Error initializing direct3d

Quote:

I can't get the current program to work

Can you describe what the problem is?

Does it compile? Does it link?

It compiles with no errors in the output log, but since there is a message inside the program that pops up when the direct3d isn't initialized, that's whats happening when I compile it. A window pops up the message.

Most, if not all, DirectX functions return a code you can use to determine if the function call was successful, or if not successful, help you to determine what error was encountered.

You do check for some errors, but you're not giving yourself any information about where or why it occurred.

For instance, your Direct3d_Init function may return false for several reasons. Instead of just returning false if you detect something wrong, give yourself a break and display a messagebox or output a debug string so you have some idea where the problem lies.

For instance:

d3d = Direct3DCreate(...);if( d3d==NULL ) {   MessageBox(NULL,"Failed to create the D3D interface","Creation Failure",MB_OK);   return false;}HRESULT hr = d3d->CreateDevice(...);if( FAILED(hr) ) {   MessageBox(NULL,DXGetErrorDescription9(hr),"Failed to create the device",MB_OK);   return false;}

It only takes milliseconds to check return codes, but takes you hours to just scan code. Give some of the above techniques a try.

EDIT: Note - if this code ran at one time, it's much more likely one of your parameters is incorrect than the code itself is incorrect.

So if I'm getting a generic message about the direct3d failing to initialize, where would I start to put the custom made message? Right under the d3d -> CreateDevice function? And what do I do with the original message put //'s in front to get it to shut up?

Not quite sure but I think the problem is here in MyGame.cpp

bool Game_Init(HWND window)
{
//Initialize Direct3D
if(!Direct3D_Init(window, SCREENW, SCREENH, false));
{
MessageBox(0, L"Error initializing Direct3D", L"Error", 0);
return false;
}

//Initialize DirectInput
if(!DirectInput_Init(window));
{
MessageBox(0, L"Error initializing DirectInput", L"Error", 0);
return false;
}


You're putting semicolons after an if statement in both of those.

Should look like this:


bool Game_Init(HWND window)
{
//Initialize Direct3D
if(!Direct3D_Init(window, SCREENW, SCREENH, false))
{
MessageBox(0, L"Error initializing Direct3D", L"Error", 0);
return false;
}

//Initialize DirectInput
if(!DirectInput_Init(window))
{
MessageBox(0, L"Error initializing DirectInput", L"Error", 0);
return false;
}

Without the semicolons right after the if statements.

Also wth is parameter 5 from this function in MyDirectX.cpp? Not sure what that symbol is *shrug*

//Create surface
result = d3ddev -> CreateOffscreenPlainSurface(
info.Width, //Width of the surface
info.Height, //Height of the surface
D3DFMT_X8R8G8B8, //Surface format
D3DPOOL_DEFAULT, //Memory pool to use
ℑ, //Point to the surface
NULL); //Reserved (always NULL)

Wow! You guys are amazing. Once again you guys have bailed me out. It was the silly semicolons. I just don't understand how I can miss such small things. The other question you had, that was supposed to be an ampersand. I'm not sure what happened there. But the program works. I'm trying hard to learn how to program, but it seems like every time I do, I run into more problems. As long as I have you guys for help, I'll keep trying.

Thanks for your time, I appreciate it.

Hey I think your problem is with the device creation parameters. Try using D3DCREATE_HARDWARE_VERTEXPROCESSING. This problem might arise because you are trying to create a HAL device. Normally we use SOFTWAREVERTEXPROCESSING when we create a software device.. Check it out.

Cool, thanks for the pointer. The only reason I used the HAL was because it was in the book. To tell you the truth, I don't even know what the heck HAL is other than the computer in Space Odyssey 2001 :).
