NAME
XBlast - Multi-player "Blast the Others" game
SYNOPSIS
xblast [ [player1]@[display1] [player2]@[display2] ...]
DESCRIPTION
XBlast is a multi-player arcade game for X11R5/R6. The game can be
played with at least two players and up to six players. It was
inspired by the video/computer game Bomberman(Dynablaster), which was
to my knowledge first programmed for NEC's PC Engine/Turbo Grafx.
Other (commercial) versions of the original game exist for IBM-PC,
Atari ST, Amiga, NES, GameBoy and Super NES.
PLAYER SETUP
If you never have started xblast before, take a look at the section
LAUNCHING XBLAST below.
In order to setup XBlast via command-line you have to define the
players and their according displays first. The player setup can only
be omitted when loading the default or a named setup (using -D or
-D=setup). The players have to be the first command-line arguments
given to xblast. They can be given in one of the following formats
playerName@displayName
This defines a player named playerName using the display
displayName.
playerName
As above, but the player will be using the default display, i.e.
the one defined by the environment variable DISPLAY or by the
option -display.
@displayName
This defines a player at the display displayName. The player name
will be taken from internal defaults or from the X-Resources (see
below).
@ As above, but the player will be using the default display, i.e.
the one defined by the environment variable DISPLAY or by the
option -display.
If two players have the same displayName (or both of them none at
all), they will be playing in the same window at their display
displayName. The first player given will be using the number pad for
control, while the second player will use alphanumeric part for
control. There can be only one or two players at one display.
TEAM MODE OPTION
Since version 2.2 XBlast features several team modes, allowing players
to cooperate:
- 1 - Formatted: October 24, 2025
xblast(1) xblast(1)
Release 2.2 (December 14th 1996)
-single
In this mode each players plays for himself, .i.e the team mode
is disabled. It is also the default setting.
-team
In this mode two players work together as one team. The players 1
& 2, 3 & 4 and 5 & 6 each form a team. In order to win, only one
player of a team has to survive. This mode only works with 4 or 6
players.
-double
This mode is still experimental. Each team consits of two players
at one display, where both player sprites have the same name and
colors. A two-team-game must be setup like a two-player-game
with option -double. The same for three and four player games.
SOUND OPTIONS
These options are only valid, when XBlast was compiled with the
optional Linux sound support.
-stereo
This enables the stereo sound support for XBlast. This is the
default option.
-mono
This enables the mono sound support.
-nosound
This disables the sound support.
OTHER OPTIONS
The program XBlast supports the following command-line options besides
the player setup. With the exception of +u and +U options beginning
with a `+' restore a setting to its default. This is useful for
modifying loaded setups or X-resources.
-display
This option specifies your display. This display is used for all
players, where a display name has been omitted (see above).
-?, -h
This option causes XBlast to print a usage message.
-bw The option forces black and white mode for all displays.
+bw The option indicates to allow the color mode for all displays,
which support it.
-D This option indicates to load default settings from the file
".xblast" in your home directory. This save file will be used by
the Tcl/Tk based launcher in the package.

Release 2.2 (December 14th 1996)
-D=setup
This option indicates to load the game setting named setup as
default. The setup is loaded from the file setup in the
directory ".xblast-setups" in your home directory.
-f number
This option sets the frame rate to number frames per second. The
default value is 20.
-F The options disables the fork mode. Only one process is running
now. +F This option causes XBlast to fork and run one process
for each display. Very useful if you are playing on XTerminals
connected to a fast server.
-L number
This option sets the number of lives per player to number. The
default value is 3.
-l levelID
This option sets the starting level to levelID The option -l is
ignored when using random level order. Use -s to determine the
levelID of all levels available.
-q The option turns off bell sound.
+q The option turn on bell sound.
-r The option sets the random mode for level order and player
position on. This option does not override the options +rp and
+rl or the equivalent resources.
+r The option sets the random mode for level order and player
position off. This option does not override the options -rp and
-rl or the equivalent resources.
-rl The option turns on random mode for level order.
+rl The option turns off random mode for level order.
-rp The option turns on random mode for player positions.
+rp The option turns off random mode for player positions.

