XInvaders(1)             USER COMMANDS               XInvaders(1)



NAME
     XInvaders - Shoot-em-up them nasty little bugs.

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.

     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  cus-
     tomized through entries in the resource manager.   This game
     also works on monochrome screens, but the colors don't  mean
     anything (surprise!).

     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*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,  and  even  the  shapes of the objects in the game
     (they are loaded at run-time from the .bit files).  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,  what-
     dayawant  for  free?  You also must be in the same directory
     as the executable for the images to load properly.  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.
