Cocos2dx-v4.0学习-HelloCpp

1. 你好HelloCpp

打开工程cocos工程后，我们打开

2. 程序入口main.cpp

主要是创建了AppDelegate对象实例，使用其run方法

main () {
	AppDelegate app;
	return Application::getInstance()->run();
}

3. 初识AppDelegate

class  AppDelegate : private cocos2d::Application
{
public:
    AppDelegate();
    virtual ~AppDelegate();

    virtual void initGLContextAttrs();

    /**
    @brief    Implement Director and Scene init code here.
    @return true    Initialize success, app continue.
    @return false   Initialize failed, app terminate.
    */
    virtual bool applicationDidFinishLaunching();

    /**
    @brief  Called when the application moves to the background
    @param  the pointer of the application
    */
    virtual void applicationDidEnterBackground();

    /**
    @brief  Called when the application reenters the foreground
    @param  the pointer of the application
    */
    virtual void applicationWillEnterForeground();
};

• initGLContextAttrs: 设置OpenGL上下文属性
• applicationDidFinishLaunching：实现导演类与初始化场景
  • FPS设置（Frames Per Second）
  • 设计分辨率
  • 创建场景HelloWorld
• applicationDidEnterBackground：程序进入后台的时候调用
• applicationWillEnterForeground：程序进入前台的时候调用

4. 场景HelloWorldScene

HelloWorld继承了Scene， 初始化时创建里文字、精灵，点击关闭事件等
