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

void SWGameMap::onExit(){

    CCLayer::onExit();
}



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()));
}
