(十一) 关于游戏场景
最后更新于：2022-04-01 16:12:29
这个场景作为弹出场景，主要介绍下游戏。。。还有自己的联系方式(*^__^*) ……
主要使用文本，就一个返回按键的响应函数
~~~
//返回按钮
void back(EventKeyboard::KeyCode keyCode, Event* pEvent);
~~~
同样要记得在析构函数中移除监听
~~~
AboutGame::~AboutGame()
{
_eventDispatcher->removeEventListenersForTarget(this);
}
~~~
文本已在XML文件中生成，直接调用即可
~~~
bool AboutGame::init()
{
if (!Layer::init())
return false;
//背景音乐
CocosDenshion::SimpleAudioEngine::getInstance()->stopBackgroundMusic(true);
CocosDenshion::SimpleAudioEngine::getInstance()->playBackgroundMusic("sound/BackgroundMusic1.mp3", true);
bool bRect = false;
do
{
auto size = Director::getInstance()->getWinSize();
//设置背景图片
auto m_background = Sprite::createWithSpriteFrameName("backgroundTollgateOne.png");
m_background->setPosition(Vec2(size.width/2,size.height/2));
m_background->setAnchorPoint(Vec2(0.5, 0.5));
this->addChild(m_background);
//设置监听器
auto m_listener = EventListenerKeyboard::create();
m_listener->onKeyReleased = CC_CALLBACK_2(AboutGame::back, this);
_eventDispatcher->addEventListenerWithSceneGraphPriority(m_listener, this);
//设置标签 并 获取中文文本
auto dictionary = Dictionary::createWithContentsOfFile("fonts/AboutMe.xml");
auto m_label3 = Label::createWithTTF(
((__String*)(dictionary->objectForKey("Others")))->getCString(),
"fonts/DFPShaoNvW5-GB.ttf",
25
);
m_label3->setDimensions(size.width / 3 * 2, size.height / 2);
m_label3->setColor(Color3B(255, 255, 255));
m_label3->setPosition(Point(size.width / 2, size.height/2));
this->addChild(m_label3);

);

m_label2->setColor(Color3B(0, 255, 0));
m_label2->setPosition(Point(size.width / 2, m_label1->getPositionY() - m_label2->getContentSize().height));
this->addChild(m_label2);
bRect = true;
} while (0);
return bRect;
}
//返回按钮
void AboutGame::back(EventKeyboard::KeyCode keyCode, Event* pEvent)
{
if (keyCode == EventKeyboard::KeyCode::KEY_ESCAPE)
{
//背景音乐
CocosDenshion::SimpleAudioEngine::getInstance()->stopBackgroundMusic(true);
CocosDenshion::SimpleAudioEngine::getInstance()->playBackgroundMusic("sound/game_start.mp3", true);
Director::getInstance()->popScene();
}
