《Flappy Bird》
关于这个游戏骨头不多说了
直接开始学习吧（山寨不好听）
正好前段时间看了几个DEMO拿这个游戏练练手
开搞！
报环境：
vs2013+cocos2dx3.0beta2
首先下载apk，找到资源文件，，裁剪几个图片：
用脚本新建一个空的Cocos2dx项目
新建一个Scene类
#include "cocos2d.h"#include "Obstacle.h"class FlyBirdGame :public cocos2d::Layer{public:static cocos2d::Scene* createScene();virtual bool init();CREATE_FUNC(FlyBirdGame);void initUI();void gameStart(Object* pSender); void update(float time);Obstacle* obstacle;};#include "cocos2d.h"#include "FlyBirdGame.h"#include "resource.h"; USING_NS_CC;Scene* FlyBirdGame::createScene(){auto scene = Scene::create();auto layer = FlyBirdGame::create();scene->addChild(layer);return scene;}bool FlyBirdGame::init(){if (!Layer::init()){return false;}initUI();return true;}initUI里是一些UI初始化方法：// win sizeauto winSize = Director::getInstance()->getVisibleSize();// game bgauto bg = Sprite::create(bird_bg);bg->setPosition(winSize.width / 2, winSize.height / 2);bg->setScale(winSize.width / bg->getContentSize().width, winSize.height / bg->getContentSize().height);this->addChild(bg);// start btnauto startBtn = MenuItemImage::create(bird_start_btn, bird_start_btn_pressed, CC_CALLBACK_1(FlyBirdGame::gameStart, this));auto menu = Menu::create(startBtn, NULL);menu->setTag(100);this->addChild(menu);// heroauto hero = Sprite::create(bird_hero);hero->setPosition(winSize.width / 5, winSize.height*0.8);hero->setVisible(false);hero->setTag(200);this->addChild(hero);
开始游戏按钮绑定的gameStart方法：
void FlyBirdGame::gameStart(Object* pSender){auto btn = this->getChildByTag(100);btn->setVisible(false);auto hero = this->getChildByTag(200); Size win = Director::getInstance()->getWinSize();obstacle->gameStart = true;}隐藏开始按钮，显示小鸟，水管开始移动
还有更新方法：
scheduleUpdate();void FlyBirdGame::update(float time){obstacle->update();}=======================================
水管类：Obstacle.cpp
update方法里判断游戏是游戏是否开始
void Obstacle::update(){if (gameStart == false)return;addCount++;if (addCount == 60){addOne(0);addCount = 0;}for (int i = obstacleList->count() – 1; i >= 0; i–){auto s = (Sprite*)obstacleList->getObjectAtIndex(i);s->setPositionX(s->getPositionX() – 3);if (s->getPositionX() < -s->getContentSize().width / 2){obstacleList->removeObjectAtIndex(i);this->removeChild(s);}}}水管类的更新方法里，每60帧（1秒）添加一对水管
并且遍历水管列表
出边界的化销毁
接下来是addOne方法：添加水管方法：
void Obstacle::addOne(int offsetX){Size size = Director::getInstance()->getWinSize();auto sprite = Sprite::create(bird_obstacle_up);Size spriteSize = sprite->getContentSize();obstacleList->addObject(sprite);this->addChild(sprite);auto sprite2 = Sprite::create(bird_obstacle_down);Size spriteSize2 = sprite->getContentSize();obstacleList->addObject(sprite2);this->addChild(sprite2);// set positonint maxUpY = size.height + spriteSize.height / 4;int minUpY = size.height – spriteSize.height / 4;int y1 = CCRANDOM_0_1()*(maxUpY – minUpY) + minUpY;int maxDownY = spriteSize.height / 4;int minDownY = -spriteSize.height / 4;int y2 = CCRANDOM_0_1()*(maxDownY – minDownY) + minDownY;if (y1 – y2 – spriteSize.height < 160){y2 = y1 – spriteSize.height – 160;}sprite->setPosition(ccp(size.width + spriteSize.width / 2 + offsetX, y1));sprite2->setPosition(ccp(size.width + spriteSize2.width / 2 + offsetX, y2));}这段代码比较凌乱，就是找到水管上下位置的范围
然后随机一下，并且保证上下连个水管有个最小的距离
效果如下：
=============================
此时的游戏还没触摸和碰撞逻辑
马上添加：（刚才抽空玩了把魔方：五阶的我只能搞定一个面，虽然有官方规律但是那样好像比的是记忆力）
听说cocos2dx3.0的事件监听方式改变了
