

        }
        if (timer <= 0)
        {
            timer = 0;
        }
        //gameObject.transform.position = Vector3.Lerp(startpos, TalkFoodPosi.position, timer);

        FollowMouse();
    }
    private void FollowMouse()
    {
        if (Input.GetMouseButtonDown(0)&&isMe)
        {
            ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            isRun = Physics.Raycast(ray, out hit, 1000);
        }
       
        if (isRun)
        {
            transform.position = 
                Vector3.MoveTowards(transform.position, 
                new Vector3(hit.point.x,transform.position .y,hit.point .z), 
                Time.deltaTime * 20);
        }
        if (transform.position == hit.point)
        {
            isRun = false;
        }
    }
  
}
