From 1a5c55eb89c22e8822ec057a3731a6d753f13859 Mon Sep 17 00:00:00 2001 From: Michael Smith Date: Sat, 30 Apr 2022 00:23:31 +0100 Subject: Centralise engine access, add Portal FOV changer - A bunch of stuff is now defined in one header, engineapi.h - engineapi.c is responsible for setting up any interfaces/stuff that's used in more than one place - mkgamedata is pretty much rewritten and now supports nested conditionals - gamedata variables no longer have the gamedata_ prefix because it was just annoyingly long all the time - vcall macros are somewhat revamped and support dynamic (gamedata) indices - Portal 1 FOV can be set anywhere from 75-120 using fov_desired - tested in both the main versions currently used by runners - A few typos were also fixed ("intput," "writeable," "indexes") --- src/ent.c | 49 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 src/ent.c (limited to 'src/ent.c') diff --git a/src/ent.c b/src/ent.c new file mode 100644 index 0000000..b621e0b --- /dev/null +++ b/src/ent.c @@ -0,0 +1,49 @@ +/* + * Copyright © 2022 Michael Smith + * + * Permission to use, copy, modify, and/or distribute this software for any + * purpose with or without fee is hereby granted, provided that the above + * copyright notice and this permission notice appear in all copies. + * + * THE SOFTWARE IS PROVIDED “AS IS” AND THE AUTHOR DISCLAIMS ALL WARRANTIES WITH + * REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF MERCHANTABILITY + * AND FITNESS.
