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...
