NAME
egaint - Enhanced graphics aint
SYNOPSIS
egaint [bcmp]
DESCRIPTION
Egaint is a particular two-dimensional variation of Tetris for the IBM
Personal Computer domain.
MACHINE REQUIREMENTS
Egaint requires an IBM PC, PS/2, or 100% compatible machine (an 8 MHz
or faster CPU is strongly recommended); an EGA with 256k RAM, VGA, or
Hercules graphics adapter; and at least 256k free system RAM.
OBJECTIVE
To construct as many contiguous rows as possible by manipulating (via
both rotational and translational motion) variously shaped blocks
which are randomly dropped from the top of the screen. Play ends when
the resulting structure reaches the top of the screen.
COMMAND-LINE OPTIONS
Egaint accepts one option specifying what sort of display device is
present:
b an EGA or VGA in color mode connected to a black-and-white
display device
c an EGA or VGA connected to a color display device
m an Hercules or EGA in monochrome mode connected to a monochrome
display device
p an EGA or VGA connected to a four-shade gas plasma display (i.e.,
the Toshiba T5100 Portable Personal Computer)
If no option is specified, egaint will assume (if no configuration
file exists in the working directory) either the color display (option
"c") or whichever option is specified in the configuration file (see
below).
GAME OPTIONS
Once inside egaint, several game options are available, all of which
will be summarized below.
Tournament Game
allows players to compete against each other by providing
for reproducible games; a particular tournament game will
play exactly the same each time it is invoked. Note that
all conditions must be identical for games to be identical
(i.e., the same version of egaint, the same initial level,
etc.).
Tournament Game Number
specifies which of the 256 possible games to play.
Initial Level
where one is the easiest (slowest) and eleven is the hardest
(fastest).
Initial Height
specifies how high (in blocks) an area should be filled with
randomly placed blocks (ranges from one to nineteen). This
value will be adjusted should the pit depth minus the
initial height value be less than five. Hidden blocks are
(as the name connotes) invisible.
Show Next
toggles whether or not the next shape to be put into play
should be displayed in the window in the upper-left corner
of the screen.
Extended Shapes
determines which particular set of shapes should be used
during play. Classic (the seven basic shapes) is a subset
of Easy, Easy is a subset of Medium, and Medium is a subset
of Hard.
Block Style
for aesthetic reasons, specifies which particular set of
graphic blocks should be used to represent the shapes in
play.
Key Binding
determines which keyboard binding set is to be used during
play; in the following descriptions, the keys are given as
follows: (1) move left, (2) rotate counter-clockwise, (3)
move right, (4) rotate clockwise, and (5) drop.
Classic J I L K Space
Russian J K L I Space
Berkeley H J K L Space (UNIX vi-style)
Left-handed S E F D Space
Finnish S D F E Space (Left-handed Russian)
San Francisco A S D F Space (Left-handed Berkeley)
Arrow 4 8 6 5 0 (number pad)
User-defined allows the user to define the key bindings;
these key bindings will remain in effect
until the Key Binding option is changed, at
which the defined bindings will disappear.
In addition, the specified key bindings will
be saved in the configuration file if this
binding is still active upon exit to the
operating system.
Pit Depth
determines the depth of the pit in rows (ranges from five to
twenty-four).
Show Guide
toggles whether or not guide rulers should be displayed in
the pit.
OTHER KEY BINDINGS
The following bindings are also in effect no matter which key set is
chosen:
Escape when first hit, pauses play: if hit again while paused,
aborts play; otherwise, play resumes. Pressing Escape
during while selecting options will exit the user to the
operating system.
Ctrl-B cycles the current block style
Ctrl-L increments the current level
Ctrl-N toggles show next
Ctrl-S toggles sound effects
Ctrl-X cycles the current shape set
Ctrl-\ quick exit to the operating system
SCORING
Each shape has been assigned a point value based on its difficulty of
placement and frequency of necessity. This value is first multiplied
by the current level and then incremented by the relevant bonuses
(bonuses are awarded for not using show next, not using show guide,
having an initial height, etc.). The point value for the current
shape is displayed within the score window next to the "value"
heading.
In addition, points are awarded for dropping pieces (the higher the
drop, the greater the points), clearing rows, and having an empty pit.
These points are also multiplied by the current level and incremented
by the relevant bonuses.
LEVEL ADVANCEMENT
The rule for level advancement is as follows: after the xth row is
cleared and if x is a multiple of ten, current level will become n,
where n=(x/10)-1 (if n is greater than the current level). However,
the attainment of level eleven will only occur after clearing 200 rows
(rather than the expected 100 rows).
CONFIGURATION FILE
Egaint will save the current options (upon exit to the operating
system) in a file in the current directory called EGAINT.RC; the
format is pretty self-explanatory upon inspection. If egaint cannot
find its configuration file in the current directory, it will create
one with its default options.
HIGH SCORE RECORD
Egaint will save the top fifteen high scores in a file in the current
directory called EGAINT.REC. Again, if egaint cannot find its high
score record in the current directory, it will create one.
