设置资源查找路径

默认是Resources下面查找

std::vector<std::string> searchPath;
searchPath.push_back("sd");
//searchPath.push_back("/");
FileUtils::getInstance()->setSearchPaths(searchPath);

如果这样设置那么查找的目录是变成： Resources/sd/

音乐声音

预加载：

SimpleAudioEngine::getInstance()->preloadBackgroundMusic("**.mp3"); 
SimpleAudioEngine::getInstance()->preloadEffect("**.wav");

播放声音：

SimpleAudioEngine::getInstance()->playBackgroundMusic("**.wav");  
SimpleAudioEngine::getInstance()->playBackgroundMusic("**.wav",true);  
SimpleAudioEngine::getInstance()->playEffect("**.mp3",false);

菜单

创建菜单按钮

auto backItem = MenuItemImage::create(
                                           "**.png",//默认图片
                                           "**.png",//选中图片
                                           CC_CALLBACK_1(**::menuBackCallback//按钮点击事件触发回调,this));

开关菜单按钮

MenuItemImage *_trnOn,*_trnOff;
    _trnOn = MenuItemImage::create(  
        "btn_**On.png","btn_**On.png");  
    _trnOff = MenuItemImage::create(  
        "btn_**Off.png","btn_**Off.png");
MenuItemToggle *toggleItem = MenuItemToggle::createWithCallback(
                            CC_CALLBACK_1(**::toggleMenuCallback,this),_turnOn,_turnOff,NULL);
toggleItem->setSelectedindex(1);//设置初始值

创建菜单

auto menu = Menu::create(backItem,toggleItem,**Item,NULL);

加进场景（之前设置显示位置等）//比如backItem->setPosition(Vec2(* *,* *));

this -> addChild( menu );//*->removeFromParent();移除

本地存储

获取值：

UserDefault::getInstance()->getBoolForKey("**")

存储值：

UserDefault::getInstance()->setBoolForKey("**",false);

场景转跳

auto scene = MainScene::createScene();
TransitionScene* reScene = TransitionPageTurn::create(1.0f,scene,true);
Director::getInstance()->replaceScene(reScene);

显示图片

auto sprite = Sprite::create("scene_end.png");
sprite->setPosition(Point(GAME_SCREEN_WIDTH/2,GAME_SCREEN_HEIGHT/2));
this->addChild(sprite);

显示文字

TTFConfig config("yuehei.otf",48);
auto labelscore = Label::createWithTTF(config," 0 ");
labelscore -> setPosition(Point( GAME_SCREEN_WIDTH/2,GAME_SCREEN_HEIGHT/1.4));
this->addChild(labelscore);

交互

添加监听

auto touchListener = EventListenerTouchOneByOne::create();
touchListener->onTouchBegan = CC_CALLBACK_2(GameScene::onTouchBegan,this);
touchListener->onTouchMoved = CC_CALLBACK_2(GameScene::onTouchMoved,this);
_eventdispatcher->addEventListenerWithSceneGraPHPriority(touchListener,this);

获取点击点

auto location = touch->getLocation();

判断点击点是否在某区域
（可以根据点击点获取sprite 也可以根据结束点几点判断左滑右滑）

auto  upRect = Rect(*，*，*，*);
if (upRect.containsPoint(location)) { }

简单动画

staSprite->runAction(Moveto::create(time,posOfDest));//移动位置

staSprite->runAction(Sequence::create(
                                      Moveto::create(time,posOfDest),Moveto::create(time,posOfSrc),NULL));//先后连续移动两次位置

节点位置 position 节点位置 anchorpoint 锚点，默认节点中心，position的位置的参考点，scale缩放的参考点，rotation旋转的参考点
