Directx Problems(0.4.2)

qwe · Post by **qwe** » Sun Dec 28, 2003 1:01 am

Whenever I compile an Irrlicht program using (E)DT_DIRECTX8, everything seems to be fine; however, when I run the program, it gives me(in the console):

Warning: Was not able to create Direct3D8 device.
Warning: Was not able to create DirectX8 device.
Warning: Could not create DirectX Driver.

And the program crashes.

I'm using MSVC++ 6.0 on winXP/win98se. the same thing happens on both machines.

OpenGL works fine.

and yes, i do have directX 8 installed

any ideas?

thanks

And the tutorials work? Did you try to create the device using bad settings like an unsupported video mode?

actually, the tutorials don't work. nor the technical demo(i think). I also just installed DX9 to get the latest dx8 dll's(some of them were debug versions) but that didn't help either.

**edit**

I lie. It doesn't like windowed mode, for some bizarre reason. Fullscreen works fine.

What VC do you have ?
I'm guessing Voodoo chip based...

I've got some Intel integrated video on the winXP box... I haven't tried compiling on the 98se yet, but that's got a Voodoo Banshee(voodoo 3000 stripped of a texture unit).

Ah! If you try to switch your desktop video mode from 32 to 16 bit (or the other way round) does this solve your problem?

OH DUH

that'll do it.

Really? Ok, then it is a bug in the engine.

no, actually, it's a directX shortcoming: it'll only do 3d in 16 and 32-bit color, not 24(which most people have). OpenGL has no problem.

It'd be nice if the engine changed the color depth for windowed mode though

ah, ok.

That's what I'll do

or you could do what I did, a simple test at the beginning of the program:
create a null device, grab the desktop depth, if it's not 16 or 32 error out.
