How do I get the background to fade through all the colors of rgb() smoothly? I can do it just by incrimenting each portion r,g,b in order, but then it will "jump" to a complete different color sometime. I just need a way for it to fade smoothly through all the colors. How can I do this?

Im not sure of how exactly you'd go about this so I don't have code but instead of increasing each colour value try increasing one of them at a time and checking if they equal 255, if so move on to the next value.

Still I havent tried it but its something to think about.

Classic or Pro? Post some code so we can see what your working with.

Here's for Pro (make it a sprite then set sprite diffuse):

+ Code Snippet

` Fade current screen to black using a sprite
get image 50,0,0,800,600,1
sprite 100,0,0,50
for t=255 to 0 step -1
 set sprite diffuse 100,t,t,t
 sync
next t

Or do you mean filling the background with one color at a time of all 16 million colors?

Something like this perhaps?

+ Code Snippet

sync on : sync rate 60 : autocam off
make object cube 1,1
position camera 0,0,-5
do
   a1#=wrapvalue(a1#+0.5)
   a2#=wrapvalue(a2#+0.2)
   a3#=wrapvalue(a3#+1.5)
   r#=128+(127.0*sin(a1#))
   g#=128+(127.0*cos(a2#))
   b#=128+(127.0*sin(a3#))
   color backdrop rgb(r#,g#,b#)
   turn object left 1,0.5
   pitch object up 1,0.2
   roll object left 1,0.3
   sync
loop

Tinker with the values until you get color effect you like
