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

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

/// <summary>
/// 中介者模式(同一层级之间相互调用)
/// </summary>
public class DBMediator : MonoBehaviour
{
    
    
    void Start()
    {
    
    
        Matchmaker man = new Man(50,100000000,100000,0);
        Matchmaker woman = new Women(20,0,0,0);
        WomanMatchmakerMediator womanMatchmakerMediator = new WomanMatchmakerMediator(man,woman);

        womanMatchmakerMediator.OfferManInformationToWoman();
        womanMatchmakerMediator.OfferWomanInformationToMan();
        Debug.Log("男方目前的好感度是:"+man.m_favor);
        Debug.Log("女方目前的好感度是:"+woman.m_favor);
    }
}

/// <summary>
/// 同级之间相互调用的中介者
/// </summary>
public class WomanMatchmakerMediator
{
    
    
    private Matchmaker m_man;
    private Matchmaker m_woman;

    public WomanMatchmakerMediator(Matchmaker man,Matchmaker woman)
    {
    
    
        m_man = man;
        m_woman = woman;
    }

    public void OfferWomanInformationToMan()
    {
    
    
        m_man.m_favor += -m_woman.m_age + m_woman.m_familyBG + m_woman.m_money;
    }

    public void OfferManInformationToWoman()
    {
    
    
        m_woman.m_favor += -m_man.m_age + m_man.m_familyBG + m_man.m_money;
    }
}

/// <summary>
/// 相亲者都需要继承的抽象基类(共有的属性以及方法，以及各自必须要单独实现的抽象方法)
/// </summary>
public abstract class Matchmaker
{
    
    
    public int m_age;
    public int m_money;
    public int m_familyBG;
    public int m_favor;

    public Matchmaker(int age, int money, int familyBG, int favor)
    {
    
    
        m_age = age;
        m_money = money;
        m_familyBG = familyBG;
        m_favor = favor;
    }
}

/// <summary>
/// 男性相亲者
/// </summary>
public class Man : Matchmaker
{
    
    
    public Man(int age, int money, int familyBG, int favor):base(age,money,familyBG,favor)
    {
    
    
    }
}

/// <summary>
/// 女性相亲者
/// </summary>
public class Women : Matchmaker
{
    
    
    public Women(int age, int money, int familyBG, int favor) : base(age, money, familyBG, favor)
    {
    
    
    }
}
