本文介绍如何在Cocos2d-x中实现动画效果，包括图片加载、纹理创建、帧制作及动画播放等关键步骤，并展示了具体实现代码。

大体思想：

动画效果的使用：

根据图片创建纹理--》根据纹理创建帧，将帧放入到类似List的对象中anim，将

Cpp代码

CCAnimation *animation=CCAnimation::animationWithFrames(anim,0.04f);
CCAnimate *animate = CCAnimate::actionWithAnimation(animation, false);

CCAnimation *animation=CCAnimation::animationWithFrames(anim,0.04f);
CCAnimate *animate = CCAnimate::actionWithAnimation(animation, false);

用第一帧创建CCSprite，

最后精灵runAction

如果要执行多个动画，可以runAction(CCSequence::actions(...));

先将图片异步加载到缓存，异步加载看cocos2d-x源码就是多线程加载，用的pthread，以后使用图片就会更快，这一步一般都是游戏开始的时候用进度条来显示

Cpp代码

CCTextureCache::sharedTextureCache()->addImageAsync(garden_petal1,this,callfuncO_selector(Garden::loadingCallBack));
//CCTexture2D *texture1=CCTextureCache::sharedTextureCache()->addImage(garden_petal1);
CCTextureCache::sharedTextureCache()->addImageAsync(garden_petal2,this,callfuncO_selector(Garden::loadingCallBack));

CCTextureCache::sharedTextureCache()->addImageAsync(garden_petal1,this,callfuncO_selector(Garden::loadingCallBack));
	//CCTexture2D *texture1=CCTextureCache::sharedTextureCache()->addImage(garden_petal1);
	CCTextureCache::sharedTextureCache()->addImageAsync(garden_petal2,this,callfuncO_selector(Garden::loadingCallBack));

在回调函数中处理进度条的显示

代码：

Java代码

//创建纹理
CCTexture2D *texture1=CCTextureCache::sharedTextureCache()->addImage(garden_petal1);
CCTexture2D *texture2=CCTextureCache::sharedTextureCache()->addImage(garden_petal2);
CCTexture2D *texture3=CCTextureCache::sharedTextureCache()->addImage(garden_petal3);
CCTexture2D *texture4=CCTextureCache::sharedTextureCache()->addImage(garden_petal4);
CCTexture2D *texture5=CCTextureCache::sharedTextureCache()->addImage(garden_petal5);
CCTexture2D *texture6=CCTextureCache::sharedTextureCache()->addImage(garden_petal6);
CCTexture2D *texture7=CCTextureCache::sharedTextureCache()->addImage(garden_petal7);
CCTexture2D *texture8=CCTextureCache::sharedTextureCache()->addImage(garden_petal8);
CCTexture2D *texture9=CCTextureCache::sharedTextureCache()->addImage(garden_petal9);
CCTexture2D *texture10=CCTextureCache::sharedTextureCache()->addImage(garden_petal10);
CCTexture2D *texture11=CCTextureCache::sharedTextureCache()->addImage(garden_petal11);
CCTexture2D *texture12=CCTextureCache::sharedTextureCache()->addImage(garden_petal12);
//用纹理创建帧
CCSpriteFrame *frame1 = CCSpriteFrame::frameWithTexture(texture1,CCRectMake(100,100,600,870));
CCSpriteFrame *frame2 = CCSpriteFrame::frameWithTexture(texture2,CCRectMake(100,100,600,870));
CCSpriteFrame *frame3 = CCSpriteFrame::frameWithTexture(texture3,CCRectMake(100,100,600,870));
CCSpriteFrame *frame4 = CCSpriteFrame::frameWithTexture(texture4,CCRectMake(100,100,600,870));
CCSpriteFrame *frame5 = CCSpriteFrame::frameWithTexture(texture5,CCRectMake(100,100,600,870));
CCSpriteFrame *frame6 = CCSpriteFrame::frameWithTexture(texture6,CCRectMake(100,100,600,870));
CCSpriteFrame *frame7 = CCSpriteFrame::frameWithTexture(texture7,CCRectMake(100,100,600,870));
CCSpriteFrame *frame8 = CCSpriteFrame::frameWithTexture(texture8,CCRectMake(100,100,600,870));
CCSpriteFrame *frame9 = CCSpriteFrame::frameWithTexture(texture9,CCRectMake(100,100,600,870));
CCSpriteFrame *frame10 = CCSpriteFrame::frameWithTexture(texture10,CCRectMake(100,100,600,870));
CCSpriteFrame *frame11 = CCSpriteFrame::frameWithTexture(texture11,CCRectMake(100,100,600,870));
CCSpriteFrame *frame12 = CCSpriteFrame::frameWithTexture(texture12,CCRectMake(100,100,600,870));
//添加到类似List的对象中
CCMutableArray<CCSpriteFrame*>* anim=new CCMutableArray<CCSpriteFrame*>(12);
anim->addObject(frame1);
anim->addObject(frame2);
anim->addObject(frame3);
anim->addObject(frame4);
anim->addObject(frame5);
anim->addObject(frame6);
anim->addObject(frame7);
anim->addObject(frame8);
anim->addObject(frame9);
anim->addObject(frame10);
anim->addObject(frame11);
anim->addObject(frame12);
//最用精灵运行动画
CCAnimation *animation=CCAnimation::animationWithFrames(anim,0.4f);
CCAnimate *animate = CCAnimate::actionWithAnimation(animation, false);
CCSprite* txs=CCSprite::spriteWithSpriteFrame(frame1);
txs->setPosition(ccp(100,100));
this->addChild(txs,1);
txs->runAction(animate);
