Unity中外观设计模式的Demo

在Unity新建一个脚本，在这里我取名为DPFacade，并复制以下的代码:

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

/// <summary>
/// 外观模式的内容(上下级之间的调用)
/// </summary>
public class DPFacade : MonoBehaviour
{
    
    
    void Start()
    {
    
    
        Principal pc = new Principal();
        pc.OrderTeacherToDoTask();
    }
}

/// <summary>
/// 上层管理
/// </summary>
public class Principal
{
    
    
    private Teacher teacher = new Teacher();
    /// <summary>
    /// 校长给老师发消息
    /// </summary>
    public void OrderTeacherToDoTask()
    {
    
    
        teacher.OrderStudentsToSummary();
    }
}

/// <summary>
/// 外观角色
/// </summary>
public class Teacher
{
    
    
    private Monitor monitor = new Monitor();
    private LeagueSecretary leagueSecretary = new LeagueSecretary();
    /// <summary>
    /// 老师给班上学生发消息
    /// </summary>
    public void OrderStudentsToSummary()
    {
    
    
        monitor.WriteSummary();
        leagueSecretary.WriteSummary();
    }
}

/// <summary>
/// 班长学生类
/// </summary>
public class Monitor
{
    
    
    public void WriteSummary()
    {
    
    
        Debug.Log("班长的总结");
    }
}

/// <summary>
/// 团支书学生类
/// </summary>
public class LeagueSecretary
{
    
    
    public void WriteSummary()
    {
    
    
        Debug.Log("团支书的总结");
    }
}
