lambda表达式既要捕获函数内的局部变量，有又捕获全局变量怎么写~~求高手指导啊

Cocos2d-x
#1

这样写传入的tmpLayer 报错了 mainLayer是全局变量，开始这样this->getScheduler()->schedule(&](float dt)，可以引用，但是我想删除fail_2 在回调里面，有不设置tag可以解决的方法么？
源码：
Layout *fail_2 = (Layout *)(cocostudio::GUIReader::getInstance()->widgetFromJsonFile(“bigFishEatSmallFish/fail_2.ExportJson”));
mainLayer->addChild(fail_2);
Layer *tmpLayer = mainLayer;
Layer *tmpThis = this;
this->getScheduler()->schedule(&fail_2 , &tmpLayer ,&tmpThis](float dt){

    Layout *fail_1 = (Layout *)(cocostudio::GUIReader::getInstance()->widgetFromJsonFile("bigFishEatSmallFish/fail_1.ExportJson"));
    tmpLayer->addChild(fail_1);
    tmpLayer->removeChild(fail_2);
    Button *replayability = (Button *)(Helper::seekWidgetByName(fail_1,"replayability"));
    replayability->addTouchEventListener(tmpThis,toucheventselector(GameScene::touchEventFailOrSeccess));
    Button *next = (Button *)(Helper::seekWidgetByName(fail_1,"back"));
    next->addTouchEventListener(tmpThis,toucheventselector(GameScene::touchEventFailOrSeccess));

},this,0,1,3,false,"fail_2");
