cocos2d-x 帧动画的三种实现

  //获取屏幕大小
    Size visibleSize = Director::getInstance()->getVisibleSize();
    //auto size = Director::getInstance()->getWinSize();
 
    //帧动画的创建

    //方式一，通过多张图片来创建
    auto sprite1 = Sprite::create("grossini_dance_05.png");
    sprite1->setPosition(Vec2(visibleSize.width*0.3,visibleSize.height/2));
    this->addChild(sprite1);
     
    //创建帧动画序列，名词形式
    auto animation = Animation::create();
    for (int i=5; i<11; i++)
    {
        char szName[100] = {0};
        sprintf(szName,"grossini_dance_%02d.png",i);
        animation->addSpriteFrameWithFile(szName);
    }
    //设置帧动画属性
    animation->setDelayPerUnit(2.0f / 6);      //每一帧停留的时间，2秒时间完成6幅图片显示，切记要写成2.0f形式！
    animation->setRestoreOriginalFrame(true);       //播放完后回到第一帧
     
    auto animate = Animate::create(animation);
    sprite1->runAction(RepeatForever::create(animate));
     
     
    //方式二，通过一张集合的图片来创建
    //创建2D纹理
    auto texture = Director::getInstance()->getTextureCache()->addImage("dragon_animation.png");
    //建立图片帧
    auto frame0 = SpriteFrame::createWithTexture(texture,Rect(132*0,132*0,132,132));
    auto frame1 = SpriteFrame::createWithTexture(texture,Rect(132*1,132));
    auto frame2 = SpriteFrame::createWithTexture(texture,Rect(132*2,132));
    auto frame3 = SpriteFrame::createWithTexture(texture,Rect(132*3,132));
    auto frame4 = SpriteFrame::createWithTexture(texture,132*1,132));
    auto frame5 = SpriteFrame::createWithTexture(texture,132));
     
    auto sprite2 = Sprite::createWithSpriteFrame(frame0);
    sprite2->setPosition(Vec2(visibleSize.width/2,visibleSize.height/2));
    this->addChild(sprite2);
     
    //保存图片帧
    //Vector<cocos2d::AnimationFrame *> array;
    Vector<cocos2d::SpriteFrame *> array;
    array.pushBack(frame0);
    array.pushBack(frame1);
    array.pushBack(frame2);
    array.pushBack(frame3);
    array.pushBack(frame4);
    array.pushBack(frame5);
     
    auto animation2 = Animation::createWithSpriteFrames(array,0.2f);   //此处createWithSpriteFrames()函数确实每帧间隔时间参数，需自行加上去！！！
    sprite2->runAction(RepeatForever::create(Animate::create(animation2)));
     
     
    //方式三,通过.plist 文件来创建
    auto cache = SpriteFrameCache::getInstance();
    cache->addSpriteFramesWithFile("animate.plist");
     
    auto sprite3 = Sprite::createWithSpriteFrameName("grossini_dance_05.png");
    sprite3->setPosition(Vec2(visibleSize.width*0.7,visibleSize.height/2));
    this->addChild(sprite3);
     
    Vector<cocos2d::SpriteFrame *> arr;
    char str[100] = {0};
    for (int i=1; i<15; i++)
    {
        sprintf(str,i);
        auto frame_2 = cache->SpriteFrameCache::getInstance()->getSpriteFrameByName(str);   //3.2版本有改变
        arr.pushBack(frame_2);
    }
     
    auto animation3 = Animation::createWithSpriteFrames(arr,0.2f);     //此处也不要忘记加上时间间隔参数
    sprite3->runAction(RepeatForever::create(Animate::create(animation3)));
