-Hack is a display oriented dungeons & dragons - like game.
-Both display and command structure resemble rogue.
-(For a game with the same structure but entirely different display -
-a real cave instead of dull rectangles - try Quest)
-
-Hack was originally written by Jay Fenlason (at lincolnsudbury:
- 29 East St., Sudbury Mass., 01776) with help from
- Kenny Woodland, Mike Thome and Jon Payne.
-Basically it was an implementation of Rogue, however, with 52+ instead of 26
- monster types.
-The current version is more than thrice as large (with such new features as
- the dog, the long worms, the shops, etc.) and almost entirely rewritten
- (only the display routines are the original ones - I must rewrite these
- too one day; especially when you are blind strange things still happen).
-
-Files for hack:
- hack The actual game
- record Top 100 list (just start with an empty file)
- news Tells about recent changes in hack, or bugs found ...
- (Just start with no news file.)
- data Auxiliary file used by hack to give you the names
- and sometimes some more information on the
- objects and monsters.
- help Introductory information (no doubt outdated).
- hh Compactified version of help.
- perm An empty file used for locking purposes.
- rumors Texts for fortune cookies.
- (Some of these contain information on the game,
- others are just plain stupid. Additional rumors
- are appreciated.)
- hack.sh A shell script.
- (We have hack.sh in /usr/games/hack and
- hack in /usr/games/lib/hackdir/hack and all the other
- hack stuff in /usr/games/lib/hackdir - perhaps this
- will make the script clear.
- There is no need for you to use it.)
- READ_ME This file.
- Original_READ_ME Jay Fenlason's READ_ME
-
-System files used:
- /etc/termcap Used in conjunction with the environment variable
- $TERM.
- /bin/cat
- /usr/ucb/more
- /bin/sh Used when $SHELL is undefined.
-
-How to install hack:
-0. Compile the sources. Perhaps you should first look at the file config.h
- and define BSD if you are on a BSDtype system,
- define STUPID if your C-compiler chokes on complicated expressions.
- Make sure schar and uchar represent signed and unsigned types.
- If your C compiler doesnt allow initialization of bit fields
- change Bitfield. When config.h looks reasonable, say 'make'.
- (Perhaps you have to change TERMLIB in the makefile.)
-1. If it didnt exist already, introduce a loginname `play' .
-2. The program hack resides in a directory so that it is executable
- for everybody and is suid play:
- ---s--s--x 1 play 206848 Apr 3 00:17 hack
- Perhaps you wish to restrict playing to certain hours, or have games
- running under nice; in that case you might write a program play.c
- such that the program play is suid play and executable for everybody
- while all the games in /usr/games are readable or executable for
- play only; all the program play does is asking for the name of a game,
- checking that time-of-day and system load do not forbid playing,
- and then executing the game. Thus:
- -r-sr-sr-x 1 play 13312 May 24 12:52 play
- ---x------ 1 play 206848 Apr 3 00:17 hack
- If you are worried about security you might let play do
- chroot("/usr/games") so that no player can get access to the rest
- of the system via shell escapes and the likes.
- If you #define SECURE in config.h then hack will not setuid(getuid())
- before executing a chdir(). Hack will always do setuid(getuid()) with
- a fork. If you do not define UNIX then hack will not fork.
-3. The rest of the stuff belonging to hack sits in a subdirectory hackdir
- (on our system /usr/games/lib/hackdir) with modes
- drwx------ 3 play 1024 Aug 9 09:03 hackdir
- Here all the temporary files will be created (with names like xlock.17
- or user.5).
-4. If you are not really short on file space, creating a subdirectory
- hackdir/save (modes again drwx------) will enable users to save their
- unfinished games.
-
-The program hack is called
-$ hack [-d hackdir] [maxnrofplayers]
-(for playing) or
-$ hack [-d hackdir] -s [listofusers | limit | all]
-(for seeing part of the scorelist).
-The shell file hack (in this kit called hack.sh) takes care of
-calling hack with the right arguments.
-
-Send complaints, bug reports, suggestions for improvements to
-mcvax!aeb - in real life Andries Brouwer.
