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：
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以下操作
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);
}
//当场景切换彻底完成之后执行的动作。
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。
