How do I get the device?

[disanti]

Error:

C:\irrlicht\examples\Pong\text.cpp(23) : error C2065: 'device' : undeclared identifier

Code in text.cpp:

Code: Select all

void counter(int number, int x, int y, char directory[255])
{
	video::ITexture* numbers = driver->getTexture(directory);
}

In main.cpp:

Code: Select all

//MAIN
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hpInstance, LPSTR lpcmd, int nshowcmd)
{
	//make the device
	IrrlichtDevice *device =
		createDevice(EDT_DIRECTX8, dimension2d<s32>(640, 480), 16, false, false, 0);

	//set the window captions
	device->setWindowCaption(L"Pong");
	
	//make the drivers
	ILogger* logger = device->getLogger();
	IVideoDriver* driver = device->getVideoDriver();
	ISceneManager* smgr = device->getSceneManager();
	IGUIEnvironment* guienv = device->getGUIEnvironment();
	
etc...

How can I get the device and all that other junk into text.cpp so I can make a basic counter?

You could either pass a pointer to the device into your counter function, or make the device a global variable.

How??

I tried:

Code: Select all

	//make the device
	IrrlichtDevice *device;

	//make the drivers
	ILogger *logger;
	IVideoDriver *driver;
	ISceneManager *smgr;
	IGUIEnvironment *guienv;

//MAIN
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hpInstance, LPSTR lpcmd, int nshowcmd)
{
	device = createDevice(EDT_DIRECTX8, dimension2d<s32>(resX, resY), depth, false, false, 0);

	//set the window captions
	device->setWindowCaption(L"CPU Pong");

	//make the drivers

	logger = device->getLogger();
	driver = device->getVideoDriver();
	smgr = device->getSceneManager();
	guienv = device->getGUIEnvironment();

Then in text.cpp:

Code: Select all

void counter(int number, int x, int y)
{
	char curdir[255];
	getCurrentDir(curdir);

	video::ITexture* numbers = *driver->getTexture(strcat(curdir,"media\\numbers.bmp"));
}

Now it gives me this:
C:\irrlicht\examples\Pong\text.cpp(22) : error C2065: 'driver' : undeclared identifier
C:\irrlicht\examples\Pong\text.cpp(22) : error C2227: left of '->getTexture' must point to class/struct/union

I'm very new to pointers.

count() doesn't exist in the same scope as your main()

You will need to pass the device pointer to count.

Code: Select all

void counter(IrrlichtDevice *device, int number, int x, int y) 
{ 
   char curdir[255]; 
   getCurrentDir(curdir); 

   video::ITexture* numbers =  device->getVideoDriver()->getTexture(strcat(curdir,"media\\numbers.bmp")); 
} 

Then call it via

Code: Select all

counter(device,1,10,20);

If you were using classes, you could have something like myclass::count() and myclass::main().

Thanks! Now it works!

disanti, IMNSHO: before you continue with IrrLicht, you should probably have a better understaning of C and C++

I suggest the following:
