SYNOPSIS
xinvaders [-all_those_groovy_xtoolkit_switches]

DESCRIPTION
xinvaders 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 yellow.

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*VaderWait: 300

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.
