UML类图: 
(1) AbstractClass（抽象类）：在抽象类中定义了一系列基本操作(PrimitiveOperations)，这些基本操作可以是具体的，也可以是抽象的，每一个基本操作对应算法的一个步骤，在其子类中可以重定义或实现这些步骤。同时，在抽象类中实现了一个模板方法(Template Method)，用于定义一个算法的框架，模板方法不仅可以调用在抽象类中实现的基本方法，也可以调用在抽象类的子类中实现的基本方法，还可以调用其他对象中的方法。 (2) ConcreteClass（具体子类）：它是抽象类的子类，用于实现在父类中声明的抽象基本操作以完成子类特定算法的步骤，也可以覆盖在父类中已经实现的具体基本操作。 原型实现:using System;
using System.Collections.Generic;
using System.Text;
using UnityEngine;
public class DM04TempleMethod:MonoBehaviour
{
void Start()
{
IPeople people = new NorthPeople();
people.Eat();
}
}
public abstract class IPeople
{
public void Eat() //吃东西的方法
{
OrderFoods(); //点单
EatSomething(); //吃
PayBill(); //付账
}
private void OrderFoods()
{
Debug.Log("点单");
}
protected virtual void EatSomething() //吃的虚方法
{
}
private void PayBill()
{
Debug.Log("买单");
}
}
//实现吃的方法
public class NorthPeople : IPeople
{
protected override void EatSomething()
{
Debug.Log("我在吃面条");
}
}
public class SouthPeople : IPeople
{
protected override void EatSomething()
{
Debug.Log("我在吃米饭");
}
}
实例实现: 武器开火(不同武器开火)使用模板方法实现:
public void Fire(Vector3 targetPosition) //在武器抽象类中开火功能
{
//显示枪口特效
PlayMuzzleEffect();
//显示子弹轨迹特效
PlayBulletEffect(targetPosition);
//设置特效显示时间
SetEffetDisplayTime();
//播放声音
PlaySound();
}
protected virtual void PlayMuzzleEffect()
{
mPariticle.Stop();
mPariticle.Play();
mLight.enabled = true;
}
protected abstract void PlayBulletEffect(Vector3 targetPosition);
protected abstract void SetEffetDisplayTime();
protected void DoPlayBulletEffect(float width,Vector3 targetPosition)
{
mLine.enabled = true;
mLine.startWidth = width; mLine.endWidth = width;
mLine.SetPosition(0, mGameObject.transform.position);
mLine.SetPosition(1, targetPosition);
}
protected abstract void PlaySound();
protected void DoPlaySound(string clipName)
{
AudioClip clip = FactoryManager.assetFactory.LoadAudioClip(clipName);
mAudio.clip = clip;
mAudio.Play();
} using System;
using System.Collections.Generic;
using System.Text;
using UnityEngine;
public class WeaponRifle:IWeapon //长枪实现
{
public WeaponRifle(WeaponBaseAttr baseAttr, GameObject gameObject) : base(baseAttr, gameObject) { }
protected override void PlayBulletEffect(Vector3 targetPosition)
{
DoPlayBulletEffect(0.1f, targetPosition);
}
protected override void PlaySound()
{
DoPlaySound("RifleShot");
}
protected override void SetEffetDisplayTime()
{
mEffectDisplayTime = 0.3f;
}
}
using System.Collections.Generic;
using System.Text;
using UnityEngine;
public class WeaponGun:IWeapon //短枪实现
{
public WeaponGun(WeaponBaseAttr baseAttr , GameObject gameObject) : base(baseAttr, gameObject) { }
protected override void PlayBulletEffect(Vector3 targetPosition)
{
DoPlayBulletEffect(0.05f, targetPosition);
}
protected override void PlaySound()
{
DoPlaySound("GunShot");
}
protected override void SetEffetDisplayTime()
{
mEffectDisplayTime = 0.2f;
}
}
