上篇中实现的是Cocos2d-x提供给我们的动画，这次要实现的动画是自定义的动画。

这次实现的是让一个精灵一直执行我给的图片，从而达到动画的效果，还是截几张图看看。

图片资源来自解压《捕鱼达人》和《魔塔》

一共有18张图片。

       CCTexture2D *pTexture=CCTextureCache::sharedTextureCache()->addImage("hero.png");CCSpriteFrame *frame0=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(0,0,32,32));CCSpriteFrame *frame1=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(32,0,32,32));CCSpriteFrame *frame2=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(64,0,32,32));CCSpriteFrame *frame3=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(96,0,32,32));CCArray  *animFrames=CCArray::create();CC_BREAK_IF(!animFrames);animFrames->addObject(frame0);animFrames->addObject(frame1);animFrames->addObject(frame2);animFrames->addObject(frame3);CCAnimation *animation=CCAnimation::createWithSpriteFrames(animFrames,0.2f);CC_BREAK_IF(!animation);CCSprite *heroSprite0=CCSprite::createWithSpriteFrame(frame0);CC_BREAK_IF(!heroSprite0);heroSprite0->setPosition(ccp(100,100));addChild(heroSprite0,1);CCAnimate *animate=CCAnimate::create(animation);heroSprite0->runAction(CCRepeatForever::create(animate));//一直执行下去

上面的动画是使英雄一直执行走动下去。

还有另外的一种方法来实现自定义动画：

CCAnimation* animation2 = CCAnimation::create(); for(int i=1;i<19;i++){char *tt=new char[3];memset(tt,0,3);std::string s;if(i<10){itoa(i,tt,10);s="fish00"+std::string(tt);}else{itoa(i,tt,10);s="fish0"+std::string(tt);}s=s+".png";CCTexture2D *playerRunTexture = CCTextureCache::sharedTextureCache()->addImage(s.c_str());  animation2->addSpriteFrame(CCSpriteFrame::createWithTexture(playerRunTexture, cocos2d::CCRectMake(0, 0, 100, 100)));   delete []tt;}                  animation2->setDelayPerUnit(0.2f);      CCAnimate* action = CCAnimate::create(animation2);      CCTexture2D *playerRunTexture0 = CCTextureCache::sharedTextureCache()->addImage("fish001.png"); CCSprite *p=CCSprite::createWithSpriteFrame(CCSpriteFrame::createWithTexture(playerRunTexture0, cocos2d::CCRectMake(0, 0, 100, 100)));p->setPosition(ccp(200,200));addChild(p,1);p->runAction(CCRepeatForever::create(action));

代码是如此的简单，我就不多说了。

最后照例贴出init函数的全部代码：

bool HelloWorld::init(){mPercentage=100;    bool bRet = false;    do     {             CC_BREAK_IF(! CCLayer::init());             CCTexture2D *pTexture=CCTextureCache::sharedTextureCache()->addImage("hero.png");CCSpriteFrame *frame0=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(0,0,32,32));CCSpriteFrame *frame1=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(32,0,32,32));CCSpriteFrame *frame2=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(64,0,32,32));CCSpriteFrame *frame3=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(96,0,32,32));CCArray  *animFrames=CCArray::create();CC_BREAK_IF(!animFrames);animFrames->addObject(frame0);animFrames->addObject(frame1);animFrames->addObject(frame2);animFrames->addObject(frame3);CCAnimation *animation=CCAnimation::createWithSpriteFrames(animFrames,0.2f);CC_BREAK_IF(!animation);CCSprite *heroSprite0=CCSprite::createWithSpriteFrame(frame0);CC_BREAK_IF(!heroSprite0);heroSprite0->setPosition(ccp(100,100));addChild(heroSprite0,1);CCAnimate *animate=CCAnimate::create(animation);heroSprite0->runAction(CCRepeatForever::create(animate));//一直执行下去CCActionInterval *en=CCRotateBy::create(5,-360);CCSprite *hua=CCSprite::create("end.png");hua->setPosition(ccp(240,160));addChild(hua,1);hua->runAction(CCRepeatForever::create(en));CCAnimation* animation2 = CCAnimation::create(); for(int i=1;i<19;i++){char *tt=new char[3];memset(tt,0,3);std::string s;if(i<10){itoa(i,tt,10);s="fish00"+std::string(tt);}else{itoa(i,tt,10);s="fish0"+std::string(tt);}s=s+".png";CCTexture2D *playerRunTexture = CCTextureCache::sharedTextureCache()->addImage(s.c_str());  animation2->addSpriteFrame(CCSpriteFrame::createWithTexture(playerRunTexture, cocos2d::CCRectMake(0, 0, 100, 100)));   delete []tt;}                  animation2->setDelayPerUnit(0.2f);      CCAnimate* action = CCAnimate::create(animation2);      CCTexture2D *playerRunTexture0 = CCTextureCache::sharedTextureCache()->addImage("fish001.png"); CCSprite *p=CCSprite::createWithSpriteFrame(CCSpriteFrame::createWithTexture(playerRunTexture0, cocos2d::CCRectMake(0, 0, 100, 100)));p->setPosition(ccp(200,200));addChild(p,1);p->runAction(CCRepeatForever::create(action));        bRet = true;    } while (0);    return bRet;}
