adv770a.tgz Game version 2.07 This package contains ANSI C sources (programmatically derived from the A-code master source) of my 770 points version of Adventure. The game (generally known as Adv770) is made available under GPL3 and may be freely distributed and archived. All you need to build a game executable out of the sources provided in this package is an ANSI C compiler (e.g. gcc). Please see http://mipmip.org/c-build.shtml for details. For more A-code information, please visit my web-site: http://mipmip.org/ Hope you enjoy the game!

On other platforms it is only useful for hints on building a game executable. If you cannot use the script, more explicit instuctions can be found in http://mipmip.org/c-build.shtml. ________________________________________________________________________ A-code game command line options (A-code version 12.53) This document describes command line options available when running any A-code game built using A-code 12 engine. The behaviour of the game is generally regulated by the self-documented file acode.conf, which can be found in the acode directory, automatically created in player's home directory. Where command line options refer to particular aspects covered by the configuration file, they override the configuration file settings. Conventions: * Angle brackets denote a symbolic string to be replaced by something appropriate. E.g. would be replaced by the name of a file (with no surrounding angel brackets). * Square brackets [ ] denote something optional. So e.g. -l[] means that the name of the log file may be omitted. * Braces { } denote a list of permissible values, separated by vertical bars |. E.g. -b[{0|1|2}] means the -b may be optionally (square brackets!) followed by one of the three digits zero,one or two. * Where a value can be specified with a command line option, the syntax shown is that of the value abutting directly to the option specification letter. However, an equality sign = can be placed between the two, so that -b0 is equivalent to -b=0. * Some options can have either word or numerical values; the two styles are shown on two separate lines and are exactly equivalent. The following command line options are valid for both the browser and the console display modes: -n Force a new game. By default, if a previous game session got somehow forcibly interrupted (e.g. by the game process being killed for whatever reason), the interrupted session is automatically resumed when the game is restarted. The -n option overrides this behaviour and forces the interrupted session to be forgotten. -b[{no|yes|all}] -b[{0|1|2}] Set or invert the blank line setting. If set to zero blank lines are inserted before and after each prompt. If the value is 1, blank lines around '?' prompts are suppressed, resulting in a more compact display. If the value is 2, then ALL blank lines are suppressed, for super-compact, but less readable output. If no value is specified, the new setting is 0 or 1, inverting the A-code default for this game. In old-style A-code (Adv550), which does not distinguish between replies to queries and general commands, this only affects presence/absence of a blank line after the prompt line, and never before it. -d If using a data file, specify its directory. Ignored if the game is built as a simple executable with no associated data file. By default, the game data file is assumed to live in the same directory as the executable. The -d option allows a separate location to be specified. The program will attempt to work out the separator which should follow the directory name, but if in doubt as to the appropriate one for the given platform, the dbs name will be simply concatenated with the supplied pathname -- hence if it doesn't work, try adding the trailing separator to the pathname. [-r] Restore game from dump. Ignored if the game does not support game dump files being specified on the command line. The -r optional in that any command line argument which does not begin with a dash will be interpreted as the name of the dumpfile to restore on invocation. -c Replay game from log. This is a debugging tool, which allows a game to be replayed from a log file (see below). If the logfile contains more than one session log, only the first session will be replayed. The log contains the value of the random seed used in the session, thereby ensuring that the game is replayed exactly, despite any randomisation. [NB, replaying games only works if the log was created by exactly the same version of the game.] -l[] Log the game. Specifies the file into which a session log is to be written. The log is human-readable, but has some additional features allowing it to be used subsequently for replaying the session. If the nominated logfile already exists, it gets appended to. If no logfile is specified the name of the game is used, suffixed with .log. -u{off|on|none} -u{0|1|none} Set the initial state of undo-history collection. Ignored if the game does not support undo. If the value is zero, the default undo status is OFF. If the value is one, the default undo status is ON. The "none" state implies OFF and disallows undo functionality being subsequently switched on from within the game. The default state is ON for games which define the verb UNDO, and "none" otherwise. -B[] Force browser-based display, optionally nominating a particular browser. Browsers can be specified by their pathname, or by their name. -C Force console display, i.e. do not use the browser interface. -v Show the game, kernel and acdc version numbers and exit. -h Print command line usage summary. The following options are only meaningful in the console display mode, and therefore force the console mode even if the -B option is used. -o Set the output speed as specified by the argument. This option forces "dumb" mode console display (i.e. with no command editing) even if the browser display is explicitly requested via the -B option. Baud rate is specified in bits per second, and taking into the account control and parity bits, the output speed in characters per second is simply the baud rate divided by 10. The game coerces the specified baud rate to the nearest lower standard value (one of 110, 300, 600, 1200, 2400, 4800 and 9600), except that anything below 110 (the speed of a teletype) is also treated as 110. The default value is 300 -- the speed of a DECwriter. Note, however, that under DOS and Windows any baud rate above 600 results in no slowdown at all. -j[{off|on}] -j[{0|1}] Set text mode to wrap (0) or justify (1). If no value is specified, invert the default A-code setting for this game. In wrap mode, text is simply broken into lines according to the screen width (see the -s option below). With justification turned on, each line is right-justified. All of this presupposes a fixed font being in use. For variable font devices, which tend to do their own wrapping, the default screen width should be set to zero, meaning "infinite", and the margin should be specified as zero too. If no value is supplied, the effect is to invert the game's default setting. This option is ignored by games written in the "old style" A-code (i.e. by adv550). -s.[.] Set screen size (width in fixed font characters, height in lines, and margin in fixed font blanks). The default screen dimension is 80x24-1, the margin being set to 1 character. The -s option allows a different screen size (and optionally margin) to be specified. Screen width of zero means "infinite" width. Note that the line length cannot be set to less than 16 characters and the minimal number of lines per screen is 5. -p[{off|on}] -p[{0|1}] Pause on exit. Requests that after printing the final exit message the game should prompt the player for a , before exiting. This feature is intended for players who wish to play console version of the game, in a window which closes as soon as the game exits. The functionality of the -s, -u and -j options is also provided via kernel hooks (see procedure special() in the kernel source file adv00.c), so that the game may -- at author's discretion -- offer the player commands for toggling the justification switch, switching on and off the change history, and altering screen size and margin. Any unknown or suppressed keywords are quietly ignored. Mike Arnautov mla@mipmip/org 14 April 2013 ________________________________________________________________________
