小鸟一直在扑翅膀的代码块：

auto sprite = Sprite::create();Animation *animation = Animation::create();animation->addSpriteFrameWithFileName("bird_blue_1.png");animation->addSpriteFrameWithFileName("bird_blue_2.png");animation->addSpriteFrameWithFileName("bird_blue_0.png");animation->setLoops(-1);animation->setDelayPerUnit(0.5/3.0);animation->setRestoreOriginalFrame(true);Animate *animate = Animate::create(animation);sprite->runAction(RepeatForever::create(animate));
