cocos2d-x绘制loading页（帧动画）

bool Loading::init()
{
bool bRet = false;
//Parent class initialization
if ( !CCLayer::init() )
{
return false;
}
do
{
//add background sprite picture;
CCSprite *background=CCSprite::create("facade.png");
CCSize size = background->getContentSize();
// background->setContentSize(CCSizeMake(size.width,size.height));
background->setAnchorPoint(ccp(0,0));
background->setPosition(ccp(0,0));
this->addChild(background);
//add animation
//1创建cache 生成纹理
CCSpriteFrameCache* cache = CCSpriteFrameCache::sharedSpriteFrameCache();
char strPlist[64] = {0};
char strPng[64] = {0};
sprintf(strPlist,"load.plist");
//sprintf(strPng,"fei.pvr.ccz");
sprintf(strPng,"load.png");
cache->addSpriteFramesWithFile(strPlist, strPng);

//创建动画每一帧，从cache里面读取
CCArray *animFrames = new CCArray(5);
char str[264] = {0};
//2截取每一帧
for(int i = 1; i <= 5; i++)
{
sprintf(str, "loader_frame_%d.png", i);//%d为通配符一般为数字，例如（01，02...）
CCSpriteFrame* frame = cache->spriteFrameByName( str );
animFrames->addObject(frame);
}
//4生成动作
CCAnimation* animation = CCAnimation::createWithSpriteFrames(animFrames, 0.4f);
//5初始化并设置Sprite
CCSprite *sprite = CCSprite::create();
sprite->setPosition(ccp(this->getContentSize().width/2, this->getContentSize().height/2-200) );
addChild(sprite);

//6使用animation生成一个动画动作animate
CCAnimate *animate = CCAnimate::actionWithAnimation(animation);
sprite->runAction(animate);//重复播放
bRet = true;
}while(0);
return bRet;
}
