有时候我们想等场景切换彻底完毕之后再让动画播放，这时候须要做重写下面代码：

void
onEnter();

void
onEnterTransitionDidFinish();

案例：

#include
"T14Animation.h"

#include
"AppMacros.h"

CCScene *T14Animation::scene()

{

CCScene *
scene =
CCScene::create();

T14Animation *
layer =
T14Animation::create();

scene->addChild(layer);

return
scene;

}

bool
T14Animation::init()

{

TBack::init();

return
true;

}

//在进入场景的时候做下面操作

void
T14Animation::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);

}

//当场景切换彻底完毕之后运行的动作。

void
T14Animation::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 (int
i = 0;
i < 8;
i++)

{

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

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

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

}

//设置每次动画运行的时候的延时

animation->setDelayPerUnit(0.1f);

//这仅仅循环两次

animation->setLoops(2);

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

spr->runAction(animate);

}

上面案例在场景彻底切换完毕之后新场景中的动画等效果才运行。
