Cocos2D-x游戏开发之八：事件连续执行:CCMoveBy CCCallFunc CCSequence

接下来让我们继续基础知识的最后一节，将各种事件按照先后顺序连接起来是一件非常重要的事情，这一节我们做一个简单的Demo。

我先执行移动Action然后在移动完成之后再告诉你们我已经到家了。。

任然比较简单，代码如下：

bool HelloWorld::init()

{

bool bRet = false;

do

{

CC_BREAK_IF(! CCLayer::init());

CCMenuItemImage *pCloseItem = CCMenuItemImage::create(

"CloseNormal.png",

"CloseSelected.png",

this,

menu_selector(HelloWorld::menuCloseCallback));

CC_BREAK_IF(! pCloseItem);

pCloseItem->setPosition(ccp(CCDirector::sharedDirector()->getWinSize().width - 20, 20));

CCMenu* pMenu = CCMenu::create(pCloseItem, NULL);

pMenu->setPosition(CCPointZero);

CC_BREAK_IF(! pMenu);

// Add the menu to HelloWorld layer as a child layer.

this->addChild(pMenu, 1);

// 3. Add add a splash screen, show the cocos2d splash image.

CCSprite* pSprite = CCSprite::create("sprite.png");

CC_BREAK_IF(! pSprite);

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

pSprite->setPosition(ccp(0, size.height/2));

this->addChild(pSprite, 0);

CCMoveBy *move= CCMoveBy::create(4.0f,ccp(size.width-50,size.height/4));

CCCallFunc *cal = CCCallFunc::create(this,callfunc_selector(HelloWorld::callfunc));

CCSequence *seo = CCSequence::create(move,cal,NULL);

pSprite->runAction(seo);

bRet = true;

} while (0);

return bRet;

}

void HelloWorld::menuCloseCallback(CCObject* pSender)

{

// "close" menu item clicked

CCDirector::sharedDirector()->end();

}

void HelloWorld::callfunc()

{

CCLabelTTF *label = CCLabelTTF::create("I am Home","Arial",35);

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

label->setPosition(ccp(size.width-200,size.height/2));

this->addChild(label);

CCBlink *blink = CCBlink::create(6.0f,50);

label->runAction(blink);

}
