Wolfenstein 3D
==============

The original source release was made using the ``DEICE.EXE``
installer (DeIce) in the root directory.  (Basically a way to
split self-extracting zip files over multiple floppy disks.)
After execution, that installer will create the contents of
the ``WOLFSRC`` directory.  In the "installed" directory, the
the ``README.TXT``, ``RELEASE.TXT``, and ``LICENCE.DOC`` reside
in the ``README`` directory.  They are duplicated below.

RELEASE.TXT
-----------

::

  We are releasing this code for the entertainment of the 
  user community.  We don't guarentee that anything even 
  builds in here.  Projects just seem to rot when you leave 
  them alone for long periods of time.

  This is all the source we have relating to the original 
  PC wolfenstein 3D project.  We haven't looked at this 
  stuff in years, and I would probably be horribly embarassed 
  to dig through my old code, so please don't ask any questions 
  about it. The original project was built in borland c++ 3.0.  
  I think some minor changes were required for later versions.

  You will need the data from a released version of wolf or spear 
  to use the exe built from this code.  You can just use a 
  shareware version if you are really cheap.


  Some coding comments in retrospect:

  The ray casting refresh architecture is still reasonably 
  appropriate for the game.  A BSP based texture mapper could 
  go faster, but ray casting was a lot simpler to do at the time.

  The dynamically compiled scaling routines are now a Bad Thing.  
  On uncached machines (the original target) they are the fastest 
  possible way to scale walls, but on modern processors you just 
  wind up thrashing the code cash and wrecking performance.  
  A simple looping texture mapper would be faster on 486+ machines.

  The whole page manager caching scheme is unecessarily complex.

  Way too many #ifdefs in the code!


  Some project ideas with this code:

  Add new monsters or weapons.

  Add taller walls and vertical motion.   This should only be 
  done if the texture mapper is rewritten.

  Convert to a 32 bit compiler.  This would be a fair amount 
  of work, but I would hate to even mess with crusty old 16 
  bit code.  The code would get a LOT smaller.

  Make a multi-player game that runs on DOOM sersetup / ipxsetup drivers.


  Have fun...
