Cocos2d-x3.3beta0创建动画的3种方式

1、单独载入精灵对象

//First,单独渲染每个精灵帧

    auto sprite = Sprite::create("grossini_dance_01.png");

    sprite->setPosition(Vec2(visibleSize.width/2,visibleSize.height/4*3));

    addChild(sprite);

    auto animation = Animation::create();

    char strName[50] = {0};

    for(int i = 1; i <= 14; i++)

    {

        sprintf(strName, "grossini_dance_%02d.png",i);

        animation->addSpriteFrameWithFile(strName);//将全部的精灵载入到animation

    }

    animation->setDelayPerUnit(3.0f / 14);//3秒内播放14帧动画

    animation->setRestoreOriginalFrame(true);//重头開始播放

    sprite->runAction(RepeatForever::create(Animate::create(animation)));//运行动作

2、一次载入，使用精灵帧

//Second，一次渲染

    auto textTure = Director::getInstance()->getTextureCache()->addImage("dragon_animation.png");

    SpriteFrame* frame0 = SpriteFrame::createWithTexture(textTure, Rect(132*0,132*0,132,200));//截取精灵帧

    SpriteFrame* frame1 = SpriteFrame::createWithTexture(textTure, Rect(132*1,132*0,132,200));

    SpriteFrame* frame2 = SpriteFrame::createWithTexture(textTure, Rect(132*2,132*0,132,200));

    SpriteFrame* frame3 = SpriteFrame::createWithTexture(textTure, Rect(132*3,132*0,132,200));

    SpriteFrame* frame4 = SpriteFrame::createWithTexture(textTure, Rect(132*0,132*1,132,200));

    SpriteFrame* frame5 = SpriteFrame::createWithTexture(textTure, Rect(132*1,132*1,132,200));

    Vector<SpriteFrame*> arr;//载入精灵帧

    arr.pushBack(frame0);

    arr.pushBack(frame1);

    arr.pushBack(frame2);

    arr.pushBack(frame3);

    arr.pushBack(frame4);

    arr.pushBack(frame5);

    auto sp = Sprite::createWithSpriteFrame(frame0);//用第一帧精灵对象。初始化精灵

    sp->setPosition(Vec2(visibleSize.width/2,visibleSize.height/2));

    addChild(sp);

    auto animation1 = Animation::createWithSpriteFrames(arr,0.2f);//运行动作

    sp->runAction(RepeatForever::create(Animate::create(animation1)));

3、使用TexturePacker打包精灵对象。帧载入

PNG格式。Layout的Max Size W和H能够修改。可是尺寸是2的幂。4）Publish sprite sheet，打包。保存地址就是project的Resource就可以。代码例如以下：

//Third,first和second的集合，使用TexturePacker工具，将精灵对象打包

    auto cache = SpriteFrameCache::getInstance();

    cache->addSpriteFramesWithFile("animation.plist");//载入plist文件

    auto sp1 = Sprite::createWithSpriteFrameName("grossini_dance_01.png");//使用第一帧精灵初始化对象，精灵对象的名字与plist中的名字一致

    sp1->setPosition(Vec2(visibleSize.width/2,visibleSize.height/4));

    addChild(sp1);

    Vector<SpriteFrame*> arr1;

    char str[50] = {0};

    for(int i = 1; i <= 14; i++)

    {

        sprintf(str, "grossini_dance_%02d.png",i);//将精灵帧载入

        auto frame = cache->getSpriteFrameByName(str);

        arr1.pushBack(frame);

    }

    //运行动作

    auto animation2 = Animation::createWithSpriteFrames(arr1,0.1f);

    sp1->runAction(RepeatForever::create(Animate::create(animation2)));
