Direct3D init --> using DirectX 8.1

VB Code:

'// Initialise : This procedure kick starts the whole process.
'// It'll return true for success, false if there was an error.
Public Function Initialise() as Boolean
On Error Goto ErrHandler:
 
Dim DispMode as D3DDISPLAYMODE '//Describes our Display Mode
Dim D3DWindow as D3DPRESENT_PARAMETERS '//Describes our Viewport
 
Set Dx = New DirectX8 '//Create our Master Object
Set D3D = Dx.Direct3DCreate() '//Make our Master Object create the Direct3D Interface
 
D3D.GetAdapterDisplayMode D3DADAPTER_DEFAULT, DispMode '//Retrieve the current display Mode
 
D3DWindow.Windowed = 1 '//Tell it we're using Windowed Mode
D3DWindow.SwapEffect = D3DSWAPEFFECT_COPY_VSYNC '//We'll refresh when the monitor does
D3DWindow.BackBufferFormat = DispMode.Format '//We'll use the format we just retrieved...
 
'//This line will be explained in detail in a minute...
Set D3DDevice = D3D.CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, FrmMain.Hwnd, _
                                                     _ D3DCREATE_SOFTWARE_VERTEXPROCESSING, _
                                                     _ D3DWindow)
 
Initialise = True '//We succeeded
Exit Function
ErrHandler:
'//We failed; for now we wont worry about why.
Initialise = False
End Function

This code should work with DirectX 8.1 but ther's still a little
problem left:

D3DADAPTER_DEFAULT is not found anywhere in the DirectX libary.

Mybe this code was written for 8.0?

What can I use instead of D3DADAPTER_DEFAULT?

Any ideas?

thx!

have you tried 1 or 0?

Did you add the DX8.1 type library to your references list? The constant is the same for 8.0 and 8.1.

I found the problem:

CONST_D3DCONST.D3DADAPTER_DEFAULT

is the variable

thx!

so what is it? not 1 or 0?

don't know...

I guess it's 0 because the reference says 0 is for 'unknown adapter'

but now there's a nice new problem:

after direct3d init, the system crashes if I run
the app in full-screen mode.

when I run it windowed, all works fine.

I guess that will also take some time to figure out.

Misan, D3DADAPTER_DEFAULT == 0.

vbzero, Check your back buffer format. It is probably unsupported. Check in the DirectX Caps Viewer (it was installed where your SDK was installed, and its in the start menu). Check what back buffer formats your card supports, and use one of them. Also make sure you arent switching into a mode your monitor doesnt support.

I would NOT advise working on your project and testing it in fullscreen. You may end up having to restart your computer A LOT. Just a word of advice.

You're right!

The problem is the backbuffer format. But isn't there a
possibility to let the program find out which backbuffer
is correct?

How did they do that in commercial games?

My backbuffer:

VB Code:

// Setting the new display format
                //
                D3DDispMode.Format          =   CONST_D3DFORMAT.D3DFMT_X8R8G8B8;
                D3DDispMode.Height          =   480;
                D3DDispMode.Width           =   640;
                
                //
                // Setting the new window format
                //
                D3DWindow.Windowed          =   0;
                D3DWindow.SwapEffect        =   CONST_D3DSWAPEFFECT.D3DSWAPEFFECT_FLIP;
                D3DWindow.BackBufferCount   =   1;
                D3DWindow.BackBufferFormat  =   D3DDispMode.Format;
                D3DWindow.BackBufferHeight  =   480;
                D3DWindow.BackBufferWidth   =   640;
                D3DWindow.hDeviceWindow     =   Me.hWnd;

When you Query the adapter, you are querying the CURRENT settings. You need some extra code to do Caps Checks to find out which cards support which back buffer formats.

I just found a tutorial to that...

thx very much!
