cocos2dx 3.3 魂斗罗初步尝试 游戏层（暂停段时间，以后再写）。。。

//重点且复杂。。。

//控制采用了模拟方向键，长按使用定时器实现//设计的是单点触控，败笔啊（准备以后再改）//移植到安卓下按键会有点问题，windows下正常（不知道为什么）//目前只实现了地图部分地面，主角的动作，碰撞检测//8方向还未实现，敌人也只做了一种，子弹也只做了一种//待实现：敌人的移动，敌人出现时机，子弹的部分完善（子弹的移动速度和随着人物移动子弹的移动）#pragma once#include "cocos2d.h"#include "Def.h"#include "Player.h"#include "Bullt.h"#include "Enemy.h"using namespace std;USING_NS_CC;class GameLayer :public Layer{public: CREATE_FUNC(GameLayer);
