Does anyone have a solution/c++ code to make bmp images transparent on the fly without having to carry out 2 bitblt operations with the image and it's mask ? We want to develop a game in which there are many moving objects which have to be rendered transparent at new positions.
This method also uses several bitbld methods, so the lag is very high when you try to draw say 5-6 transparent images. Totally, there are 12 bitbld calls which slows down th game considerably. Any other suggestion ?

Do these images need to move while they are transparent?
I know NOTHING about game design, but I was thinking that perhaps a "faded image" could be called from a file if motion was not required. Then again, the machine would still have to integrate it into the scene somehow.
I'm GLAD I'm not a game designer...too many technical hurdles!
Looks like you might have to invent your own "fast" class methods.
Have fun!