Release 2.2 (December 14th 1996)
-s The option forces XBlast to print a list of all levels. The list
contains the level ID, its name and author.
-u levelID [levelID ...]
The option indicates to use the levels given by levelID for
playing. levelID can either be the id of a single level or a
interval of ids as levels already selected in a loaded setup or
X-resource. This option is useful to add levels to a loaded
setup (see -D, -D=).
-U levelID [levelID ...]
The option indicates to use the levels given by levelID for
playing. Any level not given in that list will not be played.
This option is useful to override any level selection form a load
setup (see -D, -D=).
+u levelID ...
The option indicates to ignore any level given by its levelID for
playing. These option removes the given levels from the
selection. It can be used to remove levels to play from a loaded
setup. (see -D, -D=).
+U levelID [levelID ...]
The option indicates to ignore any level given by its levelID for
playing. These option removes the given levels from the
selection. Any level not given will be selected to play. It can
be used to override loaded setups. (see -D, -D=).
-v number
This option sets the number of victories to win game to number.
The default value is 5.
-wm This options allows XBlast to override the reparent request by
the window manager, i.e. the XBlast windows will not be managed
by the window managers. This may speed up performance on some
systems.
+wm This options allows the XBlast windows to be managed by the
window manager.
LAUNCHING XBLAST
The easiest way to start XBlast is to use tkXBlast(1) The second
easiest way to launch XBlast is to start it without any command-line
arguments. Then XBlast runs an interactive game setup querying for
players and game parameters.
Since it faster to launch XBlast using command-line arguments, some
examples are given here. A detailed description of all command-line
arguments is given in the sections PLAYER SETUP and OTHER OPTIONS (see
above).

xblast(1) xblast(1)
Release 2.2 (December 14th 1996)
In the first example xblast is invoked for two players (named Olli and
Rodi) at one display, the default display. The default display's name
is taken from the environment variable DISPLAY.
$ xblast Olli Rodi
In this example defaults are used for all settings, e.g 3 victories
needed to win the game, 3 lives per player.
If Rodi is using his own X-terminal (or workstation) X25, use
$ xblast Olli Rodi@x25:0
Do not forget that the player Olli needs access permission to the
display of player Rodi. This can be achieved by using xhost. If
XBlast is started on the host hamlet, Rodi must type
$ xhost hamlet before XBlast is started.
If you want for more players to join the fun, use for example
$ xblast Olli Andreas@x09:0 Rodi Harald@x25:0
Now Andreas is the second player playing at x09, Rodi is the third,
playing together with Olli at the default display. Harald is the
fourth player using x25.
If you want to play in team mode, i.e. Olli and Andreas vs. Rodi and
Harald, do the following:
$ xblast Olli Andreas@x09:0 Rodi Harald@x25:0
To make the things complicated let's add some game options. Here only
Olli and Andreas are playing, but with 6 victories needed to win the
game:
$ xblast Olli Andreas@x09:0 -v 6
If you also want random starting positions for each player, type
$ xblast Olli Andreas@x09:0 -v 6
To play also the levels in random order, type
$ xblast Olli Andreas@x09:0 -v 6
or
$ xblast Olli Andreas@x09:0 -v 6
which turns all random order options on.
Next case, you don't like some levels, e.g. XBlast 2000. To exclude
it first type
$ xblast -s | grep XBlast 2000
to get the ID of the level XBlast 2000. In the current version it is
3. Thus type
$ xblast Olli Andreas@x09:0 -v 6
But if you only want to play only some levels (e.g. Shrinking World
and Full Power Level), type
$ xblast Olli Andreas@x09:0 -v 6
Alternatively, if you also want to play levels 5 to 8, you can either
type
$ xblast Olli Andreas@x09:0 -v 6
- 5 - Formatted: October 24, 2025
xblast(1) xblast(1)
Release 2.2 (December 14th 1996)
or
$ xblast Olli Andreas@x09:0 -v 6
Since setting up XBlast from scratch is a bit unhandy, let's save the
setup. In order to save the above setup, use
$ xblast Olli Andreas@x09:0 -v 6
To start XBlast again with the same setup, just type
$ xblast -D
If you want to save several different setups, use a named setup, e.g.
if you want to save the above settings as afterLunch, type
$ xblast Olli Andreas@x09:0 -v 6
and
$ xblast -D=afterLunch
to restore it.
You can also modify a loaded setup, e.g you want to play with only 2
lives per player, then type
$ xblast -D=afterLunch -L 2
If you also want to change the levels to play, you can add or delete
levels from the setup (using -u or +u), or you can create a new list
(using -U or +U). Example: if you want to play the level Seek'N
Destroy in addition to the above setup, type
$ xblast -D=afterLunch -L2 -u 0
If you type instead
$ xblast -D=afterLunch -L2 -U 0
only the level Seek'N Destroy will be played.
Last but not least to save your modified setup, e.g as afterTea use
$ xblast -D=afterLunch -L2 -u 0
PLAYING XBLAST
The idea of the game is quite simple "There can be only one ...". So
the aim is to blast away all the other players. Use your bombs to
blast away the other players and certain blocks (e.g. the ?-Blocks in
the 1st level). Under some of these blocks are extras.
The following keys control the first (right) player at one display
KP_8, KP_Up
player starts walking up.
KP_2, KP_Down
player starts walking down.
KP_4, KP_Left
player starts walking to the left.
KP_6, KP_Right
player starts walking to the right.

