From 374ae0fbc44db36d9abb6b5b1fe065bc3949e201 Mon Sep 17 00:00:00 2001 From: Matthew Wozniak Date: Thu, 17 Nov 2022 14:34:47 -0300 Subject: Add VGUI HUD overlay drawing feature Currently only supports Orange Box and Left 4 Dead branches. There's quite a large amount of gamedata involved in making this work, and figuring it out for the likes of Portal 2 doesn't seem like a major priority at the moment. --- src/hud.h | 72 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 72 insertions(+) create mode 100644 src/hud.h (limited to 'src/hud.h') diff --git a/src/hud.h b/src/hud.h new file mode 100644 index 0000000..8ea0877 --- /dev/null +++ b/src/hud.h @@ -0,0 +1,72 @@ +/* + * Copyright © 2022 Matthew Wozniak + * + * 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.
