History:
========
1.31:
Fixed drawing order. Objects were being drawn in reverse.
1.3:
Many thanks to Thomas Boutell, he has contributed a
Windows port of XInvaders 3D. See README.win for more
information.
XInvaders 3D DOS port finished. XInvaders 3D will now run
as a full-screen 640x480x8 DOS game. For windows users it
will run in a DOS window just fine. I used DJGPP+Allegro
to port it. See README.dos for more information.
Added Vector-fonts. All text graphics have been
replaced with Vector-fonts. Gives the game a
cleaner look.
New player blinking routine. Player now cycles
through red colors, rather than being drawn
each alternate frame, when a new level
has been started.
New special effect: 1-UP indicator. When 7500pts
have been reached a new life is indicated by
a nice little vector 1-UP floating towards
the player.
New alien-shoot missile routine. Aliens now shoot
more.
New Distance-of-Point-to-Line routine, used for
collision detection.
Added fix for FreeBSD systems, thanks to Peter da Silva.
Fixed ZONE_HEIGHT bug in game.c, which was generating
bad pointers, thanks to Sam Bushell.
Cleaned up code, for portability reasons, thanks to
Thomas Boutell for his help.
Left-Shift key is no longer being used.
1.2:
Cleaned up some more code.
Adjusted formation movement.
Changed missile color to yellow, suggested by Mattia Engdeg.
Fixed some warnings which the pedantic flag generates,
thanks to Jarmo Pussinen for pointing them out.
1.1:
Fixed incompatible pointer warnings.
Fixed window manager bug which Bill Kendrick pointed out.
Windows were opening at an odd width and height under
the Enlightenment Window manager.
1.0:
Initial release.