F player starts walking to the left.
H player starts walking to the right.
G player stops (in the center of the next block).
Space
player drops a bomb (in the center of the current block).

A request to abort of level.
Z cancel abort request.
A single player can use both key sets for playing. Furthermore the
following keys effect all players
P pause game, resume game after pause.
Escape
quit game immediately.
Please not, since XBlast 2.2 the keybindings can customised via
XResources (see also PLAYER RESOURCES and tkXBlast(1)).
EXTRA SYMBOLS
There are many extras to be found in xblast. Most of the time they can
be found under blastable blocks, sometimes they are just lying around.
The following extras can be found in nearly any level. You will keep
these extras until you have lost all your lives or the level ends.

Bomb (red frame)
This extra increases the number of bombs you can drop by one.
Flame (yellow flame)
This extra increases the range of your bombs by one field.
Furthermore in several levels the following symbol can be found
Skull (cyan frame)
This is not really an extra, but you will be infected with an
random illness when picking it up. You will be healed
automatically after a certain time, or if you loose one life.
Additionally you can infect other players while being ill.
In many levels there is also a special extra. There will always be
only one type of special extra per level and you will loose it if you
loose a life. The following special extras can be found
Kick extra (moving bomb in blue
This extra enables you to kick bombs by running into them.
Invincibility (star in golden frame)
This extra makes you invincible for some time. You are not killed
by explosions, stunned by moving bombs, nor infected by skulls.
Global Detonator (button in deep pink
Picking up this extra ignites all bombs on the map. Use with
care.
Construction Bombs (bricks and bombs in
This extra gives you construction bombs as special bombs. These
bombs create a blastable block when exploding. Use the special
key to drop them.
Remote Control (button box in spring
This extra enables you to ignite all your bombs, by pressing the
special key.
Teleport Extra (beaming player in orchid
This extra enables you to beam away to a random location. You
must be in the center of a block to activate it. Use the special
key to teleport.
Airpump (clouds in sky blue frame)
This extra enables you to blow away (not to blast away) bombs
within a range of 2 fields. It also works when your are trapped
between two bombs. Use the special key to activate it.
Napalm Bombs (burning bombs in orange
This extra allows you to drop a high powered napalm bomb using
the special key. This bomb has a much larger explosion than
- 8 - Formatted: October 24, 2025
xblast(1) xblast(1)
Release 2.2 (December 14th 1996)
normal, and is bigger if you have more Flames. If the bomb is
struck with an explosion, it will explode as a normal bomb. For
the large explosion to occur, it must explode on its own.
Firecrackers (firecrackers in orange frame)
This extra allows you to drop firecracker bombs with the special
key. Firecracker bombs set off a series of explosions that can
clear away a small area. One in ten firecracker bombs is high
powered, and clears away a much larger area. There is no way to
tell if a firecracker is high powered or not until it explodes.
Unlike napalm bombs, there is no way to stop the firecracker
explosion, although it is blocked by walls and other solid
objects.
Pyro bombs (firecrackers in orange frame)
This extra allows you to drop pyro bombs with the special key.
Pyro bombs explode with a series of small explosions that dance
around the level. These explosions are blocked by walls and other
bombs, but are able to travel through corridors with ease. They
explode randomly and cannot be controlled. Pyro bombs have the
same range irrespective of how many flame extras you have. Even
if the bomb is struck with an explosion, it will still explode as
pyro bomb.
Junkie Virus (syringe in yellow green
This extra infects you with the junkie virus. Whilst you have the
junkie virus, you are randomly infected with illnesses (as if you
were picking up skulls). You MUST touch other players to pass on
the illness within a certain time limit or you will lose a life.
Any touched players are given the junkie virus as well. There is
currently no way to get rid of the junkie virus (but look for a
rehabilitation centre in the next release). :)

out of the window and inside again.
Some levels lack a description.
If you alter the players of a loaded setup, you may get surprising
results, when defining players without a given display name (see
