cocos2d-x 3.0游戏开发xcode5帅印博客教学 003.[HoldTail]游戏世界以及背景画面
写给大家的前言，在学习cocos2d-x的时候自己走了很多的弯路，也遇到了很多很多问题，不管是简单的还是困难的现在都慢慢的一步一步克服了，其实用cocos2d－x做游戏特别的简单，大家不要被是做游戏吓到了，支持我把游戏开源的原因是因为 eoe上海 的大家的支持。加油，加油，要说明一下的是，写得不好还请大家多多包含哦。相信你们跟着我得博客，一步一步做肯定会成功的。
昨天做了游戏的主场景的开始画面，今天要做的是整个游戏的世界和游戏的滚动的背景
注意由于是在模拟器上门进行所以帧不高，但是如果是在真机上，则是60帧满帧运行
效果图
首先建立背景地图类

地图类建立完成之后，接下来建立游戏世界类
// // SWGameWorld.h // Holdtail // // Created by 帅 印 on 13-12-02. // // #ifndef __Holdtail__SWGameWorld__ #define __Holdtail__SWGameWorld__ #include <iostream> #include "cocos2d.h" //定义属性 typedef enum { tag_player }tagWorld; class SWGameWorld:public cocos2d::Layer{ public: static cocos2d::Scene *scene(); static SWGameWorld *sharedWorld(); private: virtual bool init(); CREATE_FUNC(SWGameWorld); }; #endif /* defined(__Holdtail__SWGameWorld__) */
// // SWGameWorld.cpp // Holdtail // // Created by 帅 印 on 13-12-02. // // #include "SWGameWorld.h" #include "cocos2d.h" #include "SimpleAudioEngine.h" #include "SWGameMap.h" using namespace cocos2d; using namespace CocosDenshion; //声明静态变量 static SWGameWorld *SWGW; SWGameWorld *SWGameWorld::sharedWorld(){ if(SWGW != NULL){ return SWGW; } return NULL; } Scene *SWGameWorld::scene(){ Scene *scene = Scene::create(); SWGameWorld *layer = SWGameWorld::create(); scene->addChild(layer); return scene; } //创建场景 bool SWGameWorld::init(){ if( !Layer::init()){ return false; } SWGW = this; //地图 SWGameMap *map = SWGameMap::createMap("cloudbg.png","cloud04.png","cloud03.png","cloud02.png","cloud01.png","treesbg.png"); addChild(map); return true; }
当这两个类都建立完成后，就可以使用了，点击开始游戏按钮，切换到世界类，背景就可以滚动咯
//各种按钮点击的方法实现 void SWMenu::PlayPressed(Object* pSender){ //实现 CCDirector::getInstance()->replaceScene(CCTransitionFade::create(0.5, SWGameWorld::scene())); }
