You've got two choices - SET GAMMA, which doesn't work on all cards, and will only work in FSEX mode anyway.
The alternative (better and the way I do it is to use sprites) - Grab the area you want (or a black area), and use that as a sprite.

use set gamma:

rem Fade in
for i = 1 to 255
set gamma i,i,i
next i

rem Fade out
for i = 255 to 1 step -1
set gamma i,i,i
next i

It'll only work in exclusive mode, though.

You can also put a large sprite over the whole screen and use set sprite alpha to fade that in / out.

Try FADE BITMAP bitmap number,fade value

If bitmap is zero then the default screen is used.

Try putting this code into your game loop:



It will fade the screen in and back out again.

This is, of course, assuming you want the whole screen to fade in/out.

I find that Fade Bitmap tends to be slow...

You can use a sprite in front of your camera, and play with the alpha values. Just remeber to keep it real close

what if you wanted to fade an object in/out... but fading from visible to invisible? Alpha Mapping does not work as the 3d plain has a transparent texture, with alpha the transparent color turns solid black
