SYNOPSISxinvaders [-all_those_groovy_xtoolkit_switches]
DESCRIPTIONxinvaders is an implementation of the old Atari Space Invaders game, on
top of the X11 window system.
PLAYING XINVADERS
The game will start with all the invaders drawn. Press 'p' to play,
and you're off, or use the newly provided buttons.
The controls are:
z Fire a shot. You will only be able to fire one shot at a time,
so be careful.
, Move left. Pressing this key will start you moving to the
left, releasing it will make you stop.
. Move right. Pressing this key will start you moving to the
right, releasing it will make you stop.
p Pause or Play. Pressing this will either pause the game, or
play it. Remember, you must press it to start the game (either
at the very beginning, or between new games).
q Quit the game. Do this and you will end the game. No ifs,
ands or buts about it.
The mouse controls are active, and rather obvious:
Left Move left, as above
Middle Fire, as above
Right Move right. ditto.
SCORING
The lowest monsters are worth 10 points, the next are worth 20, and the
highest are worth 30. Space ships are worth anything from 50-300
points (in 50 point increments, of course).
CUSTOMIZING COLORS
As with all standard X applications, xinvaders may be customized
through entries in the resource manager. This game also works on
monochrome screens, but the colors don't mean anything (surprise!).
Scale A switch that allows for multiple resolutions. 1 for normal
resolution, 2 for 2x zoom (the default).
BaseColor
The color for the Base (you). Default is white.
BuildingColor
The color for the buildings that shield you. Default is yel‐
low.
Vader1Color
The color for the highest invaders. Default is blue.
Vader2Color
The color for the middle invaders. Default is orange.
Vader3Color
The color for the lowest invaders. Default is red.
SpacerColor
The color for the Space Ship. Default is gray.
ShotColor
The color for your shots. Default is green.
VshotColor
The color for their shots. Default is pink.
ScoreColor
The color for the score. Default is cyan.
Here's an example of some of the resources you can set (this would be
in your .Xdefaults file):
Vaders*Font: 9x15
Vaders*Scale: 2
Vaders*defaultfore: black
Vaders*defaultback: white
Vaders*Vader1Color: blue
Vaders*Vader2Color: green
Vaders*Vader3Color: red
Vaders*BaseColor: cyan
Vaders*BuildingColor: yellow

Vaders*BaseWait: 10
Vaders*VaderWait: 300
Vaders*SpacerWait: 50
Vaders*ShotWait: 10

NOTES
There are lots of resources. You can change all the timings involved.
Have fun with it.
Although you can resize the gamewindow, I don't recommend it.
BUGS
The buildings aren't as good as the arcade, but hey, whatdayawant for
free? It also doesn't handle auto-repeat very well, so you should
probably turn it off.
COPYRIGHT
This is mine. I'm only letting you use it. Period. Feel free to rip
off any of the code you see fit, but have the courtesy to give me
credit. Otherwise great hairy beasties will rip your eyes out and eat
your flesh when you least expect it.
CREDITS
I'd like to give a lot of credit to Terry Weissman for his roids games.
It gave me the guidance on how to do something like this.
