}

运行效果：

2有时候我们想等场景切换彻底完成之后再让动画播放，这时候需要做重写以下代码：

voidonEnter();

voidonEnterTransitionDidFinish();

案例：

#include"T14Animation.h"

#include"AppMacros.h"

CCScene *T14Animation::scene()

{

CCScene *scene =CCScene::create();

T14Animation *layer =T14Animation::create();

scene->addChild(layer);

returnscene;

}

boolT14Animation::init()

{

TBack::init();

returntrue;

}

//在进入场景的时候做以下操作

voidT14Animation::onEnter()

{

TBack::onEnter();

//以图片的方式创建一个精灵

spr =CCSprite::create("animation/p_2_01.png");

//设置精灵的显示位置

spr->setPosition(ccp(winSize.width / 2, winSize.height / 2));

addChild(spr);

}

//当场景切换彻底完成之后执行的动作。

voidT14Animation::onEnterTransitionDidFinish()

{

TBack::onEnterTransitionDidFinish();

//plist中是图片信息

CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("animation/plant.plist");

//创建动画

CCAnimation *animation =CCAnimation::create();

//这个用于存储图片的名字

char nameBuf[100];

for (inti = 0;i < 8;i++)

{

memset(nameBuf, 0, sizeof(nameBuf));

sprintf(nameBuf,"p_2_0%d.png",i + 1);

animation->addSpriteFrame(CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(nameBuf));

}

//设置每次动画执行的时候的延时

animation->setDelayPerUnit(0.1f);

//这只循环两次

animation->setLoops(2);

CCAnimate *animate =CCAnimate::create(animation);

spr->runAction(animate);

}

上面案例在场景彻底切换完成之后新场景中的动画等效果才执行。
