正如木头所说的，这一章将之前学的知识都使用上了

创建主角精灵

1.将类分类存放，创建筛选器，有点像eclipse的包名，不过vs的是虚拟的，没有改变文件路径的。

2.创建实体基类，当游戏中存在多种实体时，我们可以创建一个基类

习惯将所有要引用的头文件放到类的头文件中，

//头文件#ifndef _ENTITY_H_#define _ENTITY_H_#include "cocos2d.h"USING_NS_CC;class Entity : public Node{public:Entity();~Entity();Sprite* getSprite();void bindSprite(Sprite* sprite);private:Sprite* m_sprite;};#endif

#include "Entity.h"Entity::Entity(){m_sprite = NULL;}Entity::~Entity(){}Sprite* Entity::getSprite(){return this->m_sprite;}void Entity::bindSprite(Sprite* sprite){this->m_sprite = sprite;this->addChild(m_sprite);}

//实现了精灵的绑定

3.创建主角类

主角类暂时没有做什么事情。

#ifndef _PLAYER_H_#define _PLAYER_H_#include "cocos2d.h"#include "Entity.h"USING_NS_CC;class Player : public Entity{public:Player();~Player();CREATE_FUNC(Player);virtual bool init();private:};#endif

#include "Player.h"Player::Player(){}Player::~Player(){}bool Player::init(){return true;}

4.创建游戏场景

#ifndef _TOLLGATE_SCENE_H_#define _TOLLGATE_SCENE_H_#include "cocos2d.h"#include "Player.h"USING_NS_CC;class TollgateScene : public Layer{public:static Scene* createScene();//创建场景virtual bool init();//初始化CREATE_FUNC(TollgateScene);//virtual void update(float delta);//定时的操作private:void initBG();//初始化关卡背景private:Sprite* m_bgSprite1;//背景精灵1Sprite* m_bgSprite2;//背景精灵2Player* m_player;//主角};#endif

cpp文件，好吧，我把背景移动的也加进来了

#include "TollgateScene.h"Scene* TollgateScene::createScene(){Scene* scene = Scene::create();scene->addChild(TollgateScene::create());return scene;}bool TollgateScene::init(){if (!Layer::init()){return false;}Size visibleSize = Director::getInstance()->getVisibleSize();Sprite* titleSprite = Sprite::create("title.png");titleSprite->setPosition(Point(visibleSize.width/2,visibleSize.height - 50));this->addChild(titleSprite,2);m_player = Player::create();//创建主角m_player->bindSprite(Sprite::create("sprite.png"));m_player->setPosition(Point(200,visibleSize.height/4));this->addChild(m_player,3);//加入到最前面的initBG();//初始化背景this->scheduleUpdate();//注册定时器return true;}void TollgateScene::initBG(){Size visibileSize = Director::getInstance()->getVisibleSize();m_bgSprite1 = Sprite::create("tollgateBG.jpg");m_bgSprite1->setPosition(visibileSize.width/2,visibileSize.height/2);this->addChild(m_bgSprite1,0);m_bgSprite2 = Sprite::create("tollgateBG.jpg");//将背景往右边平移屏幕个宽度，完全移出屏幕了m_bgSprite2->setPosition(visibileSize.width+visibileSize.width/2,visibileSize.height/2);m_bgSprite2->setFlippedX(true);//水平翻转，是图片衔接看起来更平滑this->addChild(m_bgSprite2,0);}//启动定时器，让背景图片定时刷新，即移动void TollgateScene::update(float delta){log("%f",delta);int pos1 = m_bgSprite1->getPositionX();//获取当前位置,理解为中心点的位置int pos2 = m_bgSprite2->getPositionX();int speed = 1;//速度为1pos1 -= speed;//像左移动1个速度pos2 -= speed;//背景图片的sizeSize mapSize = m_bgSprite1->getContentSize();//当背景图片的中心点移动到-mapSize.width/2的位置时，说明背景图片完全移出了屏幕，//就再次把背景图片放到右边的屏幕外if (pos1<=-mapSize.width/2){pos1 = mapSize.width + mapSize.width/2;}if (pos2<=-mapSize.width/2){pos2 = mapSize.width + mapSize.width/2;}//更新位置m_bgSprite1->setPositionX(pos1);m_bgSprite2->setPositionX(pos2);}

5.修改屏幕大小

背景图片是800x500的规格，所以我们也将窗口设置成800x500的

glview->setFrameSize(800,500);
