Hi,
I''m having trouble creating offscreen surfaces using this function I wrote. This is part of a class called Sprite (duh) and the integer mode variable is just for the settings of whether it should be created in video memory or system memory.
The g_lpdd is a IDIRECTDRAW7 interface that has been initialized and it does work - trust me.
The Post_Error function just calls a MessageBox function and puts the error string on the message box - and does it pretty damn well
So take a look and please just tell me I did something dumb
Sprite::Sprite(int xx, int yy, int wwidth, int hheight, int mode)// mode - set to DDSCAPS_VIDEOMEMORY or DDSCAPS_SYSTEMMEMORY
{
Sprite::x = xx;
Sprite::y = yy;
Sprite::width = wwidth;
Sprite::height = hheight;
Sprite::cur_frame = 0;
memset(&g_ddsd,0,sizeof(DDSURFACEDESC2));
Sprite::s_ddsd.dwSize = sizeof(Sprite::s_ddsd);
Sprite::s_ddsd.dwFlags = DDSD_CAPS | DDSD_WIDTH | DDSD_HEIGHT | DDSD_CKSRCBLT;
Sprite::s_ddsd.dwWidth = wwidth;
Sprite::s_ddsd.dwHeight = hheight;
Sprite::s_ddsd.ddsCaps.dwCaps = DDSCAPS_OFFSCREENPLAIN | mode; //Different modes - DDSCAPS_VIDEOMEMORY or DDSCAPS_SYSTEMMEMORY
if(g_lpdd->CreateSurface(&(Sprite::s_ddsd),&(Sprite::lpddssprite),NULL)!=DD_OK) //dependant on a global - bad
{
Post_Error("Could not create a surface for a sprite!");
}
Sprite::s_ddsd.ddckCKSrcBlt.dwColorSpaceLowValue = 0;
Sprite::s_ddsd.ddckCKSrcBlt.dwColorSpaceHighValue = 0;
DDCOLORKEY color_key = Sprite::s_ddsd.ddckCKSrcBlt;
Sprite::lpddssprite->SetColorKey(DDCKEY_SRCBLT, &color_key);
}
Sorry about the ugly text formatting...
Any help would be great
Thanks,
Destroyer
P.S. How do you make those little boxes with code in them in your posts?
