cocos2dx3.5 interval 中看两个lambda替换menu_selector,schedule_selector

概述_time0 = _time1 = _time2 = _time3 = _time4 = 0.0f;     auto s = Director::getInstance()->getWinSize();     // sun     auto sun = ParticleSun::create();     sun->setTexture(Director::getInstance()->get _time0 = _time1 = _time2 = _time3 = _time4 = 0.0f;
