IAttributes

[bloodbao]

why in my function,it catch an expection?

Code: Select all

GRF3D::GRF3D(unsigned long Handle, s32 Witdh, s32 heigh){ 
	//*
    SIrrlichtCreationParameters params; 
    params.WindowId =   (void *) Handle ; 
	params.DriverType = EDT_DIRECT3D9; 
    params.WindowSize = dimension2d<s32>(Witdh,heigh); 
   params.EventReceiver = &receiver;

   device = createDeviceEx(params); 
   if (device != 0){ 
         device->setResizeAble(true); 
         env = device->getGUIEnvironment(); 
         driver = device->getVideoDriver(); 
         smgr = device->getSceneManager(); 
    } 
	io::IFileSystem* ifs=device->getFileSystem();
	ifs->createAndOpenFile("ff.h");///ok!
	ifs->getWorkingDirectory() ;///ok!
	ifs->addZipFileArchive("ff.zip");////ik!
	//ifs->createXMLReader("config.xml");///error
	//ifs->createEmptyAttributes(driver);///error
	//ifs->createXMLWriter(driver);///error
}

Do you actually have two devices? I don't see where you initialize the pointer at m_wnd->device. What happens if the above createDeviceEx() call fails? What will driver point to? What happens when you call createEmptyAttributes() with that 'bad' driver pointer?

Regardless, the best thing to do is get familiar with your debugger and use it to find out what is going on.

Actually,m-wnd->device is the same as device.
I want to know why it returns bad point!

How the hell should we know? We don't know what state the rest of your system is in. No matter how many exclamation! marks you use.

Please don't post your application problems in the Bugs forum. The chances of this being a bug with Irrlicht is as close to zero as makes no difference.
