Understanding DirectDraw ...

Recommended Posts

Hi... I''m currently learning DirectDraw, but there''s a point I don''t understand: Let''s say I want to make a sprite move on some blank surface... I need to render this blank surface? I mean, I must load a blank bitmap (background: black) on my surface, and then do whatever I want with the sprite... right? I can''t declare my surface to Nothing to have it blank huh? Thanks TeraZen, Last of the Returners

you can use this code to fill a surface with one colour:


DDBLTFX ddbltfx;

/* Set size of structure */
ddbltfx.dwSize = sizeof( ddbltfx );
/* Set fill colour to specified colour */
ddbltfx.dwFillColor = dwColour;

/* Do Fill */
/* First parameter is a pointer to a RECT specifying want
portion of the surface to fill. NULL means all of it */
dderval = lpDDSurface->Blt( NULL, NULL, NULL, DDBLT_COLORFILL | DDBLT_WAIT, &ddbltfx );
