Doing A Flip

Recommended Posts

My primary surface doesn''t flip with my back surface!!!, I was told to show my Surface Init code so here it is, everything looks right to me, I use: while (FAILED(lpDDSurfacePrimary->Flip(NULL, DDFLIP_WAIT))); to flip the surfaces and it just displays black when I blit to the back surface but works when I blit to the primary, anyone have any ideas??
  
	memset(&ddSurfaceDesc,0,sizeof(ddSurfaceDesc));
	ddSurfaceDesc.dwSize = sizeof(ddSurfaceDesc);
	ddSurfaceDesc.dwFlags = DDSD_CAPS | DDSD_BACKBUFFERCOUNT;

	// we need to let dd know that we want a complex 

	// flippable surface structure, set flags for that

	ddSurfaceDesc.ddsCaps.dwCaps = DDSCAPS_PRIMARYSURFACE | DDSCAPS_COMPLEX | DDSCAPS_FLIP;
	ddSurfaceDesc.dwBackBufferCount = 1;

	// set the backbuffer count to 1, 2 for triple bufferin


	// create the primary surface

	if (FAILED(lpMainDD->CreateSurface(&ddSurfaceDesc,&lpDDSurfacePrimary,NULL)))
		return -1;


	ddscaps.dwCaps = DDSCAPS_BACKBUFFER;
	if (FAILED(lpDDSurfacePrimary->GetAttachedSurface(&ddscaps,&lpDDBackSurface)))
		return -1;
	DDSURFACEDESC2 ddSurfaceDesc;	//Surface Description

	DDSCAPS2 ddscaps;              // a direct draw surface capabilities struct

Well, I''m not sure if I understand your problem.
On which surface are you doing your blit''s ? Is it the primary surface or the backbuffer ? In case you do it to the primary surface then that''s the problem. If you have a backbuffer you should do all the blitting to it.

I hope that solves your problem. If not, I''m sorry.

if your copying the info to the backbuffer and not switching anything to the primary surf, obviously its not displaying anything. i dont see how you newbies get stuck on these stupid problems, when the code is right in front of your face. im not sure if understood your problem though
