This is the first game on the Z88 that uses the graphics area. Since no
documentation were available in the Developers' Notes, we had to figure
it out our selves. All the graphics routines (plotting, line drawing
and sprite movement) have been included in our standard library which
is supplied in the Z88 Assembler Workbench. You will then have all the
possibilities to exploit graphics for your own application purposes.
The game is based on the popular russian version which in our
implementation also uses a larger playing area (configurable), and also
uses an 'extended' set of blocks. The standard blocks are build of 4
brick entities. Our extended blocks are build of 5 brick entities.
Three game types are available: standard game (as the original russian
version), extended game (using standard and extended blocks) and
advanced game (using only extended blocks).
You may configure the movement keys, the size of the playing area, the
block rotation direction, the default speed movement and toggle the
"next block display" feature.
Finally a high score list is implemented for each game type.
%H2%%H4%Installing the ZetriZ game application card%H4%%H2%
Activate the INDEX popdown (pressing #I or the <INDEX> key), open the
flap and insert the card in one of the available slots. When completed,
close the flap, and you will see that the INDEX updates its windows.
Using the <UP> or <DOWN> cursor keys in the "Applications" window will
reveal a new application named "ZetriZ" that uses the #Y hotkey.
%H2%%H4%Activating the ZetriZ application%H4%%H2%
ZetriZ has been programmed as a "good" application. It uses only 336
bytes workspace and appropriate dynamic memory for the high score
tables. Several instantiations of ZetriZ may be created. Since ZetriZ
uses a map area of 256 pixels it is only possible to play the game on
extended Z88 computers (128K RAM or more in slot 1). The ZetriZ
application is automatically aborted if activated on a standard 32K Z88
computer. Anyhow, who is using a 32K version these days???
The application is activated by pressing an initial #Y hotkey or
pressing <ENTER> on the "ZetriZ" name in the Applications window in the
INDEX. If several ZetriZ games are created you will cycle through them
when using the #Y hotkey.
%H2%%H4%The High Score Table file%H4%%H2%
The high scores and game configuration information are preserved in the
":RAM.0/ZetriZ.dat" file. When the ZetriZ application is created,
ZetriZ will automatically load the high score and configuration
information from the file. If the file is not available, no high scores
will be present (ZetriZ has been activated the very first time), and a
default game configuation will be used. A high score table is available
for each of the three game types (standard, extended and advanced).
The high score tables and game configuration are only saved to the
":RAM.0/ZetriZ.dat" file when ZetriZ is KILL'ed from the INDEX. If you
soft reset the Z88 using the PURGE command from INDEX or pressing the
soft reset button, the high score information in the game will be
released back to available Z88 memory - and not stored into the high
score file. When the current high scores are updated to the
":RAM.0/ZetriZ.dat" file, they are actually merged with the file
contents. This assures that you always get the all-time-best scores,
even though you have several ZetriZ applications running which sooner
or later is KILL'ed from the INDEX.
If you want to preserve your score and configuration information, make
a backup on a file EPROM or transfer it to another computer using the
EasyLink software. Should a hard reset occur, you will otherwise
have lost your high scores.
%H2%%H4%The High Score Tables in the game%H4%%H2%
There are three high score tables available, one for each game type
(standard, extended, advanced). The current high score table displayed
will reflect the last game played, ie. having played an extended game
will display the high scores of the extended game played when ZetriZ is
running the main game menu. Each high score table has 6 entries; the
top entry is the best score - the bottom score is the lowest. Each
score contains a name (max. 12 characters), the total number of lines
removed, the total number of blocks played and the date of the score.
The following is an example of a high score table:
___________________________________________________________
%H2%High Scores, Standard Game%H2%
%H4%NAME%H4%
TheBest
gbs
fred
gbs
erling
hugo
___________________________________________________________
You may only have individual scores - no identical scores is allowed.
Scores are always inserted into the table, ie. inserting 5200 into
the above table will put it into a 3rd place - the scores below will
automatically be adjusted downwards. The previous bottom score "falls"
out and is automatically removed from the list. There are always 6
scores or less in a score table.
%H2%%H4%The Main Menu%H4%%H2%
When a Zetriz application is created the main menu is displayed
together with the game window (the map area). When a game has finished
you will also move back to the main menu. The current high score table
and the game window are toggle-displayed each 15 seconds if no keys
are pressed. Pressing a key automatically toggle-displays the
appropriate windows. ZetriZ may be suspended any time (by activating
another application. The current ZetriZ window contents is always
re-drawn when you enter ZetriZ.
The main menu consists of three items:
<1>
<2>
<3>
You select an item by pressing the appropriate number enclosed by the
<> symbols.
