Passing a value to routines in the Irrlicht DLL?

[Liquidream]

Hi all,

I am modifying the CIrrDeviceWin32.cpp in order to change how my actual Irrlicht window is created (frameless, Z-ordering, etc.) which has worked fine so far.

Now I want to be able change things at runtime. Specifically, I want to be able to pass a value from my Main irrlicht program to this routine (located in the DLL?) so that I can change HOW my window behaves at runtime.

For example: in the LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) of CIrrDeviceWin32.cpp, I have added extra cases (WM_ACTIVE, etc) to handle the Z-ordering of the window, whether it can be activated, etc. These are currently always being run/called. What I would like to only use these extra cases based on a variable set by my main application.

Does anyone know how can I pass a variable (or set a value) into these routines in CIrrDeviceWin32.cpp at runtime?

Hope this makes sense!

Implement it in the class CIrrDeviceWin32 (e.g. setYourCustomValue() ). In the WndProc you can then access it with:

Code: Select all

dev = getDeviceFromHWnd(hWnd);
if (dev) {
	dev->getYourCustomValue();
}

Wow! Thanks for the quick reply. Will give it a go!

Another question: how can I call setYourCustomValue() (if I add it into class CIrrDeviceWin32) from my main program as I don't think it is accessible from Irr::Device-> or something like this?

Thank you for your help!

You'll have to add them as virtual member functions to the IrrlichtDevice interface (IrrlichtDevice.h) and possibly as empty function to the class CIrrDeviceStub a well. Then you can access them via Irr::Device-> .
