cocos2d-x创建精灵动画方式汇总

1、创建精灵框架缓存，并向其中添加相应的动画文件（plist）,最后，通过动画集缓存生产动画

CCSpriteFrameCache *cache = CCSpriteFrameCache::sharedSpriteFrameCache();

cache->addSpriteFramesWithFile("animations/grossini.plist");

cache->addSpriteFramesWithFile("animations/grossini_gray.plist", "animations/grossini_gray.png");

CCSpriteBatchNode *spritebatch = CCSpriteBatchNode::create("animations/grossini.png");//用于批量生产精灵

CCArray* animFrames = CCArray::createWithCapacity();//动态生成数组，类似于vector

for(int i = ; i < ; i++)

{

    //sprintf的作用是字符串格式化，主要功能是把格式化的数据写入某个字符串中。sprintf(str, “ani_conch_%d.png”, 1)后str的值就变成了：ani_conch_1.png

    sprintf(str, "grossini_blue_%02d.png",i);//两位数字，不够的话，用零补全

    CCSpriteFrame *frame = cache->spriteFrameByName(str);

    animFrames->addObject(frame);

}

animation = CCAnimation::createWithSpriteFrames(animFrames, 0.2f);   //创建动画集，切换时间为0.2s

// Add an animation to the Cache

CCAnimationCache::sharedAnimationCache()->addAnimation(animation, "dance_blue"); // 把此动画集加入动画集缓存中，并命名为dance_blue

CCAnimationCache *animCache = CCAnimationCache::sharedAnimationCache();     //共享动画集缓存

CCAnimation *normal = animCache->animationByName("dance");      //获得动画集缓存

CCAnimate *animN = CCAnimate::create(normal);      //创建动画

另外，CCString * str = CCString::createWithFormat("market_chipsLogo%d.png", idx);也可以实现替换数字的效果。

2、直接传入多个图片文件，生成动画

CCSprite *mainsprite=CCSprite::create("catBody1.png");

CCAnimation *animation=CCAnimation::create();

animation->addSpriteFrameWithFileName("catBody1.png");

animation->addSpriteFrameWithFileName("catBody2-4.png");

animation->addSpriteFrameWithFileName("catBody3.png");

animation->addSpriteFrameWithFileName("catBody2-4.png");

animation->setDelayPerUnit(0.1f);//设置动画的间隔时间

animation->setRestoreOriginalFrame(true);//是否返回第一帧

mainsprite->runAction(CCRepeatForever::create(CCAnimate::create(animation)));

3、直接传入一张大图，包含多个小图，生成动画

CCTexture2D *pTexture=CCTextureCache::sharedTextureCache()->addImage("hero.png");

CCSpriteFrame *frame0=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(,,,));

CCSpriteFrame *frame1=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(,,,));

CCSpriteFrame *frame2=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(,,,));

CCSpriteFrame *frame3=CCSpriteFrame::createWithTexture(pTexture,CCRectMake(,,,));

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);

heroSprite0->runAction(CCRepeatForever::create(animate));
