VThe game Shapes is based on the arcade game tetris, and follows roughly the sa
Xme
Xrules, Full instructions are given in the game itself.
X
VThe game requires a VT100 compatible terminal, and a VAX running VMS version 4
X
Xor later (at any rate, 4 was the earliest version it was compiled under).
X
XThe source code consists of:-
X
X Shapes.pas - The main source code for the game
X
X Includes.c - Certain system calls, which were easier to write in 'C'
X
X Rand.for - Random number generator, written by a friend, Stephen
X Macdonald, and borrowed by me, cos I couldnt be bothered
X
X
XSetting up the game:-
X
XThe game shapes uses 2 data files, one for the high score table, and one for
Xany saved games which might exist. The destinations of these files should be
Xchanged in the source code "Shapes.pas" to point to wherever you want the
Xfiles.
X
XThe actual lines to change are:
X
X Htablefile='disk18:[cadp02.pascal.shapes]Htable.dat';
X Savefile='disk18:[cadp02.pascal.shapes]save.dat';
X
X
XTo compile this code, execute the command procedure "compile.com" which is
Xsupplied with this archive (e.g @compile )
X
XAfter compiling the code you need to create 2 empty data files, one for
Xthe saved games, and one for the high score table.
X
XThis is done from within the game itself, by entering the "Cheat" mode.
XTo do this, run the game, and when the menu comes up, type in the string
X"cadp8". This activates the cheat mode.
X
XYou are then asked for a level number. This would be what level you would
Xlike to start at, if you were going to play the game. At the moment we
Xare not interested in that, so type 1 and press return.
X
XYou are now prompted if you would like to reset the saved games file.
XPress y and return.
X
XDo the same for the highscore table file.
X
XBoth files should be on world read and write access if other people are to
Xbe able to play the game.
X
X
XThe game is now ready to play.
X
X
XNotes on the cheat mode:-
X
XBy entering the cheat mode as above, you can reset either , both or none of
Xthe data files for the game, and choose which level to start on. Also,
Vfrom within the game you can choose which shape you would like next by pressin
Xg
Xthe keys 1 to 7 to choose. The appropriate shape will appear in the next shape
Xposition.
X
X
XThats it!! Enjoy!!
X
X
XYou are free to modify the code in any way whatsoever.
XThere are probably major improvements that can be made in the game as it is,
Xso if you make any, or have any comments, mail them to me at:-
X
X "CADP02@uk.ac.strath.vaxe"
