i'm writing a mouse interface for ddraw, only one surface so theres no flipping. my prob, is that something in the getting the background of the mouse sprite is wrong. i use standard API functions in the mean time and i thought that will make it easier...

    
void CSprite::Get(IDirectDrawSurface *pdds, int x, int y, int gwidth, int gheight)
{
	HDC                 hdcImage;
	HDC                 hdc;

	pdds->GetDC(&hdc);          //getting surface dc

	DeleteObject(bitmap);       //deleting old background


	bitmap = CreateCompatibleBitmap(hdc, gwidth, gheight);
	hdcImage = CreateCompatibleDC(hdc);
	SelectObject(hdcImage,bitmap);

	BitBlt(hdcImage, 0, 0, gwidth, gheight, hdc, x, y, SRCCOPY);
		
	pdds->ReleaseDC(hdc);	
	DeleteDC(hdcImage); 
};
    

and it doesnt seem to put the area inside "bitmap". every other method in the Sprite class seem to work but this doesnt. anyone? Gil Edited by - gilzu on July 28, 2001 10:35:16 PM

C''mon people...
i know you can help me, i''m desparate here.
i''ve already designed a small RTS unit where
i have 2 units battling eachother and doing
whatever youll tell them to do, but,

this small thingy prevents me from using mouse
or putting it all to more speed.



help?

Im not exatly sure what u are trying to do, maybe u should dump the hdc and just use lpDDS->Blt() in your CSprite class.

Also I noticed u do not have any error checking - this could lead to unexpected crashing later on, if you check the return values of GetDC, CreateCompatibleDC, and BltBit for errors u could pinpoint the problem.

i did.
the problem is in the BitBlt() func.
but there''s no error code (it returns bool)
so i dunno whats wrong
