(学习笔记)设计模式之模版方法

在某个步骤，所有的事物进行步骤相同，只有其中一两个有区别可以用模版方法；

比如去餐馆吃饭，所有人都是点菜，吃东西，结账。只有点餐的过程是有区别的。

public class DM04TempleMethod : MonoBehaviour{    private void Start()    {        Ipeople people = new SouthPeople();        people.Eat();    }}    public abstract class Ipeople{    public void Eat()    {        OrderFood();        EatSomething();        PayBill();    }    protected virtual void OrderFood()//点菜    {            }    private void EatSomething()    {        Debug.Log("吃东西");    }    private void PayBill()    {        Debug.Log("买单");    }}public class NorthPeople:Ipeople{    protected override void OrderFood()    {        Debug.Log("我在点面条");    }}public class SouthPeople:Ipeople{    protected override void OrderFood()    {        Debug.Log("我在点米饭");    }}
