I''ve spent about an HOUR going over the D3D9 tutorial that comes with the DirectX9 SDK, about how to set up a basic program. So far, I''ve created a window, requested an interface, created a device, and tried to "Clear()" it to a certain color. All of it works, except the Clear() part. I have some basic error checking, and there doesn''t seem to be any problems (though if I set the d3dpp.Windowed to false (ie: fullscreen) I get a "Cannot Create Device error"... strange) By default, my window is white, and it stays white. Having read the description of Clear(), I would expect it to become the color I assign it. Take a look at my code:
if (FAILED(ID3D = Direct3DCreate9(D3D_SDK_VERSION)))
{
MessageBox(NULL, "Could not create Direct 3D 9 interface", "Error", MB_OK);
}
D3DPRESENT_PARAMETERS d3dpp;
ZeroMemory(&d3dpp, sizeof(d3dpp));
d3dpp.Windowed = false;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
d3dpp.BackBufferFormat = D3DFMT_UNKNOWN;
if (FAILED(ID3D->CreateDevice( D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, myWindow,
D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&d3dpp, &device ) ) )
{
MessageBox(NULL, "Could not create device", "Error", MB_OK);
}//endif
//paint the screen red
device->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,0), 1.0f, 0);
The code is almost word for word out of the MS tutorial, yet I still can''t get my window to become a certain color. Perhaps I am misinterpreting the actual function of Clear(), though it does sound like, to me, that you can set the color of the background using clear.
I know this is a really stupid problem, but help is greatly appreciated
