cocos2d-x基础知识（三） 场景切换
首先讲场景之间的切换吧：从一个场景切换到另一个场景，首先要新建一个cpp文件和.h文件 ，例如你要从HelloWorld场景切换到NewGame场景新建一个NewGame.cpp 和NewGame.h文件新建成功后，是两个空文件，其中的代码可以按照HelloWorld.cpp和HelloWorld.h文件写。如果你懒得写就直接copy吧。然后把其中的该修改的地方修改了。这样就创建了两个场景了。那么接下来该如何实现切换呢 ？在HelloWorld.h里面新定义一个函数：例如：virtual void trans(CCObject *pSender)在HelloWorld.cpp里面去实现这个函数（场景的切换）void HelloWorld::trans(CCObject *pSender){ CCScene *s = CCScene::node(); NewGame *layer = NewGame::node(); s->addChild(layer); CCDirector::sharedDirector()->replaceScene(CCTransitionPageTurn::transitionWithDuration(1, s, true));//这里我是实现的翻页效果，还有很多的其他效果，大家可以去尝试，其他的效果我将列在下面}然后就是如何调用这个函数呢 ？其实很简单呢！例如你建了一个菜单选项：CCMenuItemImage *pLastMenu = CCMenuItemImage::itemFromNormalImage("last.png","last1.png",this, menu_selector(NewGame::trans));//这个就是调用了这个函数，我这里是用图片做的菜单选项，你也可以用字符串做选项，大同小异。 *********************************场景的切换效果*********************************** CCTransitionJumpZoom::transitionWithDuration(t, s);//跳跃式，本场景先会缩小，然后跳跃进来CCTransitionFade::transitionWithDuration(t, s);//淡出淡入，原场景淡出，新场景淡入CCTransitionFade::transitionWithDuration(t, s, ccWHITE);//如果上一个的函数，带3个参数，则第三个参数就是淡出淡入的颜色 CCTransitionFlipX::transitionWithDuration(t, s, kOrientationLeftOver);//x轴左翻 CCTransitionFlipX::transitionWithDuration(t, s, kOrientationRightOver);//x轴右翻CCTransitionFlipY::transitionWithDuration(t, s, kOrientationUpOver);//y轴上翻CCTransitionFlipY::transitionWithDuration(t, s, kOrientationDownOver);//y轴下翻 CCTransitionFlipAngular::transitionWithDuration(t, s, kOrientationLeftOver);//有角度转的左翻 CCTransitionFlipAngular::transitionWithDuration(t, s, kOrientationRightOver);//有角度转的右翻CCTransitionZoomFlipX::transitionWithDuration(t, s, kOrientationLeftOver);//带缩放效果x轴左翻CCTransitionZoomFlipX::transitionWithDuration(t, s, kOrientationRightOver);//带缩放效果x轴右翻 CCTransitionZoomFlipY::transitionWithDuration(t, s, kOrientationUpOver);//带缩放效果y轴上翻CCTransitionZoomFlipY::transitionWithDuration(t, s, kOrientationDownOver);//带缩放效果y轴下翻CCTransitionZoomFlipAngular::transitionWithDuration(t, s, kOrientationLeftOver);//带缩放效果/有角度转的左翻CCTransitionZoomFlipAngular::transitionWithDuration(t, s, kOrientationRightOver);//带缩放效果有角度转的右翻CCTransitionShrinkGrow::transitionWithDuration(t, s);//交错换CCTransitionRotoZoom::transitionWithDuration(t, s);//转角换CCTransitionMoveInL::transitionWithDuration(t, s);//新场景从左移入覆盖CCTransitionMoveInR::transitionWithDuration(t, s);//新场景从右移入覆盖CCTransitionMoveInT::transitionWithDuration(t, s);//新场景从上移入覆盖 CCTransitionMoveInB::transitionWithDuration(t, s);//新场景从下移入覆盖CCTransitionSlideInL::transitionWithDuration(t, s);//场景从左移入推出原场景 CCTransitionSlideInR::transitionWithDuration(t, s);//场景从右移入推出原场景 CCTransitionSlideInT::transitionWithDuration(t, s);//场景从上移入推出原场景CCTransitionSlideInB::transitionWithDuration(t, s);//场景从下移入推出原场景以下三个需要检测opengl版本是否支持CCConfiguration::sharedConfiguration()->getGlesVersion() setDepthTest(true); CCTransitionPageTurn::transitionWithDuration(t, s, false);//翻页，前翻 CCTransitionPageTurn::transitionWithDuration(t, s, true);//翻页，后翻CCTransitionFadeTR::transitionWithDuration(t, s);//向右上波浪CCTransitionFadeBL::transitionWithDuration(t, s);//向左下波浪CCTransitionFadeUp::transitionWithDuration(t, s);//向上百叶窗CCTransitionFadeDown::transitionWithDuration(t, s);//向下百叶窗CCTransitionTurnOffTiles::transitionWithDuration(t, s);//随机小方块 CCTransitionSplitRows::transitionWithDuration(t, s);//按行切 CCTransitionSplitCols::transitionWithDuration(t, s);//按列切
