执行效果： |
2 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。
