Hi,
I'w writing a simple side scrolling game using the Direct Draw 7 library.
I would like to know if there is a way to implement the alpha blending blitting using some DD function (hardware).I wrote a software alpha blending function
but when I use it I need to lock/unlock the sufaces with a resulting decrease in the fps of the game especially in older machines.
Thanks in advance.
