加入场景切换效果

供场景切换的类：

CCTransitionJumpZoom CCTransitionProgressRadialCCW CCTransitionProgressRadialCW CCTransitionProgressHorizontal CCTransitionProgressVertical CCTransitionProgressInOut CCTransitionProgressOutIn CCTransitionCrossFade CCTransitionFadeTR CCTransitionFadeBL CCTransitionFadeUp CCTransitionFadeDown CCTransitionTurnOffTiles CCTransitionSplitRows CCTransitionSplitCols CCTransitionFade CCTransitionShrinkGrow CCTransitionRotoZoom CCTransitionMoveInL CCTransitionMoveInR CCTransitionMoveInT CCTransitionMoveInB CCTransitionSlideInL CCTransitionSlideInR CCTransitionSlideInT CCTransitionSlideInB

场景切换案例：

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。
