cocos2dx学习笔记：判断当前平台

最近项目中用到了cocos2dx来开发一个基于陀螺仪的demo，忙了半个星期，一边学习一边开发，总算搞了出来。这里备份下开发中学习到的一些cocos2dx知识。

判断当前平台：

实例代码：

bool AppDelegate::applicationDidFinishLaunching() {
    CCDirector* pDirector = CCDirector::sharedDirector();
    CCEGLView* pEGLView = CCEGLView::sharedOpenGLView();
    pDirector->setOpenGLView(pEGLView);

//如果是windows 就缩放0.7。
#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)
	pEGLView->setFrameZoomFactor(0.8f);
#endif

    pDirector->setDisplayStats(true);
    pDirector->setAnimationInterval(1.0 / 60);
    CCScene *pScene = HelloWorld::scene();
    pDirector->runWithScene(pScene);
    return true;
}

 源码参考：

CC_TARGET_PLATFORM 宏的定义在【 cocos2d-x-2.2.1\cocos2dx\platform\CCPlatformConfig.h 】文件中。
