[设计模式]命令模式

在这里插入图片描述

代码如下:

#include <iostream>
#include <queue>
#include <Windows.h>
using namespace std;class HandleClientProtocol
{
public:void addMoney(){cout << "给玩家增加金币" << endl;}void addDiamond(){cout << "给玩家增加钻石" << endl;}void addEquipment(){cout << "给玩家穿装备" << endl;}void addLevel(){cout << "给玩家升级" << endl;}
};class AbstractCommand
{
public:virtual void handle() = 0;
};class AddMoneyCommand :public AbstractCommand
{
public:AddMoneyCommand(HandleClientProtocol* protocol) :protocol(protocol) {}virtual void handle(){this->protocol->addMoney();}HandleClientProtocol *protocol;
};class AddDiamondCommand :public AbstractCommand
{

};class AddEquipmentCommand :public AbstractCommand
{

};class AddLevelCommand :public AbstractCommand
{

};class Serser {public:void addRequest(AbstractCommand *command){commands.push(command);}void startHandle(){while (!commands.empty()){Sleep(2000);AbstractCommand *command = commands.front();command->handle();commands.pop();}}queue<AbstractCommand *> commands;};void test01()
