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*Vader1Color:            blue
        Vaders*Vader2Color:            green
        Vaders*Vader3Color:            red
        Vaders*BaseColor:              cyan
        Vaders*BuildingColor:          yellow
        Vaders*SpacerColor:            gray
        Vaders*ShotColor:              lavender
        Vaders*VshotColor:             orange
        Vaders*BaseWait:               10
        Vaders*VaderWait:              300
        Vaders*SpacerWait:             50
        Vaders*ShotWait:               10
        Vaders*VshotWait:              30

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.