%H2%%H4%Playing a game%H4%%H2%
Choose item <1> in the main menu. A sub-menu is displayed:
<1>
<2>
<3>
Choosing <1> will play a standard ZetriZ game using 4 brick entity
blocks. Choosing <2> will play a game containing both the standard and
extended blocks. Choosing <3> will play a game containing only the
extended blocks, which is pretty tuff for the brain!
When you have chosen the menu item the game begins. The game window is
reset, and a text is displayed in the menu window which informs the
player which keys to use for block movement.
When ZetriZ is started for the first time, the following keys are
defined:
Q
Z
S
A
<TAB>
<ESC>
%H2%%H4%How to play%H4%%H2%
The aim of the game is to assemble the falling blocks into horisontal
lines. When a line is filled, ie. a straight horisontal line of bricks,
it will be removed, followed by a scroll of the pile of the above
blocks into the place of the removed line. You have to continously
remove the blocks by assembling lines (to remove them) otherwise the
blocks will gradually pile up and block the entrance of a new block. If
an entrance of a new block fails due to a collision, then game is over.
If the accumulated score is among the six best then you are asked to
enter your name for the new score, which will be inserted into the
score list.
%P0%
%H2%%H4%Suspending the game%H4%%H2%
If you want to suspend/pause the game, press <ESC>. Pressing <ESC>
again will abort the game. If your score made it to the high score
table you will be asked to enter your name.
ZetriZ have been properly interfaced with OZ to allow task switching
both during the main menu and during playing of the game. If you press
<INDEX> or another application hotkey, ZetriZ will be suspended and the
appropriate task will be entered. When you re-enter ZetriZ, the windows
will be re-drawn and the game continues. If you want to avoid a
confusing re-entry since the game just continues, pause the game with
<ESC> before leaving ZetriZ. When you re-enter at a later time, ZetriZ
will still be in pause mode.
%H2%%H4%Configuring the block movement keys%H4%%H2%
To configure the block movement keys, menu item <2> in the main menu
must be selected. Then requests are displayed to press a key for each
corresponding movement. If no key is pressed, the current setting for
that key will be used (nothing is altered). The current block movement
keys are displayed in the text window during playing of the game. When
the game begins, press <ESC> to pause the game. Place your fingers at
the keys according to the movement and then press any key to continue.
The key definitions are also saved in the ":RAM.0/ZetriZ.dat" file.
%H2%%H4%Defining the auto repeat response%H4%%H2%
You may use the autorepeat feature to quickly move a block in the
specified direction. The timeout value to activate auto repetition is
defined in the Panel at the "Auto Repeat Rate" option. If you set this
option to 0, there will be no auto repeat in the game.
%H2%%H4%Changing the block rotation direction%H4%%H2%
The initial direction for rotating the block is anti-clockwise, ie.
leftward rotation. You can toggle the rotation clockwise/anti-clockwise
by issuing item <3>, "Change game parameters", in the main games menu,
followed by item <1>, "Change Block Rotation Direction" in the
sub-menu. This parameter is also stored in the ":RAM.0/ZetriZ.dat"
file.
%H2%%H4%Changing the ZetriZ map size%H4%%H2%
The ZetriZ map is initially set to 23 lines deep. You may change this
by adding bricks from the bottom and upwards, reducing the total space
available for moving a falling block. This is useful if you want to
train movement on a smaller playing area. Select item <3>, "Change game
parameters", in the main games menu, and item <2>, "Change ZetriZ map
size". To add a brick line press <P>, to remove a brick line press <O>.
You can add maximum 15 lines. When you have inserted the number of
lines, press <ENTER> to finish. This parameter is also stored in the
":RAM.0/ZetriZ.dat" file.

and
During the game the speed is automatically increased each modulus 10000
points. If you already have speed 7 and reach another 10000 points, the
speed will automatically wrap back to 0. Altering the initial speed is
good when you want to practice playing at high speeds.
The initial block movement speed parameter is saved in the
":RAM.0/ZetriZ.dat" file.
%H2%%H4%Toggling the Next Block feature%H4%%H2%
During the game you may see the next block to be inserted into the
game. This is a benefit, since you can plan ahead to place the blocks
strategically. You may toggle this feature off - which makes the game a
bit more difficult. Select item <3>, "Change game parameters", in the
main games menu, and item <4>, "Toggle Next Block Feature". The Next
Block feature parameter is also saved in the ":RAM.0/ZetriZ.dat" file.
%H2%%H4%ZetriZ Game Points%H4%%H2%
During the game you are given 10 points for each new block inserted
into the game. Additionally, the following table lists the points
for removing lines:
Removing several lines means that you actually inserted a block that
filled several lines simultaneously.
That's all. Have fun.
