Cocos2D-X笔记(2)场景的切换及特效

在上节的基础上，看看怎么实现场景的切换。

添加一个场景WelcomeScene

WelcomeScene.h

#pragma once
#include "cocos2d.h"

USING_NS_CC;

class WelcomeScene :
public CCLayer
{
public:
WelcomeScene(void);
~WelcomeScene(void);

virtual bool init();

static CCScene* scene();

CREATE_FUNC(WelcomeScene);

void menuOKCallback(CCObject *pSender);
};

WelcomeScene.cpp

#include "WelcomeScene.h"
#include "GameScene.h"

WelcomeScene::WelcomeScene(void){}
WelcomeScene::~WelcomeScene(void){}

CCScene* WelcomeScene::scene()
{
CCScene* scene = CCScene::create();

WelcomeScene* welcomeScene = WelcomeScene::create();
scene->addChild(welcomeScene);

return scene;
}

bool WelcomeScene::init()
{
if(!CCLayer::init())
{
return false;
}

CCSize size = CCDirector::sharedDirector()->getWinSize();

//添加背景
CCSprite* welcomeBg = CCSprite::create("welcome_bg.png");
welcomeBg->setPosition(ccp(size.width / 2, size.height / 2));
this->addChild(welcomeBg, 0);

CCMenuItemImage* okItem = CCMenuItemImage::create(
"ok_normal.png",
"ok_pressed.png",
this,
menu_selector(WelcomeScene::menuOKCallback)
);

CCMenu* menu = CCMenu::create(okItem,NULL);
menu->setAnchorPoint(ccp(1.0f, 0.0f));
menu->setPosition(ccp(size.width - okItem->getContentSize().width,
okItem->getContentSize().height));
this->addChild(menu);

return true;
}

void WelcomeScene::menuOKCallback(CCObject *pSender)
{
CCScene* scene = GameScene::scene();
CCTransitionFadeTR* txScene =  CCTransitionFadeTR::create(1.2, scene);

CCDirector::sharedDirector()->replaceScene(txScene);
}

网上找的特效：
CCTransitionJumpZoom::create(t, s);//跳跃式，本场景先会缩小，然后跳跃进来CCTransitionFade::create(t, s);//淡出淡入，原场景淡出，新场景淡入CCTransitionShrinkGrow::create(t, s);//交错换CCTransitionRotoZoom::create(t, s);//转角换CCTransitionMoveInL::create(t, s);//新场景从左移入覆盖CCTransitionMoveInR::create(t, s);//新场景从右移入覆盖CCTransitionMoveInT::create(t, s);//新场景从上移入覆盖CCTransitionMoveInB::create(t, s);//新场景从下移入覆盖CCTransitionSlideInL::create(t, s);//场景从左移入推出原场景CCTransitionSlideInR::create(t, s);//场景从右移入推出原场景CCTransitionSlideInT::create(t, s);//场景从上移入推出原场景CCTransitionSlideInB::create(t, s);//场景从下移入推出原场景CCTransitionFadeTR::transitionWithDuration(t, s);//向右上波浪CCTransitionFadeBL::transitionWithDuration(t, s);//向左下波浪CCTransitionFadeUp::transitionWithDuration(t, s);//向上百叶窗CCTransitionFadeDown::transitionWithDuration(t, s);//向下百叶窗CCTransitionTurnOffTiles::transitionWithDuration(t, s);//随机小方块CCTransitionSplitRows::transitionWithDuration(t, s);//按行切CCTransitionSplitCols::transitionWithDuration(t, s);//按列切
