Cocos2d-x--简单的场景切换及特效

步骤:

1.新建一个Cocos2d-x项目

2.在include中添加SecondScene.h文件,添加代码

3.在source中添加SecondScene.cpp文件,添加代码

4.在HelloWorldScene.cpp中的增加和修改代码



1.新建一个Cocos2d-x项目并运行,保证可以运行起来


2.在include中添加SecondScene.h文件,添加代码

#include "cocos2d.h"
using namespace cocos2d;

class SecondScene : public cocos2d::CCScene
{
public:
	virtual bool init();
	CREATE_FUNC(SecondScene);
	static cocos2d::CCScene* scene();

public:
	CCLayer *m_layer;
};

3.在source中添加SecondScene.cpp文件,添加代码

#include "SecondScene.h"
using namespace cocos2d;

bool SecondScene::init()
{
	bool bRet = false;
	do 
	{
		//实例化精灵
		CCSprite *m_sprite = CCSprite::create("CloseNormal.png");
		CC_BREAK_IF(!m_sprite);

		//设置精灵位置
		m_sprite->setPosition(ccp(100, 100));

		//添加精灵到场景
		this->addChild(m_sprite);
		bRet = true;
	} while (0);
	return bRet;
}

CCScene* SecondScene::scene()
{
	SecondScene *m_secondScene = NULL;
	do 
	{
		//实例化场景
		m_secondScene = SecondScene::create();
		CC_BREAK_IF(!m_secondScene);

		//实例化层
		CCLayer *m_layer = CCLayer::create();
		CC_BREAK_IF(! m_layer);

		//将层添加到场景中
		m_secondScene->addChild(m_layer);
	} while (0);

	return m_secondScene;
}


4.在HelloWorldScene.cpp中的增加和修改代码

加入代码:

#include "SecondScene.h" 

修改HelloWorld::menuCloseCallback(CCObject* pSender)函数

void HelloWorld::menuCloseCallback(CCObject* pSender)
{
    // "close" menu item clicked
    //CCDirector::sharedDirector()->end();
	CCScene *secondScene = SecondScene::scene();
	CCDirector::sharedDirector()->replaceScene(CCTransitionJumpZoom::create(1.0f,secondScene));
}

运行程序,点击右下角的按钮即可实现场景跳转,主要的场景跳转代码是:

CCDirector::sharedDirector()->replaceScene(CCTransitionJumpZoom::create(1.0f,secondScene));

其中CCTransitionJumpZoom::create(1.0f,secondScene)实现特效跳转
