NAME
xbubble - an X Window based puzzle bubble clone
SYNOPSIS
xbubble [OPTION]
DESCRIPTION
XBubble is a Puzzle Bubble (PB) / Bust-A-Move (BAM) clone for Unix/X11 platforms. It was written from
scratch with no real intent to exactly reproduce the original game.
OPTIONS
-d DISPLAY
Set X display to DISPLAY.
-s <scale>
Set game window size (between 5 and 100). The game window size is normally automatically scaled
to your screen size. This option is useful to reduce load on slow/loaded systems. See also the -f
option.
-f <framerate>
Adjust frame rate (in frames per second). Usual values are 100 (default), 50, 33, 25, etc. The
actual frame rate may be different from the one you specified, depending on system timer
resolution. You can use this option to reduce load on slow/loaded systems (e.g. if sprite
animation is jerky). See also the -s option.
-r <resource path>
Tell XBubble to look for its graphics files, fonts, etc. in directory <resourcepath>.
-t <theme name>
Use the given theme (possible values are: plain, frozen, fancy).
PLAYING
The goal is to clear all bubbles from your board and avoid bubbles dropping below the line at the bottom
of the screen. You can rotate and fire a canon that launches colored bubbles. Bubbles bounce against the
walls until they get stuck to another bubble. If you get three or more adjacent bubbles of the same color
they all explode, while any bubble left hanging free falls down.
In single player mode, the ceiling goes down every 12 launches so that you must clear the board before
the ceiling touches the ground.
In multi-player mode, the ceiling does not move but a fresh row of bubbles is added on top of the board
while all bubbles are lowered by one row. Additionally, each time you explode three or more bubbles, all
extra bubbles are sent (with random colors) to your opponent, as well all falling bubbles. You win the
round when your opponent loses (has bubbles dropping across the bottom line).
After a few seconds delay, your canon launches its bubble anyway. You can tune this delay when selecting
your handicap. The higher the handicap, the shorter the delay.
GAME CONTROL
The game is entirely controlled using the keyboard:
Player 1
Left arrow / Keypad 4 = Rotate canon left
Right arrow / Keypad 6 = Rotate canon right
Up arrow / Keypad 5 = Launch bubble
Player 2
x = Rotate canon left
v = Rotate canon right
c = Launch bubble
General
Up arrow / Keypad 8 = Menu navigate up
Down arrow / Keypad 2 = Menu navigate down
p = Pause
Escape / q = Abort
There is no command-line option for changing control keys yet.
PLAYER VS COMPUTER MODE
You can choose between 5 levels of difficulty. Beware of the highest level if you have a slow machine,
as it is quite CPU consuming.
