首先在AppDelegate.cpp加入以下代码，一定要在AppDelegate::applicationDidFinishLaunching()上，声明用的。
#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)
HelloWorld *g_layer;void Win32SetKeyLayer(HelloWorld *layer)
{g_layer = layer;
}void Win32KeyHook( UINT message,WPARAM wParam, LPARAM lParam )
{CCLog("Win32KeyHook message %d wParam %d lParam %d", message, wParam, lParam);if (g_layer)g_layer->onWin32KeyEvent(message, wParam, lParam);
}
#endif在AppDelegate::applicationDidFinishLaunching()中
bool AppDelegate::applicationDidFinishLaunching() {// initialize directorCCDirector* pDirector = CCDirector::sharedDirector();CCEGLView* pEGLView = CCEGLView::sharedOpenGLView();#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)// 2012.11.07 加入键盘处理代码pEGLView->setAccelerometerKeyHook(Win32KeyHook);///
#endif // CC_PLATFORM_WIN32pDirector->setOpenGLView(pEGLView);// turn on display FPSpDirector->setDisplayStats(true);// set FPS. the default value is 1.0/60 if you don't call thispDirector->setAnimationInterval(1.0 / 60);// create a scene. it's an autorelease objectCCScene *pScene = HelloWorld::scene();// runpDirector->runWithScene(pScene);return true;
}在HelloWorldScene.cpp中
CCScene* HelloWorld::scene()
{// 'scene' is an autorelease objectCCScene *scene = CCScene::create();// 'layer' is an autorelease objectHelloWorld *layer = HelloWorld::create();// add layer as a child to scenescene->addChild(layer);extern void Win32SetKeyLayer(HelloWorld *layer);Win32SetKeyLayer(layer);// return the scenereturn scene;
}
