cocos2d-x的初步学习十四之坦克大战一

以后的篇幅中，我们来实现2dx版的坦克大战。。好了，我们一步步来实现，OK，我们先实现一个开始游戏这样的一个界面，然后切换到我们的游戏场景，下面直接上代码：

CCSprite *logoSprite=CCSprite::create("BattleCity.png");            logoSprite->setPosition(ccp(wSize.width/2, wSize.height/2+100));        logoSprite->setScale(2.0f);    this->addChild(logoSprite, 1);            //创建菜单    CCMenuItemFont *startItem=CCMenuItemFont::create("开始游戏", this,menu_selector(HelloWorld::startGame));        startItem->setPosition(ccp(wSize.width/2, wSize.height/2-100));    startItem->setFontSizeObj(55);    startItem->setFontNameObj("Georgia-Bold");        CCMenu *pMenu = CCMenu::create(startItem, NULL);        pMenu->setPosition(CCPointZero);        this->addChild(pMenu, 1);

OK，就这么简单，看下效果图：

～～～～～OK，下面我们新建另一个场景类，叫GameScene，然后我们点击开始菜单，进行场景切换：

void HelloWorld::startGame(){    //场景转换    CCScene *pScene = GameLayer::scene();        //跳跃式动画    CCDirector::sharedDirector()->replaceScene(CCTransitionJumpZoom::create(5.0f, pScene));    //其他的一些特效    //    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() <= GLES_VER_1_0如果为真则为不支持//    CCTransitionCrossFade::transitionWithDuration(t,s);//淡出淡入交叉，同时进行//    CCTransitionRadialCCW::transitionWithDuration(t,s);//顺时针切入//    CCTransitionRadialCW::transitionWithDuration(t,s);//逆时针切入//    以下两个需要先设置摄像机，使用CCDirector::sharedDirector()->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            }

OK，切换到另一个场景
