From 973b3c3f5eca07cde2a5924524f26bd152fc5d77 Mon Sep 17 00:00:00 2001 From: toaster Date: Sat, 25 Aug 2018 16:46:45 +0100 Subject: [PATCH 1/2] Continuing my recent streak of making random lighting/colormap-related fixes to long-standing bugs: * Fix that thing where ALL transparent FOF planes were continuously fullbright unless encased in a fog which disables sprite fullbrightness, which was long-hated by many people in the community! * For backwards compatibility, setting flag 1 in that fog field (which is probably the most common "in-the-wild" usage of this feature) will continue to make objects un-fullbright. * For situations where you desperately want the behaviour to be enabled, you can apply fog flag 2. * Change the fadestart and fadeend range in which colormaps are generated. * The problem HERE was that the darkest light level reached by generated colormaps was actually slightly brighter than the darkest level reached by normal colormaps. * The typo I fixed does have SOME basis in fact - standard colormap lumps are 34 (33 in 0-indexing) long rather than 32 (31), but whoever wrote this didn't realise that the code for generating them didn't do it DooM style, just bright-to-dark with no extras on the end... --- src/r_data.c | 22 +++++++++++----------- src/r_plane.c | 4 ++-- src/r_things.c | 4 ++-- 3 files changed, 15 insertions(+), 15 deletions(-) diff --git a/src/r_data.c b/src/r_data.c index d19882dd3..e1d4b8935 100644 --- a/src/r_data.c +++ b/src/r_data.c @@ -1087,7 +1087,7 @@ INT32 R_ColormapNumForName(char *name) extra_colormaps[num_extra_colormaps].fadecolor = 0x0; extra_colormaps[num_extra_colormaps].maskamt = 0x0; extra_colormaps[num_extra_colormaps].fadestart = 0; - extra_colormaps[num_extra_colormaps].fadeend = 33; + extra_colormaps[num_extra_colormaps].fadeend = 31; extra_colormaps[num_extra_colormaps].fog = 0; num_extra_colormaps++; @@ -1115,7 +1115,7 @@ INT32 R_CreateColormap(char *p1, char *p2, char *p3) size_t mapnum = num_extra_colormaps; size_t i; UINT32 cr, cg, cb, maskcolor, fadecolor; - UINT32 fadestart = 0, fadeend = 33, fadedist = 33; + UINT32 fadestart = 0, fadeend = 31, fadedist = 31; #define HEX2INT(x) (UINT32)(x >= '0' && x <= '9' ?
