【cocos2dx 3.2】别碰白块禅模式

时间：2022-04-08 12:10:14

注：

1.没有实现倒计时30秒，而是顺数30秒

2.打包好的apk，不能调用系统时钟，所以计时功能只有在vs上有效

3.apk地址:http://pan.baidu.com/share/link?shareid=3877337685&uk=185595768

【cocos2dx 3.2】别碰白块禅模式


调整屏幕大小：

AppDelegate.cpp：

bool AppDelegate::applicationDidFinishLaunching() {

    auto director = Director::getInstance();
    auto glview = director->getOpenGLView();
    if(!glview) {
		//修改屏幕大小
        glview = GLView::createWithRect("MyBlock",Rect(0,0,286,512),1.0f); 
        director->setOpenGLView(glview);
    }

	glview->setDesignResolutionSize(268,512,ResolutionPolicy::EXACT_FIT);  

    director->setDisplayStats(true);

    director->setAnimationInterval(1.0 / 60);

    auto scene = HelloWorld::createScene();

    director->runWithScene(scene);

    return true;
}

卡片类：

	void setLineIndex(int index);
	int getLineIndex();

	void removeCard();

	//获取向量里的对象
	static Vector<Card*> *getCard();

	//向下移动一行
	void moveDown();

	//清空向量
	static void renewVector();

private:

	//用向量存放Card
	static Vector<Card*> *cards;

	//记录卡片所在的行
	int lineIndex;

};
