cocos2dx 开发成长之路 002

在多个layer的情况下，为了避免触摸事件穿透，我们要把触摸事件截取在当前层，具体做法如下

auto listener = EventListenerTouchOneByOne::create();

listener->setSwallowTouches(true);

listener->onTouchBegan = CC_CALLBACK_2(MyLayer::onTouchBegan, this);

_eventDispatcher->addEventListenerWithSceneGraphPriority(listener, this);

bool MyLayer::onTouchBegan(Touch *pTouch, Event *pEvent)

{

return true;

}
