From 13f361d8aa5c897a1f820e65da5c63e5198c218c Mon Sep 17 00:00:00 2001 From: Robert Zubeck Date: Tue, 12 Jun 2007 01:39:29 +0000 Subject: [PATCH] Clamping is a useful abstraction, and easy to slip up on. Maybe more math idioms will end up in here as well? git-svn-id: svn+ssh://src.earth.threerings.net/nenya/trunk@257 ed5b42cb-e716-0410-a449-f6a68f950b19 --- src/as/com/threerings/flash/MathUtil.as | 40 +++++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 src/as/com/threerings/flash/MathUtil.as diff --git a/src/as/com/threerings/flash/MathUtil.as b/src/as/com/threerings/flash/MathUtil.as new file mode 100644 index 00000000..019a8c21 --- /dev/null +++ b/src/as/com/threerings/flash/MathUtil.as @@ -0,0 +1,40 @@ +// +// $Id$ +// +// Nenya library - tools for developing networked games +// Copyright (C) 2002-2007 Three Rings Design, Inc., All Rights Reserved +// http://www.threerings.net/code/nenya/ +// +// This library is free software; you can redistribute it and/or modify it +// under the terms of the GNU Lesser General Public License as published +// by the Free Software Foundation; either version 2.1 of the License, or +// (at your option) any later version. +// +// This library is distributed in the hope that it will be useful, +// but WITHOUT ANY WARRANTY; without even the implied warranty of +// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
