auto listenerkeyPad = EventListenerKeyboard::create();
listenerkeyPad->onKeyReleased = CC_CALLBACK_2(GameLayer::onKeyReleased, this);
_eventDispatcher->addEventListenerWithSceneGraphPriority(listenerkeyPad, this);
void GameLayer::onKeyReleased(EventKeyboard::KeyCode keycode, cocos2d::Event *event)
{
if (keycode == EventKeyboard::KeyCode::KEY_A)
{
Director::getInstance()->pause();
}
}
这个按下一次 第二次就不能用了吗？
