From 2870e19f7f6526b7a68b94cf2492fd58564fa072 Mon Sep 17 00:00:00 2001 From: Monster Iestyn Date: Wed, 27 Jul 2016 19:56:21 +0100 Subject: [PATCH] Take out fixedheight-based hacks for checking if floor or ceiling! Use an "isceiling" boolean for that instead This apparently fixes most of the issues with ceiling slopes in Boinciel's SUGOI map --- src/hardware/hw_main.c | 70 ++++++++++++++++++++---------------------- 1 file changed, 34 insertions(+), 36 deletions(-) diff --git a/src/hardware/hw_main.c b/src/hardware/hw_main.c index ca4e000b..5251e0b3 100644 --- a/src/hardware/hw_main.c +++ b/src/hardware/hw_main.c @@ -66,9 +66,9 @@ static void HWR_ProjectPrecipitationSprite(precipmobj_t *thing);
