- NAME
- egaint - Enhanced graphics aint
-
- SYNOPSIS
- egaint [cmp]
-
- DESCRIPTION
- Egaint is a particular two-dimensional variation of Tetris for the IBM
- Personal Computer domain.
-
- MACHINE REQUIREMENTS
- Egaint requires an IBM PC-AT, PS/2, or compatible 80286 or 80386
- machine; an EGA with 256 KB of RAM or a VGA; and at least 256 KB 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:
-
- c an IBM Enhanced Color Display (or any compatible device
- capable of displaying sixteen distinctive attributes at one
- time)
-
- m an IBM ECD-compatible device capable of displaying only two
- distinctive attributes at one time (i.e., "black" and
- "white")
-
- p an IBM ECD-compatible device capable of displaying only four
- distinctive attributes at one time (namely, the gas plasma
- display of the Toshiba T5100 Portable Personal Computer)
-
- 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 twelve). 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 Space (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.
-
- 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 shadow,
- 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) and for, naturally, clearing rows.
- 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.
