These are the common parts from it's children. --- src/actor.h | 131 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 131 insertions(+) create mode 100644 src/actor.h (limited to 'src/actor.h') diff --git a/src/actor.h b/src/actor.h new file mode 100644 index 00000000..59e29b88 --- /dev/null +++ b/src/actor.h @@ -0,0 +1,131 @@ +/* + * The Mana Client + * Copyright (C) 2010 The Mana Developers + * + * This file is part of The Mana Client. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * any later version. + * + * This program 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.
