* $Id: act.c,v 1.29 2008/03/27 09:07:07 devel Exp $ (c) D.Brockhaus
*
* Act is the counterpart to Do. When a character wants to do something, he calls the
* corresponding Do-function. This triggers the execution of the Act-function of the
* same name some time later (exact time depends on character speed and the action).
*
* Act is the part which actually does something. act_walk() moves a character from
* one tile to the next, act_attack hits (and possibly hurts) a character etc.
