cocos2dx 3.x 图层点击鼠标事件的屏蔽

场景：界面添加一个弹出层，阻止弹出层下面的鼠标事件响应

auto sprite2 = Sprite::create("HelloWorld.png");  // sprite2为弹出层
sprite2->setPosition(Vec2(closeItem->getPositionX(),closeItem->getPositionY()));
this->addChild(sprite2);

//给弹出层添加事件

auto callback = [](Touch * ,Event *) {
        return true;
 };
 auto listener = EventListenerTouchOneByOne::create();
 listener->onTouchBegan = callback;
 listener->setSwallowTouches(true);
 _eventDispatcher->addEventListenerWithSceneGraphPriority(listener,sprite2);
