I've worked out how to fade out, but I can't work out how to fade back in!
Any ideas? I know this will have been asked before, but I have searched and have tried all the mthods used but none seem to work for me.

...
Have you tried doing the opposite of what you did to fade out?

Yes, and It doesn't work! I first tried using the original author's FadeIn function, but it wouldn't work either.

If you are using the original author's FadeIn function, you'll have to ask the original author. None of us know what he/she did.

I could always give you my fade-out function, and see if you could work it out?;).
| Code: |
void FadeIntoColor(u16 targetColor,u16* bmpPalette,int fadeSteps) {
int readX, step, red,green,blue;
u16 sourceColor;
for (step=0;step<=fadeSteps ;step++ ){
WaitForVsync();
step++;
for(readX = 0; readX < 256; readX++) {
sourceColor = bmpPalette[readX];
red = ((REDVALUE(sourceColor) * (fadeSteps-step)) + (REDVALUE(targetColor) * step)) /fadeSteps;
green = ((GREENVALUE(sourceColor) * (fadeSteps-step)) + (GREENVALUE(targetColor) * step)) /fadeSteps;
blue = ((BLUEVALUE(sourceColor) * (fadeSteps-step)) + (BLUEVALUE(targetColor) * step)) /fadeSteps;
paletteMem[readX] = RGB( red , green , blue );
}
}
}

I think that it may be an endless loop, not allowing the next function to happen, but I'm not sure.

It should work fine if you change your outer loop from
| Code: |
| for (step=0;step<=fadeSteps ;step++ ) |
to
| Code: |
| for (step=fadeSteps ;step>=0;step-- ) |
Fade out backwards, just like Dan said.
