Hi, Is there a better, and far faster way, of clearing a texture than this:
  
for(int y=0; y<texYsize; y++)
{
   int offset = y*Pitch;
   memset(pTexture + offset,0,bytesperpixel*texXsize);
}
  
so as not to interfere with whatever directx puts at the end of each line? Or is it okay to overwrite it? Thanks alot, --Helicon56. [edited by - helicon56 on June 25, 2002 7:40:41 PM]

HRESULT hr;
DDBLTFX ddbltfx;

ZeroMemory(&ddbltfx, sizeof(ddbltfx));
ddbltfx.dwSize = sizeof(ddbltfx);
ddbltfx.dwFillColor = KEYCOLOR;
hr = pTexture->Blt(NULL, NULL, NULL, DDBLT_WAIT | DDBLT_COLORFILL, &ddbltfx);


i used DirectDraw7 hardware clear (maybe), very fast.

Thanks for your reply, but I''m talking about Direct 3D here. As far as i know, there''s no Blt function in LPDIREC3DTEXTURE8. So anymore suggestions?
Or is my suggestion the only way?
