DESCRIPTION
Xbl is a game involving dropping blocks like Xtetris but in 3 dimen‐
sions. As they drop you can move them with numeric key pad (if you
have), cursor key or rotate other 3 axis in 2 directions (6 other
keys). Space key for dropping quickly and 'p' key for pause. All the
possible keys are displayed in menu window.
Points are scored for each block that comes to rest on the gradually
building up pile of blocks. When the pile reaches the top of the
screen and no further blocks can be dropped the game ends. When a stage
of blocks across the 3D matrix is completely filled, that stage is
removed and all the blocks above are dropped down. As more stages are
deleted the blocks fall faster.
There is one high score table by size of matrix and pieces types.
For your information, another 3D tetris exists, its name is spatial. A
sphere packing game also exists; its name is spheral. For these two
games, contact Andrew Plotkin ( ap1i@andrew.cmu.edu ) or you can
retrieve the file threedee.tar.Z somewhere in the world...
An enhanced HTML version of this manual is in our computer (in the same
directory than scores). If you can't find it, use the networked ver‐
sion: http://www710.univ-lyon1.fr/ftp/xbl/xbl-man.html
OPTIONS
The next options can only be set when the game starts.
-display hostname:0.0
Gives the display name.
-geometry geometry_string
-scoregeometry geometry_string
-zoogeometry geometry_string
-menugeometry geometry_string
Gives the geometry of the play, score, zoo and menu window.
-help Displays the options, possible values and current values.
-verbose
Displays various things for debugging.
-colormap
Creates its own colormap even if unnecessary.
-visual
On screen with multiple visual, it search the best one to use.
In this case it does not use the default visual.
-bw Displays in black and white even on color display.
-buffer 0...5
Chooses the buffering method for animation. Each method uses
resources. Speed of buffering method is hardware dependent.
Perfect methods are 2,1 and 3, choose the fast one.
-font font_name
Chooses font for menus, score window...
-bigfont font_name
Chooses a big font for menu (the score and high score)
-buttonheight -1...16
The height of 3D buttons. If your display is slow use small
button. The -1 choice is half the height of the font.
-color 0...6
Background color for menu window.
0:Black
1:Red
2:Green
3:Yellow
4:Blue
5:Magenta
6:Cyan
-sync Uses X Synchronise. Only for debugging.
-clearline 0...1
If 0, clears line with rectangle filling; otherwise with a black
line. It's useful with some X servers that don't draw the same
segment with the same pixels. Another method to avoid this prob‐
lem is to use a linewidth equal to 1, though in this case draw‐
ing is slower.
-linewidth 0...16
Thickness of the moving block lines.
-fps 1...100
Number of frames by second. If it is set too high, the display
might be jumpy. If set to 0, the game runs at maximum speed.
-time_to_demo 1...999
Number of seconds before the automatic demonstration.
-speedtest
This option helps you to find the fastest buffering mode.
-stat Statistics on launched blocks, they are displayed at the end of
the game.
-keytable keys_list
A 19 characters list in the order (D=Down L=Left R=Right U=Up) :
Translations:DL,L,UL,U,UR,R,DR,D
Rotations: RX+,RX-,RY+,RY-,RZ+,RZ-
Others: LaunchBloc CancelGame SuspendGame QuitGame
Drop1Level
Don't forgot ' if there are special characters.
Next options can be changed while game is running.
-keyboard 0...5
This switch chooses keyboard type :
0:Use key table, given by -keytable
1:AZERTY|
2:QWERTY|
3:AZERTY-
4:QWERTY-
5:SPATIAL
SPATIAL is the set of keys of the other 3D tetris : spatial
-zoo Displays the zoo (all possible pieces) when game starts.
-score Displays the score table when game starts.
-draw 0 or 2
Draw mode. 0 for wire frame piece and 2 for transparent pieces.
On slow host, 0 is necessary.
-x 3...8 -y 3...8 -z 6...18"
World size : width, height, depth.
-smooth
Starts game with smooth drawing.
-training
In this mode, pieces don't fall. By the way scores are not
saved.
-shownext
Next piece is shown. By the way score are multiplied by 0.7
-level 0...10
Level 0 is slow, 10 is unplayable. This option chooses the
starting game level. Level game increases during game.
-bloctype 0...2
0 : Only flat pieces.
1 : Some 3D pieces.
2 : All possible pieces with less or equal than 5 cubes.
-land 0...2
0 : Small land (3x3x15)
1 : Big land (5x5x10)
2 : User land (as defined by options)
-eyedistance -1...1
If not 0 the game is with real 3D. But you need to cross-eye (or
the opposite). The value is positive if your right eye look the
left image et the left eye look the right one. Indicate a nega‐
tive value to swap the two images.
FILES
/usr/local/lib/xbl
Directory which contains the score tables and COPYING file (FSF
GPL)
/usr/lib/X11/app-defaults/Xbl
Defaults for Xbl, this file only contains a data: the option
line for Xbl.
xbl*args: -x 5 -y 5 -z 10 -level 0 \
-bloctype 2 -land 0 \
-draw 2 -smooth -buffer -1 \
-keyboard 4 \
-keytable '14789632azqswx ^[p^C0'
ENVIRONMENT VARIABLES
XBLOPTIONS
Xbl will search his options in this variable, you can put :
XBLOPTIONS='-smooth -draw 0' export XBLOPTIONS
in your .profile or .login file.
BUGS
If sometime a block fall multiple level at once it indicates that your
fps is set too high.
SOUND isn't correct on some X server, no possible correction.
FLICKING DISPLAY on some X server that doesn't handle XSync correctly.
You can turn around using : -buffer 2
DIRTY POINT on screen because some X servers don't draw the same pixels
for the same segment. You can turn around using : -clearline 0 or
-linewidth 1
FOCUS WINDOW doesn't work with OpenWin, so put the cursor in the game
window.
DEMO mode seems to cheat (blocs going through other blocs) but it is
because the visualization show a direct way (it sums all the transfor‐
mations up). In fact, the real way could use very complex and tortuous
indirect path.
