Yep, another coding issue: UTIL_ScreenFade Created 3 years ago2021-06-12 01:30:10 UTC by Alexis_of_Steel

Hello! I was wondering how to make UTIL_ScreenFade last longer than 16 seconds (by default, that is the maximum duration of this UTIL).
I mean, is it possible to edit the code of UTIL_ScreenFade so that the duration of the screen fade effect lasts longer than 16 seconds?
In my case, I want it to last 30 seconds, no more:

UTIL_ScreenFade( pPlayer, Vector(255,0,0), 1, 30, 128, FFADE_IN ); // float fadeHold only lasts 16 s

I have searched for a tutorial and didn't really find anything.
Thanks in advance.

You can modify the UTIL_ScreenFadeBuild function to make this work:

void UTIL_ScreenFadeBuild( ScreenFade &fade, const Vector &color, float fadeTime, float fadeHold, int alpha, int flags )
{
    fade.duration = FixedUnsigned16( fadeTime, 1<<8 );        // 8.8 fixed
    fade.holdTime = FixedUnsigned16( fadeHold, 1<<8 );        // 8.8 fixed
    fade.r = (int)color.x;
    fade.g = (int)color.y;
    fade.b = (int)color.z;
    fade.a = alpha;
    fade.fadeFlags = flags | FFADE_LONGFADE;
}

The FFADE_LONGFADE flag indicates that a longer fade time can be used. The parameter to FixUnsigned16 has to be modified for both calls to use 1 << 8.

Oh, God. It worked! Thanks a lot, Solokiller!
