cocos2d是通用游戏引擎，为了保持兼容性与易用性，将动画封装为一个Action。简单的过程就是：使用CCTexture2D生成对应的CCSpriteFrame，然后将CCSpriteFrame添加到CCAnimation中生成动画数据，再用CCAnimation生成CCAnimate（最终的动画动作），最后用CCSprite执行这组动作。相关类的关系如图：

相关代码如下： 

CCSize s = CCDirector::sharedDirector()->getWinSize();        CCTexture2D* texture2D = CCTextureCache::sharedTextureCache()->addImage("animation.png");        CCSpriteFrame* frame0 = CCSpriteFrame::frameWithTexture(texture2D, CCRectMake(32 * 0, 0, 32, 48));        CCSpriteFrame* frame1 = CCSpriteFrame::frameWithTexture(texture2D, CCRectMake(32 * 1, 0, 32, 48));        CCSpriteFrame* frame2 = CCSpriteFrame::frameWithTexture(texture2D, CCRectMake(32 * 2, 0, 32, 48));        CCSpriteFrame* frame3 = CCSpriteFrame::frameWithTexture(texture2D, CCRectMake(32 * 4, 0, 32, 48));        CCArray* animFrames = CCArray::createWithCapacity(4);        animFrames->addObject(frame0);        animFrames->addObject(frame1);        animFrames->addObject(frame2);        animFrames->addObject(frame3);        CCAnimation* animation = CCAnimation::animationWithSpriteFrames(animFrames, 0.2f);        animFrames->release();        CCSprite* sprite = CCSprite::spriteWithSpriteFrame(frame0);        sprite->setPosition(ccp(s.width / 2, s.height / 2));        this->addChild(sprite);        CCAnimate* animate = CCAnimate::actionWithAnimation(animation);        sprite->runAction(CCRepeatForever::actionWithAction(animate));
